In addition, the connection is set to the input state within a predetermined time, the connection status is judged by the presence or absence of the vertical or horizontal synchronizing signal in the input video signal, and if the connection is not properly made, the viewfinder 7 or the main body displays a warning, and the system Does not work.

Description

Detailed Description of the Invention

[0001]

[Industrial application] With the trend toward miniaturization of video cameras, input / output terminals are commonly used, and this changeover has conventionally been performed using a changeover switch for human judgment. According to the present invention, it is possible to switch automatically, and it is possible to avoid a human error.

[0002]

2. Description of the Related Art A conventional apparatus is, for example, "Television Technology" published by Electronic Technology Publishing Co., Ltd., January 1990, P87, 90, 91.
As shown in, the miniaturized VTR and camera integrated VT
The R has a mechanical input / output changeover switch and the like, and when the input / output is changed over, the connection cord is made an intended connection, and the state of the camera-integrated VTR side is changed over by this changeover switch.

[0003]

In a camera-integrated VTR that shares an input / output terminal, it is necessary to switch the state setting of the camera-integrated VTR, that is, the input / output state setting, in addition to the wiring connection. Because I went personally,
There was incorrect connection or incorrect switching.

[0004]

As a means for solving the conventional problems, input / output switching is automatically performed, and regarding the connection error, the error is shown to the user and the operation does not change.

[0005]

In a camera-integrated VTR having an input / output switching device and an input / output control device for automatically determining input / output switching by operating buttons, a state determination switch, etc., the video signal to be connected is temporarily input. It is possible to avoid human error by judging whether there is a vertical or horizontal sync signal, showing the connection error information to the user when the connection is incorrect, and preventing the transition to the operation intended by the user. I can.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows a conventional compact video and camera integrated type V.
The dual input / output terminal system used in TR is shown below. I / O is left to the user, so that if it is input, the main body is input,
If it is an output, a mechanical input / output switching device 1 which connects video and audio signal codes to the input / output terminal 10 so that the main body outputs and does not control the input / output state on the video camera side.
Input / output switching was performed according to 1. However, recording / reproduction cannot be performed due to an error in connection between the video and audio signal codes and an error in switching the mechanical input / output switching device due to an error in human judgment.

FIG. 1 shows a configuration of the present invention, and FIG. 2 shows a flow chart for automatic input / output discrimination and erroneous connection avoidance. The system control device 5 includes a video signal input / output switching device 8 controlled by the system control device 5 provided between the video signal processing device 3 and the input / output terminal 10, and an audio signal processing device 4 and the input / output terminal 10. For the audio signal left input / output switching device 9a and the audio signal right input / output switching device 9b provided between
Send a control signal so that the main body of the set is in the input state.
The presence / absence of a vertical synchronizing signal or a horizontal synchronizing signal in the signal input by the video signal processing device 3 is determined, and the information is transmitted to the system control device 5. Next, operation keys, status switch 6
Then, information such as recording is transmitted to the system controller 5. When there is a vertical or horizontal synchronizing signal, the video signal input / output switching device 8 and the audio signal left input / output switching device 9
a, The audio signal right input / output switching device 9b is instructed to input, and the system operation is brought into a recording state. If there is no vertical or horizontal synchronizing signal, or if a reproduction instruction is transmitted from the operation keys or the state switch 6 to the system control device 5, the connection abnormality information is transmitted to the viewfinder 7.
Don't let the system enter the recording state either. Also, there is no vertical or horizontal sync signal, so operation keys and status switch 6
When a reproduction command is transmitted to the system control device 5 by the command, the video input / output switching device 8, the audio signal left input / output switching device 9a, and the audio signal right input / output switching device 9b are instructed to output, and the system is also in a reproducing state. And If a recording instruction is sent from the operation keys and the status switch 6 to the system control device 5, the abnormal condition is transmitted to the viewfinder and the system is prevented from entering the reproducing state as described above.

[0008]

According to the present invention, input / output can be automatically performed, the input / output changeover switch can be deleted, a warning is displayed for incorrect connection, the system is not operated, and human error is promptly notified. You can avoid it.
