IPC: H04N5/45
Filed: 1993-07-26
Abstract: PURPOSE:To prevent an image for master picture and an image for slave picture from being overlapped each other and to prevent the image for master picture from being hidden by a slave picture. CONSTITUTION:When a PIP circuit 28 is not turned on, the aspect ratio of the image for master picture inputted through a switch 16 is converted from 4:3 to 16:9 by an aspect conversion circuit 26 and displayed on a CRT 40. On the other hand, when the PIP circuit 28 is turned on by controlling a remote controller 22, the image for slave picture inputted through a switch 30 is mixed with the image for master picture. At such a time, the aspect ratio of the image for master picture is returned to 4:3 by the aspect conversion circuit 26 and moved to the left side of the CRT 40. Then, the image for slave picture is displayed at the lower right part of the CRT.
