Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup apparatus in which a video camera and a silver salt camera are integrally formed, and at the same time, the video camera and the silver salt camera are operable.

[0002]

2. Description of the Related Art Conventionally, an integrated video and camera is disclosed in JP-A-63-248285, and as described in this publication, 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. Because I do not activate the silver salt camera inside, when I want to take a momentary image while shooting a video, for example when shooting a child's smile at an athletic meet, let's not only watch the video but also the state around the goal Even if you want to take a moment with a salt photograph, shooting with that still camera has never been possible.

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 in order to solve the above problems, and provides a photographing device for preventing unnecessary sound, which is generated by rewinding a silver salt film, from being recorded for a long time during photographing by a video camera. The purpose is to provide.

[0007]

In order to achieve the above-mentioned object, the photographing apparatus of the present invention comprises, in claim 1, a video camera for recording image information on a recording medium and a silver salt camera, which are integrated with each other. During recording with the camera, in a shooting device configured to allow the exposure operation of the silver salt camera and film winding, the video camera section is recording the transition to the automatic rewind mode after the completion of all frame exposure of the silver salt film. Has a prohibition mode, and has a mode for canceling the prohibition state by the prohibition mode in claim 2, and further has a prohibition state by the prohibition mode in claim 3. Sometimes EVF
The (electronic viewfinder) is provided with means for displaying that state.

[0008]

According to the first aspect of the present invention, the rewinding sound is recorded during the long rewinding time by prohibiting the rewinding of the silver salt film when the video and the camera are simultaneously shooting. Therefore, the image is not discomforted.

According to the second aspect, it is possible to take a large number of silver salt films at the same time by providing a mode in which the prohibition is released in case the silver salt film is replaced inevitably. Further, according to the third aspect, the EVF is provided with means for displaying the state when the prohibition mode is in the prohibition state, so that the operator can know.

The zoom control can be set by the user using the zoom button 19 while looking through the viewfinder 4. In the shutter control, by rotating the shutter button 18, the user can select various photography modes such as aperture priority AE, shutter speed priority AE, and program AE. Further, based on the result of photometry by the solid-state image sensor 33, the shutter speed is controlled by the shutter control unit 44, and the aperture control is performed by the aperture control unit 42 to perform a predetermined exposure on the photographic film surface. At this time, when the aperture control is performed, the illuminance on the image forming surface of the solid-state image sensor 33 changes, so the image sensor control unit 43 controls the gain of the solid-state image sensor 33. Reference numeral 51 is an EVF drive control system, and 52 is a display.

Next, in each of the embodiments shown in FIG. 10, the drive timing of a mechanical active element such as a video motor or solenoid during video shooting and the drive timing of a mechanical active element such as a motor or solenoid during photo shooting.

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.

In addition, in the film feeding of the silver salt film, after filming one frame, the system controller 37 turns on the film feeding motor 39a through 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 silver halide film is very uncomfortable when the video is being played because the motor is rotating for a very long time. Therefore, rewinding is configured to be prohibited during video recording after all frames have been shot.

Further, as shown in FIG. 4, there is a rewind release mode around the shutter button / mode dial 18, and by rotating the shutter button / mode dial 18 to 18f, the rewind prohibition described above can be achieved. It is released and automatic rewinding starts. After the rewinding is completed, the film can be taken out and a new cartridge can be loaded to take another picture.

At this time, it is displayed in the viewfinder in the form of a patrone unlike the tape in the sense that it is distinguished from the remaining tape amount of the video. The EVF has a control system 51 and a display 52. 5
3 has a patrone mark to indicate that the silver halide film has finished all frames. It is preferable that this mark is a Patrone mark in order to make sure that the silver salt film is gone.

FIG. 12 is a flow chart showing the operation of the first embodiment of the present invention, and the operation of the embodiment will be described according to this flow. In addition, in the flow of FIG. 12, each step is abbreviated as “S”.

First, a film is loaded in the silver halide camera section of the photographing device and is in a standby state (S101). Next, the silver halide camera is released (S102). Next, A
Exposure operations of F (distance measurement), AE (photometry), and shutter opening / closing are performed (S103). Then, it is determined whether or not the photographed frame is the final frame (S104). If the frame is not the final frame, one frame is fed (S105), and the process returns to S101 again to enter the standby state.

If it is determined in S104 that the frame is the last frame, it is determined whether or not the video camera unit is currently recording (S1).
06) If the recording is in progress, the rewinding of the silver salt film is stopped (S109).

If it is determined in S106 that the video camera unit is not recording, the rewinding operation of the silver salt film is started (S107), and the rewinding of the silver salt camera unit is stopped at the end of the film (S108). .

Next, in S109, after the rewinding of the silver halide camera is stopped because the video is being recorded, it is judged whether or not the rewinding prohibition release (the dial 18 of FIG. 4 is at the position 18f) is turned on. (S110), if canceled, S107
At step S109, the rewinding operation is started, and if the prohibition is not released, the stop of the silver halide camera in S109 is further continued.

FIG. 13 shows a second embodiment of the present invention, and since it is almost the same as FIG. 12, a description thereof will be omitted. The difference is that S1 when the silver halide camera is stopped.
In the case of 09, it is the operation of displaying on the EVF that the rewinding of the silver salt film is prohibited (S109-2).
