    摘要： A motion picture reproducing apparatus having a file composed of a header an image track on which image data have been recorded for a predetermined period of time and a sound track on which sound data have been recorded for the predetermined period of time. The image and sound data of the file are provided with track and data identifying numbers by a track identifying section and a data identifying section, respectively, and are outputted to a data synchronizing section. The data synchronizing section reads in order the image data and the sound data on the basis of the control information of the header, synchronizes the image data and the sound data to which the same data identifying numbers have been imparted with reference to the track and data identifying numbers which have been given to the image data and sound data, and outputs the image and sound data to reproduction units.

    摘要： An image data compression method in which reductions in data amount are achieved by deleting some pixel data. Compression is achieved by performing a reading step to read an image as plural pixel data and a deleting step to delete some of the pixel data. A prediction error calculating step calculates a prediction error that represents the difference between the color value pixel data of a pixel in question and the predicted color value thereof, as predicted by a prescribed prediction method from the pixel data of a pixel adjacent thereto. An area classifying step classifies the pixel data of the entire image area into either an abrupt color change areas type in which the prediction error is large or a nonabrupt color change area in which the prediction error is small. The deleting step is performed only on the pixel data classified in the nonabrupt color change area; deleted-position information is appended to the non-deleted pixel data that indicates the position of a pixel whose data has been deleted. This improves the quality of reproduction, since no pixel data are deleted where large errors would be expected to occur in reproduction.

    摘要： A video data reproducing apparatus and method therefor having a file controller section for controlling video data recorded on a first recording medium at random positions, and further, having a second recording medium for recording the video data in a serial manner. The apparatus includes a decision section for judging whether to select the video data of either the first recording medium or the second recording medium. A first reading section reads out the data of the first recording medium through the file controller section when the first recording medium is selected by the decision section, and a second reading section reads out the video data to a buffer memory from the second recording medium, without any intervention of the file controller section, when the second recording medium is selected by the decision section.

    摘要： Disclosed is an image processing system including an image input unit, an extraction unit, a plurality of compression process parts and a selection unit to compress a 1-frame image down to a less amount of color information. The image input unit takes in a plurality of frame images per frame. The extraction unit extracts each of the taken-in frame images per unit area of a designated size. The plurality of compression process parts effects compression processes different from each other with respect to pels contained in each unit area. The selection unit selects one compression process part from the plurality of compression process parts for compressing the unit area of the designated size.
