Abstract
In order to inhibit artifacts (even when a special image has been input) a visual processing device is provided with a spatial processing portion extracting surrounding image information US from an input image signal IS, and a special image detection portion outputting a special image effect adjustment signal DS according to a degree of a statistical bias of the image signal IS. The visual processing device also includes a continuous changing portion outputting an effect adjustment signal MOD in which the special image effect adjustment signal DS is continuously changed between frames, an effect adjustment portion outputting a synthesized signal MUS in which the effect of the visual processing differs depending on the effect adjustment signal MOD, and a visual processing portion outputting a processed signal OS obtained by visually processing the image signal IS based on the image signal IS and the synthesized signal MUS.
