Abstract

PURPOSE: To adapt that a portable television camera device utilizes its video signal to be able to output automatically a start-stop trigger signal to the video-tape recorder.
CONSTITUTION: The camera tube output 5 of a portable television device is amplified and processed by a preamplifier circuit 6, video amplifier and an image processing circuits and a video signal 8 is output. This video signal 8 is amplified by a video output amplifier circuit 9, and output from a terminal 10, at the same time, is shaped and amplified by circuits 11, 12, and DC components 13 is taken out. A detector circuit 14, if a level of the DC components 13 becomes not less than a specified value, outputs H logical signal. This operates a driving circuit 2, causes the start trigger signal 3 to start the video tape recorder to output, then, causes a tally lamp 4 to light up. When the DC components is lowered, the detector circuit outputs L logical signal, and the driving circuit 2 becomes non-operation by the L logic signal, and outputs the stop trigger signal 3 to stop the video tape recorder.
