Detachable unit electronic camera

An electronic camera capable of recording and playback operation, comprising:

• a photographing unit including camera means which converts an image of an object being photographed which is focussed by a photographing optical system into an electrical signal, and a signal processing circuit responsive to an output signal from the camera means for producing a luminance signal and color difference signals;
• a record/playback unit including image recording means responsive to an output from the signal processing circuit for recording a video signal, which is based on the output signal from the signal processing circuit, on a magnetic disc, and magnetic reproducing means which reads a signal which is previously recorded on the magnetic disc;
• and a picture monitor unit including a reproduced signal processing circuit responsive to a signal reproduced by the magnetic reproducing means for producing a reproduced luminance signal and reproduced color difference signals, an encoder responsive to an output from one of the circuits including the reproduced signal processing circuit and the signal processing circuit for producing a composite color video signal, and a display for displaying a picture based on an output signal from the encoder;
• the photographing unit, the record/playback unit and the picture monitor unit being physically coupled together by cooperating releasable coupling means provided on each unit.

An electronic camera for devoted use in recording, comprising:

• a photographing unit including camera means for converting a photographic image of an object being photographed which is focussed by a photographing optical system into an electrical signal, and a signal processing circuit for producing a luminance signal and color difference signals responsive to an output signal from he camera means;
• and
• a record/playback unit including image recording means responsive to an output signal from the signal processing circuit for magnetically recording on a magnetic disc a video signal which corresponds to the output signal and magnetic reproducing means for reading a signal previously recorded on the magnetic disc,
• the photographing unit and the record/playback unit being physically coupled together by said coupling means to permit the image being photographed to be monitored by an optical viewfinder, means in one of said units for controlling operation of both of said units when the units are connected by said coupling means.
