Abstract

PURPOSE:To provide the video camera recorder which can record a main object as well as a sub-object such as a photographer itself. CONSTITUTION:A first image pickup means 201 picks up the image of an object. A second image pickup means 202 picks up the image of the photographer operating the first image pickup means 201 as an object. A video synthesizing means 203 prepares a third video signal by synthesizing first and second video signals outputted from the first and second image pickup means 201 and 202. A recording means 204 records the third video signal in tape 205 being a recording medium. Thus, the photographer to photograph the object can be recorded in the recording medium and kept in the record as well.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera recorder for shooting and recording images.

[0002]

2. Description of the Related Art With the widespread use of video camera recorders in recent years, various events have been taken with video camera recorders.
Recording is becoming more common.

FIG. 6 shows a block diagram of a conventional video camera recorder. 601 is an image pickup means for converting an external image into a video signal, 602 is a recording means for recording the video signal on a tape, and 603 is a tape. The user turns the image pickup means 601 toward the subject and starts photographing. The image pickup means 601 converts the image of the subject into a video signal. A composite video signal (usually called a composite video) is generally used as a video signal, and the NTSC system among them is adopted in Japan and the United States. The recording unit 602 converts the video signal into a format for recording on a tape, and then records it on the tape 603 with a magnetic head or the like. As a conversion method for home-use video camera recorders, a composite video signal is separated into a luminance signal and a chrominance signal with a low-pass filter, etc., then low-pass conversion is performed on the chrominance signal, and the low-pass cut luminance signal is superimposed with a high-pass filter The VHS method and the beta method are typical ones. Regarding signal processing and tape recording, for example,
P73-P of "Video Technology Handbook" published by Denpa Shimbun
88 etc. have detailed explanations, so further explanation is omitted.

[0004]

However, in the above video camera recorder, since the image pickup means is one system, when the main subject is photographed, the sub subject, for example, the photographer operating the video camera recorder is photographed. I can't do it. There was a problem that it could not be recorded.

The present invention solves the above-mentioned conventional problems, and provides a video camera recorder having two systems of image pickup means and capable of recording a sub-subject such as a photographer.

[0006]

To achieve this object, a video camera recorder according to the present invention comprises a first image pickup means, a second image pickup means, and a first image pickup means which is an output of the first image pickup means. Synthesizing means for synthesizing the video signal and the second video signal output from the second imaging means into a third video signal,
And a recording means for recording the third video signal.

Further, the video camera recorder of the present invention is
A first image pickup means, a second image pickup means that can be separated from the first image pickup means, a transmission means that transmits a second video signal output from the second image pickup means as a transmission signal, and a transmission signal is received. Receiving means for outputting as a third video signal, and a video synthesizing means for synthesizing the first video signal output from the first imaging means and the third video signal into a fourth video signal. ,
And a recording means for recording the fourth video signal.

Further, the video camera recorder of the present invention is
The image synthesizing unit has a configuration including a synthesizing position control unit that controls the synthesizing position of the second image signal with respect to the first image signal.

[0009]

With the above-described structure, the video camera recorder of the present invention shoots a subject, which is the main purpose of shooting, with the first image pickup means, and shoots a sub-subject such as a photographer with the second image pickup means. The two images will be combined and recorded on the tape.

Further, the video camera recorder of the present invention is
The image captured by the second image capturing unit that can be separated from the first image capturing unit is wirelessly transmitted to the main body side including the first image capturing unit.

The video camera recorder of the present invention is
The position of the image of the sub-subject to be combined with the image of the main subject is controlled by the combining position control means.
