Image signal processing apparatus, image signal processing method, image display apparatus, television receiver, and electronic device

摘要

An image signal processing apparatus includes: a basic movement level finding section for detecting a movement level of a video image; a timing controller for dividing one frame period into a plurality of periods containing a sub-frame A period and a sub-frame B period; a sub-frame A image signal generating section for subjecting, to a smoothing process, image signals which are supplied to pixels, in the sub-frame A period, in accordance with the movement level of the video image; a sub-frame B image signal generating section for subjecting, to an emphasizing process, image signals which are supplied to pixels, in the sub-frame B period, in accordance with the movement level of the video image; and an applied movement level finding section for finding, from a movement level of a video image of a current frame period and a movement level of a video image of a previous frame period, an applied movement level which is applied to the sub-frame A image signal generating section and/or the sub-frame B image signal generating section.
