摘要： At the encoding side, a sum of code lengths of a block is calculated and stored in a memory for each of block lines (stripes); and at the decoding side, when decoding of one block is completed, a head address of a code in the next block is calculated utilizing a sum of an amount of codes utilized for the decoding operation and code lengths for each of the stripes. The rotation process of an image utilizing encoded data is performed in accordance with the head address. Further, at the encoding side, colors of pixels in a predetermined block is determined, and encoding operation is performed block by block for only those blocks including pixels of different colors. At the decoding side, an address of block data for sequentially constructing a rotated image is controlled to decode the pixels in the block, and finally the rotation process is performed on the pixels in the block in accordance with the color of the pixels.

摘要： When image data coded by a DCT coding method in a predetermined block size is to be decoded, an image processing apparatus extracts necessary DCT coefficients of a block on the basis of an enlargement/reduction ratio determined in advance, then decodes the extracted DCT coefficients. Thereby it is possible to produce a reduced image at high speed without using a memory of high capacity.

摘要： An amount of data coded in the past is detected at a prescribed period. Criteria for deciding whether a pixel block of interest is to be coded by processing for motion-compensated coding of interframe difference, processing for coding of interframe difference without motion compensation or processing for intraframe coding are adjusted based upon the amount of code detected.
