    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.

    摘要: The method comprises a read-out step for reading out the image data from a predetermined recording medium according to a frame unit; an image outputting step for image-outputting the frame data read out in the read-out step; a time measuring step for measuring a reproductive processing time taken from a start of reading out in the read-out step to an end of outputting of an image in the image outputting step according to a frame unit; a predicting step for predicting an image output time of next frame data to be reproduced next to the frame data on the basis of the reproductive processing time measured in the time measuring step; a detecting step for detecting an image output time set per frame data from the image data; and a determining step for determining next frame data to be reproduced next to the frame data in accordance with the image output time predicted in the predicting step and the image output time detected in the detecting step.
