DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the drawings. First, the configuration of an electronic still camera capable of recording a classification code will be described. FIG. 1 is a circuit diagram showing an example of a recording classification system of an electronic still camera. The classification code is recorded on the cue track of the floppy disk. The data recorded on the cue track is the data recording W.D. It is a system defined by G (NRZ system), and the classification code is added every time an image is recorded on an empty track. The image pickup system is composed of a lens 1, a diaphragm 2 and a CCD 3, and a signal processing circuit 4 inserts a synchronizing signal or the like into the signal from the CCD 3 to create a predetermined video signal, performs emphasis processing, and then performs FM modulation. . The recording circuit 5 adjusts the FM modulated wave (video signal) from the signal processing circuit 4 to an appropriate recording current, and then records it on an empty track by the head 15.

The CPU 6 is a CCD when the camera is activated.
The electronic shutter circuit 9 is controlled so as to send out a timing pulse such that 3 becomes a predetermined shutter speed. Further, an aperture control signal is sent to control the aperture 2 so as to obtain an appropriate aperture value, and a lens drive control signal is sent to perform focusing control of the lens 1. The CPU 6 controls the image pickup system and drives the servo circuit 11 and the motor 12 so that the floppy disk 14 rotates at a predetermined speed and phase. The NRZ writing circuit 10 is the CPU 6
In the circuit for converting the classification code sent from the NRZ signal into the NRZ signal, the NRZ signal is adjusted by the recording circuit 5 to an appropriate recording current, and then added to the cue track by the head 15.

The LCD 7 displays various states of the electronic still camera. For example, a mode display such as a classification mode, an inputted classification code and the like are displayed at the time of photographing and reproduction. The key input unit 8 includes keys for shooting and reproducing the electronic still camera, a classification mode key 8a for designating a classification code, and a classification code input key 8b for inputting a classification code. There is. In addition, a multi-mode key 8c for designating a multi-reproduction mode, a track map key 8d for displaying a track map, a classification code display key 8e for displaying a classification code corresponding to the image being reproduced, and a classification for erasing the classification code. The code erase key 8f is provided. The CPU 6 has a built-in recording unit 6a for temporarily recording the classification code, and controls the reproduction system circuit in addition to the control of the imaging system circuit as described above.

The circuit portion on the right side of the alternate long and short dash line is a portion constituting a reproducing system. When the reproduction circuit 16 receives a reproduction instruction, the reproduction circuit 16 detects the FM from the seeked track of the floppy disk 14.
After the modulated video signal is read and the FM modulated wave is demodulated, de-emphasis processing is performed to restore the original video signal. When the NRZ signal of the classification code is read from the cue track, it is sent to the NRZ reading circuit 17. N
The RZ reading circuit 17 inversely converts the NRZ signal, demodulates the original signal, and sends it to the CPU 6. The CPU 6 can display the read classification code on the LCD 7 for each track and display the track map. Memory control circuit 1
8, A / D converter 19, memory circuit 20, and D / A converter 21 are circuits used for multi-reproduction.

Next, the operation of recording the classification code at the time of shooting will be described. When a main switch (not shown) is turned on, the camera is activated and automatically enters the photographing mode. CP
U6 determines whether or not a floppy disk is loaded, and whether or not the loaded floppy disk is recordable. If both are acceptable, then it is determined whether the classification mode key 8a is pressed. When the classification mode key 8a is pressed to specify the classification mode, the classification code input key 8b accordingly inputs the classification code of the subject to be photographed. This classification code is recorded in the temporary recording section 6a of the CPU 6 and displayed on the LCD 7 to prepare for recording the classification code. Next, when a release button (not shown) is pressed, an image is recorded on a predetermined track of the floppy disk 14 via the image pickup system, the signal processing circuit 4, and the recording circuit 5, and the classification code held in the temporary recording section 6a. Is the NRZ writing circuit 1
0, and is recorded on the cue track of the floppy disk 14 via the recording circuit 5. When the photographing is completed and the main switch is turned off, the photographing is completed. When the main switch is not turned off, the next photographing preparation operation is performed.

FIG. 2 is a diagram showing an example of the track map displayed on the monitor screen. When the track map key 8d is pressed after the playback mode is specified and it is determined that the image on the floppy disk can be played, the CP
U6 seeks the cue track and displays the classification code on the monitor screen (not shown) via the reproducing circuit 16. When the classification code is specified, the classification display is made in the corresponding portion of the track map. In FIG. 2, flower, tree, and house classification codes are recorded from 1 to 9 tracks for video recording, and video recording is performed from 10 to 14 tracks, but classification code is not recorded. 2 to 19 tracks have classification code and video recording, but the classification specification code is not specified.
It is shown that the 0th track and the following tracks are unrecorded tracks.

Next, the classification code dubbing method according to the present invention will be described with reference to FIGS. 3 and 4. FIG. 3 is a circuit diagram showing an embodiment of an editing machine to which the classification code dubbing method according to the present invention is applied. In FIG. 3, the servo circuit 23,
The functions of the motor 24, the head drive circuit 25, the reproduction circuit 29 and the NRZ reading circuit 30 are the servo circuit 11, the motor 12, the head drive circuit 13, the reproduction circuit 16 and N of FIG.
This is the same as that of the RZ reading circuit 17. Between the head output of the floppy disk 26 and the internal recording device 28,
The dubbing circuit 27 is connected. Dubbing circuit 27
Is A for floppy disk 26 and B for internal recording device 28
Then, switching of A → B and A ← B is performed according to the dubbing direction. The CPU 22 has a temporary recording unit 22b for temporarily recording the designated classification code, and a classification code management unit 22a for managing the classification code corresponding to the image recorded in the internal recording device. The key input unit 31 connected to the CPU 22 includes a classification mode key 31c, a classification code specifying key 31a for specifying the dubbing order, and a direction specifying key 31b for specifying the dubbing direction.

FIG. 4 is a flow chart for explaining the editing operation of FIG. When the main switch (not shown) is turned on, the circuit of the entire editing machine is activated. The CPU 22 determines whether or not the classification mode key 31c is pressed (ST1). If the classification mode is not designated, the mode shifts to another mode. If the classification mode is designated, the dubbing order can be designated by selectively designating the classification code (ST2). When the classification code is selected with the classification code designation key 31a and the dubbing order is designated, C
The PU 22 records the information in the temporary storage unit 22b and determines which direction the dubbing direction is designated (ST3). If the direction designation key 31b is designated as A → B, the process proceeds to step 4, and the dubbing circuit 27
Is controlled to switch from A to B. On the other hand, if the direction designation key 31b is designated as A ← B, the process proceeds to step 10, and the dubbing circuit 27 is switched to A ← B.

Here, the case of proceeding to step 4, that is, the case of dubbing from the floppy disk to the internal recording device 28 will be described. When the floppy disk on which an image is recorded with the classification code specified is inserted (ST4), the CPU 22 determines whether or not the floppy disk can be reproduced (ST5). If no floppy disk is actually inserted or no image is recorded on any track, a warning is displayed. When the floppy disk can be reproduced, the cue track is sought, and the map of the classification code (NRZ signal) is reproduced by the reproducing circuit 29.
The data is read by the NRZ reading circuit 30 via (ST6). C
The PU 22 detects a video track having the same classification code as the designated classification code by referring to the map of the classification code read from the cue track, and controls the servo system to seek the tracks in order. Then, it is determined whether or not the internal recording device 28 can record before reading the video from the track to be sought (ST7).
If there is no recording capacity in the internal recording device 28, a warning to that effect is displayed.

When the internal recording device 28 is recordable, images are read out in the order of detected tracks and recorded in the internal recording device 28 (ST8). At this time, the classification code management unit 22a records the classification code corresponding to the video recorded in the internal recording device 28, and manages the recorded contents of the internal recording device 28. After all the images of the specified classification code on the floppy disk have been dubbed, if the floppy disk is to be replaced, the process returns to step 4 and the same operation as above is repeated. If the floppy disks are not replaced, the dubbing is completed (ST9).

Next, the case of proceeding to step 10, that is, the case of dubbing from the internal recording device to a floppy disk will be described. The CPU 22 specifies the classification code and inserts a recording floppy disk (ST10).
Then, it is judged whether or not the floppy disk can be recorded (ST11). If there are no broken nails or empty tracks,
A warning indicating that recording is not possible is displayed. If the floppy disk can be recorded, the classification code management unit 22
The image storage area having the same classification code as the designated classification code is accessed in order by referring to the map of the classification code of a, the contents are read and recorded on the floppy disk (ST12). When there are no tracks to be recorded on the floppy disk and there is still an image to be dubbed in the internal recording device 28, when the floppy disk is replaced, the process returns to step 10 to continue dubbing. When the floppy disks are not replaced, dubbing is completed (ST13, 14).

The example of dubbing a floppy disk in which the classification code is recorded on the cue track has been described above. However, the classification code can be recorded in the user's area in addition to this. Similarly, it is possible to dubb the floppy disk recorded on the disc using the classification code. In such a case, instead of the NRZ reading circuit, a 13 fh PLL circuit that creates a carrier wave of 204 kc by a phase locked loop and 2
It is necessary to provide a DPSK circuit or the like that shifts the phase of the carrier wave of 04 kc in correspondence with the classification code. Also, FIG.
Examples of the internal recording device used in this embodiment include semiconductor memory, HDD, optical disk, and the like. Further, the recording device does not have to be provided inside and may be connected externally. Alternatively, a floppy disk may be used as the internal recording device. When using a digital recording device such as an HDD or an optical disk, it is necessary to provide an A / D and D / A converter.

[0018]

As described above, the present invention is constructed so that an image on which a classification code is recorded can be automatically edited and dubbed by using this classification code. Therefore, editing work becomes simpler than before and, for example, even when subjects of the same classification code are recorded across multiple floppy disks,
There is an effect that the shooting date and time can be centrally managed by dubbing to the recording device with the classification code.
