Image display apparatus

Abstract

There are provided a light source () having a plurality of light emitters, each of the light emitters, whose light-emission period is controlled separately, emitting one color of a plurality of colors; an image signal analyzer for analyzing an input image data, and determining a timing of light emission for each light emitter; a light source controller () for controlling the light-emission period for the light source based on the light-emission timing for each light emitter, such that the light-emission period is not shorter than a light-emission period of a predetermined minimum time length light-emission period; a light detector () for detecting the light emitted in the light-emission period of the minimum time length, and outputting the average light-emission peak values (Ir, Ig, Ib); and a peak value corrector () for generating correction values (d_Ir, d_Ig, d_Ib) for controlling each of the average light-emission peak values (Ir, Ig, Ib) to become equal to corresponding one in the reference peak values (tIr, tIg, tIb) stored in a memory (). Even when the light-emission period is changed according to the input image, the color balance of the image is maintained constant.
