摘要： A deblocking filter 24 performs filtering of decoded image data obtained by decoding image data encoded for each block, so as to remove block distortion. If at least one of block sizes on adjacent sides of two adjacent blocks is extended larger than a predetermined block size, a filter setting unit 41 sets the tap length to an extended length to increase the strength of distortion removal, or sets a filtering object pixel range to an extended range. When a macroblock having an extended size is used, the degree of smoothing is increased, and pixels including those distant from the block boundary are subjected to filtering. Consequently, even when various block sizes are employed or when blocks of extended sizes are used, images of high image quality can be achieved.

摘要： An encoding apparatus and an encoding method, a decoding apparatus and a decoding method, a recording medium, and a program suitable for encoding image signals with a higher compression ratio for transmission or accumulation. In an arithmetic coding section, from among the syntax elements of input image compression information, the frame/field flag is first encoded by a frame/field flag context model. When the macroblock to be processed is subjected to frame-based encoding, a frame-based context model, specified in the current H.26L standard, is applied. On the other hand, when the macroblock to be processed is subjected to field-based encoding, a field-based context model is applied for the syntax elements described below. The present invention is applied to an encoder for encoding image information and a decoder for decoding image information.
