Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic still camera and its playback device effective for recording and playing back video signals on a rotating magnetic sheet such as a video floppy, and an editing device using the same. It is something.

BACKGROUND ART Conventional electronic still camera editing devices use a pair of an electronic still camera that is dedicated to recording video signals, etc., and a playback device that is used only for playback or a recording and playback device that has both recording and playback functions. configured. Then, the electronic still camera records the video signal etc. on a video floppy, which can then be displayed on the screen of a television receiver (hereinafter referred to as ?I) using a playback device or recording/playback device, or printed as a hard copy using a printer. It is now possible to take it.

Here, it is rare for a user to want to save everything that has been recorded, and in reality, only the necessary signals
If you want to record a new signal by keeping the old tracks and erasing the others, or if you want to record only the necessary signals to another video floppy, erase all the old video floppy and record a new, different signal. There are many cases where you want to record something.

First of all, an erasing means is needed to erase the recorded signal on the video floppy, but devices with an additional recording function generally come with an erasing function, and recording/playback devices usually do not have this erasing function. have. Therefore, users generally use a recording/reproducing device as a first method to satisfy the above-mentioned wishes.

Another possible second method is to provide an electronic still camera with an erasing function, and use the electronic still camera to erase unnecessary tracks.

Problems to be Solved by the Invention However, the first method described above requires an expensive recording and reproducing device, which places a heavy burden on the user, and also requires the recording function of the electronic still camera and the recording and reproducing device. This results in the existence of two recording functions, which has the problem of being wasteful since one recording function is sufficient unless there is a special use.

In addition, in the second method mentioned above, the system configuration is good because it allows the use of an inexpensive playback device, but when erasing with an electronic still camera, the recorded contents cannot be confirmed with the viewfinder, for example. When playing back on a playback device, the user has to record in advance which track he or she wants to erase in a memo or the like and remember it until the time of erasing, which poses a problem in that the user is not comfortable using it.

Furthermore, if you want to dub to another video floppy for editing, etc., the signal played by the playback device or recording/playback device must be recorded by yet another recording/playback device, which is unreasonable. It had the problem that.

In view of these points, it is an object of the present invention to provide an electronic still camera editing device that is inexpensive and has a simple configuration, and is capable of erasing and re-recording unnecessary portions of a video floppy and dubbing editing.

Means for Solving the Problems The present invention provides a reproducing device having an output terminal for reproducing and outputting a signal recorded on a recording medium, and an erasing means for erasing part or all of the signal recorded on the recording medium. An electronic still camera comprising: an electronic still camera having an external input terminal for recording external signals; and a dubbing cable connecting the output terminal of a playback device and the external input terminal of the electronic still camera. They are an editing device and a playback device suitable for it.

According to the above-described configuration, when dubbing and editing is first performed, the present invention searches for a signal to be dubbed by playing it on a playback device, plays that signal, and transmits the signal to the electronic still camera through a dubbing cable. All you have to do is input this and record at the desired position on the recording medium attached to the electronic still camera. Further, if it is desired to erase unnecessary recording and re-record, the reproduction device reproduces the information and if unnecessary signals are found, the erasing means erases those portions of the signals. and,
If the recording medium is attached to the electronic still camera again, the desired signal can be recorded at the erased position.

Therefore, there is no need for an expensive recording and reproducing device as in the past, and unnecessary recordings on the recording medium can be erased using an inexpensive and simple configuration consisting of only an electronic still camera, a reproducing device, and a dubbing cable. can be easily re-recorded and edited by dubbing.

It should be noted that the playback device 2 does not have a recording function for recording signals on the video floppy 1.

FIG. 2 is a block diagram showing a playback device, and FIG. 3 is a block diagram showing an electronic still camera.The operation will be explained using FIGS. 1 to 3.

First, when normal playback is performed on the playback device 2, the power switch 3 is turned on and the video floppy 1 is inserted into the insertion slot 12.The signal recorded on the video floppy disk 1 is played back by the head 101. Since the switch ON 102 is connected to the head amplifier 103 side according to the command from the control circuit 112, the signal is transmitted to the head amplifier 10.
Amplified at HPF 105. BPF108. LPF
10, the luminance signal Fl is sorted into 1/1 chrominance signal component and ID signal component, and each luminance signal demodulation circuit 108 and chrominance signal demodulation circuit 109. The signals pass through the ID demodulation circuit 110 and are output to the output terminal 11, and are combined in the mixing circuit 111 and output to the video output terminal 10 as a decoded signal. This video output screen 10 is connected to the monitor T'''715 with the video cable 14, so the playback screen can be viewed on the monitor TV 15.Then, the tracks of the video floppy 1 are sent to other playback screens. If you want to view the image, press the feed switch 4 or 6 or turn the jog knob 9, and the signal from the operation unit 114 is input to the control circuit 112, and the drive means 113 is driven by the command from the control circuit 112. The driver 101 moves to the desired track position and plays the track.

Next, if you want to erase unnecessary track parts,
First, search for an unnecessary signal in the above-mentioned reproduction, and press the erase switch 6 while the signal is being reproduced. The signal from the operation section 114 is input to the control circuit 112, and according to the command from the control circuit 112. The switch person 102 switches to the erase signal generation circuit 104 side 9, and at the same time the erase signal is transferred from the erase signal generation circuit 104 to the 7 do 1 side.
Flow elimination is performed at 01. Then, other unnecessary parts are similarly erased 11 times. Also, if you want to erase all tracks instead of some, you can erase all tracks...
When the erase switch is pressed, the above-mentioned erasing operation is carried out, and commands are sequentially given to the drive means 113 from the control circuit 112, and while erasing, the I/D 101 is moved to the inner and outer peripheries of the video flow...JP 1. You can erase all the tracks by moving them one by one.

If the video floppy 1 on which part or all of the data has been erased is mounted on the electronic still camera 16, recording can be performed again, so that the video floppy can be used without wasting anything.

If you want to take normal pictures with the electronic still camera 16, set the mode changeover switch 21 to the camera mode side.
The color signal processing circuit 205 side is connected to the color signal processing circuit 205 side.

On the other hand, in the initial state with video floppy 1 installed, it is
The Sochi B215 is connected to the envelope detection circuit 217 side, and drives the driving means 219 in response to a command from the control circuit 218 to sequentially move the head 216 to determine which tracks have been recorded by the envelope detection circuit 217. This information is stored in the memory 221, and the /do stops at the position of the unrecorded track and waits for a recording command to arrive. When the release switch 19 is pressed, the shutter/aperture 202 is controlled to a predetermined value according to the brightness of the subject by a command from the control circuit 218 via the operating cloth, and the light from the subject is directed to the lens 18 and the shutter. - Passes through the aperture 202 and enters the image sensor 203, and the image sensor 2
The signal from 03 passes through the luminance signal processing circuit 204 and the color signal processing circuit 206, respectively, and is switched to the mode changeover switch 2.
1 through the FM modulation circuit 209 and the FM modulation circuit 21
0 and enters the same mixing circuit 213 again. here,
For the date, the ID signal such as information is sent from the ID generation circuit 211 to FM.
It also enters the mixing circuit 213 via the modulation circuit 212. At this time, the switch B215 is connected to the recording amplifier 214 side according to a command from the control circuit 218, and the signal output from the mixing circuit 213 is amplified by the recording amplifier 214, flows to the head 216, and is recorded on the video floppy 1. become. When this recording is completed, a command is sent from the control circuit 218 to the driving means 219 to drive the head 216.
moves to the next unrecorded track position and waits, and when the release switch 19 is pressed again, the same operation is performed to record the next occurrence.

Next, if you want to perform dubbing editing, first connect the output terminal 11 of the playback device 2 and the external input terminal 2o of the electronic still camera 1q with the dubbing cable 22, playback on the playback device 2, and then perform dubbing. Select a signal. On the other hand, the mode changeover switch 21 of the electronic still camera 16 is switched to the external input terminal 20 side. Also, when the Video Flo Novy-1 is attached to the electronic still camera 16, the recorded tracks are checked and the information is memorized, and the unrecorded tracks, The hood 216 is stopped and waiting at the position of the button. When the release switch 19 is pressed here, among the signals sent from the playback device 2, the luminance signal, the color difference R-Y signal, and the color difference B
The -Y signal passes through the mode changeover switch 21 and enters the mixing circuit 213 via the FM modulation circuits 209 and 210. In this case, if it is just an external input terminal, a video signal will suffice, but if it is a video signal input, a circuit that divides it into a luminance signal, a color difference R-Y signal, and a color difference B-Y signal is required on the electronic still camera 16. It becomes necessary internally and grows larger.

On the other hand, the ID signal sent from the playback device 2 is first read by the control circuit 218, and information such as a new message that the user wants to add is added to it, and the signal is sent via the ID oscillation circuit 211 and the FM modulation circuit 212. The signal then enters the mixing circuit 213 and is mixed with the aforementioned signal. The signal is then amplified by the recording amplifier 214 and recorded in the head 216 in the same way as during normal photographing. When this recording is completed, the driving means 219 is driven by a command from the control circuit 218.
is operated to move the head 216 to the next unrecorded track position and wait. The external input terminal 2o still includes the control signal input/output terminal 201, but in this case, a command to advance the track position of the playback device 2 to the next one is simultaneously issued from the control circuit 21B, and the dubbing cable 22 This command is input to the control circuit 112 of the playback device 2 through the control signal input/output 116 terminal of the output terminal 11 of the playback device 2, and the driving means 113 is operated to move the head 101 to the next track and receive the next signal. It is designed to play. In other words, if you want to dub continuously from a certain track on the master video floppy installed in the playback device 2, you only need to press the release switch 19 on the electronic still camera 16 one after another, making the operation very easy. It is. If you want to select a signal to be dubbed randomly rather than continuously, press the feed switch 4.5 or turn the jog knob 9 to play the desired track, then repeat the process of pressing the release switch 19 in sequence. .

Although dubbing is fully possible in the above manner, in this embodiment, a dubbing switch 8 is provided in the playback device 2'. This will be explained below. This corresponds to the release switch 1catcm during dubbing, and the selection of the desired signal for dubbing on the playback device 2, the installation of the video floppy on the electronic still camera 16, and the waiting at the unrecorded position of the throat 216 are completed. At this point, when this dubbing switch 8 is pressed, the control circuit 112 outputs the output terminal 11.
The same command as when pressing the release switch 19 is sent to the control circuit 218 of the electronic still camera 16 through the control signal input/output 1115 terminal of the dubbing cable and the control signal input/output 206 terminal of the external input terminal 20. A recording is made. After recording, the head 216 moves to the next unrecorded track position and waits, and the control circuit 21 of the playback device 2 is activated as in the case of dubbing recording using the release switch 19.
Since a command is sent back to 8 to move to the next track, the reproducing device 2 reproduces the next track.

Therefore, if you want to dub continuously, all you have to do is press the dubbing switch 8 one after another.It is very easy to operate, and if there are no unrecorded tracks and recording is no longer possible, you can switch the dubbing record/notch. Since the track on the playback device 2 does not advance to the next one even if the button is pressed, it is convenient to be able to determine this fact.

In this embodiment, the electronic still camera 16 is provided with a mode changeover switch 21 to switch between recording during shooting and recording of external input during dubbing. It may be configured such that if the external input terminal is connected to the external input terminal, the external input is recorded. In addition, the playback device 2 or the electronic still camera 1e
If you press this switch, the dubbing will be recorded and the track moving operation will be automatically repeated in sequence, and the dubbing video floppy with exactly the same recording as the recording on the master side video floppy will be created. It is also possible to have a configuration that allows easy creation of.

As described in detail, according to the present invention, it is possible to erase and re-record unnecessary parts of a video floppy and to edit dubbing without the need for an expensive recording/reproducing device and with an inexpensive and simple configuration. The practical effects are great.
