Abstract

PURPOSE:To provide a video signal display device for automatically switching a television screen to a dual picture mode when a video equipment is reproduced at the time of a television reception mode or for recovering the television reception mode from the dual picture mode when the video equipment is stopped. CONSTITUTION:When the video signal of the video equipment is inputted to an input terminal 8a, the detection signal of 'H' or 'L' is extracted by an operation detection part 1 for detecting the state of the video equipment, and a key scan signal is outputted from a key output port part 5 of a microcomputer processing part 4. Then, the scan signal is fetched into a key input port part 7, a dual picture control signal is outputted from an output terminal 8c and the picture mode of a television is switched by a mode switching part 6.

This figure shows a configuration diagram in which, when a detection signal is detected by the detection circuit diagram in the television reception mode, the mode is automatically switched to the two-screen mode. A video device is connected to the video signal input terminal 8b, the operation detector 1 detects an H signal and inputs it to the base of the transistor 2, and the transistor 2 and the transistor 3 are turned on. A scan signal is output from the key output port unit 5 of the microcomputer processing unit 4, the scan signal is taken into the key input port unit 7 via the base and emitter of the transistor 3, and a dual screen control signal is output from the mode switching unit 6 Output from 8c. When no signal is output from the motion detector 1, the signal is not taken into the key input port unit 7, so that the mode is not switched. According to the present embodiment, it is possible to automatically switch the screen mode when displaying the output image of the video device.
