Abstract

A composite camera apparatus employing a video camera device, a still camera device and a strobe device. The video camera device includes an electric circuit for picking up video data and processing the video data to record a video signal on a recording medium, such as a video tape. The electric circuit of the video camera apparatus includes means, associated with a strobe device and responsive to initiation of stroboscopic flashing, for controlling the electric circuit for recording the video signal so that a predetermined number of the video data picked-up at the occurrence of stroboscopic flashing, may not be reproduced when the video signal is reproduced by means of a VTR on a video monitor.

Claims

1. A composite camera apparatus comprising:

a video camera device for picking up a video image for recording a plurality of fields of video signals to be reproduced on a video monitor;

a still camera device for picking-up a still image for recording on a still image recording medium;

a strobo-flashing device cooperative with said still camera device for synchronous operation for emitting a strobo-flashing light in response to a still image pick-up operation of said still camera device; and

means, incorporated in said video camera device, for modifying video image data in a field of said video signal picked up at a timing of the strobo-flashing operation for avoidance of influence of high intensity light.

2. A composite camera apparatus as set forth in claim 1, wherein said video camera device comprises means for picking up a video image to produce a plurality of consecutive fields of video signals, means for processing said video signals and means for recording said video signals on a video tape, and said video image data modifying means is disposed between said video image picking up means and said video signal processing means.

3. A composite camera apparatus as set forth in claim 2, wherein said modifying means is active in synchronism with the operation of said strobo-flashing device for modifying the video image data of the field picked up when said stroboscopic light is emitted.

4. A composite camera apparatus as set forth in claim 3, wherein said modifying means replaces one field of video signal with a preset dummy signal.

5. A composite camera apparatus as set forth in claim 4, wherein said modifying means includes a memory for storing one field of video signal immediately preceding the field to be modified, and said preset dummy signal is one field of video signal stored in said memory.

6. A composite camera apparatus as set forth in claim 3, wherein said modifying means lowers gain level of one field of video signal to be modified.

7. A composite camera apparatus comprising:

a video camera device for picking up a video image for recording a plurality of fields of video signals to be reproduced on a video monitor;

a still camera device for picking up a still image for recording on a still image recording medium;

a strobo-flashing device cooperative with said still camera device for synchronous operation for emitting strobo-flashing light in response to still image pick-up operation of said still camera device; and

means, incorporated in said video camera device, for modifying video image data in a field of said video signal picked-up at a timing of the strobo-flashing operation by replacing the corresponding field of video signal with a preset dummy signal for avoidance of influence of high intensity light.

8. A composite camera apparatus as set forth in claim 7, wherein said video camera device comprises means for picking up a video image to produce a plurality of consecutive fields of video signal, means for processing said video signal and means for recording said video signal on a video tape, and said video image data modifying means is disposed between said video image picking-up means and said video signal processing means.

9. A composite camera apparatus as set forth in claim 8, wherein said modifying means is active in synchronism with operation of said strobo-flashing device for modifying the video image data of the field picked up when said stroboscopic light is emitted.

10. A composite camera apparatus as set forth in claim 9, wherein said modifying means comprises a constant voltage source for supplying a constant voltage as said dummy signal.

11. A composite camera apparatus as set forth in claim 9, wherein said modifying means comprises a memory storing said preset dummy signal.

12. A composite camera apparatus as set forth in claim 9, wherein said modifying means includes a memory for storing one field of video signal immediately preceding the field to be modified, and said preset dummy signal is one field of video signal stored in said memory.

13. A composite camera apparatus comprising:

a video camera device for picking up a video image for recording a plurality of fields of video signals to be reproduced on a video monitor;

a still camera device for picking up a still image for recording on a still image recording medium;

a strobo-flashing device cooperative with said still camera device for synchronous operation for emitting strobo-flashing light in response to still image pick-up operation of said still camera device; and

means, incorporated in said video camera device, for modifying video image data in a field of said video signal picked up at a timing of the strobo-flashing operation by lowering gain of the corresponding field of video signal for a given magnitude for avoidance of influence of high intensity light.

14. A composite camera apparatus as set forth in claim 13, wherein said video camera device comprises means for picking up a video image to produce a plurality of consecutive fields of a video signal, means for processing said video signal and means for recording said video signal on a video tape, and said video image data modifying means is disposed between said video image picking-up means and said video signal processing means.

15. A composite camera apparatus as set forth in claim 14, wherein said modifying means is active in synchronism with the operation of said strobo-flashing device for modifying the video image data of the field picked up when said stroboscopic light is emitted.
