Detachable unit electronic camera
First Claim
1. A detachable unit electronic camera system 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 for producing a luminance signal and color difference signals in response to an output signal from the camera means;
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 is based on the output signal from the camera means, and magnetic reproducing means for reading the 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 the reproduced 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 photographic unit, the record/playback unit and the picture monitor unit being detachable units which can be selectively coupled together by cooperating coupling means provided in each unit, each of said units having at least two coupling means, each of said coupling means being provided for coupling to the associated coupling means of a different one of the other units connectable therewith;
control means provided in only one of said units for selectively activating the units connected therewith to operate to record signals when in a first state and to play back recorded signals when in a second state.

Abstract
A detachable unit electronic camera includes three detachable units, namely, a photographing unit, a record/playback unit and a picture monitor unit. The photographing unit has the function to convert an output signal from a camera into a luminance signal and color difference signals. The record/playback unit has the function of magnetically recording an output signal from the photographing unit on a magnetic disc and also the function of reading a signal which is previously recorded on the magnetic disc. The picture monitor unit has the function of displaying a picture in response to an output signal from the photographing unit or a signal which is reproduced from the record/playback unit.
