Abstract
A method of switching between video signals in an image switching apparatus is provided, which apparatus has a switch for switching between the video signal supplied by a camera and the video signal supplied by a recording apparatus, and a circuit for processing the video signal coming from the recording apparatus. The processing circuit compares the video signal coming from the recording apparatus with the video signal supplied by the camera and then sets an operating mode on the basis of the comparison result. The output signal from the recording apparatus is a signal which comes from a tape in the replay mode. In the recording and stop modes, the signal entering the recorder is looped through to the output of the video recorder. The two signals have a correlation to each other. A conclusion can thus be drawn on whether the image switching apparatus should work in the replay mode or the recording mode by simple comparison.
