ABSTRACT:
A system provides an image displaying technique that provides stable high contrast even in an area having high brightness. Based on information about an average brightness level of a digital luminance signal, black-correction processing which decreases a brightness level by offsetting the brightness level to the minus side, and increase processing which increases a contrast gain within a dynamic range, are performed for an analog luminance signal or a digital luminance signal, enabling improvement in contrast even where brightness is intense.
