摘要： A video coding device capable of making coded data have a hierarchical structure, a specified area of each frame is selected. The position and the shape of the selected area are encoded, a pixel value of the selected area is encoded as slower-layer coded data, a pixel value of a whole image is encoded as first upper-layer coded data by using pixel values of already decoded images of the lower-layer and the first upper layer and a pixel value of the selected area is encoded as second upper-layer coded data by using pixel values of already decoded images of the lower-layer and the second upper layer.

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 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： An image coding apparatus inputs pixel data of a part image of high resolution. An upper layer coding portion (101), a second shape data generating portion (102), and a second shape data coding portion (103) perform coding of shape data and pixel data in the upper layer. A down sampling portion (104) generates pixel data of low resolution. A lower layer coding portion (105), a first shape data generating portion (106), and a first shape data coding portion (107) code shape data and pixel data in the lower layer.
