Abstract
An image displaying apparatus includes a line memory from which each line period segment of a first video signal is read during a half line period to produce a first half line period video signal segment, a frame memory from which each of line period segments contained in each frame period portion of a second video signal is read during a half line period, with a time reference set up in accordance with a synchronous signal contained in the first video signal, to produce a second half line period video signal segment, a signal selector operative to extract alternately the first and second half line period video signal segments to form a synthesized video signal for display, a dual image display portion for displaying images forming double window pictures in response to the synthesized video signal for display, a first timing signal generator for supplying the frame memory with a writing control signal, and a second timing signal generator for supplying the frame memory with a reading control signal, wherein the second timing signal generator is operative to control reading of the line period segments from the frame memory to produce the second half line period video signal segment to be performed for both of odd and even field period portions contained in each frame period portion of the second video signal when the first video signal is a noninterlaced video signal and the second video signal is an interlaced video signal.
