BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera with a still camera in which a video camera for converting an image into an image signal and recording the image and a still camera for recording the image on a film are integrated.

[0002]

As is well known, a video camera forms an image on a CCD sensor, processes a signal output from the CCD sensor to form an image signal, and records the image signal on a magnetic tape. It is used mainly for capturing moving images.

Further, the still camera forms an image on a film, exposes a photosensitive agent to the image, and records the image on the film, so that a high-quality still image can be obtained.

[0004]

By the way, there is a case where it is desired to leave one image out of a series of images as a still image while capturing an image with a video camera.
In this case, since it is impossible to operate the still camera while operating the video camera to take an image, for example, a desired image is extracted from a series of images once taken by the video camera, and this image is taken out. I had no choice but to print on the recording paper. However, the quality of the image thus printed was poor and the desired result could not be obtained.

Therefore, an object of the present invention is to obtain a video camera with a still camera capable of taking an image with a still camera during the taking of the image with the video camera.

[0006]

In order to solve the above-mentioned problems, according to the present invention, the lens is inserted into or removed from the rear of the lens, and when it is inserted into the lens, the light from the lens is totally reflected and bent. An image is formed by the image sensor at one of the reflection mirror, the first focal position of the lens when the total reflection mirror is removed, and the second focal position of the lens when the total reflection mirror is inserted. , A video camera for recording this image on a recording medium, a still camera for capturing an image formed at the other of the first and second focal positions with a film, and an image for storing the image captured by the image sensor of the video camera Just insert or remove the memory and the total reflection mirror, and immediately before the image is taken with the film of the still camera, the image taken by the image sensor of the video camera is displayed. Mori to be stored, while the imaging by film of the still camera is being performed, and a control means for recording on a recording medium of the video camera by repeating the image in the image memory.

[0007]

According to this invention, the control means inserts or removes the total reflection mirror and stores the image picked up by the image pickup device of the video camera in the image memory immediately before the image pickup by the film of the still camera. While the image is taken by the still camera, the image in the image memory is repeatedly recorded on the recording medium of the video camera.
That is, the image immediately before the start of image capturing by the still camera is stored in the image memory, and when the image is no longer formed on the image sensor of the video camera when the total reflection mirror is inserted or removed, the image in the image memory is not formed. Is repeatedly recorded on the recording medium of the video camera. As a result, the image to be recorded on the recording medium of the video camera does not drop out while the image is picked up by the still camera.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 schematically shows an embodiment of a video camera with a still camera according to the present invention. In FIG. 1, a lens 2 is attached to a video camera 1, and a CCD sensor 3 which is an image pickup device is arranged behind the lens 2. The light from the lens 2 enters the CCD sensor 3, and an image is formed here.
In response to this, a signal is output from the CCD sensor 3, and an image signal is formed by processing this signal.

A mirror 4 is axially supported in the video camera 1, and the mirror 4 rotates about its axis 5 up to a stopper 6.

A still camera 7 is attached to the bottom of the video camera 1. The still camera 7 includes a shutter 8 and a film 9 arranged below the shutter 8.

When the mirror 4 in the video camera 1 is rotated up to the stopper 6, the lens 2 is moved as shown in FIG.
The optical path from to CCD sensor 3 is bent at a right angle downward in the middle. At this time, when the shutter 8 is opened, an image is formed on the film 9, and the still camera 7
The image is picked up. That is, the imaging by the video camera 1 is interrupted, and instead, the imaging by the still camera 7 is performed.

FIG. 3 is a block diagram showing the configuration of the video camera of this embodiment. In the figure, the image processing unit 1
1 receives a signal from the CCD sensor 3, processes this signal to form an image signal, and records the image signal in the recording unit 12
Output to. When receiving the image signal, the recording unit 12 records the image signal on a magnetic tape (not shown). Such processing is continuously performed, and thereby a moving image is captured.

The image memory 13 is for temporarily storing an image signal representing one image as data.

The shutter control unit 14 controls the operation of the motor 16 pivotally supporting the mirror 4 and the shutter mechanism 17 for opening and closing the shutter 8 (shown in FIG. 1) in response to the depression of the shutter button 15. belongs to.

Now, in such a structure, an operation procedure when the shutter button 15 is pressed will be described below.
Note that, here, it is assumed that the CCD sensor 3, the image processing unit 11, and the recording unit 12 are capturing images, that is, capturing a moving image.

First, when the shutter button 15 is pressed, in response to this, the shutter control section 14 notifies the image processing section 11 that the shutter button 15 has been pressed. Upon receiving the notification to that effect, the image processing unit 11 causes the image memory 13 to store, as data, the image signal indicating the image first captured after this point. Then, the image processing unit 11 repeatedly sends the image signal in the image memory 13 to the recording unit 12. As a result, the recording unit 12
The same image signal is repeatedly recorded on the magnetic tape, and as a result, the same image is repeatedly recorded.

Next, the shutter controller 14 controls the motor 1
6 is rotated to rotate the mirror 4 up to the stopper 6 (shown in FIG. 1), and the optical path from the lens 2 to the CCD sensor 3 is bent toward the still camera 7 in the middle thereof.
Subsequently, the shutter controller 14 controls the shutter mechanism 1
7 is operated to open and close the shutter 8 (shown in FIG. 1). As a result, a still image is recorded on the film 9 (shown in FIG. 1) in the still camera 7.

Thereafter, the shutter control section 14 rotates the motor 16 to return the mirror 4 to the original position, and the lens 2
The optical path from (as shown in FIG. 1) to the CCD sensor 3 is restored. Further, the shutter control unit 14 notifies the image processing unit 11 that the image pickup by the still camera 7 is completed. In response to this, the image processing unit 11 causes the image memory 1
Stop sending the image signal in 3 to the recording unit 12,
Instead, the formation of an image signal based on the signal from the CCD sensor 3 is restarted and this image signal is sent to the recording unit 12. Thereby, the capturing of the moving image is restarted.

Therefore, when the shutter button 15 is pressed, the video image pickup by the video camera 1 is interrupted, while the still image pickup by the still camera 7 is performed. Further, the video camera 1 repeatedly records the image immediately before being interrupted during the period in which the capturing of the moving image is suspended, and resumes capturing the moving image when the still image capturing by the still camera 7 is completed.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, as a lens, standard lens, telephoto lens, zoom lens, etc.
Any kind of thing may be applied. Further, a correction lens may be inserted in either one of the optical path from the lens to the CCD sensor and the optical path from the lens to the film.

The still camera 7 is replaced by the video camera 1
It may be detachably attached to.

[0023]

As described above, according to the present invention, the image to be recorded on the recording medium of the video camera does not drop even if the image is taken by the still camera during the image pickup by the video camera.
