Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a general computer system using a color correction system.

Reference numerals 10 and 20 denote clients, each of which has an information processing device having the same Internet connection function as a conventional one, for example, a personal computer. The personal computer is equipped with a browser for displaying a markup language document. The client 10 is a client used by a color blind person,
Reference numeral 20 denotes a client used by healthy persons.

Reference numeral 30 denotes a communication line for the Internet. The present invention is not limited to the Internet,
And wireless communication, and other communication lines.

Reference numeral 40 denotes a conversion server, which returns the description contents of a markup language document provided from a Web server 50 described later based on a color conversion table (color correction contents of the present invention) registered for each user in advance. . More specifically, the color component in the instruction regarding the display color in the markup language document is changed to the color component described in the color conversion table.

Reference numeral 50 denotes a WEB server which stores a markup language document to be provided to the clients 10 and 20 in a built-in storage device. The WEB server 50 communicates with the browser of the client and delivers a markup language document, a markup language document for inspecting the degree of color vision according to the present invention, and a Web server 50 created from the result of the inspection. The conversion table stored in the storage device inside / outside the WEB server 50 or a program for reading out and transferring the conversion table to the conversion server 40 is stored.

In this embodiment, the conversion server 40 and W
The EB server 50 forms a color correction system.

The operation of such a system will be described with reference to the flowchart of FIG. The flowchart of FIG. 2 shows the processing content of the color correction system.

(User Registration) The color vision impaired person uses the browser of the client 10 to read and display the markup language document for color vision inspection on the WEB server 50. Generally, by inputting storage address information (also called a communication address) called a URL from a keyboard, a markup language document for color vision inspection is displayed on a display screen of a client. The color vision inspection markup language document is, for example, a document for displaying a color vision inspection table used in a medical institution.

The WEB server 50, which has received the request for the document from the browser of the client 10 via the conversion server 40, reads out from the internal storage device and provides it to the client 10 (S10 → S11). As a result, a markup language document for color vision inspection is displayed on the display screen of the client 10, and the person with color vision impairment is asked a question specified and displayed in the markup language document.
For example, a question as to how the displayed image looks is answered from among the displayed answer candidates. The answer is input by the keyboard or the mouse of the client 10 (S12).

The response result input to the client 10 is sent to the WEB server 50 based on a command specified in the markup language document. WEB server 5
At 0, a color conversion table suitable for the color-blind person who made the answer is created according to the color-blindness indicated by the input answer result. For this purpose, a plurality of types of color conversion tables corresponding to the contents of the answers may be prepared, and a color conversion table corresponding to the answer result of the color vision impairment may be selected. Changes in the description of the color conversion table and general markup language documents will be described later.

The created (selected) conversion table is registered in the internal storage device in association with the color-blind person or the color-blind person who input the answer (S13).

For example, when the information provided by the web server 50 is provided on a membership basis, a login is performed using a user ID and a password. Therefore, the color conversion table created in association with the user ID is stored in a storage device in the form of a database. It is good to register. If necessary, the date of examination, address, name, and other information specific to the individual are received from the color-blind person and registered in the database.

(Color Correction Process) When a person with color vision impairment wants to view a general markup language document, the user inputs a URL to the client 10. The request for the markup language document indicated by the URL by the browser of the client 10 is transmitted to the web server 5 via the conversion server 40.
If it is sent to 0, the first access will be the same as before
A login screen (password input screen) is sent from the web server 50 to the client 10. When the client 10 login display screen is displayed, the color-blind person enters a user ID and a password. In the same manner as before, personal authentication is performed using user ID and password.
This is performed in the B server 50. Web server 5
0 determines whether or not the user ID sent from the client 10 is registered in the database. If registered, the WEB server 50 sends the conversion table for the color-blind person of the client 10 and the communication address of the client 10 to the conversion server 40.

The conversion server 40 temporarily stores the transmitted communication address and the conversion table in an internal memory, and thereafter uses the color correction (conversion) program to execute the WEB server 5.
It receives a markup language document transmitted from 0 (a markup language document requested by a URL from the client 10), modifies a color-related command in the markup language document, and transfers it to the client 10.

The color conversion table is a table describing the correspondence between the information indicating the color before the conversion and the information indicating the color after the change.

An example of converting an HTML document is shown below. HT
In the ML document, for example, <BODY BGCOL
OR> = “# CCFFFF” TEXT = “# FF00
An instruction related to the display color is described, such as “FF” LINK = “# FF00FF”.

<BODY BGCOLOR> is a command for specifying the color of the front screen, and the character string following # such as #CCFFFF is a numerical value (hexadecimal) indicating the type of color. TEXT is an instruction for specifying a general character color, and LINK is an instruction for specifying the color of a character string indicating a link destination.

Therefore, every time a markup language document is transmitted from the WEB server 50 in response to a request from the client 10, the conversion server 40 receives the markup language document, and compares the color information before conversion described in the conversion table with the color information before conversion. It is detected whether or not the same color information (numerical value) is included in the color-related command. If the same is included, the color information is converted (color corrected) into the converted color information (S21). The conversion may be performed by converting the color information (the numerical value following the #) in the markup language document using a character string replacement function well known in word processing documents and the like.

The color-corrected markup language document is transferred to the client 10 of the color-blind person (S21). The markup language document displayed by the browser of the client 10 displays an image color-corrected for a color-blind person, so that the color-blind person can correctly recognize the content of the display.

Since the user ID of a healthy person is not registered in the database of the web server 50, the user ID input when the client 20 of the healthy person logs in the web server 50, the user ID on the database, The Web server 50 determines that the color correction is unnecessary by the comparison of the conversion table, and the conversion table is not sent to the conversion server 40. As a result, the conversion server 40 can execute the WE without performing the above-described color correction processing of the markup language document.
The markup language document output from the B server 50 is transferred to the client 20. Therefore, the client 20 displays the markup language document in a color defined in the original markup language document.

(Other Embodiments) In the above embodiment, the conversion server 40 communicates with the Internet 30 (providing general information).
Although installed between the servers 50, the conversion server 40 may be separated from the server 50 and operated independently. In this case, the conversion server 40 and the server 50 are connected to the Internet 30. Further, the clients 10 and 20 specify the conversion server 40 as a server for performing color correction on the HTML document received by the clients 10 and 20.

The conversion server 40 stores an HTML document for examining the degree of color vision impairment.
0,20 may be provided. The client 10,
It is preferable that a program for receiving the inspection response from the server 20 and determining the content of the color correction be installed in the conversion server 40. Further, the processing related to color correction executed on the server 50 side may be executed by the conversion server 40, and further, the information related to color correction of the user may be stored in the conversion server 40.

(Other Embodiments) 1) In the above-described embodiment, the conversion server 40 performs the color correction processing of the markup language document. However,
A conversion program for color correction defining the function of the conversion server 40 may be installed on the WEB server 50 as shown in FIG. Further, a conversion program for color correction may be installed on the client 10 as shown in FIG. In this case, the conversion table and the database are provided on the web server 50, and the change processing of the description of the HTML document is executed by the conversion program.

2) A table for color correction may be stored on the conversion server 40 side. For example, the proxy server has a word replacement function as one of the filter functions, and this replacement function may be used to replace the color component portion in the HTML document.

3) In the above-described embodiment, the user of the color-blind person is identified by the user ID on the Internet, but the identification information for specifying the color-blind person is as follows.
What is necessary is just to use a name, the device number of the client 10, a certificate, etc. At the time of registration, these identification information may be manually input by a color-blind person. As the device number, device number information stored in the client 10 may be automatically input. The certificate is issued by a third-party accredited institution, which indicates that the computer system is a color-blind person and that the content of the color-blind condition is stored in the client.

4) In the above-described example, the inspection (test) for color vision impairment is first performed. However, the above-described inspection may be performed every time the user logs in to the WEB server 50.

5) In the above-described embodiment, the client is described as an example of a personal computer. However, the client may be a color-displayed portable telephone or other information processing device having an Internet connection function.

6) In the above embodiment, the client 10
Has been shown as an example in which is directly connected to the Internet 30, but it may be connected to the Internet 30 via a communication server of a provider or a communication server of an in-house LAN.
