Environment-compliant image display system, projector, and program
First Claim
1. An environment-compliant image display system which corrects an image, based on environmental information that expresses a viewing environment in a display area in which the image is displayed, and displays the image, the image display system comprising:
- correction means for correcting input-output characteristic data for display that is used by image display means which displays the image, in such a manner as to increase an output value in at least a lower grayscale range when the environment is affected by ambient light, based on the environmental information.

Abstract
An environment-compliant image display system, projector, and program that enables the reproduction of appropriate colors even when affected by ambient light. The projector has a color control processing update section that corrects colors by adjusting a LUT in a 3D-LUT storage section and brightness by adjusting a grayscale characteristic in a ID-LUT storage section, in order to increase the output in at least a lower grayscale range if the environment is affected by ambient light, based on environmental information that has been measured by a color light sensor.

10. A projector which corrects an image, based on environmental information that expresses a viewing environment in a display area in which the image is displayed, and displays the image, the projector comprising:
correction means for correcting input-output characteristic data for display that is used by image display means that projects the image towards the display area to display the image, in such a manner as to increase an output value in at least a lower grayscale range when the environment is affected by ambient light, based on the environmental information.
