Abstract

Improved color image display accuracy can be achieved across a computer network by obtaining information characterizing the color response of display devices associated with a client residing on the computer network, and using the information to modify style sheets delivered to the client for displaying web pages. Display accuracy can be achieved in a network having both multiple clients that submit images and multiple clients that receive images, such as in the case of an online auction or photo web site. The information can be obtained, for example, by guiding clients that download images or other visual content through a color profiling process that profiles the color response of the display device. For example, such guidance may take the form of a series of instructional web pages that are delivered to the client. The web pages can be made interactive to enable collection of color characterization data from the client.

communicate the web page to the client; and

set a color of an object in the web page based on the color value in the style sheet.

19. The computer-readable medium of claim 18, wherein the instructions cause the processor to set a color of an object by setting at least one of a text color, a background color, a color of a table cell, and a color of a region of the web page.

20. The computer-readable medium of claim 18, wherein the instructions cause the processor to:

set a color of an image tagged in the web page based on the color response of the display device associated with the client; and

communicate the tagged image to the client.

21. The computer-readable medium of claim 20, wherein the instructions cause the processor to:

generate a color profile based on the color response of the display device;

formulate the style sheet based on the color profile; and

set the color of the image based on the color profile.

22. The computer-readable medium of claim 20, wherein the instructions cause the processor to:

communicate the web page from a first server; and

communicate the tagged image from a second server.

23. The computer-readable medium of claim 20, wherein the instructions cause the processor to:

communicate the web page from a first server; and

communicate the style sheet from a second server.

24. The computer-readable medium of claim 20, wherein the instructions cause the processor to characterize the color response of the display device by guiding the client through a color profiling process.

25. The computer-readable medium of claim 24, wherein the instructions cause the processor to guide the client through the color profiling process by delivering one or more color profiling web pages to the client.

26. The computer-readable medium of claim 24, wherein the instructions cause the processor to:

generate a web cookie for the client containing information representing a result of the color profiling process; and

communicate the web cookie to a server that communicates the style sheet.
