    Abstract: A video signal processing apparatus comprising an edge detecting means for detecting an edge portion of an image to color difference signals; a region dividing means for dividing, except the detected edge portion, the image into regions determined in accordance with the levels of luminance signal; and an intra-region averaging means for averaging the color difference signals in the individual divided regions. The color difference signals in the edge portion are outputted directly, while the color difference signals in the divided regions are outputted after being averaged. Except the edge portion where variations of the color difference signals are conspicuous, the image is divided into one or more regions determined in accordance with the luminance signal levels, and the color difference signals in the individual regions are averaged. Since the color difference signals are averaged in the portion where color variations are little, any video signal noise that causes color nonuniformity and so forth can be eliminated in such portion having little color variations.

    Abstract: PROBLEM TO BE SOLVED: To provide an image encoder and a method thereof capable of encoding many image signals with a motion such as HDTV signals with high image quality without a time delay and to provide an image decoder and a method thereof. SOLUTION: A processor 130 -1 in a division image encoder 120 -1 encodes two-dimensional sub image signals resulting from applying 1/N division to a two-dimensional image signal by an image division device 110 and calculates a feature parameter denoting the complicatedness of the image on the basis of the encoded result. A share bit rate arithmetic section 171 calculates a proper bit rate to encode an image signal of a succeeding frame on the basis of a temporal change in the feature parameter denoting the complicatedness of the image and shares the bit rate to a plurality of the processors 13 -1 . A plurality of the processors 130 -1 encodes sub image signals at a designated bit rate. A video stream integral device 160 integrates the encoded sub image signals to generate and output the video stream. COPYRIGHT: (C)2003,JPO

    Abstract: PURPOSE:To segment a desired image from a display image with a simple operation. CONSTITUTION:A ruled mark to divide the display image into blocks is displayed by superimposing on the display image. The block (shown after hutching is applied in figure) including the contour of an image to be segmented out of the blocks divided by the ruled mark is designated. The connecting direction of a designated block is decided, and the contour of the image to be segmented is decided by a mask operator in accordance with the connecting direction.
