Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing device in which a video camera and a camera are integrated.

[0002]

2. Description of the Related Art Conventionally, a user has a video camera and a photographic device separately and uses them separately. Alternatively, there have been proposed ones that are configured in the same housing in a grip of a video camera or in parallel with each other in the camera, or ones in which a camera can be attached to an accessory shoe of the video camera.

[0003]

However, when the above-mentioned conventional video camera and photographic device are used, there are the following drawbacks. Images taken with video and images taken with a camera were independent. A dedicated video printer was required to make a hard copy of the video image. In video shooting, the video tape was rewound at the shooting site, and the composition and the like could be confirmed immediately, but in photography, it was necessary to develop it, and the composition could not be confirmed immediately. The timing of the operation of the motor, solenoid, etc. used for each operation of the video camera and the timing of the operation of the motor, solenoid, etc. used for each operation of the camera overlap, and the electric power at that time increases and the power supply also increases.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain an ideal photographing device having a simple structure in which a video camera and a photographic device are integrated, with no unnecessary operation. To do.

[0005]

In order to achieve the above-mentioned object, the photographing apparatus of the present invention is, in claim 1, an image input means, and a first recording means and a second recording means which share the image input means. An image pickup apparatus having the same recording means as that in the same housing, and a display means for displaying the image recorded by the first recording means, and the image displayed by the display means is recorded by the second recording means. The display image recorded by the first recording unit and the image of the image input unit are combined and recorded by the second recording unit. In the second, the optical means for allocating the image from the image input means to the first recording means and the second recording means, and the display image recorded by the first recording means are secondly recorded.
It is also used as an optical means for leading to the recording means. Further, in claim 4, the image from the image input means is distributed to a plurality of recording means by an optical dividing means having a moving mechanism. In claim 5, the image is stored while the optical dividing means is moving. In addition, it has a recording means for substituting the information on the previous screen. Further, in claim 6,
At least one of the recording means records information about the recording state of the other recording means. Further, according to claim 7, when the mechanical operation of the first recording means and the mechanical operation of the second recording means simultaneously overlap with each other except the mechanical operation of the shared image input means, the second operation is performed. Of the first recording means when the mechanical operation of the second recording means is stopped in the middle of the second recording means. After the operation is stopped, the mechanical operation of the second recording unit is restored, and the drive source of the mechanical operation of the first recording unit and the mechanical operation of the second recording unit are shared. It is a thing.

[0006]
