Abstract
To provide an environment-compliant image display system, information storage medium, and image processing method capable of accurately reproducing the color appearances of an image, an information generation section (160) that uses a calculation method based on an appearance model is used to generate a 3D-LUT in a LUT storage section (122), based on viewing environment information from a color-light sensor (60) that detects the viewing environment, device color gamut information, and corresponding-color information of the sRGB standard, and a projector color conversion section (120) is used to convert an image signal based on the 3D-LUT.
Claims15
An environment-compliant image display system which displays an image based on conversion information that is generated based on viewing environment information obtained by viewing environment detection means for detecting the viewing environment when an image display area is seen, and is used converting an image signal, the image display system comprising:
- information generation means for generating the conversion information by performing a calculation that is based on an appearance model, in order to display an image that conforms to a reference standard, based on the viewing environment information and color information of the reference standard, the color information having predetermined standard environment information;
- and
- image display means for converting the image signal, and displaying an image based on the generated conversion information.
A computer-readable information storage medium which stores a program for displaying an image based on conversion information that is generated based on viewing environment information obtained by viewing environment detection means for detecting the viewing environment when an image display area is seen, and is used converting an image signal, the information storage medium storing a program for causing a computer to function as:
- information generation means for generating the conversion information by performing a calculation that is based on an appearance model, in order to display an image that conforms to a reference standard, based on the viewing environment information and color information of the reference standard, the color information having predetermined standard environment information;
- and
- means for converting the image signal, based on the generated conversion information, and causing an image display means to display an image.
An image processing method for an image display system which displays an image based on conversion information that is generated based on viewing environment information obtained by viewing environment detection means for detecting the viewing environment when an image display area is seen, and is used converting an image signal, the image processing method comprising:
- acquiring the viewing environment information;
- generating corresponding-color information that indicates a corresponding color that reproduces a color of a reference standard based on the acquired viewing environment information and color information of the reference standard, by performing a calculation based on an appearance model, the color information having predetermined standard environment information;
- generating the conversion information, based on the obtained corresponding-color information and color gamut information indicating a color gamut that is reproducible by display means that displays the image;
- and
- converting the image signal based on the generated conversion information.
