ABSTRACT:
An image display control device calculates a lighting luminance after reduction in luminance and an image correction coefficient by real-time calculations of a common calculator. The common calculator is controlled by microcodes stored in a code table. When correcting an image, chroma correction is enhanced to suppress a decrease in chroma due reduction in luminance, and a flicker is prevented by series infinite impulse response (IIR) filtering processes. When the image has a low average luminance but has a high chroma, a decrease in chroma is suppressed by limiting a reduction in lighting luminance.
