Abstract

The present invention provides a technique for providing color corrected images to a user over a network. In particular, the present invention allows multiple image providers to provide color corrected images to a user when the user'"'"'s computer and its associated devices are not calibrated and/or characterized, or the calibration and/or characterization data is not available over the network to the image providers. This abstract is provided for the sole purpose of complying with the rules requiring an abstract to allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure contained herein. This abstract is submitted with the express understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Claims

1. An image server to provide images to a client computer over a computer network, comprising

an image request server to receive a request from the client computer for data including an image;

a database checker to determine an unavailability of image display characteristics for the client computer;

a database of image display characteristics to adjust the requested image in accordance with a set of default image display characteristics for display on the client computer, the set of default image display characteristics being unrelated to the image display characteristics of the client; and

the image server to adjust the requested image in accordance with the set of default image display characteristics.

2. The server of claim 1, wherein the set of default image display characteristics are based on average image display characteristics of a plurality of computer clients having known image display characteristics.

3. The server of claim 2, further comprising, prior to selecting the set of default image display characteristics:

a statistical system to determine one or more sets of default image display characteristics based on an average image display characteristic of the plurality of computer clients having known image display characteristics.

4. The server of claim 3, wherein the statistical system to determine one or more sets of default image display characteristics comprises:

grouping logic to identify one or more groups of the computer clients having known image display characteristics; and

the statistical system to calculate a set of default image display characteristics for each group of computer clients having the known image display characteristics.

5. The server of claim 3, wherein the known image display characteristics are determined by requesting information from a user of the client computer.

6. The server of claim 3, further comprising:

the database of image display characteristics adjusted by removing known image display characteristics associated with a particular computer client when the computer client has been inactive for a period of time.

7. The server of claim 1, wherein the database is organized as a multidimensional parameter space of input and output image display characteristics.

8. The server of claim 7, wherein a multidimensional histogram is computed from the database to specify a fraction of image display characteristics which exhibit a specific set of parameters.

9. The server of claim 1, wherein the set of default image display characteristics is derived to address particular aspects of the client computer.

10. The server of claim 9, wherein the particular aspects of the client computer are obtained directly from an end user of the client computer.

11. The server of claim 10, wherein the particular aspects of the client computer comprise one or more of:

a type of a display for the client computer, a size of the display, the age of the display, a environment in which the display is used, a operating system software of the client computer, and a type of hardware controlling the display.

12. The server of claim 9, further comprising the image server tracking the client computer over a period of time and adjusting the display of the images beyond the default image display characteristics for at least one of:

a passage of time, a consequent degradation of a display, an amount of use of the display, a frequency which the user spends accessing the images, and a length of time the user spends accessing the images.

13. A method of adjusting an image comprising:

receiving by an image request server, a request for data including the image from a requesting system;

determining by a database checker, that no image display characteristics are available for the requesting system; and

adjusting the image in accordance with a set of default image display characteristics for display on the requesting system, the set of default image display characteristics being unrelated to the image display characteristics of the requesting system.

14. The method of claim 13, wherein the set of default image characteristics are determined based on an average image display characteristic of the plurality of computer clients having known image display characteristics.

15. The method of claim 14, wherein the average image characteristic is based on one or more of:

type of a display, size of the display, age of the display, a environment in which the display is used, an operating system software, and a type of hardware controlling the display.

16. The method of claim 14, further comprising:

removing an out-of-use known image display characteristic from the database when no requests from computer clients with the out-of-use known image display characteristic have been received for a pre-selected period of time.

17. The method of claim 13, further comprising:

tracking the client computer over a period of time; and

adjusting the display of the images beyond the default image display characteristics, based on the tracking, for at least one of;

a passage of time, a consequent degradation of a display, an amount of use of the display, a frequency which the user spends accessing the images, and a length of time the user spends accessing the images.

18. A method of adjusting an image comprising:

receiving by an image request server, an image request from an uncharacterized device;

determining by a database checker, that no image display characteristics are available for the uncharacterized device;

adjusting the image in accordance with a set of default image display characteristics, the default image display characteristics based on an average image display characteristic of a plurality of systems having known image display characteristics.

19. The method of claim 18, further comprising:

determining that no requests have been received from a system having a particular known image display characteristic in a period of time; and

removing the particular known image display characteristic from the average image display characteristic.
