Description

  The present invention relates to an electronic device having an operation input means for operating a graphical user interface arranged on an operation screen of a display, an operation input control method for the electronic device, and an operation input control program for the electronic device.

  Conventionally, electronic devices equipped with an input device such as a touch panel, a touch pad, and a pen tablet have been widely used. Since such an input device is easy to understand the operation intuitively, it contributes to improving the operability of the electronic device. On the other hand, there is a risk of incorrect operation due to unintended contact. For this reason, various proposals have been made from the viewpoint of preventing erroneous operations (see Patent Documents 1 and 2).

In Patent Literature 1, an attribute relationship between touch switches on a touch panel is determined in advance, and an operation is accepted when touch switches having the same attribute relationship are simultaneously operated. In Patent Document 2, the touch time on the touch panel is detected, and an operation is accepted when the touch time exceeds a threshold value. In addition, when the contact time is continuously equal to or less than the threshold value for a predetermined number of times, the threshold value is shortened to deal with users who tend to have a short contact time.
Japanese Patent Laid-Open No. 06-187097 JP 2007-109082 A

  The method of Patent Document 1 that accepts an operation when touch switches having the same attribute relationship are operated at the same time cannot perform one operation unless a plurality of touch switches are operated. Easyness is impaired. Furthermore, operation with fingers is assumed, and it cannot be used for a stylus (a stick-like instrument for operating a touch panel device).

  In the method of Patent Document 2 that accepts an operation when the contact time exceeds a threshold value, if the threshold value is too long, the operability deteriorates, and if it is too short, an operation that needs to be confirmed is accepted immediately and the effect of preventing erroneous operation is reduced. To do.

  The present invention has been made in view of the above problems, and an object of the present invention is to realize smooth operability when an operation without importance is performed and to prevent erroneous operation with an operation with importance.

  In order to achieve the above object, an electronic apparatus according to the present invention includes an operation input unit, an operation state detection unit, a threshold setting unit, and first and second determination units.

  The operation input means is an input device for operating a plurality of operation tools on an operation screen configured by a graphical user interface. The operation input unit is, for example, any one of a touch panel, a touch pad, and a pen tablet. In addition, a keyboard, a mouse, a joystick, a trackball, or the like may be used.

  The operation state detection unit detects at least one of an operation state of the operation input unit, for example, an operation pressure applied to the operation input unit, or an operation time of the operation input unit.

  Informing means for informing the operation time of the operation input means by the operation state detecting means and notifying the time taken to accept the operation when an operation tool having a high importance level is selected via the operation input means. It is preferable to provide.

  In the threshold value setting means, a threshold value for comparison with the detection result of the operation state detection means is set for each important level of operation defined in advance for each operation tool.

  In a preferred embodiment of the present invention, the threshold value setting means is configured to be able to change the threshold value in accordance with an operation input from the operation input means. The threshold setting unit manages the threshold for each user.

  The critical level depends on the high need to ascertain whether the operator has made a clear will. An operation tool with a high importance level is related to, for example, final registration when information is registered or changed.

  The first determination unit detects an operation position in the operation screen pointed to by the operation input unit, and determines an operation target of the operation input unit from a plurality of operation tools. In addition, when the said operation input means is said touch panel, a touchpad, and a pen tablet, these also serve as the function of the 1st determination means of detecting an operation position. In the case of a mouse, a mouse ball or an infrared sensor corresponds to the above function.

  The second determination unit compares the detection result of the operation state detection unit with a threshold value, and determines whether or not to accept an operation of the operation tool determined as the operation target by the first determination unit. When the threshold value of the operation tool having a high importance level is set higher than that of the operation tool having a low importance level, the second determination unit accepts an operation when the detection result of the operation state detection unit exceeds the threshold value.

  In a preferred embodiment of the present invention, the electronic device is a radiographic image processing apparatus that cooperates with a radiographic imaging apparatus.

  An operation input control method for an electronic device according to the present invention includes an operation state detection step of detecting an operation state of an operation input unit for operating a plurality of operation tools on an operation screen configured by a graphical user interface by an operation state detection unit. And a first determination step of detecting an operation position in the operation screen pointed to by the operation input unit by the first determination unit and determining an operation target of the operation input unit from among a plurality of operation tools; Whether the operation of the operation tool to be operated is accepted by comparing the threshold value set for each operation importance level predefined for each operation tool with the detection result of the operation state detection step by the second determination means And a second determination step for determining whether or not.

  An operation input control program for an electronic device according to the present invention includes an operation state detection function for detecting an operation state of an operation input unit for operating a plurality of operation tools on an operation screen configured by a graphical user interface, and an operation input unit. A first determination function that detects an operation position in the operation screen to be pointed and determines an operation target of the operation input means from among a plurality of operation tools, and each important level of operation defined in advance for each operation tool And a second determination function for comparing the detection result of the operation state detection function and determining whether or not to accept an operation of the operation tool to be operated is executed by the computer. And

  According to the present invention, a threshold value is set for each operation importance level defined in advance for each operation tool, and whether to accept an operation based on the comparison result of the threshold value and the detection result of the operation state of the operation input means. So, for example, if you set the threshold of the operation tool with a high importance level higher than the operation tool with a low importance level, and accept the operation when the detection result of the operation state exceeds the threshold, An operation without importance realizes smooth operability, and an operation with importance can prevent an erroneous operation.

  In FIG. 1, the modality 2 includes an X-ray imaging apparatus 10 and an operation terminal 11. The X-ray imaging apparatus 10 has a well-known mechanism for irradiating a subject (human body) H with X-rays and imaging the inside of the subject H, and includes an X-ray tube 12 and an imaging table 13. And an imaging plate (hereinafter abbreviated as IP) 14 and the like.

  The X-ray tube 12 generates X-rays by accelerating electrons to enter a target such as tungsten or molybdenum from a cathode filament. The quality and dose of X-rays exposed from the X-ray tube 12 vary according to the current (tube current) flowing through the cathode, the acceleration voltage (tube voltage), and the like.

  The X-ray tube 12 is installed on the ceiling of the radiographing room by a support arm (not shown). The X-ray tube 12 is supported by the support arm so as to be movable up and down and left and right around the imaging table 13. Moreover, it is rotatably supported within a predetermined angle so that the direction of X-ray exposure can be changed. Thereby, X-rays are exposed toward an arbitrary part of the subject H lying on the imaging table 13. The X-ray tube 12 is provided so as to be manually movable, and is moved in the vertical direction while keeping the distance from the IP 14 constant following the elevation of the imaging table 13.

  The imaging table 13 is installed on the floor of the imaging room and has a movable support column that expands and contracts so that the height from the floor can be adjusted. The portion of the imaging table 13 on which the subject H lies is made of a material through which X-rays exposed from the X-ray tube 12 are transmitted almost completely so that the imaging table 13 does not appear in the X-ray image 15.

  The IP 14 is made of a stimulable phosphor such as a barium fluorohydride compound doped with europion ions, and is loaded in a cassette or the like. The IP 14 has an area that covers the entire chest of the subject H, and is arranged on the back surface of the imaging table 13 with the imaging surface facing the ceiling of the imaging room. The IP 14 is provided so as to be movable in the longitudinal direction of the imaging table 13, and moves to a position where X-rays can be received efficiently following the movement or change of direction of the X-ray tube 12.

  A latent image is recorded on the IP 14 by X-ray exposure. The IP 14 after the latent image recording is scanned with laser light by a reading device (not shown). The reading device detects the stimulated light emission excited by the irradiation of the laser light, performs processing such as logarithmic conversion amplification, A / D conversion, and the like, and outputs the digital signal to the operation terminal 11.

  The operation terminal 11 includes a display 16 and an input device 17 such as a keyboard and a mouse. On the upper surface of the display 16, a touch panel 18 and a pressure sensor 19, both of which are made of a transparent material, are stacked (see also FIG. 2). The touch panel 18 detects the contact position of the finger F (see FIG. 10) using a known method such as a resistive film method or a capacitance method. The pressure sensor 19 detects the contact pressure of the finger F on the touch panel 18.

  The operation terminal 11 sets the imaging conditions of the X-ray imaging apparatus 10 (X-ray tube 12), that is, the tube voltage and the tube current time product (exposure amount), when registering information on the patient who is the subject H. When the image processing is performed, the X-ray image 15 obtained by the X-ray imaging apparatus 10 is operated. A user who operates the operation terminal 11 is, for example, a medical radiographer (hereinafter simply referred to as an engineer). The operation terminal 11 displays various operation screens, which will be described later, on the display 16 and supports the image processing of the X-ray image 15 by the engineer.

  The data of the X-ray image 15 has an image ID for identifying each X-ray image 15. The data of the X-ray image 15 is stored in the operation terminal 11 in a file format conforming to DICOM (Digital Imaging and Communication in Medicine), for example.

  The file of the X-ray image 15 is provided with a data storage area for the X-ray image 15 and a DICOM tag. The DICOM tag is provided with fields for storing items of examination information such as patient information such as patient ID and patient name, examination ID, examination date and time, and imaging conditions of the X-ray imaging apparatus 10. The file of the X-ray image 15 can be searched using various items of the DICOM tag as search keys.

  The operation terminal 11 is configured by installing a control program such as an operating system and an application program based on a computer such as a personal computer or a workstation.

  In FIG. 2, the computer constituting the operation terminal 11 includes a CPU 30, a memory 31, a storage device 32, and a LAN port 33 in addition to the display 16, the input device 17, the touch panel 18, and the pressure sensor 19 described above. . These are interconnected via a data bus 34.

  The storage device 32 is, for example, an HDD (Hard Disk Drive). In addition to the X-ray image 15 file, the storage device 32 stores a control program and an application program (hereinafter referred to as AP) 35.

  The memory 31 is a work memory for the CPU 30 to execute processing. The CPU 30 loads the control program stored in the storage device 32 into the memory 31 and executes processing according to the program, thereby comprehensively controlling each part of the computer. The LAN port 33 is a network interface that performs transmission control with a network such as a LAN (Local Area Network).

  In the operation terminal 11, an application program (hereinafter referred to as an X-ray image processing program) for performing image processing of the X-ray image 15 and setting of imaging conditions is installed as the AP 35.

  In FIG. 3, when the X-ray image processing program is started, the CPU 30 of the operation terminal 11 functions as a control unit (corresponding to first and second determination means) 40, an image processing unit 41, and a transmission / reception unit 42.

  The control unit 40 outputs a patient information registration screen 43 on the display 16. Various operation tools constituting a graphical user interface (hereinafter abbreviated as GUI) are arranged on the patient information registration screen 43. The operation tool is a general GUI component such as various input boxes, menus, bars, buttons, icons, windows, and dialogs described later. Through these operation tools, various operation instructions are input from the input device 17 or the finger F. In the following description, the description will focus on the operation instruction by the finger F.

  The patient information registration screen 43 is provided with a plurality of input boxes 44 for inputting various items of patient information such as patient ID, patient name, sex, date of birth. When the finger F is brought into contact with the position of the input box 44, the input box 44 becomes active, and patient information can be input. The patient information registration screen 43 is provided with a screen transition button 45 that is operated when the operation screen is transitioned.

  Furthermore, the patient information registration screen 43 is provided with an alphabet key button 46, a numeric keypad 47, and a registration button 48 for inputting patient information. The registration button 48 is selected when registering the patient information after the patient information has been input.

  When the registration button 48 is selected, the control unit 40 displays a warning dialog 50 shown in FIG. In the warning dialog 50, an OK button 51 and a Cancel button 52 are displayed together with a message for final confirmation of registration of patient information. When the OK button 51 is selected, the control unit 40 stores the patient information input at that time in the input box 44 in a patient information table (not shown) of the storage device 32. When the Cancel button 52 is selected, the control unit 40 closes the warning dialog 50. In addition, in the patient information registration screen 43, it is possible to correct the patient information stored in the patient information table as well as register patient information of a new patient.

  In FIG. 5, in response to the operation of the screen transition button 45, the control unit 40 outputs a shooting condition setting screen 55 to the display 16. The imaging condition setting screen 55 includes a selection button 56 for selecting an imaging region such as an examination site such as the head and chest, the front, the side, and P → A, and a tube for adjusting the tube voltage of the X-ray tube 12. Operation tools for setting imaging conditions of the X-ray imaging apparatus 10 such as a voltage adjustment unit 57 and a tube current time product adjustment unit 58 for adjusting the tube current time product are arranged. Each adjustment unit 57, 58 displays a current set value, and a +/- button for increasing / decreasing the set value is arranged on the side.

  The shooting condition setting screen 55 is provided with a setting button 59. The setting button 59 is selected when setting the shooting conditions after the input of the shooting conditions.

  When the setting button 59 is selected, the control unit 40 displays a warning dialog 65 shown in FIG. In the warning dialog 65, an OK button 66 and a Cancel button 67 are displayed together with a message for confirming the final setting of the photographing conditions. When the OK button 66 is selected, the control unit 40 transmits the imaging conditions set in the selection button 56 and the adjustment units 57 and 58 at that time to the X-ray imaging apparatus 10 via the transmission / reception unit 42. To do. When the Cancel button 67 is selected, the control unit 40 closes the warning dialog 65.

  In FIG. 7, the control unit 40 outputs the image processing screen 70 to the display 16 in response to the operation of the screen transition button 45. The image processing screen 70 is provided with an X-ray image 15, a blackening processing button 71, and an S value (reading sensitivity value) / L value (latitude) adjustment button 72. When the finger F is brought into contact with various operation tools on the operation screens 43, 55, and 70, the operation input is received by the control unit 40, and the control unit 40 executes processing according to the operation input.

  The image processing unit 41 performs various types of image processing on the data of the X-ray image 15 received from the X-ray imaging apparatus 10 via the transmission / reception unit 42. Image processing includes blackening processing and histogram analysis in addition to basic image processing such as noise removal, gain adjustment, and gradation processing.

  The image processing unit 41 performs blackening processing when the blackening processing button 71 on the image processing screen 70 is selected. In the blackening process, the pixel value of each pixel of the X-ray image 15 (for example, represented by a 10-bit gradation of 0 (white) to 1023 (black)) is analyzed, and the X-ray is applied to the subject H. This is a process of recognizing a missing region that is missing without hitting, and painting the missing region in black. In recognition of the blank region, first, binarization processing is performed on the data of the X-ray image 15 to make the X-ray image 15 a black and white binary image, and labeling processing is performed on the binary image. Then, the background missing area and the other areas are identified and extracted. Since a method for recognizing a certain region by binarization + labeling processing is well known, detailed description thereof is omitted.

In addition, the image processing unit 41 performs histogram analysis on the data of the X-ray image 15 and calculates the S value and the L value. Specifically, as shown in FIG. 8, the main histogram (range from Smin to Smax) is determined according to the examination site, and Qmin of 10-bit gradation values from 0 to 1023 is set for each of Smin and Smax. Qmax is applied. At this time, the dose width represented by the gradation values of 0 to 1023 is the L value. The S value is obtained by the following equation using the dose Sk corresponding to the middle point 511 of the gradation value.
S = 4 × 10 ^(4-Sk)

  When the S value / L value adjustment button 72 on the image processing screen 70 is selected, the control unit 40 causes the image processing screen 70 to display an operation tool (not shown) for adjusting the S value and the L value. When the S value and L value are adjusted, the image processing unit 41 performs image processing again with the S value and L value at that time. In response to this, the control unit 40 updates the display of the X-ray image 15.

  The image processing unit 41 performs various types of image processing such as gradation processing based on the histogram analysis result, and then hands over the data of the X-ray image 15 to the control unit 40. The control unit 40 converts the data from the image processing unit 41 into the display format of the display 16 and displays it as the X-ray image 15 on the image processing screen 70.

  The transmission / reception unit 42 receives the data of the X-ray image 15 from the X-ray image capturing apparatus 10 and transmits the data of the imaging conditions to the X-ray image capturing apparatus 10.

  In FIG. 9, contact position data, contact pressure data, and contact time data are input to the control unit 40 from the touch panel 18, the pressure sensor 19, and the timer 75, respectively. The contact position data represents the contact position of the finger F on the touch panel 18, for example, two-dimensional X and Y coordinates with the dot in the left corner of the display 16 as the origin and the vertical direction as the X axis and the horizontal direction as the Y axis. It is expressed by The contact pressure data indicates the contact pressure of the finger F on the touch panel 18 and is a digital signal obtained by A / D converting the analog output of the pressure sensor 19. The contact time data indicates how long the finger F has been in contact with the touch panel 18 with a contact pressure equal to or higher than a threshold, which will be described later, and is represented by a clock pulse emitted from the timer 75.

  A threshold table 76 is stored in the storage device 32 of the operation terminal 11. The threshold value table 76 defines two levels of level 0 and level 1 representing the importance of the operation for various operation tools on the operation screens 43, 55, and 70, and the contact pressure and the contact for each level. Give a time threshold. Each threshold is a value for accepting an operation when the contact with the finger F is continued for a longer time at a higher pressure.

  Operation tools classified as level 0 are less likely to be checked by the engineer with a clear will. In this example, the input box 44 of the patient information registration screen 43, the alphabet key button 46, the numeric keypad 47, the registration button 48, the Cancel button 52 of the warning dialog 50, the selection button 56 of the imaging condition setting screen 55, and the tube voltage adjustment unit 57. , Tube current time product adjustment unit 58, setting button 59, cancel button 67 of warning dialog 65, and screen transition button 45.

  Contrary to the case of level 0, the operation tool classified as level 1 is highly necessary to confirm whether or not the engineer has selected with a clear will. In this example, the OK button 51 of the warning dialog 50, the OK button 66 of the warning dialog 65, the blackening processing button 71 of the image processing screen 70, and the S value / L value adjustment button 72 correspond.

  If patient information is entered incorrectly, it may lead to misdiagnosis such as patient misunderstanding. The imaging conditions and image processing need to be changed after confirming that the interpretation of the X-ray image 15 is not affected. For this reason, each of the above-described operation tools related to registration and setting change is classified as level 1.

  Level 1 contact pressure and contact time thresholds Pim and Tim are set higher than level 0 contact pressure and contact time thresholds Pst and Tst (Pim> Pst, Tim> Tst). Therefore, in order to make the operation of the level 1 operation tool effective, the finger F must be kept in contact with the contact pressure stronger than that of the level 0 for a long time. From the viewpoint of the level 0 operation tool, the operation can be validated with a contact pressure weaker than that of the level 1 and with a short contact time.

  For example, values close to 0 are set for the threshold values Pst and Tst, and values that are several times to several tens of times the threshold values Pst and Tst are set for the threshold values Pim and Tim, for example. Alternatively, the threshold values Pst and Tst may be set to 0. In this case, the operation becomes effective as soon as the finger F touches the touch panel 18, and detection of the contact pressure and the contact time does not make sense.

  When the control unit 40 receives the contact position data from the touch panel 18, the control unit 40 refers to a table (not shown) that associates the contact position with the position where the operation tool is arranged, and determines which operation tool has been selected. . If the finger F comes into contact with a portion without the operation tool and the operation tool cannot be determined, the control unit 40 ends the process. When determining the operation tool, the control unit 40 refers to a table (not shown) in which the operation tool is associated with its level, and whether the determined operation tool belongs to the level 0 or level 1 classification. Is further determined.

  When the operation tool is level 0, the control unit 40 reads the threshold values Pst and Tst of level 0 from the threshold value table 76. Then, the threshold value Pst and the contact pressure data from the pressure sensor 19 are compared. When the contact pressure is insufficient and the contact pressure data does not exceed the threshold value Pst, the control unit 40 does nothing.

  When the contact pressure data exceeds the threshold value Pst, the control unit 40 activates the timer 75 and compares the threshold value Tst with the contact time data. When the contact time data does not exceed the threshold value Tst, the control unit 40 does nothing. When the contact time data exceeds the threshold value Tst, the control unit 40 receives an operation of the operation tool and executes a process corresponding to the operation tool.

  If the contact pressure data falls below the threshold value Pst before the contact time data exceeds the threshold value Tst, the control unit 40 stops the timer 75 and stops the comparison between the threshold value Tst and the contact time data. When the contact pressure data exceeds the threshold value Pst again, the operation of the timer 75 and the comparison of each value are repeated. That is, the operation is accepted when the contact pressure data exceeds the threshold value Pst and the contact time data exceeds the threshold value Tst. When the operation tool is level 1, only the threshold value described above is replaced with Pim and Tim, and the description is omitted.

  As shown in FIG. 10, when the determined operation tool belongs to level 1, the control unit 40 exceeds the threshold value Pim, and the timer 75 is activated to compare the threshold value Tim with the contact time data. In addition, a progress bar 80 is displayed indicating how much finger F should be touched. The figure shows a state in which the finger F is in contact with the OK button 51 of the warning dialog 50 and the progress bar 80 is displayed in the warning dialog 50.

  The progress bar 80 is indicated by a colored bar (hatched part) that extends from left to right as the contact time elapses, and the remaining time is indicated by a part without the bar. The control unit 40 updates the display of the progress bar 80 based on the difference between the threshold value Tim and the contact time data, and deletes the warning dialog 50 including the progress bar 80 when the contact time data exceeds the threshold value Tim. When the operating tool is level 0, the progress bar 80 is not displayed, and the progress bar 80 is not displayed because the threshold Tst is short.

  Next, the processing procedure of modality 2 will be described. First, registration of patient information and setting of imaging conditions are performed on the patient information registration screen 43 and imaging condition setting screen 55 of the operation terminal 11, and then imaging is performed by the X-ray imaging apparatus 10. Then, X-ray image 15 data is transmitted from the X-ray imaging apparatus 10 to the operation terminal 11.

  Data of the X-ray image 15 is input to the image processing unit 41 via the transmission / reception unit 42. In the image processing unit 41, histogram analysis is performed to calculate an S value and an L value, and image processing such as gradation processing is performed based on the result. The X-ray image 15 image-processed by the image processing unit 41 is displayed on the image processing screen 70 by the control unit 40.

  The engineer observes the X-ray image 15, selects the blackening process button 71 and the S value / L value adjustment button 72 as necessary, and performs image processing on the X-ray image 15. The data of the X-ray image 15 that has been subjected to various types of image processing is stored in the storage device 32 in the DICOM file format.

  As shown in the flowchart of FIG. 11, in the operation terminal 11, the touch position of the finger F is detected by the touch panel 18 (S10). When the finger F touches the touch panel 18 (YES in S10), contact position data is input from the touch panel 18 to the control unit 40 (S11). The control unit 40 determines which operation tool has been selected and whether it belongs to the level 0 or level 1 classification (S12).

  When the operation tool is level 0 (YES in S13), the threshold values Pst and Tst of level 0 are read from the threshold value table 76 to the control unit 40 (S14). When the operation tool is level 1 (NO in S13), the threshold values Pim and Tim are read (S15). Subsequent processing is performed based on the threshold value read at this time.

  The control unit 40 compares the threshold value Pst or Pim with the contact pressure data from the pressure sensor 19 (S16). When the contact pressure data exceeds the threshold value (YES in S17), the control unit 40 activates the timer 75 and compares the threshold value Tst or Tim with the contact time data (S18). When the contact time data exceeds the threshold value (YES in S19), the operation is accepted and processing corresponding to this is executed (S20).

  If the contact pressure data falls below the threshold value (NO in S17) before the contact time data exceeds the threshold value (NO in S19), the timer 75 is stopped. When the contact pressure data again exceeds the threshold value (YES in S17), the operation of the timer 75 and the comparison of each value are repeated. These series of processes are continued until the operation ends (YES in S21).

  As described above, the contact pressure and contact time of the finger F on the touch panel 18 are detected, the important level of operation of the operation tool is defined, and the threshold values of the contact pressure and the contact time are higher than those with a lower importance level. Is set high, and it is determined whether to accept the operation based on the comparison result of the contact pressure and contact time data and the threshold value. Good operability can be provided for an operation tool with a low level of importance.

  Since the progress bar 80 is displayed to indicate the time taken to accept the operation, the engineer can be given time to consider whether or not the operation can be confirmed. Moreover, the irritability of operation can be eased. Note that the means for notifying the time taken to accept the operation is not limited to the progress bar 80, and may be indicated by counting up or down a number, or by a voice message.

  As another measure for alleviating the irritability of the operation, it is conceivable to display a message indicating that the contact pressure or the contact time is insufficient when the same position of the touch panel 18 is operated continuously for a predetermined number of times. By doing so, it is possible to diminish the impression that the operability of the operation tool having a high importance level is relatively poor.

  In the above embodiment, the threshold values of the contact pressure and the contact time are fixed, but these may be configured to be changeable according to the operation input of the input device 17 or the like. However, the threshold of level 0 cannot be set higher than level 1 or a setting allowable range is set. The threshold value can be set short for a prudent person and long for a careful person, and the setting can be made according to the personality and preference of the engineer.

  In the above embodiment, as an example of the operation tool corresponding to level 1, the OK button 51 of the warning dialog 50, the OK button 66 of the warning dialog 65, the blackening processing button 71 of the image processing screen 70, and the S value / L value adjustment Although the button 72 is mentioned, it is not limited to these.
