[Prior art]
An image reproduced by a printer device such as a film or photo is read by a scanner or the like and provided to the user as digital image data, or the digital image data obtained by the user using a digital camera or the like is printed out and provided to the user To be done. Such image data can be displayed and observed by a user on a monitor such as a personal computer. For this reason, the color space of the image data is the sRGB color space so that it looks best when displayed on the monitor. The Exif standard, which is a standard for digital cameras, assumes that the color space of image data is limited to sRGB.
[0003]
By the way, depending on the model of the digital camera, there is provided one capable of recording image data in the Adobe (registered trademark) RGB color space, which has a wider color reproduction range than sRGB. By adopting the AdobeRGB color space in this way, it is possible to deal with applications that require a wide color gamut such as printing.
[0004]
An image processing method for converting an image color space to another color space has been proposed (see Patent Document 1). According to the method of Patent Document 1, for example, when an image in the sRGB color space is displayed on a monitor dedicated to Adobe RGB, the color reproducibility of the reproduced image is appropriately changed by converting the color space of the image from sRGB to Adobe RGB. Can be.

[0037]
The CPU 12 causes the computer 1 to function as the image display device according to the present embodiment by executing the image viewer program recorded in the ROM 13. That is, when an instruction to start the image viewer is given from the input unit 16, a list of thumbnail images of the image data stored in the storage unit 11 is displayed on the monitor 15. At this time, referring to the color space parameter 34 of the tag information 21 of the image data, the color space identification name of the image is given to the thumbnail image. When the color space is unknown, “unknown” is displayed as the color space identification name, and the input from the color space name input means 16 for the unknown color space is received, and the input color space The name is described in the tag information 21 of the image data as a new color space parameter.
[0038]
Next, processing performed in the present embodiment will be described. FIG. 6 is a flowchart showing processing performed in the present embodiment. When the user gives an instruction to start the image viewer, the CPU 12 executes a program recorded in the ROM 13 to start processing. First, the CPU 12 sets m = 1 as an initial value (step S1), and sequentially reads image data from the 001 folder of the storage unit 11 (step S2).
[0039]
Then, with reference to the color space parameter 34 of the tag information 21 of the read image data, it is determined whether or not the color space name included in the color space parameter 34 is included in the color space table T 1 stored in the storage unit 11. (Step S3). If step S3 is affirmed, the color space identification name corresponding to the color space name is displayed on the monitor 15 together with the thumbnail image of the image data (step S4).
[0040]
If step S3 is negative, it is determined whether or not the color space name is unknown because the color space name is not assigned to the color space name described in the color space parameter 34 (step S5). If step S5 is affirmed, “unknown” is displayed on the monitor 15 together with the thumbnail image of the image data as the color space identification name (step S6).
[0041]
If step S5 is negative, is there a match in the color space table T1 regarding the white point, primary color chromaticity coordinates, YCC to RGB conversion coefficient, and reproduction gamma of the color space parameter 34 of the image data? It is determined whether or not (step S7). If step S7 is affirmed, the CPU 12 refers to the color space table T1 and converts the color space name of the color space parameter 34 of the image data from the matched white point, primary color chromaticity coordinates, YCC to RGB. The color space name for the coefficient and reproduction gamma is rewritten (step S8), and the color space identification name corresponding to the rewritten color space name is displayed on the monitor 15 together with the thumbnail image of the image data (step S9).
[0042]
If step S7 is negative, the color space parameter 34 of the image data is registered in the color space table T1 (step S10), and the color space name included in the color space parameter 34 of the image data is used as the color space identification name. The thumbnail image is displayed on the monitor 15 (step S11).
[0043]
Subsequently, the CPU 12 determines whether or not the display of the thumbnail images of all the image data stored in the 001 folder of the storage unit 11 has been completed (step S12), and ends the process when step S12 is affirmed. To do. If step S12 is negative, m = m + 1 is set to display the next image data (step S13), the process returns to step S2, and the processes after step S2 are repeated until step S12 is positive.
[0044]

As shown in FIG. 7, the monitor 15 displays a list 41 of thumbnail images, a pull-down menu 42 for selecting a color space to be displayed, and a scroll bar 43. Each thumbnail image included in the thumbnail image list 41 has a color space identification name such as sRGB or Adobe displayed in the upper right corner and a file name displayed below. Note that “unknown” is displayed as the color space identification name for thumbnail images of image data for which the color space name is unknown and the color space parameter is not in the color space table T1. The scroll bar 43 can scroll the thumbnail image list 41.
[0045]
Here, a color space name can be input by, for example, double-clicking the display part of “unknown”. FIG. 8 is a flowchart showing processing when inputting a color space name. The CPU 12 starts processing by double-clicking on the display of “Unknown”, and determines whether or not a color space name has been input (step S21). If step S21 is affirmed, the input color space name is displayed (step S22), and further input to the color space name of the color space parameter 34 of the tag information 21 of the image data stored in the storage unit 11. The color space name is described (step S23). Further, the color space parameter assigned to the image data is registered in the color space table T1 together with the input color space name (step S24), and the process is terminated.
[0046]
As a result, the file name for which “unknown” is displayed in the thumbnail image list shown in FIG. In the JPG thumbnail image, as shown in FIG. 9, the input color space name (for example, User1 defined by the user) is displayed as the color space identification name.
