IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD

Abstract:

A decision unit decides whether or not a deblocking filter is applied to color difference components of pixels belonging to a line orthogonal to a block boundary in two adjacent blocks adjacent to each other sandwiching the block boundary of the decoded image, by using color difference components of pixels belonging to a line identical to a line used to decide whether or not the deblocking filter is applied to luminance components of the pixels belonging to the line orthogonal to the block boundary. The filtering unit applies the deblocking to the color difference components of the pixels for which it is decided that the deblocking filter is applied. The present technology can be applied to, for example, a case where encoding and decoding of an image are performed.
