Abstract

PURPOSE: To perform a master-slave display without any deterioration in picture quality by providing a deflecting circuit which makes a scan on the whole display part with an aspect ratio c:d at a double speed, making a double-speed display at a master picture part, and also displaying a slave picture part without thinning out.
CONSTITUTION: An arrival video signal has its synchronizing signals separated by a synchronous separating circuit 11 and is supplied to a scanning signal generating circuit 14 which generates a double-speed horizontal synchronizing signal of frequency which is twice as high as that of the received horizontal synchronizing signal. The output digital video signal of an A/D converter 3 is written on a storage device 4 with the write signal from a control circuit 13. The time-base converted signal from the storage device 4 is processed by an interpolating circuit 15 to obtain a video signal increased in the number of scanning lines. A video signal for a slave image which is written on the storage device 23 for one vertical period in synchronization with a slave image video signal is read out in synchronization with a master image, sent to a D/A converter 6 for a slave image display period with the signal from the control circuit 15 through a switching circuit 5, and amplified by an output circuit 8 to a desired amplitude; and then a cathode-ray tube 10 is driven to obtain the slave image.
