摘要： In an image signal encoding method for encoding an image signal using motion compensation, a motion vector is found by means of a block matching method, a first distortion SEmc of motion compensated prediction associated with the motion vector, and a second distortion SEnomc of prediction without motion compensation are detected, the motion vector is used for for inter-picture prediction encoding when SEnomc>SEmc+K, with K being a constant greater than 0, and a vector having a value zero is used, in place of the motion vector, for inter-picture prediction encoding when SEnomc≦SEmc+K. In another aspect, a speed of motion in a sequence of pictures is detected, and for a part of the sequence of pictures detected to contain a quick motion, the prediction encoding is performed using one-way prediction encoding, and for a part of the sequence of pictures without a quick motion, prediction encoding is performed using bi-directional prediction encoding. In another aspect, the image signal is subsampled for each field, and a motion vector is determined using the field-subsampled image signal.

摘要： An encoding preprocessing part 1 extracts the amount of image feature relative to image data and passes the amount of image feature to a control part 2 as image feature amount information 11 and also sends image data 10 to an encoding part 3. The control part 2 determines whether there is a dissolve image or not based on the image feature amount information 11 and if it is determined that the image data 10 is the dissolve image, an encoding parameter 12 is set so that a configuration of GOP which is normally M=3 is changed into the configuration of GOP of M=2, and the encoding part 3 performs encoding based on the encoding parameter 12. As a result of that, a prediction error of a B-picture frame in a dissolve interval becomes substantially zero and on encoding in the dissolve interval, the amount of information occurrence in frames except I-picture and P-picture frames can be reduced and thus the amount of information occurrence as a whole can be reduced.

In a data arrangement of a digital video signal, an I picture which can be independently represented in a picture is divided into n areas in the vertical direction, and the data is arranged from the front of one GOP in the unit of area by giving a priority to an area located at the center of the screen. A playback picture is outputted by playing back the I picture read from the recording medium in the unit of area unit. In the case where the whole I picture area cannot be read within a definite time, the area which cannot be read are interpolated by the use of the data of the preceding screen.

摘要： In a motion-adaptive television signal processor, a field as a reference for a moving picture signal includes a signal delayed by a frame memory or a field memory. A non-standard signal is beforehand processed so as to separate Y and C signals, and the signal thus processed is input to a motion-adaptive processor to thereby reduce a deviation in center of gravity between a still picture signal and a moving picture signal on the timebase to thereby suppress unnatural motion of the picture.
