Abstract

PURPOSE:To provide a video camera which can execute video recording from the moment a video recording SW is depressed. CONSTITUTION:This camera 1 outputs a picked up video signal, and the outputted video signal is outputted to a VTR 2. In a contact state detecting part 3, whether a photographer's hand comes into contact with a video recording SW or not, and a contact detecting signal is outputted. In a video recording SW state detecting part 4, whether the photographer depresses the video recording SW or not is detected, and a start/stop signal is outputted. In a VTR control part 5, from the contact detecting signal and the start/stop signal, video recording start preparations are executed, in the case the photographer's hand comes into contact with the video recording SW, and the VTR 2 is controlled so that video recording is started from the moment the video recording SW is depressed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera.

[0002]

2. Description of the Related Art In a conventional video camera, a method of starting recording after pressing a recording start / stop button is often used.

This method will be described in detail with reference to FIG.
The camera 1 outputs the captured video signal. The video signal is output to VTR2. In addition, the recording SW state detection unit 4
Then, it is detected whether the recording start / stop switch is pressed,
Detects start / stop signals. The VTR control unit 3 controls, based on the start / stop signal, to start recording in the recording stopped state and stop recording in the recording state.

[0004]

However, in the above method, the video camera usually needs a preparation period from the recording stop state to the recording start. Therefore, when the photographer presses the recording SW at the moment when he / she wants to take a picture. However, there was a slight time lag, so there was a problem that I could not shoot the scene at the moment I wanted to shoot.

In view of the above point, the present invention detects that the photographer is touching the recording SW of the video camera, and at that time, the photographer completes the preparations for starting the recording, and the photographer performs the recording S.
An object of the present invention is to provide a video camera capable of recording from the moment when W is pressed.

[0006]

In order to solve the above problems, the automatic exposure control apparatus according to the present invention converts the result of detecting whether or not the photographer's hand is touching the recording SW into a contact detection signal. A contact state detection unit, a recording SW state detection unit that converts the result of detection whether the recording SW is pressed or not into a start / stop signal, and a VTR that controls the VTR based on the contact detection signal and the start / stop signal. It is provided with a control unit.

[0007]

According to the present invention, by providing the above means, it is possible to detect that the photographer's hand is touching the recording SW, and at that point, the preparation for the start of recording is completed, after which the photographer presses the recording SW. Enable recording from the moment you start.

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

FIG. 1 is a block diagram of a video camera of this embodiment. In FIG. 1, 1 is a camera unit that outputs a captured video signal, 2 is a VTR that records the video signal output from the camera unit 1, and 3 is whether or not the photographer's hand is touching the recording SW. Contact state detection unit, 4 is a recording SW
The recording SW state detection unit 5 for detecting whether or not is pressed, and the recording S state detection unit 5 and the recording S
VTR2 by the start / stop signal from the W state detector 4
Is a VTR control unit for controlling the.

Hereinafter, the detection method performed by the contact state detection unit 3 will be described in detail with reference to FIG.

FIG. 2 shows a recording S for detecting the contact of the photographer's hand.
The structure of W is shown. As shown in FIG. 2, the recording SW is 2
It is composed of electrodes 21 and 22 made of one metal piece. When the photographer's hand touches the electrodes 21 and 22, the electrodes are short-circuited, a current flows between the electrodes, and the potential 23 rises.
From the potential 23, it is possible to detect whether or not the photographer is touching the recording SW.

Further, the recording SW state detecting section 4 detects whether or not the photographer has pressed the recording SW, and outputs a start / stop signal.

The VTR control section 5 prepares to start recording when the photographer's hand is touching the recording SW from the contact detection signal and the start / stop signal, and starts recording when the recording SW is pressed. Control the VTR so that

By taking the above steps, the photographer can record S
You can shoot from the moment you press W.

[0015]

As described above, according to the present invention, by providing the contact state detecting unit for detecting whether or not the hand of the photographer is touching the recording SW, before the photographer presses the recording SW. Since you can prepare to start recording, you can provide a video camera that allows you to record from the moment you press the recording SW, and the normal photographer sets the angle of view while touching the recording SW before recording and the moment you want to shoot. Since you can record the video from
Its practical effect is great.
