DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup apparatus having a recording section and the like.

[0002]

2. Description of the Related Art FIG. 11 is a schematic view of a conventional recorder-integrated video camera. An image pickup section 1 includes a lens, an image pickup element, an image pickup system signal processing circuit, and the like. A processing circuit, a chassis, a head, a drum and the like for loading and recording / reproducing a video tape, and a video tape 3 is detachable from the recording unit 2;
The display unit 4 allows a photographer to view the video captured by the image capturing unit 1 and information related to the capturing, and further, the video reproduced and the related information by the recording unit 2.

FIG. 12 shows another example of a conventional display screen of the display unit 4. A recording message 6 indicating that the operation state of the recording unit 2 is being recorded is shown on the display screen 5. (REC) and a tape remaining amount message 7 (eg, 5MIN) indicating the remaining amount of the video tape 3 being recorded.

Conventionally, at the time of photographing, a video signal formed by the image pickup unit 1 is sent to a recording unit 2, where it is subjected to appropriate signal processing and recorded on a video tape 3. Further, the recording unit 2 adds a recording message 6 and a tape remaining amount message 7 to the video signal from the imaging unit 1 and sends it to the display unit 4. The display unit 4 is a recording unit 3
Displays the video signal sent from the
You can shoot while watching the remaining tape message 7
During recording, it is possible to know that the remaining amount of the tape has run out, and at the time of reproduction, the recording unit 2 can reproduce the video signal recorded on the video tape 3 and output it to the display unit 4. is there.

[0005]

However, in the above-mentioned conventional example, the photographer can know the tape remaining amount by the tape remaining amount message 7 during the photographing, but when the remaining amount of the tape is exhausted. In order to continue shooting, work and time such as re-attaching a new video tape or rewinding the tape are necessary, and if you are unlucky you will not be able to record important scenes for the photographer. There is a problem that arises.

The present invention has been made in view of the above points. In the case where the photographer can take a picture while looking at the overwrite mode message and the remaining hard disk message on the display unit and the free space of the hard disk is likely to be exhausted. , Replace with a new hard disk, overwrite the old data area, overwrite the unprotected old data area, or insert a memory card instead of videotape and shoot while watching the memory card remaining message If the memory card is running out of space, replace it with a new memory card,
It is an object of the present invention to provide an imaging device capable of selecting whether to overwrite an old unprotected data area.
