IMAGE DISPLAY SYSTEM,PROJECTOR,INFORMATION STORAGE MEDIUM AND IMAGE PROCESSING METHOD

摘要

An image display system which displays images with gradations corrected according to application environments,and which comprises a calibration signal generator(150)for generating calibration signals to respectively display first and second gradation correcting images in the same color and with two different gradations,a chromatic sensor(60)for measuring the brightness values of the first and second gradation correcting images projected on a screen respectively under an ideal environment and an application environment,a 1D−LUT generator(140)for generating 1D−LUT based on brightness values measured by the chromatic sensor(60),and a gradation corrector(170)for storing the 1D−LUT generated by the 1D−LUT generator(140)to correct gradation.DRAWING
