摘要： Data decoded by a decoding section (101) are compressed by a compressing section (102) and then stored in a forecast/display frame memory section (103). The data in the forecast/display frame memory section (103) which are required to decode the other frames in the decoding section (101) are expanded and supplied to the decoding section through an expanding A section (104). The decoding section (101) uses the data restored by the expanding operation to decode the image data subjected to the forecast encoding operation. On the other hand, the display frame is subjected to the expanding operation at an expanding B section (105) after it has been read out from the forecast/display frame memory section (103), the expanded display frame then being output and supplied to a display device. Thus, the data stored in the forecast/display frame memory section (103) can be compressed to reduce the size of memory capacity.

摘要： Data which has been decoded by a decoding portion 101 are compressed by a compressing portion 102 and stored in a prediction/display frame memory portion 103. From the data stored in the prediction/display frame memory portion 103, any data required for decoding other frames in the decoding portion 101 are decompressed through a decompressing A portion 104 and supplied to the decoding portion 101. Alternatively, data to be displayed is read from the prediction/display frame memory portion 103, decompressed at a decompressing B portion 105 and supplied to a display apparatus. Writing to and reading from the above-mentioned prediction/display frame memory portion 103 is controlled by an address controlling portion 106. Since compressed data are stored in the prediction/display frame memory portion 103, the memory capacity can be decreased.

摘要： A method and apparatus of digital image decoding is provided for reducing compression-related deterioration of an image to a minimum with a reduced storage capacity. The digital image decoding apparatus is equipped with a compression rate judging section for judging an optimal rate of compression for effecting the least deterioration to the image based upon the size of image in connection with the storage capacity of a frame memory. A compressing section compresses decoded data based upon the optimal rate of compression and sends the compressed data to a predictive/display frame memory for storage. An expanding A section expands the compressed data based upon the optimal rate of compression and sends the expanded data to a decoding section when the expanded data is required. An expanding B section reads out the compressed data of a display frame from the predictive/display frame memory and expands the compressed data based upon the optimal rate of compression and sends the expanded data to a display unit for display.

摘要： Encoding and decoding are uniformly carried out for a plurality of chroma formats. Based on a control signal for providing a chroma format type of an input moving image signal, in the case of a chroma format of 4:2:0 or 4:2:2, a first intra prediction mode deciding unit and a first intra prediction image generation unit are applied to a luminance component of the input moving image signal, and a second intra prediction mode deciding unit and a second intra prediction image generation unit are applied to a chrominance component. In the case of a chroma format of 4:4:4, the first intra prediction mode deciding unit and the first intra prediction image generation unit are applied to all color components to carry out encoding, and a variable length encoding unit multiplexes the control signal as encoding data to be applied to a moving image sequence unit on a bit stream.
