Abstract

PURPOSE:To perform camera photographing simultaneously while video photographing is being performed by the same device and to use only a camera when it is desired to photograph a picture and only a video camera recorder when it is desired to photograph a video separately. CONSTITUTION:The video can be irradiated on film 7 by switching an optical path only when the shutter 5 of the camera is pressed even while the video photographing is being performed considering that a long time is required for the video photographing and the camera photographing can be performed in a moment. Since the optical path is returned to a video side in a moment, influence is scarcely given on a video image. Also, it is desired to use the device only as the camera or the video camera recorder separately. Therefore, a lens system 1, a video system 3, and a camera system 2 are composed loadably/ unloadably freely, and they are combined corresponding to the purpose.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to devices in both fields of photography for recording video as a still image and video camera recorder for recording as a moving image.

[0002]

2. Description of the Related Art Conventionally, a camera for recording an image as a still image records an image incident from a lens system by exposing it to a silver salt film. Since the grains of the silver salt film are very small, an image with good resolution can be obtained when printed on photographic paper.
On the other hand, a video camera recorder converts an image incident from a lens system into an electric signal by an image pickup device such as an image pickup tube or a CCD device and records it on a magnetic tape or a magnetic disk. Further, the electric signal may be converted into an optical signal of a laser again and digitally recorded on a tape or a disk. However, although a moving image can be recorded, the number of pixels of the image sensor is much smaller than that of a silver salt film. Therefore, the resolution of the image is poor, and even if a still image is printed out by a video printer or the like, a clear and beautiful image like a camera cannot be obtained.

[0003]

Even when a moving image is taken with a conventional video camera recorder, a silver halide film camera is often used to bring a still image to a still image more beautifully. . Otherwise, I have to give up one.

It is an object of the present invention to enable taking a picture and a video at the same time with the same device during video shooting.

[0005]

[Means for Solving the Problem] Considering that the video shooting time is long and continuous, and the photo shooting is momentary, the optical path is switched only when the shutter of the camera is released to shoot the image on the film even during the video shooting. To do. Since the optical path returns to the video side instantly, it hardly affects the video image. In some cases, it may be desired to use it alone as a camera or as a video camera recorder. Therefore, the lens system, the video system, and the photographic system can be attached and detached, respectively, and combined according to the use.

FIG. 1 shows a camera with a video recorder according to the present invention.
As shown in the elevation view, it is composed of a lens system 1, a camera system 2 and a video system 3. The lens system 1 can use various methods conventionally used in a photographic apparatus. A typical example thereof is shown in FIG. The camera system 2 switches the image coming in from the lens system 1 to the shutter 5 direction or the finder 8 direction by the rotating mirror 4 as in the conventional single-lens reflex camera. A silver salt film 7 is set after the shutter 5. Other components include a diaphragm 8, a film winding device 9, and an outer case 10.
In the video system 3, the image coming from the finder 6 of the camera system 2 is color-separated by the color separation block 11, and the CCD 1
Entered in 2. Other electric circuit board 13, electronic viewfinder 14, tape drive device 15, rotary drum 1
6 and a hide exterior case 17 and the like.

[0007]

In the camera with a video recorder of the present invention shown in FIG. 1, the light entering the lens system 1 is reflected by the rotating mirror 4. Then, it hits the fixed mirror 18 and is reflected to reach the finder 6. The light emitted from the finder 6 enters the video system 3 and passes through the correction block 19. The correction block 19 corrects the lens system 1 designed to be suitable for the camera system 2 to be suitable for the video system 3.
The corrected light enters the next color separation block 11 and is separated into the three primary colors and enters the CCD 12. In the CCD 12, the light is converted into electrons and becomes an electric signal and is sent to the electric circuit board 13. After that, it is no different from the conventional video camera recorder,
The cassette tape 20 is wound around the rotating drum 16 by the tape driving device 15 and records an electric signal. In this case, the subject can be tracked by looking through the electronic viewfinder 14. While shooting a video, press the shutter button 21 if there is a scene that you want to leave as a photo. Then, the rotary mirror 4 instantaneously rises, the light advances toward the camera system 2, and at the same time, the shutter 5 opens, and an image is printed on the silver salt film 7. However, since the rotating mirror 4 immediately returns to the original position, it hardly affects the video image,
You can continue shooting video.

Next, when only the photographic function is desired to be used, the video fixture 22 is removed, and the lens system 1 and the camera system 2 are combined. Although not shown in the figure, it is a conventional single-lens reflex camera itself, and its usage and operation are exactly the same as those of the conventional single-lens reflex camera. That is, shutter button 2
Pressing 1 raises the rotating mirror 4 and simultaneously releases the shutter 5.
The image entered from the lens system 1 is printed on the silver salt film 7.

If it is desired to use only the video camera recorder function, the lens fixture 23 is opened to remove the lens system 1 from the camera system 2 as shown in an elevation view in FIG. Attach directly to the attachment 24. Then, the light entering the lens system 1 directly enters the correction block 19 and becomes a video camera recorder which can be processed by the video system 3.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a video recorder equipped with a video recorder according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment of the lens system 1.
Is designed to form an optimum image for the camera system 2. The correction block 19 corrects the light so as to form an optimum image for the video system 3. Other configurations have already been described in section [0006]. However, if the color separation block 11 is of the stripe filter type, even if the lens system 1 is optimal for the camera system 2,
It can also be used for the video system 3 without the correction block 19.

FIG. 3 is an elevational view of the second embodiment. In the camera system 2, a correction block 19, a color separation block 11 and a color separation block C are provided.
It incorporates a CD12. The fixed mirror 18 is not attached. By doing so, the size can be reduced because the fixed mirror 18 is not provided. However, the video system 3 alone does not function. Therefore, when it is used as a single-lens reflex camera, the electronic viewfinder 14 is used to follow the subject. Or look into the viewfinder 26 with another lens 25.

FIG. 4 is a plan view of the third embodiment, in which the positional relationship between the camera system 2 and the video system 3 with respect to the lens system 1 is reversed. That is, the rotary mirror 4 is normally raised. Immediately behind is a correction block 19, a color separation block 11, and a CCD 12. The camera system 2 is next to the rotary mirror 4, and is followed by the shutter 5, the diaphragm 8, and the silver salt film 7 attached to the film winding device 9. By the way, in this embodiment, the direct light of the light entering the lens system 1 enters the video system 3. Therefore, the reflected light reflected by the rotating mirror 4 enters the photographic system 2. Further, as in the first embodiment, the video system 3 and the camera system 2 can be attached and detached by the video fixture 22, and can be used for the photographic function alone. Further, since the lens system 1 and the video system 3 can be attached and detached by the lens fixture 23, the video system can be used alone.

Although not shown in the drawing, the video system 3
CCD 12 is changed to an image pickup tube, cassette tape 2
Even if 0 is changed to a digital disc, the idea of the configuration of the present invention is the same. Further, the exterior case 10 and the video exterior case 17 are integrated, and the camera system 2 and the video system 3 are integrated.
Even if there is no clear distinction, if the optical path after leaving the lens system 1 branches to the camera system 2 and the video system 3, it does not depart from the gist of the present invention.

[0015]

The camera with a video recorder of the present invention can be used as a camera for printing an image on the silver salt film 7 as long as the shutter button 21 is pressed during video recording. Moreover, since the shutter time is only a moment, it hardly affects the recording of the video. By the way, the image quality printed out from the silver halide film 7 is much more beautiful than the image quality printed out from the video, and thus has a high storage value. Therefore, the photographer with a video recorder of the present invention is the most effective device for taking a video and taking a photograph. Further, by allowing the lens system 1, the camera system 2 and the video system 3 to be attached / detached, the lens system 1, the camera system 2 and the video system 3 can be used independently, for example, only as a camera or as a video camera recorder.
