Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention can be used as an ultra-compact camera by separating the imaging section from the signal processing section. [Summary of the Invention] The present invention has an optical lens and By separably connecting an imaging section equipped with an imaging device and a switch to a signal processing section that processes the output signal of the imaging device, the imaging section can be separated from the signal processing section and used as an ultra-compact camera. It was made so that it could be done.

[Conventional technology]

For example, as seen in Japanese Utility Model Application Publication No. 62-203570, video cameras have traditionally had a camera body with a shoulder strap attached to the bottom surface, and an optical lens, a viewfinder, a handle, etc. Various adjustment switches and the like are attached, and an image sensor, a signal processing circuit for processing output signals of the image sensor, and the like are housed inside the camera body.

[Problem to be Solved by the Invention] Therefore, in a conventional video camera, an imaging unit including an optical lens, an image sensor, and an adjustment switch is separated from a signal processing unit including a signal processing circuit, and the imaging unit is separated from a signal processing unit including a signal processing circuit. Its structure made it completely impossible to use it as an ultra-compact camera.

An object of the present invention is to provide a video camera system in which an imaging section is separated from a signal processing section and can be used as an ultra-compact camera.

[Means for Solving the Problems] In order to achieve the above object, the video camera system of the present invention includes an imaging section including an optical lens, an imaging device, a switch, and an output of the imaging device. A signal processing section that processes a signal, a connection means that connects the imaging section and the signal processing section in a separable manner, and a cable that electrically connects the imaging section and the signal processing section in a separated state. It is equipped with the following.

[Function] In the video camera system configured as described above, the imaging section and the signal processing section can be connected and separated by the connecting means, and the imaging section can be separated from the signal processing section.
By connecting these with a cable, the imaging unit including an optical lens, an image sensor, and a switch can be used as an ultra-compact camera.

(Embodiment) Hereinafter, an embodiment of a video camera system to which the present invention is applied will be described with reference to the drawings.

First, the camera body 1 includes an imaging section 2 and a signal processing section 3 that are separable.

Externally, the imaging unit 2 includes an optical lens 20, a viewfinder 21, adjustment switches (power switch, white balance switch, black balance switch, gain adjustment switch, etc.) 22, and operation switches (VTR start,
A stop switch, a zoom switch, etc.) 23, a foldable or removable chest pad 24, etc. are attached. Also, inside the imaging unit 2, an imaging device 2 such as a CCD is provided.
5. An image sensor drive board 26 and the like are attached.

A shoulder pad, a pad 30, etc. are attached to the outside of the signal processing section 3, and a signal processing board 31 constituting a signal processing circuit for processing the output signal of the image sensor 25 is attached to the inside.

The connection means 4 for separably connecting the imaging section 2 and the signal processing section 3 includes a plurality of connection protrusions 41 having screw holes 40;
The imaging unit 2 is removably screwed into these screw holes 40.
and a plurality of connection screws 42 that connect the signal processing section 3 and the signal processing section 3.

At both ends of the cable 5 that electrically connects the imaging section 2 and the signal processing section 3 in a separated state, a pair of cable sides are connected to an imaging section side connector 50 and a signal processing section side connector 51, respectively. These cable side connectors 51 and 52 are connected to the imaging section side connector 5.
0 and the signal processing section side connector 51 by a pair of tightening rings 54 and 55 screwed onto the outer periphery of the signal processing unit side connector 51.

Note that a handle 6 is attached to the top of the imaging section 2 and the top of the signal processing section 3 so as to be replaceable. Further, at the rear of the signal processing section 3, as in the conventional case, a VTR 7 and an AC adapter (not shown) are configured to be replaceably attached.

According to the video camera system configured as above, first, as shown in FIG. 2, when used as a VTR-type camera, the imaging section 2 and the signal processing section 3 are fitted from the front and back, By screwing and tightening the plurality of screws 42 of the connecting means 4 into the screw holes 40 of the plurality of protrusions 41,
The imaging section 2 and the signal processing section 3 are combined together to form an integrated camera body 1. In addition, at this time, the signal processing section side input terminal 51 is directly connected to the imaging section side input terminal 50,
The imaging section 2 and the signal processing section 3 are electrically connected. A VTR 7 is attached to the rear of the signal processing section 3, and a handle 6 is attached to the upper part of the signal processing section 3 so that the entire camera can be handled in a well-balanced manner.

When used as a system camera, an AC adapter (not shown) is attached to the rear of the signal processing section 3, and a handle 6 is attached to the top of the imaging section 2 so that the entire camera can be handled in a well-balanced manner.

When shooting video as a VTR-integrated camera or system camera, use the shoulder rest pad 30 to hold the entire camera.
The camera is placed on the cameraman's shoulder, and the whole camera is stabilized by the chest pad 24. Then, operate the switches 22 and 23 of the most image section 2 to capture the desired video.

Next, as shown in FIG.
Remove the screw 40 from No. 1 to separate the imaging section 2 and the signal processing section 3. Then, the cable-side connectors 52 and 53 at both ends of the cable 5 are connected to the imaging unit side connector 50 and the signal processing unit side connector 51, respectively, and the pair of tightening rings 5
The imaging section 2 and the signal processing section 3 are electrically connected by the cable 5 by screwing the connectors 4.55 onto the outer peripheries of both the connectors 50 and 51 and tightening them. As a result, the imaging unit 2 including the optical lens 20, viewfinder 21, switches 22, 23, image sensor 25, etc. can be used as an ultra-compact camera separated from the signal processing unit 3. Note that the handle 6 is attached to the upper part of the imaging section 2 in consideration of handling.

When taking a video with the ultra-compact camera, the cameraman stabilizes the entire imaging unit 2 by supporting it with both hands, and then operates the switches 22 and 23 to take a desired stereoscopic image. At this time, if the shoulder rest pad 30 is attached to the imaging unit 2 side via a mounting bar etc. from the beginning, the imaging unit 2
can be placed on the cameraman's shoulder using the shoulder pad 30 to take a video. Furthermore, if the chest band 24 becomes an obstacle during video shooting, it may be folded or removed.

When the imaging unit 2 is used as a micro-compact camera, it is very convenient for taking video in a very narrow place, such as inside a car or a helicopter.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various effective changes can be made based on the technical idea of the present invention.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the following effects.

By separating the imaging section from the signal processing section using a connecting means and connecting them with a cable, the imaging section equipped with an optical lens, an image sensor, and a switch can be used as an ultra-compact camera. Since this is a separable video camera system, it is very convenient when viewing video images in very narrow spaces, such as inside a car or helicopter.
