Patent attributes
A visual processing section 120 is provided which performs visual processing on a pixel-by-pixel basis according to a predetermined function defining a relation between a pixel value of a target pixel which is a pixel under visual processing and a pixel value of the target pixel after subjected to the visual processing. An input signal processing section 150 is further provided which performs, on a pixel-by-pixel basis, at least one of signal processing to restore resolution of an image data input to the visual processing section 120 and signal processing to correct signal deterioration due to the visual processing. In the input signal processing section 150, the at least one signal processing is performed according to a gain determined by using the function.
