摘要： To improve the data compression ratio in the data compression/decompression method utilizing the down-sampling process. Image data in a DS area division unit (130) is divided into a plenty of DS areas and DS areas which are not important are converted into contracted data of the block size by down-sampling in a down-sampling unit (131). A relocation unit (132) allocates two or more contracted data in one DS area, inserts file data into the other portion in the DS area, and removes the DS area where no contracted data is allocated, thereby reducing the entire image size. The image data thus contracted is inputted into a JPEG encoder (14) and subjected to a DCT process and a quantization process for each block. When performing restoration, decompression is performed by the JPEG decoder and the original location is restored. As for the contracted data, interpolation is performed to restore the image data.

摘要： A video signal is encoded at a plurality of coding layers exhibiting different spatial resolutions. An input video signal is spatially scaled down into a resolution-lowered video signal that exhibits a resolution lower than the video signal. The resolution-lowered video signal is encoded with a decoding procedure to obtain first coded data and a decoded signal. The decoded signal is spatially scaled up through a high-resolution procedure with reference to the input video signal so that the decoded signal has a smaller error with respect to the input video signal, to obtain a high-resolution scaled-up video signal. The input video signal is encoded through inter-spatial resolution prediction using the high-resolution scaled-up video signal as a predictive signal, to obtain second coded data that exhibits a resolution higher than the resolution-lowered video signal.

摘要： An input video signal is encoded at a plurality of coding layers exhibiting different spatial resolutions. The input video signal is spatially scaled down to a resolution-lowered video signal that exhibits a resolution lower than the video signal. The resolution-lowered video signal is encoded by using a quantization parameter, with a decoding procedure, thus obtaining first coded data and a decoded signal. The decoded signal is spatially scaled up through a high-resolution procedure for controlling high-frequency components estimation depending on the quantization parameter, thus obtaining a high-resolution scaled-up video signal. The input video signal is encoded through inter-spatial resolution prediction using the high-resolution scaled-up video signal as a predictive signal, thus obtaining second coded data that exhibits a resolution higher than the resolution-lowered video signal.

摘要： An input video signal is encoded at a plurality of coding layers exhibiting different spatial resolutions. Decoded is a given signal coded at a lower coding layer lower than a specific coding layer among the plurality of coding layers to generate a decoded signal of the lower coding layer. Spatial interpolation is applied to the decoded signal of the lower coding layer to generate an upscaled decoded video signal. The spatial interpolation is an upscaling procedure to upscale the decoded signal of the lower coding layer into a spatial resolution of the specific coding layer. A spatial high-frequency components estimation and scale up procedure is applied to the decoded signal of the lower coding layer to generate a high-frequency components signal. The upscaled decoded video signal and the high-frequency components signal are subtracted from the input video signal exhibiting a spatial resolution of the specific coding layer to produce a predictive-error signal. Then, the predictive-error signal is encoded at the specific coding layer to generate an output bitstream. The decoding, spatial interpolating, spatial high-frequency components estimating and upscaling, and encoding procedures are executed at, at least, the specific coding layer among the plurality of coding layers except the lowest coding layer exhibiting the lowest spatial resolution thereamong.
