Abstract

PURPOSE:To suppress the consumption of a battery to realize immediate recording by always storing the video input signal of plural pictures in a memory and controlling a rotary head and tape running to record the signal read out from the memory by standby on. CONSTITUTION:Light enters from a lens 11 to a CCD 12, and the output signal is inputted to a switch 14 through a process circuit 13. When switches 14 and 18 are switched to the side (a) while interlocking with each other, the video signal is stored in a memory 16 through an A/D converter 15. A control circuit 23 reads out the signal from the memory 16 by standby on and converts it into a video signal through a D/A converter 17 and the switch 18 by an encoder 19 and records it on a cassette tape 22 by a recording circuit 20. The control circuit 23 controls the timing of recording.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated video device for recording video signals or audio signals.

[0002]

2. Description of the Related Art Recently, integrated video devices have been widely used especially for business use and home use, and the purpose of use has been diversified.

The structure of the integrated video apparatus will be described below with reference to the drawings. FIG. 3 is a circuit diagram showing the configuration of a conventional integrated video device. In FIG. 3, the light input from the lens 11 is converted into an electric signal by the CCD 12, and this signal is converted into an input signal by the process circuit 13. It is set to a constant level and then converted into a video signal by the encoder 19. This signal is amplified by the recording circuit 20, sent to the video head 21, and recorded on the cassette tape 22.

The control circuit 23 is a circuit for controlling the recording timing. For recording, the cassette tape 22 is stably run and recording is started.

During standby, the rotation of the cylinder is stopped in order to suppress the consumption of the battery, and power is supplied only to the minimum circuits. When recording is started from the standby state, power is supplied to each unit, the cylinder is rotated, and the cassette tape 22 is run to start recording.

[0006]

However, in the above-mentioned conventional configuration, when it is desired to immediately perform recording during standby, the cylinder is rotated by the start of recording, the cassette tape is run, and recording is started after the running is stable. It was not possible to record immediately after standby-on.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide an integrated video device capable of recording immediately while minimizing battery consumption.

[0008]

In order to achieve the above object, the present invention has a memory having a storage capacity for a plurality of screens for temporarily storing a video input signal and an audio input signal, and is read from the memory. It has a configuration including a rotary head for recording a signal and a control unit for controlling the memory and the rotary head.

[0009]

With the above construction, the video input signals for a plurality of screens are always stored in the memory, and the rotary head and tape running are controlled so that the signals read from the memory are recorded when the standby is turned on. With this, by turning on the standby, the video signals for multiple screens are read from the memory until the time when the rotary head or tape running is stabilized, and after that, the video signals input from the memory are controlled to be read continuously. At the same time, by controlling the rotary head to record the read signal, the signal at the time of standby-on can be recorded on the cassette tape.

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 an integrated video device according to a first embodiment of the present invention. In FIG. 1, the light input from the lens 11 is converted into an electric signal by the CCD 12. The process circuit 13 sets the input signal to a constant level, and then the changeover switch 14 switches between a circuit similar to the conventional one and a circuit peculiar to this embodiment. The changeover switch 14 is changed over in conjunction with the changeover switch 18. The b side of the switch is the conventional circuit. When the switch 14 is set to the a side, the A / D converter 15 converts an analog signal into a digital signal and stores the signal in the memory 16. The D / A converter 17 converts the digital signal into an analog signal. Digital signal control circuit 23
Controls reading of digital signals from the memory 16.

The encoder 19 is selected by the switch 18.
Is converted into a video signal by, and amplified by the recording circuit 20, a signal is sent to the video head 21, and recorded on the cassette tape 22. The control circuit 23 controls the recording timing.

At the recording timing, recording is started after confirming that the cylinder or tape running is stable.

When recording normally, the switches 15 and 18 are used.
Is recorded on the b side by a conventional method.

In the standby immediate recording mode, the switch 15 is used.
And 18 are switched to the side a, the input signal is always stored as video input signals for a plurality of screens, and the signal read from the memory is recorded by standby-on.

FIG. 2 shows a block diagram of an integrated video apparatus according to a second embodiment of the present invention for immediately recording a digital signal on standby. In FIG. 2, the light input from the lens 11 is converted into an electric signal by the CCD 12. The process circuit 13 sets the input signal to a constant level, and after that, A
The / D converter 15 converts the analog signal into a digital signal and stores the signal in the memory 16. The digital signal control circuit 23 controls reading of digital signals from the memory 16. Next, it is converted into a video signal by the encoder 19, amplified by the recording circuit 20, and sent to the video head 21 to record it on the cassette tape 22. Control circuit 23
Controls the timing of recording.

At the recording timing, recording is started after confirming that the cylinder or tape running is stable.

The power supply to each circuit is supplied to the minimum circuit to minimize the consumption of the battery.

[0018]

As described above, according to the present invention, the memory always stores the video input signals for a plurality of screens, and the rotary head and the tape running are controlled so that the signals read from the memory are recorded by the standby ON. By doing so, it is possible to reduce the consumption of the battery as much as possible and to immediately perform recording in standby-on.
