摘要： In an image data compression method to be employed in coding digital image data whose pixels are represented by n bits and which include 2.sup.n different types of runs, while a run length of a current run is counted, a value representing a run type of the current run is predicted. The prediction is repeated till a predicted value coincides with an actual value of the run type of the current run. When a predicted value does not coincide with the actual value of the run type of the current run, a run length for an imaginary run having the predicted value is regarded as zero and the run length 0 of the imaginary run is entropy coded. On the other hand, when a predicted value coincides with an actual value, the actual run length of the current run is entropy coded.

摘要： A stereoscopic image supplier acquires stereoscopic image data in a side-by-side layout format. Visual information supplier acquires visual information to be added to a stereoscopic image. Based on a 3D display for displaying a stereoscopic image, a 3D display information supplier acquires the coordinates of portions that are not used for 3D display representation as the coordinates of the pixels with which visual information is combined. An image synthesizer combines visual information obtained at Step S2 with the pixel at the coordinates set at Step S3. Visual information is combined with all the portions at the coordinates to be processed, and the image with visual information synthesized is stored in a stereo image storage. In this way, if additional information is added to the stereoscopic image, no uncomfortable feeling will occur when the image is viewed in stereoscopic vision.

摘要： A moving image/audio recording apparatus in which failure of recording due to erroneous operation and operation timing deviation can be prevented is implemented. Moving image data and audio data prior to the start of recording are multiplexed by a multiplexing unit 103. The multiplexed data is temporarily stored in a built-in memory 104. A control unit 106 which has received an instruction to start a going back recording changes the going back recording start time to the time subsequent to the time when the encoding conditions or channels are changed to those at the time of the instruction to start recording if the encoding condition or the channel at the time which goes back by a period of time preset as the going back time is different from that at the time of the instruction to start recording and consecutively reads out the multiplexed data from the memory 104 for recording them in a recording unit 105 via a changeover switch 108. If the first frame at the time to start the going back recording on the recording unit 105 is not a key frame, recording is started with a key frame which is closest to the time to start the going back recording.

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.
