To provide a video signal processing apparatus capable of processing a video signal without fail even in a slow shutter mode.

The video signal processing apparatus is provided with: an imaging means A; a recording signal processing means C; a memory D; a video signal selection means E; and an inhibit signal output means H, when an operating mode setting means G sets the slow shutter mode, the inhibit signal output means H controls the recording signal processing means C to perform compression encoding for a period when an output signal of the imaging means A is not written in the memory D so as to eliminate a defect of the processing to be completed in one field, or one frame, or one recording track period from being failed.
