ABSTRACT:
The present invention relates to an apparatus and a method thereof for adjusting a luminance of an image signal. The apparatus includes a complementary circuit, a statistical circuit, a calculating circuit, and a blending circuit. The complementary circuit receives an image signal to generate a complementary luminance according to the luminance of the image signal. The statistical circuit receives the image signal to generate a statistical signal according to the luminance of the image signal. The calculating circuit receives the image signal, the complementary luminance, and the statistical signal to generate a calculated luminance of the image signal. The blending circuit generates an output image signal according to the calculated luminance and the luminance of the image signal. A video display device can thereby displays optimum pictures according to the output image signal.
