ープレコーダ。[Claims for Utility Model Registration] A video device equipped with a tracking control means that performs tracking control by displacing a video head that reproduces a video signal recorded on a magnetic tape using an electromechanical converter. The tape recorder is provided with a memory means for storing image information based on a video signal reproduced by the video head, and a memory control means for controlling write operation and read operation of the memory means, and the tape recorder is provided with a memory means for storing image information based on a video signal reproduced by the video head, and a memory control means for controlling write operation and read operation of the memory means, and the tape recorder is provided with a memory means for storing image information based on a video signal reproduced by the video head. A video tape recorder characterized in that image information based on a reproduced video signal is selectively stored in the memory means, and the image information stored in the memory means is arbitrarily repeatedly read out to perform interpolation of the image information. .
