Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of connecting video camera means having a zoom function for shooting and recording moving images and still camera means having a zoom function for shooting and recording still images, or Relates to an integrally configured compound camera.

[0002]

2. Description of the Related Art While a conventional video camera for recording a moving image on a recording medium such as a magnetic tape is used for photographing, a still camera for recording a still image using a silver salt film or the like is desired. is there. In order to realize this, various compound cameras in which a video camera and a still camera are integrally configured have been devised. For example USP 3,546,37
No. 8 discloses the equivalent. But this kind of compound camera has a problem of what to do with the viewfinder of the camera and video.

A compound camera having only an optical finder is described in Japanese Patent Laid-Open No. 63-261330.

[0004]

[Problems to be Solved by the Invention] USP 3,546,378 is 1
The light passing through the two lenses is split by a mirror into the silver salt film and the image sensor side, and the viewfinder looks at the light to the film, so the zoom ratio of the silver salt system and the video system is the same.

Further, in Japanese Patent Laid-Open No. 63-261330, since the optical system of the silver salt system and the optical system of the video system are different, it is possible to construct a lens system having a zoom ratio suitable for each.
Since there is only one finder, it is necessary to match it with either lens system.

As described above, in the conventional example, since the silver halide camera and the video camera have different image circle sizes, a high magnification zoom system is suitable for a small format, but the silver salt camera has a large format. , A lens system that is too big is actually difficult. Therefore, if only one optical system is used, the optical system will be very insufficient for either one. In addition, even if the optical system is divided, there is no choice but to support either zoom ratio with one finder,
It becomes very unusable. It should be noted that the above publication does not describe the interlocking of zooms in detail.

The present invention has been made to solve the above-mentioned problems, and even if the zoom range of the video camera and the still camera is different, the interlocking range can be arbitrarily set, and the image recording by the video camera and the still camera can be performed. It is an object of the present invention to provide a compound camera that can be easily operated.

[0008]

Therefore, the compound camera according to the present invention has (1) a video camera means having a zoom function for recording moving image information on a first recording medium, and a zoom function. A still camera unit for recording still image information on a second recording medium; a setting unit for setting a zoom mode for linking the zoom function of the video camera unit and the zoom function of the still camera unit; A composite camera comprising control means for controlling and capable of simultaneous shooting and recording by a video camera means and a still camera means, wherein the zoom area of the video camera means and the zoom area of the still camera means are different, The other zoom can be automatically moved based on the setting by the zoom mode setting means in conjunction with the zoom movement operation of the still camera means. The object of the invention is to be achieved by a configuration characterized in that the angle of view of the start positions of both zooms that move in conjunction with each other can be set differently.

(2) In the above configuration, the angle of view at the start position of both zooms that move in an interlocking manner can be set differently, and the angle of view at the stop position of both zooms that move in an interlocking manner can also be set differently. Or each of the zoom areas that move in conjunction with each other is set to the OF of the device power supply.
In the F state, it is stored in the storage means of the control means so that the storage can be continued, or the zoom interlocking range of both of them can be set to the same, respectively, or the video. When the lens of the camera means or the lens of the still camera means is replaced, the state before the setting of the zoom interlocking is brought about, or when the zoom interlocking is set, the video camera means Alternatively, both zoom functions can be operated in conjunction with each other by the zoom operation means of the still camera means, or when the zoom interlock is set, the video camera means or the still camera means is turned on.
Even in the FF state, the means for photographing such as EVF, AF, AE, and zoom is configured to be turned on, or the setting of the zoom mode in which the zoom is linked. The setting operation to the means can be set by using a switching position provided by adding one to the dial for switching the camera / VTR mode of the video camera means, or the zoom. When the interlocking is set, zoom interlocking is possible in the setting mode when the video camera means is in the recording / reproducing state or when the still camera means is not exposing or film feeding. The above-described object is also achieved by the above-mentioned configurations and the above-described configurations.

[0010]

With the above configuration, for example, the interlocking of lenses with different zoom ratios is not simply adjusted to match the shorter one and only the same angle of view is operated, but the start position in which both zooms are operated is changed, By moving the other side twice with respect to the one side, the interlocking width can be arbitrarily selected instead of 1: 1 and the usability can be improved.

3. After the silver salt camera side stopped at B ₁ , the zoom of the video camera is left for Z ₁ minutes, so when you try to shoot a video there, you can press the video tele zoom switch 53 to zoom the silver salt camera. B at the tele end
Still stopped at ₁ , the video zooms up further towards D ₁ . Until F ₁ Pressing wide zoom switch 54 is moved to the wide side with a silver halide camera unit from F ₁ to zoom to the wide side only video camera.

4. Next, the zoom position of the video camera is F ₁
When the wide button 9 of the silver halide camera is pressed between the time between the position and D ₁ , the zoom of the video camera is quickly returned to F ₁ , and from there, both are zoomed to the wide side at the same time.

5. Even when the video camera is between the wide-side zoom positions E _{1 to} C ₁ , it is the same as when it was on the tele side, and only the video camera moves with the zoom button on the video side, and the video with the button on the silver halide camera side. It is configured to quickly bring the camera zoom to E ₁ .

6. That is, in the zoom switch whose zoom area has popped out, only the popped-out part moves, and when the zoom switch of the shorter camera is pressed, the same angle of view is quickly set.

FIG. 3 and FIG. 4 show the above-mentioned operation description as it is in the form of a flow chart.

Next, in the case where the zoom areas of the silver halide camera and the video camera are displaced from each other as shown in FIG. 5, the states and ideas described above shown in FIGS. It is the same, and when the short side zoom button is pressed, the long side is driven to the same place as the other side promptly. In the case of the configuration shown in FIG. 5, E _{2 to} B ₂ are the interlocking range.

(Second Embodiment) Next, a configuration and a setting method will be described, which is a feature of the second embodiment, in which the focal lengths are different and the interlocking widths are not the same.

In general, when the start button is pressed at any wide part of the silver halide camera or video camera, both are zoomed to end with any tele part of the silver halide camera or video camera.
If you push a button, only that area will move in tandem. Also, the fact that the interlocking widths are different means that if a silver salt camera 35-70 mm and a video camera 35-140 mm are set, the video camera changes the focal length twice as much as the zoom of the silver salt camera. That is, each time the silver halide camera shifts by 1 mm, the video camera shifts by 2 mm.

The zoom range described above is shown in FIG. The silver halide camera zoom position _{A 3:} 35mm, B 3: with respect to 70 mm,
It is shown that the video camera side is linked in the range of G ₃ : 30 mm and H ₃ : 120 mm. The interlocking range and the movement of the zoom out of the range are the same as the movements in the state where no setting is made, and the explanation thereof will be omitted.

The setting method will be described with reference to FIGS. 1 and 6 and the flowchart of FIG.

[0081]

As described above, according to the present invention,
Even if the zoom range of the video camera and the still camera is different, it is not necessary to operate both zooms by setting the interlocking range, and by linking without being bound by either short focal length. The still camera has a wide angle, and the video camera has a telephoto side, so that it is possible to shoot in accordance with the shooting style of each.

In birdwatching and the like, the subject is captured by super telephoto, but since the angle of view is extremely narrow in super telephoto, the subject may be missed by a slight blur. In such a case, the other side may have a wide angle. Since you are capturing the subject on that side, you can immediately find the position. This is especially true when using super-telephoto, but it can solve the problem that the subject goes somewhere immediately and that it is impossible to know whether the subject has shifted to the right, left, up, or down.

As described above, even if the video camera section and the still camera section have different zoom ranges, the interlocking range can be arbitrarily set, and effective shooting and recording can be easily performed by the video camera section and the still camera.
