Description

DETAILED DESCRIPTION OF THE INVENTION The present invention reproduces a designated specific video signal from a first disk on which one field or one frame of video signal is recorded on each track, and reproduces it on a plurality of second disks. The present invention relates to a video disc editing device for selectively recording onto a predetermined disc.

In the case of conventional video disk editing devices, after checking the video signal recorded on the first disk using a monitor device, the track on which the desired video signal is recorded is traced again, and the track being played at that time is checked. The configuration is such that video signals are sequentially recorded onto the second disk.

Therefore, in conventional devices, it is necessary to repeatedly perform various operations for each video signal to record a specific video signal recorded on a first disk onto a second disk, which is time-consuming and It lacked speed and accuracy.

In particular, when editing video signals recorded on one or more first disks by re-recording them onto multiple second disks, the disks must be loaded and unloaded frequently. , the work had to become complicated.

The present invention was developed in consideration of the above circumstances, and its purpose is to enable a specific video signal recorded on the first disk to be changed by simply performing a predetermined setting operation. It is an object of the present invention to provide a video disc editing device that can selectively and automatically record onto a predetermined disc among a plurality of second discs and perform quick and accurate editing.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the editing device of the present invention. A first disk 11 is loaded on the upper left side of the box 10, on each track of which image information is recorded, in which a track address code signal and a specific keyword code signal are added to a video signal of one field or one frame. A plurality of (four in this embodiment) second disks 12A, 12R, 12C, and 12D for editing, which rotate in synchronization with the first disk 11, are loaded in the lower left row. In addition, a monitor device 13 is arranged at the upper right corner of the box 10, and at the lower right corner,
An address designation switch 14 that designates the track address of the first disc 11, a disc selection switch 15 that associates each of the second discs 12A to 12D with the keyword code signal, a recording command switch 16 that commands editing and recording, etc. are provided. be done.

FIG. 2 is a diagram showing the configuration of an electronic camera for obtaining the first disk 11, in which 17 is a camera body, 18 is a lens, 19 is an image sensor, 20 is a disk, 21 is a head, 22 is a key switch, 23
24 is a release button, 25 is a keyword code signal generator, 26 is a track address code signal generator, 27 is an adder, and 28 is a modulator. That is, the video signal obtained by the image sensor 19, the keyword code signal generated from the keyword code signal generator 25 according to the specification of the key switch 22, and the keyword code signal generated from the track address code signal generator 26 according to the position of the head 21. The track address code signals are multiplexed by an adder 27, modulated by a modulator 28, and supplied to the head 21. As a result, a video signal to which a keyword code signal and a track address code signal are attached is recorded on the disk 20.

FIG. 3 is a block diagram showing the configuration of the drive control system of this device. As shown in FIG. 3, the track address code signal generated by the address designating switch 14 is temporarily stored in the register 31. Further, the disk selection signal generated by the disk selection switch 15 is temporarily stored in the register 32.

On the other hand, the image information recorded on the first disk 11 is demodulated by the demodulator 33 and then supplied to the monitor device 13 for image display, and is also supplied to the keyword detector 34 and address detector 35. A keyword code signal and an address code signal are detected.

The address code signal stored in the register 31 and the address code signal detected by the address detector 35 are compared in a comparator 36, and when both code signals match, a stop signal is given to the drive pulse generator 37. It will be done. The drive pulse generator 37 normally supplies a drive pulse to the head sending mechanism 38 to move the head 39 one track pitch at a time in the radial direction of the disk 11, and when the stop signal is given, it stops sending out the drive pulses. and stop the head feed. Therefore,
The head 39 stops on the track where the address code signals sequentially supplied by the address detector 35 match the first specified address code signal stored in the register 31. At this time, the video signal demodulated by the demodulator 33 is displayed on the monitor device 13, and the keyword code signal thereof is detected by the keyword detector 34 and supplied to the register 32. Since the register 32 is supplied with the disk selection signal from the disk selection switch 15, the register 32 sends out a disk selection command signal corresponding to the keyword code signal to each of the disk selection rotary switches 40 and 41. Solenoid part 40A,
41A. Therefore, the rotary switches 40, 41 select the second disk, for example 12A, corresponding to the detected keyword code signal. At this time, the track selection pulse generator 42 is activated by the signal from the register 32.
A track selection pulse is applied to the head feeding mechanism 43A of the selected disk 12A. Thus, head 44A on disk 12A moves to a predetermined track.

In this state, when the recording command switch 16 is closed, the reproduced video signal demodulated via the contact 16a is modulated by the modulator 45, then amplified by the recording amplifier 46, and selected by the rotary switch 41. is supplied to the supplied head 44A. In this way, a specific video signal reproduced from the first disk 11 is recorded on a predetermined track of the disk 12A. When this recording operation is completed, a signal indicating the end of recording is given as a step-up signal from the output end of the modulator 45 to the register 31, for example, although not shown, and the next specified address code signal is sent to the comparator 36. given to one input end. For this reason, the driving pulse generator 3
7 starts operating again, the same operation as described above is performed, and the required video signal recorded on the first disk 11 is transferred to a predetermined track of a predetermined disk of the second disks 12A to 12D. recorded against. By repeating similar operations, the video signal recorded on the first disk 11 is automatically distributed and recorded on the second disks 12A to 12D.

After the editing of the image information recorded on the first disk 11 is completed as described above, if the first disk 11 is replaced with another first disk and the same operation as described above is performed, the set state can be changed. Editing and recording can be continued on the second disks 12A to 12D.

Note that the disk selection switch 15 selects the second disk 12A for the keyword code signal.
The correspondence relationship between 12D and 12D can be changed as appropriate.

In this way, in this device, by first performing a predetermined setting operation using the address designation switch 14 and the disk selection switch 15, the designated The specified video signals are automatically distributed and recorded on the plurality of second disks 12A to 12R. In other words, editing is performed automatically. Therefore, it is not necessary to perform complicated operations for each piece of image information as in the past, and moreover, editing can be performed quickly and accurately. In particular, since the image information recorded on the first disk 11 is attached with a keyword code signal that specifies the image information, there is an advantage that the image information can be easily selected and the circuit configuration can be simplified.

Note that the present invention is not limited to the above-described embodiment. For example, if the correspondence between the keyword code signal and the plurality of second disks 12A to 12D is fixed, the disk selection switch 15 may be omitted. Furthermore, since the image information includes a keyword code signal, the image information may be checked using only the signal, and the monitor device 13 may be omitted. Further, the number of second disks is not limited to four, and the number can be set arbitrarily. Furthermore, instead of the recording command switch 16, a switch that automatically closes upon completion of the setting operation may be provided. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

As explained above, according to the present invention, the image information recorded on the first disk is attached with a track address code signal and a keyword code signal for specifying the image information. Based on this, the disc to which recording is to be performed is automatically selected from among the plurality of second discs, so that by simply performing a predetermined setting operation, a specific one of the video signals recorded on the first disc can be selected automatically. It is possible to provide a video disc editing device in which a video signal is selectively and automatically recorded on a predetermined disc among a plurality of second discs, and can perform quick and accurate editing.
