Abstract

PROBLEM TO BE SOLVED: To improve handleability by mixing signals from a camera part and the signals of a small screen obtained by compressing the signals from a reproducing circuit and displaying them on an electronic view finder. SOLUTION: When the changeover switch of a camera is on a video side, video signals from the reproducing circuit 7 are reproduced and displayed at the finder 10 through a video signal circuit 8 and a mixing circuit 9. Also, when it is on a camera side, the video signals from the camera part 1 are outputted, the image pickup output of the camera part 1 is outputted to the view finder 10 as it is when a recording/recording standby switch is set to a recording side and the ON/OFF of a scene searching button 3 are judged when it is set to a recording standby side. Then, when the button 3 is set to a positive or reverse direction, recording signals are reproduced in a prescribed mode and compressed in the video signal circuit 8 and the compressed signals and the signals from the camera part 1 are mixed in the mixing circuit 9 and outputted to the electronic view finder 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video tape recorder integrated with a camera (hereinafter referred to as "camcorder").

[0002]

2. Description of the Related Art There is a so-called scene search function which allows a tape to be reproduced in a camera standby state in order to confirm a recording position of a tape when an image is picked up by a camcorder.

[0003]

In the conventional scene search function of the camcorder, only the tape reproduction output is displayed on the viewfinder, and the output video signal from the camera section is not displayed.

Therefore, the present invention seeks to overcome such drawbacks.

[0005]

SUMMARY OF THE INVENTION The present invention comprises a camera section,
A recording circuit for recording a video signal picked up by the camera unit, a reproduction circuit for reproducing the video signal recorded by the recording circuit, and a video for compressing the reproduction video signal obtained from the reproduction circuit to create a small screen. The reproduction includes a signal processing circuit, a mixing circuit that mixes a video signal obtained by the camera unit and a sub-screen signal obtained by the video signal processing circuit, and a display unit that displays the signal obtained by the mixing circuit. This is a camera-integrated VTR in which a video signal obtained from a camera unit when a recorded video signal is reproduced by a circuit is displayed on the display means as a small screen.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a camera-integrated VT embodying the present invention.
1 is a block diagram of a main part of R, in which 1 is a camera unit having a CCD as an image pickup element, 2 is a recording circuit for recording a video signal picked up by the camera unit, 3 is a forward direction reproduction (+) button and a reverse direction button. A scene search button having a direction (-) button, 4 is a time detection circuit for measuring the pressing time of the button 3, 5 is a mode switching circuit for switching the reproduction mode by receiving the output of the time detection circuit, and 6 is A reproduction signal detection circuit, a reproduction circuit 7 for reproducing the recorded signal, and a reference numeral 8 for receiving the video signal (a) from the camera section and the reproduction video signal (b) from the reproduction circuit 7 and A video signal processing circuit for thinning out and compressing n, 9 is a video signal mixing circuit capable of mixing output signals (a) and (b) from the video signal circuit 8 and outputting a mixed video signal (d), 10 is Video signal (10 It is an electronic view finder to display in.

Next, the operation of FIG. 1 will be described with reference to the operation flowchart of FIG. 2. First, in step 1, it is judged whether the changeover switch of the camera is the camera side or the video side. The video signal from 7 is reproduced (S12), and only the video signal is displayed on the finder 10 through the video signal circuit 8 and the mixing circuit 9 (S13).

Further, in step 1, it is judged whether the changeover switch of the camera is the camera side or the video side, and if it is the camera side, the video signal from the camera section 1 is output (S2), and then the recording / recording standby switch. If is set to the recording (REC) side (S3), the image pickup output of the camera unit 1 is output to the viewer 10 as it is (S14).

Next, if the recording / camera standby switch is set to the recording standby (STNBY) side (S
3) Next, it is judged what the scene search button 3 is, and if the button 3 is off, the viewer output is performed (S14). Further, if the button 3 is set to the forward direction, the normal reproduction of 1 time is performed, but the time during which the button is pressed is measured by the time detection circuit 4 (S6). If this pressing time is a predetermined time or more,
The mode switching circuit 5 switches the reproduction mode so as to perform high speed reproduction of 1 time or more, for example, 7 times.

On the other hand, when the button 3 is set in the reverse direction (-), the reproduction signal from the reproduction circuit 7 is detected (S
5) If detected, the operations in steps 6 to 11 are performed in the same manner as in the forward direction, that is, reverse 1 × speed reproduction and reverse 7 × speed reproduction if pressed for a predetermined time or longer. When the button 3 is set in the reverse direction (-) and the reproduction signal from the reproduction circuit 7 is not detected, the mode switching step (S7) shifts to the rewind mode.

This is because the mode for shifting to the high-speed reproduction depending on the pressing time of the button enables the smoothing operation for connection.

As described above, the scene search button 3
Is set to normal or reverse, the recording signal is reproduced in a predetermined mode (S8) (reproduced video signal b), and the video signal circuit 8
(S9), and the mixed signal (c) and the signal (a) from the camera section 1 are mixed by the mixing circuit 9 (S10) and output to the electronic viewfinder (S10).

[0014]

As described above, according to the present invention, there is an advantage that the reproduced image can be confirmed while always confirming the subject with the viewfinder, and the usability can be improved.

When the button 3 is set in the reverse direction (-) and the reproduction signal from the reproduction circuit 7 is not detected, the mode switching step (S7) is performed so as to shift to the rewind mode. Furthermore, by switching the mode to high-speed playback depending on the button pressing time,
The operation for connecting can be smooth.
