Abstract
To provide an environment-compliant image display system, image processing method, and information storage medium that enable correction of images within a shorter time, a Y value of color signals (Y3, x3, y3) measured by a color light sensor 60 and converted by an Y3x3y3 conversion section 143 is replaced with Y1, which is a Y value of an ideal environment, by a Y replacing section 142; color difference between the replaced color signals (Y1, x3, y3) and ideal color signals (Y1, x1, y1) is obtained by a color difference calculation section 145; and image display information is corrected by using that color difference (Δx, Δy).
Claims11
An image display system of environment-compliant type which corrects image display information for displaying an image and displays the image, based on viewing environment information obtained by viewing environment detection means which detects a viewing environment in a display area of the image;
- the image display system comprising:
- brightness correction means for correcting brightness information included in the viewing environment information to conform with brightness of an ideal environment, based on the viewing environment information, when brightness of the image in the viewing environment differs from brightness of the image in the ideal environment;
- color difference calculation means for calculating color difference between color information included in the viewing environment information, in which the brightness information has been corrected, and color information of the image in the ideal environment;
- and
- image correction means for correcting the image display information, based on the calculated color difference.
An image display system of environment-compliant type which corrects image display information for displaying an image and displays the image, based on viewing environment information obtained by viewing environment detection means which detects a viewing environment in a display area of the image;
- the image display system comprising:
- a brightness correction section which corrects brightness information included in the viewing environment information to conform with brightness of an ideal environment, based on the viewing environment information, when brightness of the image in the viewing environment differs from brightness of the image in the ideal environment;
- a color difference calculation section which calculates color difference between color information included in the viewing environment information, in which the brightness information has been corrected, and color information of the image in the ideal environment;
- and
- an image correction section which corrects the image display information, based on the calculated color difference.
An image processing method of environment-compliant type which corrects image display information for displaying an image, based on viewing environment information indicating a viewing environment in a display area of the image, the image processing method comprising:
- a step of generating the viewing environment information;
- a color difference detection step of detecting color difference between a given image in the viewing environment and the given image in an ideal environment, based on the generated viewing environment information;
- and
- a step of correcting the image display information, based on the detected color difference.
A computer-readable information storage medium which stores program for correcting image display information for displaying an image, based on viewing environment information indicating a viewing environment in a display area of the image, the information storage medium comprising program to implement on a computer:
- means which generates the viewing environment information;
- color difference detection means which detects color difference between a given image in the viewing environment and the given image in an ideal environment, based on the generated viewing environment information;
- and
- means which corrects the image display information, based on the detected color difference.
