Abstract

PROBLEM TO BE SOLVED: To attain simultaneous monitor of a moving image and a reproduced image by displaying a video image of a camera on one monitor and displaying the video image of the camera or a special video image such as a reproduced image and a still image on another monitor. SOLUTION: A signal from a camera section 1, a signal from a memory 15 storing the signal from the camera section 1, and a reproduction signal from a video head 2 amplified by an amplifier 3 are inputted to a luminance color signal processing circuit 4. The camera signal and the signal through the memory 15 are subjected to prescribed processing and inputted to a recording signal processing circuit 7. A switch 17 selects the camera signal 5, a memory signal 16 and the reproduction signal 6 and provides an output of the selected signal to a liquid crystal monitor 12 and a switch 18 selects the camera signal 5, the memory signal 16 and the reproduction signal 6 and provides an output of the selected signal to an EVF 13. Simultaneous monitor of a moving image and a reproduced image is attained by displaying the camera image a special video image such as the reproduced image and the still image on a plurality of the monitors.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated VTR.
About.

[0002]

2. Description of the Related Art In a conventional camera-integrated VTR having a liquid crystal monitor and an EVF, the power of the EVF is turned off when the power of the liquid crystal monitor is turned on, and the power of the liquid crystal monitor is turned off when the power of the EVF is turned on. Or a system in which the same image is projected on the liquid crystal monitor and the EVF. An example of this is VIDEOC published by Gakken
APA, April 1995, pages 20, 21.

[0003]

In the conventional system, in a camera recording standby mode, a reproduction start point is searched for by looking at a reproduced image of a recorded section, or a reproduction is performed in a camera recording standby mode to determine whether or not recording has been performed as desired. In such a case, the camera image cannot be seen. Also,
Even when a special image such as a still image is recorded using a digital function, the moving image of the camera cannot be seen while the special image is displayed on the monitor. In this system,
While special images such as playback images and still images are displayed on the monitor, the camera images cannot be viewed, and during that time, the camera cannot be adjusted, such as adjusting the zoom position or focusing, and the playback images and still images cannot be viewed. In some cases, the photographer missed the chance to take a picture without quickly entering the camera after the picture was taken.

[0004]

Means for Solving the Problems As means for solving the above problems, in a camera photographing mode, an image of a camera is always displayed on any one of a plurality of monitor devices mounted on a camera-integrated VTR. Projection, another monitor usually shows the image of the camera, or if the power is off and it is necessary to monitor a special image such as a playback image or a still image, make it possible to project the image Thereby, the moving image of the camera and the reproduced image or the special image can be simultaneously monitored.

According to the present invention, it is possible to view a moving image of a camera even when a special image such as a reproduced image or a still image is projected, and to adjust a zoom position and a focus while watching the reproduced image or the special image. Camera can be adjusted. In addition, when it is not necessary to view a reproduced image or a special image except for a monitor that constantly displays the image of the camera, power can be saved by turning off the power.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments.

FIG. 1 shows a camera-integrated V according to an embodiment of the present invention.
FIG. 3 is a block diagram illustrating a configuration of a TR.

In FIG. 1, 1 is a camera unit, 2 is a video head, 3 is a reproduction amplifier, 4 is a luminance / color signal processing circuit,
5 is a camera signal, 6 is a reproduction signal, 7 is a recording signal processing circuit, 8 is a switch, 9 is a switch, 10 is a microcomputer, 11 is a switch, 12 is a liquid crystal monitor, 13 is an electric view finder (EVF), 14
Are operation keys.

Next, the operation of this embodiment will be described.

A signal from the camera unit 1 and a video head 2
The reproduction signal obtained by amplifying the signal from the reproduction amplifier 3 is input to the luminance / color signal processing circuit 4, and the camera signal is subjected to predetermined processing here and sent to the recording signal processing circuit 7. The switch 8 switches between the camera signal 5 and the reproduction signal 6 and outputs the signal to the liquid crystal monitor 12. The switch 9 switches between the camera signal 5 and the reproduction signal 6 and outputs the signal to the EVF 13. The switch 11 switches which of the liquid crystal monitor 12 and the EVF 13 is fixed to the camera signal 5. Switching between the switches 8 and 9 is performed by the microcomputer 10, and the camera signal 5 is selected unless the reproduction signal 6 is selected by the operation keys 14.

According to this method, the zoom position and the like of the camera can be adjusted while monitoring the reproduction signal for searching the recording start position of the tape.

FIG. 2 shows a configuration in the case where there is a function of recording a still image and an embodiment of power saving.

In FIG. 2, 15 is a memory, 16 is a memory signal, 17 is a switch, 18 is a switch, 19 is an operation key, and 20 is a power supply circuit.

In the configuration shown in FIG. 2, a signal from the camera unit 1, a signal stored in the memory 15, and a reproduced signal obtained by amplifying the signal from the video head 2 by the amplifier 3 are converted into a luminance / color signal processing circuit 4. Input to the camera signal and memory 15
The signal passed there is subjected to predetermined processing here, and is sent to the recording signal processing circuit 7. The switch 17 switches between the camera signal 5, the memory signal 16, and the reproduction signal 6, and
Output to 2. The switch 18 switches between the camera signal 5, the memory signal 16, and the reproduction signal 6, and outputs the signal to the EVF 13. The switch 11 switches which of the liquid crystal monitor 12 and the EVF 13 is fixed to the camera signal. Switch 1
7 and the switch 18 are switched by the microcomputer 1
0, and the camera signal 5 is selected except when the memory signal 16 or the reproduction signal 6 is selected by the operation key 19.
When a monitor that is not fixed to the camera signal 5 does not need to view a reproduced image or a special image, power can be saved by turning off the power supply circuit 20.

According to this method, it is possible to adjust the camera such as the zoom position while checking the reproduction signal 6 and the memory signal 16.

[0016]

According to the present invention, it is possible to check a recorded portion in a reproduced signal, search for a recording start portion, or the like, or
It is possible to adjust the zoom position and the like of the camera while checking a special image such as a still image. In addition, when it is not necessary to view the reproduced image and the special video, the monitor that displays the reproduced image and the special video can automatically save power to save power.
