Description

  The present invention relates to color management.

  In general, it is an important issue for a company dealing with Internet shopping to faithfully reproduce the color of a product on a screen display device such as a personal computer or a mobile phone used for this shopping. If the color of the product displayed on the screen display device is far from the actual color, it is difficult to sell this product on the Internet.

  By the way, the following two methods are generally used for color management used for faithfully reproducing colors in a screen display device.

  In the first method, the color of the screen is measured with a colorimeter, color correction data called a profile (hereinafter referred to as color correction data) is created, and based on this color correction data, This is to correct the screen color.

  In the second method, the color of the screen is compared with the object without a colorimeter, color correction data is created, and the screen color is color-corrected based on the color correction data.

  However, some screen display devices, such as mobile phones, cannot retain color correction data and apply it to screen color correction. In consideration of individual differences in screen display devices, differences in use environment, etc., it is meaningless to apply uniform color correction data to the color correction of the screen curler of each screen display device.

  Accordingly, it is difficult to say that current mobile phones can faithfully reproduce colors.

  The present invention has been made in view of such background art, and is a screen display device that retains color correction data and cannot apply the color correction data to color correction of a screen color like a mobile phone. The challenge is to faithfully reproduce colors.

In order to achieve the above object in the present invention, first, the invention of claim 1 is a system connected to each screen display device via the Internet,
By displaying a screen correction image on each screen display device, and allowing the user to visually correct the color of the screen correction image to match the color of the screen correction image printed on the color sheet, A function to create color correction data for each screen display device,
A function to store the color correction data of each screen display device created,
Each image display device receives image data to each image display device from each Web site, and performs color correction on the image data to each image display device based on the color correction data of each screen display device. A color management system characterized by having a display function.

The invention of claim 2 is a method executed by a system connected to each screen display device via the Internet,
By displaying a screen correction image on each screen display device, and allowing the user to visually correct the color of the screen correction image to match the color of the screen correction image printed on the color sheet, Creating color correction data for each screen display device;
A process of storing the color correction data of each screen display device created,
Each image display device receives image data to each image display device from each Web site, and performs color correction on the image data to each image display device based on the color correction data of each screen display device. A color management method characterized by including a display step.

  The present invention holds color correction data like a mobile phone, and can reproduce colors faithfully even on a screen display device that cannot apply the color correction data to screen color correction. effective.

The best embodiment of the present invention will be described below.
1. Configuration As shown in FIG. 1, one or a plurality of screen display devices, one or a plurality of Web sites, and the color management system of the present invention are connected to the Internet. Hereinafter, it is assumed that the screen display device and the Web site are respectively connected to the Internet.

  The screen display device has a Web browser, and the user can use each Web site by using the Web browser on the screen display device.

  As shown in FIG. 1, the color management system of the present invention includes at least a Web server and a database.

  The Web server is a screen display device for allowing a user to use a color management system using a Web browser.

  The database is for storing color correction data of each screen display device.

  The color management system of the present invention is a computer system having the following functions (1) to (3).

  (1) A screen correction image is displayed on each screen display device, and the user visually corrects the color of the screen correction image to match the color of the screen correction image printed on the color sheet. A function to create color correction data for each screen display device.

  (2) A function for storing the color correction data of each created screen display device.

  (3) Image data to each image display device is received from each website, and the image data to each image display device is subjected to color correction based on the color correction data of each screen display device. Function to display on image display equipment.

The color sheet has a screen correction image printed as described above, and is distributed in advance to each user. FIG. 2 shows an example of a color sheet. A color bar is printed as the screen correction image 2 on the color sheet 1 shown in FIG.
2. Processing An example of the flow of color management processing performed by the color management system of the present invention will be described below with reference to the flowchart of FIG.
S (STEP) 1;
The user inputs the URL of the color management system using a Web browser on the screen display device, and connects the screen display device to the color management system.

FIG. 4 shows an example of a screen for inputting a URL. In the screen of FIG. 4, when the URL of the color management system is input and the connection button is pressed, the screen display device connects to the color management system.
S (STEP) 2;
The color management system displays a screen correction image on the screen display device, and allows the user to visually correct the color of the screen correction image to match the color of the screen correction image printed on the color sheet. . At this time, it is desirable to correct the screen display device under a light source that is normally used.

FIG. 5 and FIG. 6 show examples of screens that allow the user to perform color correction visually. In the screen of FIG. 5, the color correction is performed by adjusting the RGB color balance with the slide bar so that the color of the screen correction image 3 matches the color of the screen correction image 2 of the color sheet shown in FIG. Do. In the screen of FIG. 5, when the reset button is pressed, the position of the slide bar returns to before adjustment. In the screen of FIG. 6, the color correction is performed by adjusting the RGB color balance by numerical input so that the color of the screen correction image 4 matches the color of the screen correction image 2 of the color sheet shown in FIG. I do.
S (STEP) 3;
The user transmits the content of the color correction to the color management system using the screen display device.

In the example of the screen of FIG. 5 or FIG. 6, when the enter button is pressed, the content of color correction is transmitted to the color management system.
S (STEP) 4;
The color management system receives the color correction content transmitted from the screen display device, and creates color correction data of the screen display device from the color correction content.
S (STEP) 5;
The color management system stores the created color correction data in a database. S (STEP) 6;
When a user uses a website on a screen display device via a color management system, the color management system receives image data from the website to the image display device and displays the image data on the screen display. After performing color correction based on the color correction data of the device, the image is displayed on the image display device.

The figure which shows the structural example of the system concerning this embodiment. The figure which shows the example of a color sheet. 6 is a flowchart showing an example of the flow of color management processing. The figure which shows the example of the screen which inputs URL. The figure which shows the example of the screen which makes a user correct | amend color visually. The figure which shows the example of the screen which makes a user correct | amend color visually.
