Claims
- 1. An electronic still video camera having an electro-developing recording medium, comprising:
- a photographing optical system that forms an optical image on said electro-developing recording medium to record and develop said optical image therein;
- an image-sensing device that optically senses and obtains image data from said image recorded on said electro-developing recording medium;
- a transferring device that transfers said sensed and obtained image data to an external device;
- a power source system that includes an internal power source that electrically energizes the electronic still video camera, a detecting circuit that detects a connection of an external power source to said power source system, and a switching circuit that switches said electrical energization of the electronic still video camera by said internal power source to an electrical energization of the electronic still video camera by said external power source when said detecting circuit detects said connection of said external power source to said power source system; and
- a disabling device that disables at least one of formation of said optical image on said electro-developing recording medium and said sensing and obtaining of said image data from said recorded image of said electro-developing recording medium when said transfer of said sensed and obtained image data to said external device is to occur and said connection of said external power source to said power source system is not detected by said detecting circuit.
- 2. The electronic still video camera of claim 1, further comprising:
- an image-erasing device that erases said recorded image from said electro-developing recording medium,
- said disabling device disabling said erasing of said recorded image from said electro-developing recording medium when said connection of said external power source to said power source system is not detected by said detecting circuit.
- 3. An electronic still video camera as set forth in claim 1, wherein said electro-developing recording medium comprises an electrostatic information recording medium and an electric charge keeping medium.
- 4. An electronic still video camera as set forth in claim 3, wherein said electrostatic information recording medium includes a photoconducting layer and an inorganic oxide material layer, and said electric charge keeping medium includes a liquid crystal display.
- 5. An electronic still video camera as set forth in claim 4, wherein said liquid crystal display comprises a memory type liquid crystal display.
- 6. The electronic still video camera of claim 1, further comprising a storing device that stores said image data sensed from said recorded image of said electro-developing recording medium by said image-sensing device.
- 7. The electronic still video camera of claim 6, wherein said storing device comprises a recording device and a second recording medium, said second recording medium being loadable in and driveable by said recording device, said second recording medium storing said image data when driven by said recording device.
- 8. An electronic still video camera as set forth in claim 1, wherein said external device comprises an image data processor device for processing the transferred image data.
- 9. An electronic still video camera as set forth in claim 1, wherein said external device comprises a monitor device for reproducing the optical image on the basis of the transferred image data.
