Abstract
Abstract An image information processing apparatus includes a detector for detecting the move vector of an image of the present relative to that of the preceding field; a circuit for processing, on the basis of the move vector, the image of the present field stored in a field memory; and a residual memory for storing the residual information calculated during the period in which the image data of one horizontal scanning line is inputted. The residual information stored in the residual memory is shunted into a blank area of the field memory during a predetermined interval after the period in which the image data is input. The processing circuit performs a wobble correction to correct any shaking of the image between fields or compresses the data quantity of the dynamic image in image transmission, and the information of one entire picture is processed after being divided into a plurality of blocks, whereby the storage capacity of the residual memory can be widely reduced.
