Description

  The present invention relates to an image processing device, a control method therefor, and a program, and more particularly to an image processing device that corrects image data obtained by shooting.

  Generally, the brightness of image data obtained by an image pickup device such as a digital camera is adjusted based on a user's setting. Furthermore, not only brightness but also image data is corrected by combining a plurality of parameters such as brightness, saturation, and white balance.

  For example, there is an image processing apparatus that displays the first corrected image data generated based on the color information selected by the user at the upper and lower positions of the captured image data in correspondence with the increase or decrease of the color information ( See Patent Document 1). In Patent Document 1, further, the second corrected image data generated based on the brightness information is displayed at the left and right positions of the image data before the correction processing in correspondence with the increase or decrease of the brightness information.

  Further, there is an image processing apparatus that displays a plurality of samples corresponding to a plurality of parameters when printing with a printer and processes image data according to the parameters of the selected sample (see Patent Document 2).

  In the above-mentioned Patent Documents 1 and 2, it is described that the image processing is performed according to the parameter according to the selection by the user. On the other hand, when it takes several seconds to correct one image like the RAW data development process, it is necessary to display the correction results (that is, the corrected images) of a plurality of images as a list. It takes a lot of time. Therefore, the waiting time of the user until the list of correction results is displayed on the display unit increases.

  Furthermore, if the correction image desired by the user does not exist in the list of correction images displayed on the screen, the user needs to perform another scroll process such as up, down, left, and right to display another correction image. Then, in the image processing devices described in Patent Documents 1 and 2, it is necessary to generate a plurality of corrected images each time scroll processing is performed. As a result, the user not only has a long waiting time until a desired corrected image is obtained, but also the operability deteriorates.

  Therefore, an object of the present invention is to provide an image processing apparatus, a control method thereof, and a program capable of obtaining a desired corrected image in a short time and with a simple operation.

In order to achieve the above object, an image processing apparatus according to the present invention is an image processing apparatus that performs image processing on a target image that is a target of image processing using a plurality of correction parameters, and the plurality of corrections are performed on the target image. First display control means for displaying on the display unit the correction candidate images, which are the results of image processing using each of the parameters, as one group for each of the correction parameters, and one correction candidate image from the correction candidate images. Selecting means for selecting as a selected image, and a second image processing means for image-processing the selected image using a correction parameter different from the correction parameter used in the selected image and displaying the result in a predetermined area of the display unit. possess a display control unit, wherein the there are a plurality of first and second parameters as a correction parameter, said first display control means, the image processing by the correction candidate with the first parameter The images are displayed side by side in a predetermined direction on the display unit, and the correction candidate images subjected to image processing using the second parameter are displayed side by side in a direction intersecting the predetermined direction on the display unit, and the selection is performed. When one of the correction candidate images image-processed by the means using the first parameter is selected as the selected image, the second display control means fixes the first parameter for the selected image. Then, a first display process of displaying the result of image processing of the selected image using the second parameter on the display unit is performed .

  According to the present invention, a plurality of correction candidate images can be displayed in a list, and a desired correction image can be obtained by a simple operation in a short time.

  An example of the image processing apparatus according to the embodiment of the present invention will be described below with reference to the drawings.

[First Embodiment]
FIG. 1 is a block diagram showing the configuration of an example of an image processing apparatus according to an embodiment of the present invention.

  The illustrated image processing apparatus 100 includes a display unit (LCD) 101, a VRAM 102, a BMU 103, a keyboard 104, and a pointing device (PD) 105. Further, the image processing apparatus 100 has a CPU 106, a ROM 107, a RAM 108, an HDD 109, an FDD 110, and a network I/F 111.

  On the LCD 101, for example, image data recorded in the image processing apparatus 100, other editing information, icons, messages, menus, and user interface information are displayed. Image data to be displayed on the LCD 101 is drawn in the VRAM 102. The image data drawn in the VRAM 102 is transferred to the LCD 101 according to a predetermined rule, and the image is displayed on the LCD 101.

  A BMU (bit move unit) 103 controls, for example, data transfer between memories (between the VRAM 102 and another memory) and data transfer between a memory and an I/O device (for example, a network I/F 111). . The keyboard 104 is used when performing image editing information and image-related operations, and includes various keys.

  The PD 105 is used, for example, when instructing icons, menus, and other contents displayed on the LCD 101 or selecting an object. The CPU 106 controls each device based on a control program stored in the ROM 107, the HDD 109, or a flexible disk (not shown).

  Various control programs and data are stored in the ROM 107. The RAM 108 has a work area for the CPU 106, a data save area for error processing, and a control program load area. The HDD 109 stores a control program executed by the image processing apparatus 100 and image data. The FDD 110 is a flexible disk typified by a floppy disk (registered trademark) for access. The network I/F 111 is an interface for connecting to a network line 113 such as the Internet. The CPU bus 112 is provided with an address bus, a data bus, and a control bus.

  Although the control program is provided to the CPU 106 from the ROM 107, the HDD 109, or the FDD 110, it may be provided from an external information processing device or the like via the network I/F 111.

  FIG. 2 is a diagram showing an example of a correction screen displayed on the LCD shown in FIG. Then, FIG. 2A is a diagram showing an example of an initial state of image correction, and FIG. 2B is a diagram showing an example of a display when a correction candidate image according to the first parameter is selected. And FIG.2(c) is a figure which shows an example of a display when scrolling about a correction candidate image.

  In FIG. 2A, a correction screen (also referred to as a display screen) 200 has an area (correction candidate display area) 201, and the correction candidate display area 201 is corrected according to image correction using two parameters. A candidate image (also called a correction result) is displayed. In the initial state, the correction result is not displayed in the correction candidate display area 201.

  The image 202 is an image to be corrected, that is, an image before correction. The OK button 203 is operated when ending the image correction and saving the correction result. The cancel button 204 is operated when canceling the image correction. The first scroll buttons 211 and 212 are used when scroll-displaying the first parameter. The first scroll buttons 211 and 212 are used when there are no desired correction candidate images among the correction candidate images 213 to 218 obtained as a result of the correction processing using the first parameter.

  The second scroll buttons 221 and 222 are used when scroll-displaying the second parameter. The second scroll buttons 221 and 222 are used when there is no desired correction candidate image among the correction candidate images 223 to 227 obtained as a result of the correction processing using the second parameter.

  Both the first and second parameters are correction parameters. Then, the correction candidate images obtained using the first and second parameters are arranged on the display screen 200 in directions intersecting with each other. The first parameter is, for example, a parameter used when adjusting (correcting) the brightness of the image, and the user can adjust the brightness of the image by changing the value of the first parameter. The second parameter is, for example, a parameter used when adjusting brightness, saturation, or white balance. The user can adjust the brightness, saturation, or white balance by adjusting the value of the second parameter.

  FIG. 2B shows an example when the user selects the image 215 in the correction candidate images 213 to 218 obtained as a result of the correction processing using the first parameter. That is, the corrected image data for each correction parameter is shown as one group. Further, the scrolling described above is performed for each group.

  Now, when the user selects the image 215, the CPU 106 fixes the first parameter for the correction target image 202. Then, the CPU 106 vertically displays the correction candidate images 233 to 237, which are obtained when the correction target image is corrected using the second parameters corresponding to the images 223 to 227, in the correction candidate display area 201.

  Note that the user may select any one of the correction candidate images 223 to 227 using the second parameter without selecting the correction candidate images 213 to 218 using the first parameter. At this time, the CPU 106 fixes the second parameter and performs the correction process using the first parameter corresponding to the correction candidate images 213 to 218 as described above to display the correction candidate image as the correction candidate. It is displayed in the area 201. At this time, the CPU 106 displays the correction candidate images side by side in the correction candidate display area 201.

  FIG. 2C shows a display example when the second scroll button (down scroll button) 222 related to the second parameter is operated after selecting the correction candidate image using the first parameter. ing.

  When the second scroll button 222 is operated, the CPU 106 scrolls the correction candidate images 223 to 227 using the second parameter upward by one image, and the correction candidate images 224 to 227 and a new correction candidate image 228. Are displayed vertically. Further, the CPU 106 correction candidate images 233 to 237 are scrolled up by one image, and a new correction candidate image 238 is displayed in the correction candidate display area 201 together with the correction candidate images 234 to 237.

  Note that the scrolling process described with reference to FIG. 2C is similarly performed on the correction candidate image using the first parameter.

  FIG. 3 is a diagram showing another example of the correction screen displayed on the LCD shown in FIG. And FIG.3(a) is a figure which shows an example of a display when the correction candidate image which concerns on a 2nd parameter is selected. 3B is a diagram showing an example of a screen displayed on the LCD when the user selects an arbitrary position in the correction candidate display area.

  Now, it is assumed that the correction candidate image 235 is selected from the correction candidate images 233 to 237 displayed in the correction candidate display area 201 by the user. When the correction candidate image 235 is selected, the CPU 106 displays the correction candidate images 244 to 246 and 254 to 256 around the correction candidate image 235 as described later (FIG. 3A).

  On the other hand, when the user selects an arbitrary position in the correction candidate display area, the CPU 106 calculates the first parameter and the second parameter used for correction according to the selected position, as described later. Then, the CPU 106 performs a selection display process of selectively displaying the correction candidate image assuming that the calculated first parameter and second parameter are selected.

  FIG. 4 is a diagram showing an image management table for managing paths of correction candidate images in the image processing apparatus shown in FIG.

  As described above, when the correction candidate image is generated using the first or second parameter, the CPU 106 records the correction candidate image in the HDD 109, for example. Further, the CPU 106 registers the image path indicating the correction candidate image in the image management table 300 stored in the HDD 109.

  Note that once the correction candidate image is generated, if the correction candidate image using the same parameter is required again, the CPU 106 refers to the image path registered in the image management table 300 without performing the image correction each time. Then, the required correction candidate image is acquired. Thereby, the correction process and the display process can be speeded up.

  In FIG. 4, the first area 301 is an area for managing the first parameter, and the second area 302 is an area for managing the second parameter. In the third area 303, an image path (correction candidate) which is a recording destination of a correction candidate image obtained by using the first and second parameters registered in the first area 301 and the second area 302, respectively. The image path) is registered.

  FIG. 5 is a flowchart for explaining a correction candidate image selection process performed by the image processing apparatus shown in FIG. The processing according to the illustrated flowchart is performed under the control of the CPU 106.

  When the correction candidate image selection process is started, the CPU 106 generates correction candidate images 213 to 218 (see FIG. 2A) using the first parameter and displays them on the display screen 200 (step S401). Further, the CPU 106 generates correction candidate images 223 to 227 using the second parameter and displays them on the display screen 200 (step S402). At this time, the CPU 106 displays the correction target image 202, the scroll buttons 211, 212, 221, 222, and the like on the display screen 200.

  The display screen 200 shown in FIG. 2A is displayed on the LCD 101 by the processes of steps S401 and S402.

  Subsequently, the CPU 106 determines whether or not there is an input action by the user (here, a touch action of touching the display screen) (step S403). If there is no touch action (NO in step S403), CPU 106 waits.

  If there is a touch action (YES in step S403), CPU 106 determines whether or not the touch action is a scroll operation (referred to as a first scroll operation) on the correction candidate image based on the first parameter (step S404). .. If the touch action is the first scroll operation (YES in step S404), CPU 106 performs the scroll process related to the first parameter as described later (step S405). Hereinafter, this scroll processing is referred to as the first scroll processing.

  If the touch action is not the first scroll operation (NO to the step S404), the CPU 106 determines whether or not it is a scroll operation (referred to as a second scroll operation) on the correction candidate image based on the second parameter (step S404). S406). If it is the second scroll operation (YES to the step S406), the CPU 106 performs a scroll process relating to the second parameter as described later (step S407). Hereinafter, this scroll processing is referred to as the second scroll processing.

  If the touch action is not the second scroll operation (NO in step S406), CPU 106 determines whether or not the correction candidate image is selected by the first parameter (referred to as first image selection) (step S408). ). When the user selects any of the correction candidate images 213 to 218 using PD 105 (YES in step S408), CPU 106 performs a display process of displaying the selected correction candidate image (step S409). Here, the CPU 106 fixes the first parameter and performs a correction candidate image display process using the second parameter (hereinafter referred to as the first display process), as described later.

  If it is not the first image selection (NO in step S408), the CPU 106 determines whether the correction candidate image is selected by the second parameter (referred to as second image selection) (step S410). When the user selects any of the correction candidate images 223 to 227 using PD 105 (YES in step S410), CPU 106 performs a display process of displaying the selected correction candidate image (step S411). Here, as will be described later, the CPU 106 fixes the second parameter and performs the display processing of the correction candidate image by the first parameter (hereinafter referred to as the second display processing).

  If it is not the second image selection (NO in step S410), the CPU 106 determines whether or not the touch action is the selection of the correction candidate image by both the first and second parameters (step S412).

  In the process (image selection) of step S412, firstly, the user may select a correction candidate image by the other parameter while one parameter is fixed. Secondly, the user may select the correction candidate image displayed in the correction candidate display area 201. Thirdly, the user may select an area in the correction candidate display area 201 where no correction candidate image is displayed.

  If the correction candidate image is selected by the first and second parameters (YES in step S412), that is, if it is one of the first to third, the CPU 106 displays the selected correction candidate image. Display processing is performed (step S413). Hereinafter, this display processing will be referred to as the third display processing.

  If the correction candidate image is not selected by the first and second parameters (NO in step S412), it is determined whether the correction candidate image is determined (step S414). Here, when the OK button 203 is operated with the correction candidate image selected, the CPU 106 determines that the correction candidate image is determined.

  If it is the determination of the correction candidate image (YES in step S414), CPU 106 replaces correction target image 202 with the determined correction candidate image, and ends the selection process. On the other hand, if the correction candidate image is not determined (NO in step S414), the CPU 106 returns to the process of step S403 and waits for the next action by the user.

  Instead of replacing the correction target image 202 with the correction candidate image, the correction candidate image may be saved with a different name and the process may be terminated. Although not described in FIG. 5, when the cancel button 204 is operated, the CPU 106 discards all the processes performed before the operation and ends the selection process.

  FIG. 6 is a flowchart for explaining the first scroll process shown in FIG.

  When the first scroll process is started, the CPU 106 first determines whether or not the first scroll button 211 is operated (step S501). When first scroll button 211 is operated (YES in step S501), CPU 106 performs left scroll processing. Here, the CPU 106 moves the correction candidate images 213 to 218 relating to the first parameter displayed on the display screen 200 to the right by one frame (step S502). As a result, the correction candidate image 218 is hidden. Subsequently, the CPU 106 generates a new correction candidate image with the first parameter and displays it at the position where the correction candidate image 213 has been displayed so far (step S503).

  If it is not the operation of the first scroll button 211 (NO in step S501), the CPU 106 performs the right scroll process assuming that the first scroll button 212 is operated. Here, the CPU 106 moves the correction candidate images 213 to 218 relating to the first parameter displayed on the display screen 200 one frame to the left (step S504). As a result, the correction candidate image 213 is hidden. Subsequently, the CPU 106 generates a new correction candidate image with the first parameter and displays it at the position where the correction candidate image 218 has been displayed so far (step S505).

  After the processing of step S503 or S505, the CPU 106 changes the correction candidate image displayed in the correction candidate display area 201 according to the change of the correction candidate image related to the first parameter (step S506: redisplay). Then, the CPU 106 ends the first scroll process.

  Here, a case where the first scroll process is performed when the display screen 200 is in the initial display state will be described.

  In the initial state, no correction candidate image is displayed in the correction candidate display area 201. Therefore, even if the first scroll process is performed, the CPU 106 does not perform the image generation process for displaying the correction candidate image in the correction candidate display area 201. As a result, at most one correction candidate image is generated with one scroll process, and the CPU 106 can redisplay the display screen 200 at high speed.

  FIG. 7 is a flowchart for explaining the second scroll process shown in FIG.

  When the second scroll process is started, the CPU 106 first determines whether or not the second scroll button 221 has been operated (step S601). When the second scroll button 221 is operated (YES to the step S601), the CPU 106 performs the upward scroll process. Here, the CPU 106 moves the correction candidate images 223 to 227 related to the second parameter displayed on the display screen 200 downward by one frame (step S602). As a result, the correction candidate image 227 is hidden. Subsequently, the CPU 106 generates a new correction candidate image with the second parameter and displays it at the position where the correction candidate image 223 has been displayed so far (step S603).

  If it is not the operation of the second scroll button 221 (NO in step S601), the CPU 106 performs the downward scroll process assuming that the second scroll button 222 is operated. Here, the CPU 106 moves the correction candidate images 223 to 227 related to the second parameter displayed on the display screen 200 upward by one frame (step S604). As a result, the correction candidate image 223 is hidden. Subsequently, the CPU 106 generates a new correction candidate image with the second parameter and displays it at the position where the correction candidate image 227 has been displayed so far (step S605).

  After the processing of step S603 or S605, the CPU 106 changes the correction candidate image displayed in the correction candidate display area 201 according to the change of the correction candidate image related to the second parameter (step S606: redisplay). Then, the CPU 106 ends the second scroll processing.

  When the display screen 200 is in the initial display state, even if the second scrolling process is performed, at most one correction candidate image is generated with one scrolling process as in the first scrolling process. It will only be done. Therefore, the CPU 106 can redisplay the display screen 200 at high speed.

  FIG. 8 is a flowchart for explaining the first display process shown in FIG.

  When the first display process is started, the CPU 106 acquires the first parameter selected by the user (step S701). Here, the CPU 106 acquires the value of the first parameter related to the correction candidate image selected by the operation of the PD 105 among the correction candidate images 213 to 218. Note that the value of this first parameter=n.

  Subsequently, the CPU 106 acquires the value of the second parameter related to the correction candidate image having the smallest value of the second parameter in the correction candidate images 223 to 227 based on the second parameter (step S702). Here, it is assumed that the value of the second parameter related to the correction candidate image 223 is the minimum, and the minimum value=m1.

  Next, the CPU 106 acquires the value of the second parameter related to the correction candidate image having the maximum value of the second parameter in the correction candidate images 223 to 227 based on the second parameter (step S703). Here, it is assumed that the value of the second parameter related to the correction candidate image 227 is the maximum, and the maximum value=m2.

  Subsequently, the CPU 106 sets the increment value of the second parameter, that is, the difference between the maximum value and the minimum value, as the increment value (α) (step S704). Then, the CPU 106 initializes the work variable M related to the second parameter to the minimum value m1 (step S705).

  Next, the CPU 106 determines whether or not the work variable M is less than or equal to the maximum value m2 (step S706). If the work variable M is equal to or less than the maximum value m2 (YES in step S706), the CPU 106 performs a display process of displaying the correction candidate image with the value of the first parameter as n and the value of the second parameter as M. Perform (step S707). Then, the CPU 106 adds the increment value α to the work variable M (step S708), and returns to the process of step S706.

  When work variable M is larger than maximum value m2 (NO in step S706), CPU 106 ends the first display process.

  In this way, when the display process is performed and the user selects the correction candidate image related to the first parameter, only the correction candidate image when the value of the second parameter is changed according to the first parameter is displayed. Will be displayed in the correction candidate display area 201. Note that the display screen 200 shown in FIG. 2B is an example of the display screen 200 when the first parameter is selected. In FIG. 2B, the display screen 200 when the correction candidate image 215 by the first parameter is selected is shown.

  FIG. 9 is a flowchart for explaining the display processing of the correction candidate image shown in FIG. Here, it is assumed that X is designated as the first parameter and Y is designated as the second parameter.

  The CPU 106 refers to the image management table 300 and determines whether or not the image path in which X is specified as the first parameter and Y is specified as the second parameter is stored (step S801). If the image path corresponding to the parameter set (X, Y) is not stored (NO in step S801), the CPU 106 generates a correction candidate image corresponding to the parameter set (step S802). Then, the CPU 106 stores the correction candidate image in the RAM 108 or the like, and registers the image path together with the parameter set in the image management table 300 (step S803).

  Subsequently, the CPU 106 displays the generated correction candidate image in the correction candidate display area 201 at the positions corresponding to the first and second parameters (step S804). Then, the CPU 106 ends the correction candidate image display processing.

  If the image path corresponding to the parameter set (X, Y) is stored (NO in step S801), CPU 106 proceeds to the process of step S804.

  Now, it is assumed that the user operates the scroll button 221 or 222 after the first display process is completed. By this operation, the CPU 106 performs the second scroll process described with reference to FIG. 7. As a result, the correction candidate image displayed in the correction candidate display area 201 is scrolled up or down by one image and displayed.

  As a result, in the correction candidate display area 201, the correction candidate image by the second parameter and the correction candidate image generated by the set of the first parameter and the second parameter designated by the user are displayed. That is, at most two correction candidate images are displayed in the correction candidate display area 201. Therefore, as a result of being able to minimize the generation processing of unnecessary correction candidate images, the display screen 200 can be displayed at high speed.

  In addition, in the scroll processing by the operation of the first scroll button 211 or 212, a new image to be displayed in the correction candidate display area 201 is not generated.

  When the correction candidate image is already registered in the image management table 300, the correction candidate image can be displayed without generating the correction candidate image, as described with reference to FIG. 9. Therefore, it does not take time to generate the correction candidate image.

  FIG. 10 is a flowchart for explaining the second display process shown in FIG.

  When the second display process is started, the CPU 106 acquires the second parameter selected by the user (step S801). Here, the CPU 106 acquires the value of the second parameter related to the correction candidate image selected by the operation of the PD 105 among the correction candidate images 223 to 227. Note that the value of this second parameter=m.

  Subsequently, the CPU 106 acquires the value of the first parameter related to the correction candidate image having the smallest value of the first parameter in the correction candidate images 213 to 218 by the first parameter (step S902). Here, it is assumed that the value of the first parameter related to the correction candidate image 213 is the minimum, and the minimum value=n1.

  Next, the CPU 106 acquires the value of the first parameter related to the correction candidate image having the maximum value of the first parameter in the correction candidate images 213 to 218 by the first parameter (step S903). Here, it is assumed that the value of the first parameter related to the correction candidate image 218 is the maximum, and the maximum value=n2.

  Subsequently, the CPU 106 sets the increment value of the first parameter, that is, the difference between the maximum value and the minimum value, as the increment value (β) (step S904). Then, the CPU 106 initializes the work variable N related to the first parameter to the minimum value n1 (step S905).

  Next, the CPU 106 determines whether or not the work variable N is the maximum value n2 or less (step S906). When the work variable N is equal to or less than the maximum value n2 (YES in step S906), the CPU 106 performs the display process of displaying the correction candidate image with the value of the second parameter as m and the value of the first parameter as N. Perform (step S907). Then, the CPU 106 adds the increment value β to the work variable N (step S908), and returns to the process of step S906.

  When work variable N is larger than maximum value n2 (NO in step S906), CPU 106 ends the second display process.

  When the display process is performed in this way, when the user selects a correction candidate image related to the second parameter, only the correction candidate image when the value of the first parameter is changed according to the second parameter is displayed. It is displayed in the correction candidate display area 201.

  FIG. 11 is a flow chart for explaining the redisplay processing shown in FIG. 7.

  When the redisplay processing is started, the CPU 106 acquires the minimum value n1 and the maximum value n2 of the first parameter in the correction candidate images 213 to 218 by the first parameter (step S1001). Here, it is assumed that the first parameter related to the correction candidate image 213 is the minimum value n1 and the first parameter related to the correction candidate image 218 is the maximum value n2.

  Subsequently, the CPU 106 acquires the minimum value m1 and the maximum value m2 of the second parameter in the correction candidate images 223 to 227 by the second parameter (step S1002). Here, it is assumed that the second parameter related to the correction candidate image 223 is the minimum value m1 and the second parameter related to the correction candidate image 227 is the maximum value m2.

  Next, the CPU 106 sets the increment value of the first parameter, that is, the difference between the maximum value n1 and the minimum value n2, as the increment value (β) (step S1003). Furthermore, in step S1003, the CPU 106 sets the increment value of the second parameter, that is, the difference between the maximum value m1 and the minimum value m2, as the increment value (α). Then, the CPU 106 initializes the work variable N related to the first parameter to the minimum value n1 (step S1104).

  Next, the CPU 106 determines whether or not the work variable N is the maximum value n2 or less (step S1105). When work variable N is larger than maximum value n2 (NO in step S1105), CPU 106 ends the redisplay processing. On the other hand, when the work variable N is equal to or less than the maximum value n2 (YES in step S1105), the CPU 106 initializes the work variable M related to the second parameter to the minimum value m1 (step S1106).

  Subsequently, the CPU 106 determines whether or not the work variable M is equal to or less than the maximum value m2 (step S1107). When work variable M is equal to or smaller than maximum value m2 (YES in step S1107), CPU 106 determines whether work variable N or M is the same as the value of the parameter related to the correction candidate image selected by the user. Is determined (step S1008).

  If they are the same (YES in step S1008), CPU 106 performs display processing on the correction candidate image with the first parameter set to N and the second parameter set to M (step S1009). The display process performed in step S1009 is similar to the display process described in FIG.

  If they are not the same (NO in step S1008), the CPU 106 refers to the image management table 300 and determines whether the image path in which N is registered as the first parameter and M is registered as the second parameter is stored. Yes (step S1010). If the image path is stored (YES to the step S1010), the CPU 106 obtains the image path from the image management table 300, and obtains the correction candidate image having the first parameter N and the second parameter M. It is displayed in the correction candidate display area 201 (step S1011).

  After the processing of step S1009 or S1011, the CPU 106 adds the increment value α of the second parameter to the work variable M (step S1012), and returns to the processing of step S1007. If the image path is not stored (NO in step S1010), CPU 106 advances to the process of step S1012.

  If work variable M is larger than maximum value m2 (NO in step S1107), CPU 106 adds increment value β of the first parameter to work variable N (step S1013), and the process returns to step S1005. .

  FIG. 12 is a flowchart for explaining the third display process shown in FIG. Note that, here, it is assumed that the correction candidate image 235 is selected.

  When the third display process is started, the CPU 106 acquires the value N of the first parameter and the value M of the second parameter regarding the selected correction candidate image 235 (step S1101). Then, the CPU 106 performs display processing on the correction candidate image with the first parameter set to N and the second parameter set to M (step S1102). The display process in step S1102 is similar to the display process described in FIG.

  Subsequently, the CPU 106 obtains the image path corresponding to the set of the corresponding parameters from the image management table 300, and displays the correction candidate image in the correction candidate display area 201 according to the image path (step S1103). At this time, the CPU 106 informs that the correction candidate image is being selected, for example, by displaying the correction candidate image in reverse video.

  Next, the CPU 106 performs a display process on the peripheral correction candidate image (peripheral image) as described later (step S1104). The third display process ends.

  FIG. 13 is a flowchart for explaining the display processing of the peripheral image shown in FIG.

  The CPU 106 acquires the value N of the first parameter and the value M of the second parameter in the selected correction candidate image 235 (step S1201). Then, the minimum value n1 and the maximum value n2 of the first parameter are acquired in the correction candidate images 213 to 218 by the first parameter (step S1202). Here, it is assumed that the first parameter related to the correction candidate image 213 is the minimum value n1 and the first parameter related to the correction candidate image 218 is the maximum value n2.

  Subsequently, the CPU 106 acquires the minimum value m1 and the maximum value m2 of the second parameter in the correction candidate images 223 to 227 by the second parameter (step S1203). Here, it is assumed that the second parameter related to the correction candidate image 223 is the minimum value m1 and the second parameter related to the correction candidate image 227 is the maximum value m2. Next, the CPU 106 sets the increment value of the first parameter, that is, the difference between the maximum value n1 and the minimum value n2, as the increment value (β) (step S1204). Further, in step S1204, CPU 106 sets the increment value of the second parameter, that is, the difference between maximum value m1 and minimum value m2, as the increment value (α).

  Subsequently, the CPU 106 calculates the minimum value Nx of the first parameter and the minimum value Mx of the second parameter used in the peripheral image (step S1205). The peripheral image means a correction candidate image arranged adjacent to the selected correction candidate image (selected image) 235.

  Here, the minimum value Nx is the larger value of the value obtained by subtracting the increment value β from the value N of the first parameter used in the selected image 235 and the minimum value n1 of the first parameter. Here, the value of the first parameter used for the correction candidate image 214 is the minimum value Nx. The minimum value Mx is the larger value of the value obtained by subtracting the increment value α from the value M of the second parameter used for the selected image 235 and the minimum value m1 of the second parameter. Here, the value of the second parameter used for the correction candidate image 224 is the minimum value Mx.

  Subsequently, the CPU 106 calculates the maximum value Ny of the first parameter and the maximum value My of the second parameter used in the peripheral image (step S1206). Here, the maximum value Ny is the larger value of the value obtained by adding the increment value β to the value N of the first parameter used in the selected image 235 and the maximum value n2 of the first parameter. Here, the value of the first parameter used for the correction candidate image 216 is the maximum value Mx. The maximum value My is the larger of the value obtained by adding the increment value α to the value M of the second parameter used for the selected image 235 and the maximum value m2 of the second parameter. Here, the value of the second parameter used for the correction candidate image 226 is the maximum value My.

  Next, the CPU 106 initializes the work variable n of the first parameter to the minimum value Nx (step S1207). Then, the CPU 106 determines whether or not the work variable n is equal to or less than the maximum value Ny (step S1208). When work variable n is larger than maximum value Ny (NO in step S1208), CPU 106 ends the peripheral image display processing. On the other hand, when the work variable n is equal to or less than the maximum value Ny (YES in step S1208), the CPU 106 initializes the work variable m related to the second parameter to the minimum value Mx (step S1209).

  Subsequently, the CPU 106 determines whether or not the work variable m is equal to or less than the maximum value My (step S1210). If work variable m is equal to or smaller than maximum value My (YES in step S1210), CPU 106 determines whether work variable n=first parameter value N and work variable m=second parameter value M. It is determined whether or not (step S1211).

  If n=N and m=M (YES in step S1211), CPU 106 performs display processing on a correction candidate image in which the first parameter is n and the second parameter is m (step S1212). The process of step S1212 is the same as the display process described with reference to FIG.

  After that, the CPU 106 adds the increment value α of the second parameter to the work variable m (step S1213), and returns to the process of step S1210. If n=N and m=M are not satisfied (NO to the step S1211), the CPU 106 proceeds to the process of the step S1213.

  If work variable m is larger than maximum value My (NO in step S1210), CPU 106 adds increment value β of the first parameter to work variable m (step S1214), and the process returns to step S1208. .
