Abstract

PURPOSE:To provide a photographing device capable of restricting the rewinding of a silver salt camera and the sound of automatic loading during the sound recording of a video camera. CONSTITUTION:When it is judged that the final frame is obtained in the step S104, an operation for rewinding the whole of a film is started (S106). The operation of the camera is stopped in a state where the whole of the film is rewound (S107) and a new film is loaded (S108). Before the automatic loading of the silver salt camera, it is confirmed whether video is in a sound recording state or not (S109) and when the video is not in the sound recording state, the automatic loading sound is never recorded so that the whole of the film is wound in a prewinding system, the first frame is figured out and return to an initial standby state is attained (S110). When the video is during the sound recording, the automatic loading is attained in a normal winding system, to make the automatic loading extremely little, two or three frames are wound and the operation is stopped to figure out the first frame (S111).

Description of the Related Art Conventionally, a video camera and a still camera which are integrally formed are disclosed in Japanese Patent Laid-Open No. 63-248285, and as described therein, unnecessary sound or noise is recorded during recording. It was thought to stop the operation of the silver halide camera unit so that it would not be done.

[0003]

However, there have conventionally been the following problems.

The advantage of the video camera in which the video camera and the silver halide camera are integrally formed is that the uncomfortable feeling of hanging two large things from the shoulder or the neck can be eliminated by integrating them, but video recording is possible. When I want to take a momentary image while taking a video, for example, when I'm taking a picture of a child at an athletic meet, not to mention the video, of course because the silver salt camera is not activated. Even if I wanted to take a moment with a silver salt photograph, it was impossible to shoot with that silver salt camera.

Although it is desired to take a continuous shot of a frame or the like, in the prior art disclosed in Japanese Patent Laid-Open No. 63-248285, the shutter can be released once for exposure. However, there was a drawback that only one goal was taken.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a photographing device for limiting the rewinding of a silver halide camera and the sound of auto-loading during recording by a video camera. To aim.

The focus motor 40a, the zoom motor 41a, and the diaphragm motor 42a are always in a driving state during photographing by the apparatus of this embodiment.

For film feeding of the silver halide camera, after filming one frame, the system controller 37 turns on the film feeding motor 39a via the camera control system 39 to wind the film. At this time, there is also a mode in which the operation is performed at a low speed so as to minimize the sound. However, since the time for one frame is short, it is possible to take a picture without feeling any discomfort even if the winding sound is heard. However, the rewinding of the film and the auto-loading are very uncomfortable when the video is reproduced because the motor is rotating for a very long time.

In the present embodiment, in order to shorten the time as much as possible, when the video is not driven, auto-loading is performed by the prewind to minimize rewinding, and when the film is replaced next time, the video is being driven. In this case, the normal wind mode is set to shorten the auto loading time as much as possible.

The operation of one embodiment of the present invention will be described below with reference to the flowchart of FIG. The following steps are abbreviated as "S".

First, a film is loaded in the camera and it is in a standby state (S101). Next, the camera is released (S102). As a result, distance measurement (A
F), photometry (AE) is performed, and the shutter is opened and closed (S10).
3).

Then, it is determined whether or not the photographed frame is the last frame (S104), and if not, S10.
Go to 5 and feed one frame (S105), then S10 again.
It returns to 1 and becomes a standby state.

If it is determined in S104 that the film is the last frame, the film rewinding operation is started (S10).
6). Then, the operation of the camera is stopped while the film is completely rewound (S107), and a new film is loaded (S108).

Next, it is confirmed whether or not the video is in a recording state before the silver halide camera is automatically loaded (S10).
9) If the video is not in the recording state, no auto-loading sound is recorded. Therefore, all the film is wound by the prewind method to index the first frame, and the initial standby state is returned (S110).

Further, when the video is being recorded, autoloading is performed by the normal wind method in order to reduce the autoloading noise as much as possible, and the first frame is indexed by winding and stopping two or three sheets (S111). ).

[0031]

As described above, according to the first and second aspects of the present invention, when the next film is inserted while the film is rewound, the automatic loading is performed by the normal wind while the video is being recorded. , The following effects can be obtained by auto-loading with prewind when the video is not driven. That is, in the case of taking the first film, by inserting the film before taking a picture, the rewinding time becomes very short because the auto-loading is performed by the prewind, and when the film is exchanged during driving, ,
By minimizing the autoloading sound in the normal wind, it is effective in reducing the strange sound and noise when the video is played back.
