ABSTRACT:
A video apparatus with image memory function has a memory of three ports (one for write, two for read), memory read control units corresponding to two independent read ports and adapted to read a desired area (first area) from a first read port and an area (second area) which contains the first area and is wider than the first area from a second read port, and a memory write control unit. With this construction, an input video signal is written to the memory, starting with a write head address designated by the memory write control unit, the first and second fields to be read during the next field are determined during the period of vertical blanking, a next write head address is determined to be after the first area, and a signal of the first area is delivered as an output video signal.
