ABSTRACT:
A magnetic video recording apparatus applicable to a video tape recorder or the like is designed integrally with a television camera. The apparatus has a video signal output unit for outputting first video signals, and a video signal recording unit for recording the first video signals outputting from the video signal output unit or second video signals obtained from an external video appliance. The video signal recording unit records the second video signals via correction means inserted for correcting the video signals to predetermined levels, but bypasses the correction means when recording the first video signals. Such bypass of the correction means eliminates any reduction of the signal-to-noise ratio that may otherwise be caused, hence preventing deterioration of the image quality in the reproduced video signals.
