Abstract

A camera head having an image pickup member, a taking lens system for forming an image of an object on the image pickup member and a shutter means is selectively mounted on a still camera body and a motion picture camera body. The still camera body includes a recording/controlling section adapted to record output signals from the image pickup member on a recording medium as a still picture, while the motion picture camera body includes a recording/controlling section adapted to record output signals from the image pickup member on a recording medium as a motion picture.

Claims

1. An electronic camera system, comprising:

a camera head having a taking lens system for forming an image of an object to be shot, image pickup means for converting an optical image of said object into an electrical signal representing said object, shutter means, and first and second terminals mounted on said camera head and coupled to said image pickup means;

a still picture camera body for taking still picture having a recording/controlling section adapted to be connected to the image pickup member to record output signals therefrom on a recording medium as a still picture, said still picture camera body having terminals mounted therein and coupled to said still picture recording/controlling section for mating with said camera head mounted terminals; and

a motion picture camera body for taking a motion picture having a recording/controlling section adapted to be connected to the pickup member to record output signals therefrom on a recording medium as a motion picture, said motion picture camera body having terminals mounted therein and coupled to said motion picture recording/controlling section for mating with said camera head mounted terminals;

said camera head being selectively removably mountable on the still picture camera body and the motion picture camera body such that the camera head mounted electrical terminals are in electrical contact with the corresponding terminals on the camera body to which the camera head is mounted.

2. An electronic camera as defined in claim 1, wherein said recording/controlling section in the still picture camera body includes a recording section, a signal processing section and a synchronizing signal generator, said signal processing section including a quantizer the quantization bit number of which is large enough to obtain an image of high quality, and being able to process a large amount of data for a frame, said synchronizing signal generator being adapted to deliver a synchronizing signal both to the signal processing section and the image pickup member in said camera head when the camera head is mounted on the still picture camera body.

3. An electronic camera system as defined in claim 2, wherein said still picture camera body includes a first electrical terminal for coupling with said first camera body mounted terminal to establish an electrical connection between the image pickup member in the camera head and the synchronizing signal generator in the camera body when the camera head is mounted thereon, and a second electrical terminal for coupling with said second camera head mounted terminal to establish an electrical connection between the image pickup member and the signal processing section when the camera head is mounted on the still picture camera body, the output signals from image pick member being read out through the second camera head and camera body terminals to the signal processing section under the control of the output of the synchronizing signal generator.

4. An electronic camera system as defined in claim 2 or claim 3, wherein said recording/controlling section in the motion picture camera body includes a recording section, a signal processing section and a synchronizing signal generator, said signal processing section including a quantizer the quantization bit number of which is smaller than that of the quantizer in the still picture camera body, said synchronizing signal generator being adapted to deliver a synchronizing signal both to the signal processing section and the image pickup member in said camera head when the camera head is mounted on the motion picture camera body.

5. An electronic camera system as defined in claim 4, wherein said motion picture camera body includes a third electrical terminal for coupling with said first camera head mounted terminal to establish an electrical connection between the image pickup member in the camera head and the synchronizing signal generator in the motion picture camera body when the camera head is mounted thereon, and a fourth electrical terminal for coupling with said second camera head mounted terminal to establish an electrical connection between the image pickup member and the signal processing section when the camera head is mounted on the motion picture camera body, the output signals from the image pickup member being read out through said second camera head and fourth camera body terminals to the signal processing section under the control of the output of the synchronizing signal generator.

6. An electronic camera system as defined in claim 5, wherein said recording/controlling section in the motion picture camera body includes means for reading out the output signals from the image pickup member in an interlaced fashion.

7. An electronic camera system as defined in claim 5, wherein said motion picture camera body comprises first and second halves disconnectably connected with each other by means of a cable, said synchronizing signal generator being in the first half while said recording section is in the second half, both terminals being on the first half and electrically connected to the recording section by way of the cable.
