Description

  The present invention relates to an image processing method, an image processing apparatus, an image processing system, and an image processing for performing various image processing while reproducing and displaying a digital image based on original image data sent from a photographing apparatus such as a digital camera. Regarding the program.

  Some digital cameras used for business use output original image data (CCD-RAW data) during shooting. Original image data is unprocessed data output from an imaging device such as a CCD or CMOS incorporated in a digital camera, and is in JPEG (Joint Photographic Coding Expert Group) format output from a digital camera for general users. Compared to image data, the data size is several times larger, but white balance correction and exposure correction can be performed without dropping color information after shooting, so high-quality images are required. Often used for professional photography.

  As it is, the original image data cannot be displayed on the screen of a personal computer (PC) or used for printing an image. Therefore, the original image data output from the digital camera is input to the PC, and can be displayed and printed by an image conversion program installed on the PC, for example, TIFF (Tagged Image File Format) format image data for printing. Then, image conversion processing (generally called development processing) is performed. In this image conversion process, image correction is performed based on conversion parameters such as white balance correction and exposure correction and adjustment parameters such as color tone, gradation, and contrast.

  Some digital cameras that output original image data output reduced JPEG image data (hereinafter referred to as reduced image data) simultaneously with the original image data (see, for example, Non-Patent Document 1).

  For example, in a photo studio, after taking a picture of a customer in a studio using a digital camera that outputs the above original image data, work such as order reception, image verification and image conversion processing, print processing, and delivery is performed. ing.

  In order reception, the original image data obtained by photographing is subjected to image conversion processing, the converted print image data is displayed on the monitor of the order PC, and the customer browses, and the customer selects the image to be printed. Work. In this order reception, in addition to the image to be printed, the number of prints, and the print size, requests for image adjustment such as the trimming range, the orientation of the image, the color tone of the image, and the brightness can be received. After the order is completed, order data is created from the customer information and the order contents.

  In the image verification and image conversion processing, the original image data is converted into print image data based on the conversion parameter and the adjustment parameter in the verification PC, and the conversion parameter and the adjustment parameter are changed while observing the print image data. This is an operation to change and form a higher quality image. The original image data is subjected to image conversion processing every time the conversion parameter and the adjustment parameter are changed, and new print image data is generated. The operator observes the newly generated image data for printing, and repeats the parameter change and the image conversion process until a satisfactory image is obtained. In the printing process, the print image data for which the verification operation has been completed is printed based on the order data. Upon delivery, the completed print photo is given to the customer.

  Since the original image data is composed of pixel data represented by, for example, 12-bit or 16-bit gradation values for each color, the data size is very large and a long time is required for image conversion processing. For this reason, if image conversion processing of a plurality of original image data is performed after completion of photographing, it is not possible to immediately accept an order and it is necessary to have a customer wait.

  Further, in the image verification and image conversion processing, it may take time to perform image conversion processing a plurality of times for one original image data. Furthermore, since the shooting conditions of the studio of the photo studio are stable, the verification work of the original image data shot in the same studio has almost the same contents. However, the conventional image verification is inefficient because an operator has to perform verification for each image data.

  Further, since the original image data has a large data size, it takes time to transfer the original image data from the digital camera to the ordering PC and the verification PC, and photographing cannot be performed during the transfer. In particular, since not all the original image data transferred to the ordering PC is ordered, the transfer is often wasted.

  The present invention has been made in view of the above circumstances, an image processing method, apparatus, and system that can perform order reception and image verification immediately after shooting, and do not transfer unnecessary original image data. And to provide a program.

  The image processing method of the present invention uses reduced image data generated together with original image data for order reception. Further, the reduced image data is also used for image verification, and image conversion processing is performed on the original image data based on the image verification result for the reduced image data. Further, when an image adjustment for an image is ordered at the time of order reception, the adjustment content is reflected in the image adjustment processing of the reduced image data. In addition, a preset parameter is used without adjusting the conversion parameter used for the image conversion process. Furthermore, only the original image data for which a print order has been placed is read from the photographing apparatus.

  The image processing apparatus according to the present invention includes an image input unit that inputs original image data and reduced image data, a reduced image reproduction display unit that reproduces and displays an image of the reduced image data, and an image of the displayed reduced image data. An order means for receiving an order for an image to be printed, an order data generation means for generating order data based on the order contents of the print, and a standard adjustment parameter for reduced image data corresponding to the image for which the print order has been received Reduced image data adjustment means for performing image adjustment processing, parameter adjustment means for adjusting the standard adjustment parameters to generate change adjustment parameters, and change adjustment parameters for original image data corresponding to an image for which a print order has been received, And / or image conversion processing based on preset conversion parameters to generate print image data. And a printing image data generating means for.

  Further, the order means accepts an order for image adjustment for the reduced image data, the adjustment data is generated by the order data generation means based on the contents of the order, and the reduced image data is generated based on the adjustment data and the change adjustment parameter. The adjustment means performs image adjustment processing on the reduced image data.

  An image processing system according to the present invention includes a photographing device that generates original image data of a photographed subject and reduced image data obtained by reducing the original image data, and the above-described image processing device. The original image data was transferred only to the print order.

  Further, in order to realize each means constituting the image processing apparatus, the image processing apparatus is configured by an image processing program that causes a computer apparatus to function.

  According to the present invention, it is possible to accept an order with reduced image data immediately after the photographing is completed, so that the customer does not have to wait after photographing at a photo studio or the like. In addition, since only the image adjustment verification is performed based on the reduced image data, the image verification can be performed immediately after shooting without waiting for a time-consuming image conversion process.

  Further, since the adjustment data can be reflected in the image adjustment processing of the reduced image data for the image for which the order has been received, it is possible to reliably incorporate the customer's request. Furthermore, since only the original image data for which a print order has been received is input from the photographing apparatus to the image processing apparatus, useless data transfer time can be reduced.

  FIG. 1 is a block diagram showing a configuration of an image processing system embodying the present invention. This image processing system is used in, for example, a photo studio. The configuration is for controlling the digital camera 2 used for photographing a customer in the studio and controlling the digital camera 2 and storing image data generated by the digital camera 2 and transferring it to another PC. Using the PC 3 and the image data transferred from the camera control PC 3, an order PC 4 for receiving a print order from a customer, and an image verification for verifying that the received image data has higher image quality The PC 5 includes an image conversion PC 6 that generates image data for printing, and a printer 7 that creates a print based on the image data for printing.

  FIG. 2 is a block diagram showing the configuration of the digital camera 2 and the camera control PC 3. Each unit of the digital camera 2 is connected to each other via the data bus 10 and its operation is controlled by the CPU 11 as a whole. A program for operating the digital camera 2 is recorded in the ROM 12. The imaging unit 14 includes a known photographic lens, a CCD, and the like, and generates digital image data by photoelectrically converting an optical image of a subject.

  Shooting conditions such as aperture and shutter speed are set by operating various setting buttons provided on the operation unit 18 while confirming an operation menu displayed on the LCD 17. The LCD 17 is used as a viewfinder in the shooting mode, and is used for playback display of image data in the playback mode.

  The image data output from the imaging unit 14 is buffered in the RAM 13. This image data is original image data (CCD-RAW data) that has not been subjected to image correction such as white balance processing, and a large number of pixel data having gradation values represented by 12 bits or 16 bits for each color. Consists of

  The image processing circuit 21 performs white balance (WB) processing, gradation conversion processing, and the like under conditions set in advance for each model, and outputs image data after image correction. The compression / decompression processing circuit 22 compresses the image data after image correction in accordance with a format defined by JPEG to generate JPEG image data.

  The digital camera 2 can select the type of image data to be output. For example, only original image data can be output, or only JPEG image data can be output. Also, original image data and reduced image data (JPEG data, bitmap data, etc.) can be output simultaneously. When these two types of image data are output simultaneously, the original image data is converted into reduced image data, and further thinned out as necessary, for example, about 1280 × 960 pixels.

  As shown in FIG. 3, the original image data and the reduced image data are stored in an image folder 27 formed in the recording medium 26 by the media controller 25. The same file names with different extensions are assigned to the original image data and the reduced image data output simultaneously, for example, “DSC0001.raf” and “DSC0001.jpg”. Therefore, by confirming the file name, the relationship can be understood.

  The digital camera 2 and the camera control PC 3 are connected by a communication cable 30 between their input / output I / Fs 28 and 29. With this connection, original image data and reduced image data, and shooting control data generated when shooting conditions of the digital camera 2 are set by the camera control PC 3 are transmitted and received between the digital camera 2 and the camera control PC 3. . As the input / output I / Fs 28 and 29, for example, those conforming to USB (Universal Serial Bus) or IEEE1394 are used. Note that, instead of the communication cable 30, data communication may be performed using wireless communication means.

  The original image data and the reduced image data recorded in the recording medium 26 are transmitted from the digital camera 2 to the camera control PC 3 by an operation on the digital camera 2 or the camera control PC 3. Therefore, even when the recording capacity of the recording medium 26 of the digital camera 2 is small, continuous shooting can be performed. As will be described in detail later, the original image data and the reduced image data generated by the digital camera 2 are not recorded on the recording medium 26 according to the settings of the camera control program installed in the camera control PC 3, and the camera control is performed. It can also be transferred directly to the PC 3.

  For example, a commercially available personal computer is used for the camera control PC 3, and an external storage device 33 formed of a hard disk drive or the like includes a digital camera together with an operating system (OS) that controls the operation of the camera control PC 3. A camera control program used for control 2 is installed.

  When the camera control PC 3 is powered on, the OS stored in the external storage device 33 is loaded into the RAM 36 and the camera control PC 3 is activated. Further, when the camera control program is executed by operating the keyboard 37 or the mouse 38, the camera control program is similarly loaded into the RAM 36 and executed.

  The camera control PC 3 and the camera control program reproduce and display the image of the reduced image data transmitted from the digital camera 2 on the monitor 41, and respond to operation signals from input devices such as the keyboard 37 and the mouse 38, Various settings and control of the digital camera 2 are performed. The units of the camera control PC 3 are connected to each other via a data bus 42, and the operation of the CPU 43 is generally controlled by the CPU 43. Original image data and reduced image data sent from the digital camera 2 are recorded in the external storage device 33 via the input / output I / F 29 and the data bus 42.

  For example, the camera control program controls the digital camera 2 with the camera control PC 3 to set the shooting conditions, release the shutter, etc., and store the image data in the camera control PC 3. Standard camera control mode for setting shooting conditions, shutter release, etc., and storing image data in the recording medium 26, setting of shooting conditions, shutter release, etc. with the digital camera 2, and storage of image data in the PC 3 for camera control It has an extended camera control mode.

  The camera control PC 3 is connected to a local area network (LAN) by a built-in network adapter 45. As the order PC 4, the image verification PC 5, and the image conversion PC 6, a commercially available personal computer is used similarly to the camera control PC 3, and is also connected to the LAN by a network adapter. The camera control program transfers the reduced image data transmitted from the digital camera 3 to the ordering PC 4 and the image verification PC 5. Further, the original image data corresponding to the image for which the print order has been received by the order PC 4 is transferred to the image conversion PC 6. Note that the configuration of each of the PCs 4 to 6 is substantially the same as that of the camera control PC 3, and therefore the description of the configuration is omitted below.

  The external storage device of the ordering PC 4 is installed with an ordering program for browsing a photographed image and selecting an order for printing together with a customer. As shown in FIGS. 4 and 5, the order program is selected on the print order screen 48 that displays a list of a plurality of reduced image data input from the camera control PC 3 on the monitor and the print order screen 48. An image adjustment screen 50 for enlarging and displaying the reduced image data is displayed. Operations on these screens are performed using a mouse or a keyboard.

  One of the print order screen 48 and the image adjustment screen 50 is selectively displayed on the monitor by a switching operation. This switching operation switches from the print order screen 48 to the image adjustment screen 50 when the “image adjustment” button 53 arranged on the upper right of the print order screen 48 is clicked with the mouse. Similarly, when the “print order” button 54 arranged on the upper right of the image adjustment screen 50 is clicked with the mouse, the image adjustment screen 50 is switched to the print order screen 48.

  The print order screen 48 includes a basic data display frame 57, an image display frame 58 for displaying images of a plurality of reduced image data, a print designation frame 59, and a print fee display frame 60. The basic data display frame 57 displays the reception date and time, the print finish date and the like, together with the customer name and contact information, the user ID number and the reception number. The customer's name, contact information, user ID number, etc. are newly entered for the first customer, and read from the customer database stored in the ordering PC 4 for customers who have used in the past. It is.

  In the image display frame 58, images 63 to 66 of a plurality of reduced image data input from the camera control PC 3 are displayed. At the upper part of each image 63-66, there are provided file name display parts 63a-66a for displaying the file name before the extension of the reduced image data of the image. Also, at the bottom of each image 63 to 66, there are provided number display sections 63b to 66b and size display sections 63c to 66c for displaying the number of prints ordered and the print size.

  When a print order is made for each image, the image, for example, image 65, is clicked and selected with the mouse. As a result, the density of the frame around the selected image 65 is displayed dark, so that the currently selected image can be easily identified. Note that by operating a scroll bar 69 disposed between the image display frame 58 and the print designation frame 59, the image display frame 58 can be scroll-displayed, and four or more images can be viewed. .

  In the print designation frame 59, for example, a size selection area 59a for selecting a print size from all sheets to eight cuts and a number selection area 59b for specifying the number of prints are provided. In the upper part, a file name display part 59c for displaying the file name of the currently selected image is provided. The print fee display frame 60 displays a list of designated print sizes and the number of prints, and a print fee automatically calculated according to the list.

  When a predetermined image is double-clicked in the image display frame 58 or an image is selected in the image display frame 58 and the “image adjustment” button 53 is clicked, the image adjustment screen 50 shown in FIG. 4 is displayed. The image adjustment screen 50 includes an enlarged display frame 72 in which a selected image, for example, an image 65 is enlarged, a title bar 73 that displays the file name of the image displayed in the enlarged display frame 72, and an image adjustment frame 74. It consists of.

  The image adjustment frame 74 is provided with a large number of adjustment units 77a to 77e for changing various adjustment items such as color balance, brightness, and contrast. The values of the adjustment units 77a to 77e can be adjusted by directly inputting numerical values into the input box 78 or by moving the indicator 79 left and right in the drawing. The ordering program performs image adjustment on the reduced image data of the image 65 based on the image adjustment performed by the adjusting units 77a to 77e, and the enlarged display unit 72 displays the image 65 of the reduced image data thus adjusted. Playback display. Thereby, image adjustment can be performed while confirming the adjustment result together with the customer.

  A trimming frame 82 is displayed on the image 65 of the enlarged display portion 72. The print range can be specified by changing the size of the trimming frame 82 with the mouse. The aspect ratio of the trimming frame 82 may be changed according to the aspect ratio of the print size selected on the print order screen 48 described above, or may be changed freely.

  At the end of the order by the customer, an end button 85 arranged at the bottom of the print order screen 48 is clicked. Then, as shown in FIG. 6, order data 88 is generated from the customer information, the file name of the ordered image, the number of prints and the print size of each image. In addition, adjustment data 89 is generated from image adjustment information and trimming information performed on each image. These order data 88 and adjustment data 89 are stored in a newly created order folder 90 and transmitted to the image verification PC 5. The order data 88 is also used for updating the customer database stored in the ordering PC 4.

  Further, the order data 88 is also transmitted to the camera control PC 3. Upon receiving the order data 88, the camera control PC 3 transmits only the original image data corresponding to the reduced image data designated for printing to the image conversion PC 6. As a result, the amount of LAN data transfer in the photo hall is reduced, so that the processing load on each PC for data transfer can be reduced. The original image data that has not been ordered may be deleted from the camera control PC 3 at this time.

  A test program for testing reduced image data input from the camera control PC 3 is installed in the external storage device of the image test PC 5. This test program is used for adjustment of conversion parameters used for image conversion processing for converting original image data into image data for printing, and adjustment parameters used for image adjustment processing of image data for printing.

  As shown in FIG. 7, on the operation screen 92 of the test program displayed on the monitor, a test target image display area 94 for displaying the image 93 of the reduced image data to be tested, and a reduction for displaying a plurality of reduced images side by side. An image display area 95 and a parameter adjustment area 96 are provided. On the upper side of the test target image display area 94, a title bar 97 on which the title (file name) of the test target image 93 is displayed is displayed.

  The image verification program performs image adjustment processing on predetermined reduced image data input from the camera control PC 3 based on adjustment data 89 and preset standard adjustment parameters 98. As a result, the reduced image data used for the verification reflects the customer's opinion, so that the verification operation that satisfies the customer can be performed. The reduced image data subjected to the image adjustment processing is displayed in the reduced image display area 95 as reduced images 100 to 103. The image selected in the reduced image display area 95 is displayed in the test object image display area 94 as the test object image 93.

  In the example shown in the figure, four frames of reduced images are displayed in the reduced image display area 95, but the number of frames to be displayed simultaneously can be increased or decreased as appropriate. Further, the selection cursor 104 is highlighted around the reduced image 102 corresponding to the test target image 93, and the test target image 93 and the reduced image 102 are associated with each other. On the right side of the reduced image display area 95, a scroll bar 105 that can be scrolled up and down is provided. When there are five or more reduced images, the fifth and subsequent reduced images can be displayed by sliding the scroll bar 105 up and down.

  Among the plurality of reduced images 100 to 103 displayed in the reduced image display area 95, those for which the verification operation has not been completed (reduced images 102 and 103 for the two frames on the right side in the example in the figure) are displayed in black and white. Yes. In contrast, for a reduced image that has been verified (for example, the second reduced image 101 from the left end) or a reduced image that has not been ordered for printing (for example, the leftmost reduced image 100), full color Is displayed.

  The parameter adjustment area 96 is provided with two types of change screens of “image adjustment” for changing the standard adjustment parameter 98 and “conversion condition” for changing the conversion parameter. By selecting, it is possible to switch to each change screen. When the “image adjustment” tab is selected, an image adjustment screen 109 is displayed in the parameter adjustment area 96.

  The image adjustment screen 109 is provided with a large number of adjustment units 110a to 110e that change standard adjustment parameters 98 such as color balance, brightness, and contrast. The values of the adjusting units 110a to 110e are adjusted by directly inputting numerical values in the input box 111 or by moving the indicator 112 to the left and right in the figure, as in the ordering program of the ordering PC 4. be able to. When each of the adjustment units 110a to 110e is adjusted, the standard adjustment parameter 98 is changed. Based on the changed standard adjustment parameter 98, image adjustment processing is performed on the reduced image data corresponding to the test target image 93. Is done. As a result, the test target image 93 whose image has been adjusted is always displayed in the test target image display area 94.

  Various adjustments are made while confirming the test target image 93, and after the adjustment contents are determined, the “OK” button 115 is operated. Then, a change adjustment parameter representing the adjustment contents made by this verification work is generated. As shown in FIG. 6, the change adjustment parameter 117 is stored in the order folder 90 as a data file. The order folder 90 is transmitted to the image conversion PC 6 after the verification of all print designated images is completed.

  In the image processing system of this embodiment, adjustment of conversion parameters is not performed by the image verification PC 5 during normal operation. This is because, in a typical photo studio, there is no significant change in the shooting environment. Therefore, in the image conversion PC 6 described below, rather than adjusting the conversion parameters of all image data in the image verification PC 5, This is because using the conversion parameters optimized for the photography environment of the studio in the photo studio improves the examination efficiency.

  The external storage device of the image conversion PC 6 is installed with an image conversion program for performing image conversion processing on the original image data input from the camera control PC 3 and generating print image data. The image data for printing is composed of image data of, for example, TIFF format that can be displayed on a PC and printed by a printer, and is converted from the original image data while maintaining the resolution.

  In the image conversion PC 6, the conversion parameter 120 used at the time of image conversion processing is set in advance according to the shooting environment of the studio of the photo studio. The conversion parameter 120 is stored in the external storage device of the image conversion PC 6 and is read and used during image conversion processing. As described above, by using the conversion parameter 120 specified for the studio with a small change in the shooting environment, the adjustment of the conversion parameter 120 in the verification work can be omitted, so that the efficiency of the verification work can be improved. .

  The image conversion PC 6 specifies original image data to be printed based on the order data 88 input from the image verification PC 5, and performs image conversion processing on the original image data based on the change adjustment parameter 117 and the conversion parameter 120. Apply. Note that the image conversion processing in the image conversion PC 6 can be automated because it requires no operator work.

  The print image data generated by the image conversion process is stored in the order folder 90 with the file name as it is and the extension is converted to “tif”. As a result, since all data generated by photographing of a specific customer is stored in the order folder 90, it is possible to easily cope with an order such as extra printing. The image data for printing is output from the image conversion PC 6 to the printer 7, and the ordered number of sheets is printed at the size of the order received.

  Next, the processing procedure of the image processing system of the present invention will be described using the flowchart shown in FIG. The digital camera 2 or the camera control PC 3 is operated to set shooting conditions for the digital camera 2 (S1). Based on the set shooting conditions, a customer is shot by the digital camera 2 in the studio, and original image data and reduced image data are generated (S2). The original image data and the reduced image data are stored in the external storage device 33 of the camera control PC 3 by the input / output I / Fs 28 and 29 and the communication cable 30 (S3). When the original image data and the reduced image data are stored in the recording medium 26, they are transmitted to the external storage device 33 by the subsequent operation of the digital camera 2 or the camera control PC 3.

  The camera control PC 3 transmits the reduced image data to the order PC 4 and the image verification PC 5 (S4). The ordering PC 4 accepts an order for an image to be printed from a customer using a print order screen 48 of the ordering program shown in FIG. Further, the image adjustment screen 50 shown in FIG. 5 is used to perform image adjustment desired by the customer (S5). By this order, order data 88 and adjustment data 89 are generated, stored in the order folder 90, and transmitted to the image verification PC 5 (S6). Thus, since the reduced image data is used for the customer's order selection, it is possible to accept the order immediately after the photographing is completed without waiting for the image conversion process. In addition, image adjustment can be performed based on a customer's request when an order is received.

  The order data 88 is also transmitted to the camera control PC 3. The camera control PC 3 transmits the original image data corresponding to the image ordered for printing to the image conversion PC 6 (S7). As described above, only the original image data for which print order has been placed is transmitted from the camera control PC 3 to the image conversion PC 6, so that unnecessary load of original image data having a large data size causes load on each PC due to data transfer. Will not occur.

  The image verification PC 5 performs image adjustment processing on the reduced image data based on the adjustment data 89 transmitted from the order PC 4 and the standard adjustment parameter 98 set in advance, and the image of the reduced image data after the adjustment is obtained. A list is displayed in the reduced image display area 95 (S8). As a result, an image test reflecting the customer's request can be performed. Since the reduced images displayed in the reduced image display area 95 are displayed in black and white except for those that have already been verified or excluded from the verification target, it is possible to easily identify the images that need to be verified.

  The image selected by the operator in the reduced image display area 95 is displayed large in the test object image display area 94 as the test object image 93. The operator operates the adjustment units 110a to 110e on the image adjustment screen 109 to adjust the standard adjustment parameter 98 of the test target image 93 (S9). As a result, the image adjustment process is performed on the reduced image data corresponding to the verification target image 93 based on the changed standard adjustment parameter 98, and the adjusted image is updated and displayed in the verification target image display area 94. . The image adjustment is finished when an image having a finish desired by the operator is obtained. When the image adjustment is completed and the “OK” button 115 is operated, a change adjustment parameter 117 representing the content of the image adjustment is generated, stored in the order folder 90, and transmitted to the image conversion PC 6 (S10).

  The image conversion PC 6 specifies original image data to be printed based on the order data 88, and performs image conversion processing on the original image data based on the change adjustment parameter 117 and the conversion parameter 120 (S11). The print image data generated by the image conversion process is stored in the order folder 90. The image data for printing is output from the image conversion PC 6 to the printer 7, and the order number of sheets is printed at the size of the order received (S12). The completed print is delivered to the customer along with a delivery note (S13).

  As described above, since the conversion parameter set in advance according to the shooting environment of the studio is used, adjustment of the conversion parameter can be omitted, and the efficiency of the verification work can be improved. In addition, since the conversion parameter is not adjusted, the reduced image data can be used for the verification operation, so that the verification operation can be performed immediately after the photographing is completed. Further, since it is not necessary to perform image conversion processing at the time of verification, the verification work time can be shortened.

  In the above embodiment, the image conversion PC 6 performs the image conversion process on the original image data using the conversion parameter 120 set in advance. However, in the studio of a photo studio, when the number of photographers increases or decreases with respect to the number of photographers assumed as a standard, the lighting environment has to be changed, so that the photographing environment changes greatly. In such a case, in the image conversion process using the preset conversion parameter 120, white balance and exposure correction cannot be performed appropriately. Therefore, the verification PC 5 reads the target original image data from the camera control PC 3. Therefore, it is necessary to adjust the conversion parameters by the image verification program.

  In FIG. 7, when the “Conversion Condition” tab 125 is selected, a conversion condition change screen 126 is displayed as shown in FIG. On the conversion condition change screen 126, for example, a tone curve correction unit 127 that corrects a tone curve, a white balance correction unit 128 that corrects a light source and a color temperature, an exposure correction box 129, and an sensitization correction box 130 are displayed. By operating, each conversion parameter can be changed.

  The conversion parameters are not limited to the tone curve and white balance parameters shown in FIG. 9, and may include, for example, a sharpness correction parameter. In addition to the parameters shown in FIG. 7, for example, trimming correction parameters can be included as adjustment parameters. Furthermore, combinations of conversion parameters and adjustment parameters are not limited to those listed in the present embodiment, and the combinations can be determined as appropriate. For example, a color balance correction parameter may be included as a conversion parameter.
