PURPOSE:To prevent the effect of an image pickup of a blur of a TV camera from being given onto a picture by providing an image pickup means, a means applying A/D conversion to the output, a picture memory, and a movement detecting means and using the output of the movement detecting means so as to control the location to be read in reading a part of the content of the pattern memory. CONSTITUTION:The image pickup tube 4 is activated by a synchronizing signal Sy generated from a synchronizing signal generating circuit 6 and scans the scanning range 3. The image pickup output is used as it is when an analog memory is used for the frame memory 5 and digitized when a digital memory is used therefor, and the result is written in the frame memory 5. The data is read together with the write from the frame memory 5 and the signal before one frame at just the same location as the picked up by the image pickup tube 4 is read in the timing of the same mode II. The signal written in the frame memory, that is, the M-th frame signal and the signal read from the frame memory, that is, (M-1)th frame signal are inputted to the movement detection circuit so as to dynamic vector between the frames.
