Abstract

PURPOSE:To provide a camcorder provided with excellent convenience of use in which miss of shutter chance is eliminated and smooth panning is attained by visually confirming up to the surrounding of a recorded range on a screen of a view finder. CONSTITUTION:Zooming position information obtained by a zooming control circuit 6 is displayed on a screen obtained by a view finder lens 7 set to have an equal field angle to a maximum broad field angle of a lens section 1 while being synthesized on a screen of a view finder 4 as a zooming range by a zooming range display circuit 5, and then a photographer confirms it even when a scene desired to be picked up is produced at the outside of a range recorded at present to prevent miss of a shutter chance of the scene desired to be picked up.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated VTR having a viewfinder, and more particularly to a camera-integrated VTR having a zooming function.

[0002]

2. Description of the Related Art A camera-integrated VTR is equipped with a zooming function capable of continuously varying an image pickup range depending on a subject to be photographed, either telephoto or wide-angle. The camera-integrated VTR is equipped with a viewfinder that allows the photographer to visually recognize the screen imaged by the video camera unit.

FIG. 2 shows a block diagram of a conventional camera-integrated VTR, and its operation will be described.

The image picked up by the lens unit 1 is transmitted to the camera signal processing circuit 2 and converted into a video signal.
The video signal is transmitted to the VTR section 3 and recorded on the video tape. The viewfinder 4 receives the video signal output from the camera signal processing circuit 2 and displays it as an image.

However, the viewfinder of such a device outputs the screen imaged by the video camera unit and recorded by the VTR unit as it is as a monitor screen. The photographer is almost looking through the viewfinder during shooting, and it is difficult to check the surrounding conditions of the viewfinder. Even if the scene that the photographer wants to shoot occurs outside the viewable area of the viewfinder, the photographer cannot check the scene and may miss the scene that the photographer wants to shoot. In addition, when the device is panned and a picture is taken, the situation occurring in the panning direction is difficult to visually recognize in the viewfinder, and smooth panning cannot be performed.

[0006]

According to the above-mentioned conventional technique, the photographer almost looks into the viewfinder during photographing, and it is difficult to confirm the condition around the viewable area of the viewfinder. In this state, if the scene that the photographer wants to shoot occurs outside the visible range,
You may miss the scene you want to shoot.

The present invention has been devised to solve the above-mentioned problems, and its purpose is to take a picture by visually recognizing the periphery of the recording area on the viewfinder screen. It is to provide an easy-to-use VTR with a built-in camera that allows smooth panning without missing.

[0008]

[Means for Solving the Problems] The above-mentioned problem is to provide a viewfinder-specific lens, a viewfinder drive circuit, and a zooming range display circuit, and to provide a screen equivalent to the wide-angle maximum screen imaged by a video camera. This can be solved by setting the VTR section so that the angle of view obtained by the zooming function is displayed on the viewfinder as a zooming range and the zooming range is recorded by the VTR section.

[0009]

[Operation] The zooming range display circuit displays the zooming position information obtained from the zooming control circuit on the screen obtained from the lens part for the viewfinder set to the same angle of view as the wide angle maximum angle of view of the lens part. By combining and displaying the zooming range on the screen of, the photographer can check the scene that the photographer wants to shoot even if it occurs outside the currently recorded range, and prevent missing of the scene that the photographer wants to shoot. You can

A method for displaying the range on the screen of the viewfinder is disclosed in JP-A-58-40982.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a camera-integrated VTR showing an embodiment of the present invention. 1 is a lens unit, 2 is a camera signal processing circuit, 3 is a VTR unit, 4 is a viewfinder, and 5 is zooming. A range display circuit, 6 is a zooming control circuit, 7 is a viewfinder lens, and 8 is a signal combining unit.

The video signal picked up by the lens unit 1 is
The video signal is converted by the camera signal processing circuit 2 and output to the VTR unit 3. The VTR section 3 inputs the video signal and records it on a video tape. The zooming control circuit 6
The zoom lens of the lens unit 1 is controlled to continuously change the video signal input to the camera signal processing circuit 2 from wide angle to telephoto or from telephoto to wide angle. Viewfinder lens 7
Is set to a magnification equivalent to the wide-angle maximum of the lens unit 1 and outputs an image to the viewfinder 4. The zooming range display circuit 5 takes in the position information of the zoom lens from the zooming control circuit 6 and synthesizes it with the image of the viewfinder lens 7 by the synthesizing section 8 to form a viewfinder 4
Output to.

FIG. 3 shows a viewfinder screen of a camera-integrated VTR using one embodiment of the present invention.
Is a viewfinder angle of view, and 12A to 12C are zooming ranges.

During operation of the zooming function, the zooming range (12A to 12C, etc.) depending on the position of the zoom lens of the lens unit 1 is maintained without changing the angle of view of the viewfinder screen 11.
Is displayed. As a result, for example, when the zoom lens is located at the telephoto position, the zooming range is displayed at the position of 12A, and the surrounding condition is also the view angle of the viewfinder.
By displaying it in the inside, the photographer can confirm the situation around the currently recorded screen, and can easily confirm the scene to be photographed next.

FIG. 4 is a block diagram of a camera-integrated VTR using an electronic zoom function according to an embodiment of the present invention.
The electronic zoom is a zooming method in which a part of the angle of view picked up by a CCD sensor is cut out and enlarged for output. Information on the zooming range cut out by the camera signal processing circuit 2 is taken into the zooming range display circuit 5, and the lens unit 1
The signal output from the zooming range display circuit 5 is combined with the video signal output from the signal combiner 8 to obtain the viewfinder 4
By displaying in, the photographer can confirm the periphery of the angle of view recorded on the tape as described in FIG.

FIG. 5 shows an embodiment of the present invention, in which the screen switching circuit 9 and the switching switch 10 are provided in the zooming range display function explained in FIG. 1, and the angle of view recorded in the VTR section 3 is also unchanged. It can be displayed on the viewfinder 4. Depending on the use of the photographer, it is possible to switch between the case where it is desired to confirm the periphery of the zooming range and the case where it is desired to confirm the angle of view to be recorded by the switch 10.

By configuring the apparatus in this way, the photographer can grasp the scene that the user wants to photograph around the angle of view currently recorded on the video tape. This allows the photographer to match the angle of view to the subject,
Never miss a scene you want to shoot.
Further, when the device is panned and the image is taken, the situation occurring in the panning direction can be visually confirmed by the viewfinder, so that smooth panning can be performed.

[0019]

According to the present invention, even when the scene desired to be photographed by the photographer occurs outside the visible range on the viewfinder screen, the periphery of the recorded range on the viewfinder screen can be visually recognized. It is possible to provide an easy-to-use VTR with a built-in camera that allows smooth panning without missing a shot.
