Abstract

PURPOSE:To constitute a video camera so that a person being an object can recognize easily various operating states of the video camera by displaying various operating states of the video camera by plural pieces of display lamps provided in front of the video camera, and also, along a peripheral edge of a camera lens. CONSTITUTION:A detecting circuit 2 detects various operating states of a video camera 1, and outputs its check signal to a system controller 3. The controller 3 outputs a state of each check signal to a control circuit 4, and also, controls an electric system circuit 6 and a camera system 7, based on a command signal of a key input part 5. The circuit 6 executes a recording/reproducing signal processing, etc., and the mechanism system circuit 7 drives the mechanism part. The circuit 4 controls a display state of plural display lamps 8 in accordance with the state of the check signal. Accordingly, a person being an object knows various operating states of the video camera 1 by looking at the display state of the lamp 8, therefore, in the case a failure of photographing, etc., are generated, it can be pointed out to a photographer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera, and more particularly to a technique for displaying its operating status.

[0002]

2. Description of the Related Art A conventional video camera viewfinder is provided with a display section for indicating various operating states, so that only a photographer can recognize the operating state of the video camera. For the person who is the subject, there is only one that can be provided with one tally lamp outside the viewfinder so that the person slightly knows whether or not shooting is in progress.

[0003]

However, informing the person who is the subject of the various operating states of the video camera is useful for preventing the failure of photographing.
Further, since the position of the conventional tally lamp is in the viewfinder portion, it is difficult for a person as an object to recognize it.

Therefore, it is an object of the present invention to provide a video camera in which a person as a subject can easily recognize various operating states.

[0005]

A video camera according to the present invention for achieving the above object comprises a detection circuit for detecting an operating state of the video camera, and a front surface of the video camera,
In addition, it comprises a plurality of display lamps provided along the peripheral edge of the camera lens, and a control circuit for controlling the display state of the plurality of display lamps according to the output of the detection circuit.

[0006]

According to various operating states of the video camera, a plurality of display lamps are turned on, turned off, blinking, etc., and these display lamps are most likely to be watched by a person who is a subject, and are easy to see. It is provided on the periphery of the camera lens.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show one embodiment of the present invention.

FIG. 1 is a circuit block diagram of the video camera 1. In FIG. 1, a detection circuit 2 indicates whether the video camera 1 is in an autofocus state, a wind noise state, a white balance state, a fader on / off state, a hiight mode presence / absence, a standby state, a battery capacity state, a tape running state, or a recording state. It also detects whether or not it is close to the tape end, whether or not there is backlight compensation, and outputs these check signals to the system controller 3.

The system controller 3 outputs the state of each check signal to the control circuit 4 and controls the electric system circuit 6 and the mechanical system circuit 7 based on the command signal from the key input section 5. The electric system circuit 6 performs signal processing such as recording and reproduction, and the mechanical system circuit 7 drives a mechanical portion.

The control circuit 4 controls the display state of the plurality of display lamps 8 according to the state of each check signal. As shown in detail in FIG. 2, the plurality of display lamps 8 are provided on the front surface of the video camera 1 and at regular intervals along the peripheral edge of the camera lens 9. A display target is shown in the vicinity of each display lamp 8, and the state of this display target is indicated by a lighting, extinguishing, or blinking state.

A tape end whose display target is not shown,
The battery status and the tape running status are displayed as shown in FIGS. That is, when it is detected that it is near the tape end, all the display lamps 8 blink as shown in FIG. When it is detected that the remaining battery level is low, as shown in FIG.
The indicator lamp 8 for every other piece flashes. The tape running state is displayed by changing the lighting position according to the running speed and running direction.

In the above structure, the detection circuit 2 detects various operating states of the video camera 1, and the control circuit 4 controls the display state of the display lamp 8 based on the detection result. Therefore, the person who is the subject can see various operating states of the video camera 1 by looking at the display state of the display lamp 8.
If there is a defect in photographing, it can be pointed out to the photographer.

The display lamps 8 are most likely to be watched by the person who is the subject, and can be easily recognized because they are provided on the periphery of the camera lens 9 which is easy to see.

[0014]

As described above, according to the present invention, various operating states of the video camera can be displayed on the front surface of the video camera.
In addition, since the display is performed by a plurality of display lamps provided along the periphery of the camera lens, the person who is the subject can easily recognize the operation state of the video camera.
