摘要： An image encoder/decoder by which a partial image is encoded easily with a resolution meeting the user's demand, wherein the encoded amount of data is not increased and a necessary capacity of memory can be reduced. The image encoder has a tile decomposition portion which divides image data into tiles of N pixels×M pixels, a wavelet transform coding portion which extrapolates predetermined data at the peripheries of the tiles outputted from the tile decomposition portion and performs subdivision to perform wavelet encoding. A management information generating portion generates information for managing the encoded data in order that the encoded data outputted from the wavelet transform coding portion can be decoded for each tile and for each subband of the wavelet encoding. Also, a coded data integration portion links the encoded data encoded by wavelet encoding for each tile by using the output of the management information generating portion and adds the managing information to the encoded data.

摘要： Disclosed herein is a 3-D image display unit that can be controlled flexibly to protect the user from eyestrain and operated easily. The 3-D image display unit includes measuring means for measuring a display time of a 3-D image, parallax adjusting means for instructing 3-D image forming means to adjust the parallax of the 3-D image. In the case where the 3-D image display time measured by the measuring means exceeds a predetermined time, the parallax adjusting means instructs the 3-D image forming means to reduce the parallax of the 3-D image to be formed, thereby the display means comes to display a 3-D image having a small parallax. The user can thus be protected from eyestrain.

摘要： An image coding/decoding apparatus offers a visually high quality image at a very low bit rate. The image is divided into images for individual regions using its shape information. Each region is made into rectangle blocks by an extrapolation process, whereby each region can be sub-band coded. Finally, multiple extrapolated images which were formed by the extrapolating process, are appropriately coded or quantized.

摘要： A motion picture coding and decoding apparatus synthesizes a lower layer frame at a certain time by using first component area information of a lower layer preceding in the time and second component area information of a lower layer succeeding in the time. For an area where the first and second component areas overlapped, or for an area which is neither the first nor the second component area on the lower layer frame, lower layer frames preceding and succeeding in time are subjected to weighted average for synthetisization. For the area corresponding to the first component area only, the lower layer frame succeeding in time is used, and for the area corresponding to the second component area only on the synthesized lower layer frame, the lower layer frame preceding in time is used, for synthesizing the lower layer.

摘要： If coding is carried out on the block basis on subband coding of an image, the hierarchical characteristic which a subband image inherently has would be lost. Thus, efficient coding is to be carried out while holding the hierarchical characteristic of the subband image. After the subband image is coded on the block basis, symbol information and coefficient information are decomposed and relocated for every subband before producing coded data.
