摘要

An image processing apparatus includes a selection section for selecting and retrieving a significant part in terms of resolution from a bit steam of an image signal which is input to each pixel of an image display apparatus; and an extension and correction section for extending and correcting the significant parts of the image signals selected by the selection section in a low-frequency part which includes a plurality of consecutive image signals having a first signal value and a plurality of consecutive image signals having a second signal value which is different from the first signal value by a prescribed value, wherein the significant parts are each extended and corrected by being supplemented with a prescribed number of bits, such that the first signal value smoothly changes to the second signal value.
