IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD

Abstract:

The present technology relates to an image processing device and an image processing method that make it possible to suppress block distortion. In accordance with a block structure having a hierarchical structure in which a transform block, a prediction block, and a coding block are unified, a bitstream is decoded and a decoded image is generated. A deblocking filter is applied to pixels of a line orthogonal to a sub-block boundary that is a boundary between sub-blocks obtained by dividing the transform block of the decoded image. The present technology can be applied to, for example, a case where encoding and decoding of an image are performed.
