Abstract
An image processing device includes a decompression unit configured to decompress a compressed image signal, a gradation-dependent correction unit configured to perform gradation-dependent correction on the decompressed image signal, the gradation-dependent correction being a correction process in which the amount of correction varies among luminance gradations, and a compression error correction unit configured to perform compression error correction in which input luminance values are selectively offset, on the decompressed image signal which has yet to be subjected to the gradation-dependent correction.
