摘要： The correlation between adjacent frames of a moving-picture signal is utilized to code and decode the signal while detecting the motion of each block of an image. There is provided a differential amplitude suppressing circuit which nonlinearly suppresses the amplitude of coded block data of an interframe difference based upon a threshold value for detection of motion. This circuit suppress the amplitude greatly when a detected value of motion is great in order to suppress the increase in the amount of coded data so that the reproduced moving image may be followed more faithfully. When the motion is small, the suppressing characteristics are reduced to improve the subjective quality of image. Further, the image signal sequence is integrated with time for each frame using a time integration circuit, the output of which is stored in a frame memory and read out at the same time. Therefore, the apparatus does not become bulky, and it is possible to eliminate the decrease in coding efficiency and the increase in generation of information by maintening reasonable delay time and proper interframe correlation.

摘要： An image encoder and an image decoder which perform the image displacement other than parallel displacement on a relatively small scale and with which the processing time can be reduced and estimation with a high precision is enabled. The constitution for compression-coding the input image comprises a movement compensating means which detects the frame-to-frame movement of the blocks into which the input image is divided. The constitution further comprises a movement detection unit which includes a deformed block matching section which deforms only integer pixels, i.e. real sampling points present in a partial region corresponding to a reference image for movement detection into predetermined formats, cuts the deformed pixels out, and compares the cut-out deformed pixels with the integer pixels of the blocks of the input image and which outputs a moving vector which gives a minimum error extracted by the coordinate designation and a movement compensation unit which includes a corresponding point determination section which includes the deformed block matching section, correlates the blocks of the reference image in accordance with movement parameters obtained from comparison output, designates the coordinates, deforms and determines the block, and which outputs a predicted partial image. Further, an image decoder is so constructed as to correspond to the construction of the encoder. Moreover, the image decoder calculates the coordinates with a plurality of movement vectors by using also the coordinate values of the half-pixels of the reference image in a movement compensating means and subjects the obtained pixel values to a deformation processing by using a deformation pattern in accordance with a deformed pattern.
