Image displaying system of environment-adaptive type, presentation system, and image processing method and program
First Claim
1. An image display system of environment-compliant type which corrects a color of an image and displays the image, based on visual environment information generated by visual environment detection means which detects a visual environment in a display region of the image, the image display system comprising:
- colored-light information processing means which converts a given color within the visual environment information into a coordinate value within a given color space, and obtains a coordinate value forming a complementary color pair with the converted coordinate value, based on a coordinate value within the given color space of the given color within a given reference environment and the converted coordinate value; and
correction means which corrects input-output characteristic data for display that is used by means of displaying the image, based on the obtained coordinate value forming the complementary color pair.

Abstract
To provide an environment-compliant image display system, a presentation system, an image processing method, and a program, a colored-light information processing section 140 is used to create XYZ values that take into account a visual environment, based on colored-light information (more precisely, RGB or XYZ tristimulus values) that has been measured by a colored-light sensor 60, and a profile management section 130 is used to correct the input-output profiles of the projector.

6. A presentation system of environment-compliant type which corrects a color of a presentation image and displays the presentation image, adapting to a visual environment, the presentation system comprising:
-
visual environment detection means which detects the visual environment within a display region of the presentation image, and creates visual environment information;
colored-light information processing means which converts the visual environment information into a coordinate value within a given color space, and obtains a coordinate value forming a complementary color pair with the converted coordinate value, based on a coordinate value within the given color space of the given color within a given reference environment and the converted coordinate value;
correction means which corrects input-output characteristic data for display that is used by means of displaying the image, based on the obtained coordinate value forming the complementary color pair; and
display means which displays the presentation image, based on the corrected input-output characteristic data. - View Dependent Claims (7, 8, 9, 10)

11. An image processing method of environment-compliant type which corrects a color of an image adapting to a visual environment, the method comprising:
-
a step of detecting a visual environment;
a conversion step of converting the detected visual environment into a coordinate value within a given color space;
a coordinate-value calculation step of obtaining a coordinate value forming a complementary color pair with a coordinate value converted by the conversion step, based on a coordinate value within the given color space of the given color in a given reference environment and the converted coordinate value;
a correction step of correcting input-output characteristic data for display, based on the obtained coordinate value forming the complementary color pair; and
a step of displaying an image, based on the corrected input-output characteristic data. - View Dependent Claims (12, 13, 14, 15, 16, 18, 19, 20, 21)

17. A program embodied on an information storage medium or in a carrier wave, which is a program for correcting a color of a presentation image and displaying the presentation image, adapting to a visual environment, the program implementing in a computer:
-
visual environment detection means which detects the visual environment within a display region of the presentation image, and creates visual environment information;
colored-light information processing means which converts the visual environment information into a coordinate value within a given color space, and obtains a coordinate value forming a complementary color pair with the converted coordinate value, based on a coordinate value within the given color space of the given color within a given reference environment and the converted coordinate value;
correction means which corrects input-output characteristic data for display that is used by means of displaying the image, based on the obtained coordinate value forming the complementary color pair; and
means which controls a display means to display the presentation image, based on the corrected input-output characteristic data.
