In the figure, the image pickup device 1 is, for example, C
The imaging signal output from the imaging device 1 is subjected to noise removal processing in a correlated double sampling circuit (CDS) 2,
After the gain is adjusted by the automatic gain adjustment circuit 3, the analog
It is converted into a digital signal by a digital (A / D) converter 4. The imaging signal converted into the digital signal is subjected to various processing such as YC (luminance / color) separation processing, contour emphasis processing, white balance, and gamma correction in the camera signal processing circuit 5, and is converted into a digital luminance signal (Y). , And a digital color difference signal in which the color difference signals (RY, BY) are arranged in dot sequence.

Here, an operation (normal recording operation) when the image pickup signal output from the image pickup device 1 is recorded on the tape 24 will be described.

The digital luminance signal generated in the camera signal processing circuit 5 is input to the Rec input terminal of the selector 6 and sent to the blanking adding circuit 6 via the selector 6, where the blanking signal is added. . Also,
The digital color difference signal generated by the camera signal processing circuit 5 is input to the Rec input terminal of the selector 10 and
The signal is sent to the modulation circuit 11 via the selector 10 and subjected to burst addition and modulation processing. The processed luminance signal and color difference signal are respectively digital-analog (D /
A) The signal is converted into an analog signal by the converter 8 or 10;
The image is displayed on the finder 14 as a real-time image via the low-pass circuit 9 or 13. Low-pass circuits 9 and 1

Data is generated. This data is sent to the image data input / output unit 16 via the selector 35. The data sent to the image data input / output unit 16 is temporarily stored in a frame memory (FM) 17 and then subjected to an encoding / decoding process 18.
And sequentially written in the track memory (TM) 19. When adopting the DV format, for example,
In the NTSC, a signal of one frame is formed by ten tracks as shown in FIG. The data written to the track memory 19 is taken out by the memory I / F 20 and written to the working track memory 26 via the bus. The written data is added with an error correction code by an error correction circuit 22, output as an analog recording signal from an AD / DA converter 21 via a bus, and recorded on a tape 24 by a head 23. A bus connected to the memory I / F 20, the AD / DA circuit 21, the error correction circuit 22, and the work track memory 26 is controlled by a bus controller 25. By performing the above operation, a video signal is recorded on the tape 24.

In this embodiment, a camera-integrated VTR
Is configured to generate a reduced screen as one multi-screen at the start of recording. Here, the multi-screen generation operation will be described. FIG. 2 is a conceptual diagram showing a configuration of a multi-screen displayed on the finder 14 in the present embodiment. As shown in FIG. 2, in the present embodiment, the image is divided into three in the horizontal direction and four in the vertical direction.
A case will be described in which a multi-screen of 12 divisions is displayed, but the number of divided screens is not limited to this.

When the start of recording is designated by the operator using the input key 34, a command is sent from the microcomputer 33 to the memory control circuit 31 and the recording / reproduction control circuit 32.

The memory control circuit 31 stores the track memory 19
And controls the operation of the track memory 19, such as writing data to the track memory 19 and fetching data written in the track memory 19, in accordance with instructions from the microcomputer 33. In the normal recording operation described above, the data sequentially encoded by the encoding / decoding circuit 18 and written to the track memory 19 is decoded by the encoding / decoding circuit 18 before being recorded on the tape 24, and is once decoded. It is stored in the frame memory 17. The data stored in the frame memory 17 is sent to the image reduction circuit 27 under the control of the image data input / output unit 16, and the image reduction circuit 27 performs filtering for suppressing aliasing noise caused by data thinning.

The filtered data is sent to the frame memory 28 via the selector 36. The frame memory 28 is connected to a memory control circuit 31, and the frame memory 2 is controlled by the memory control circuit 31.
8, data to be displayed on the split screen # 1 in FIG. 2 is written.

Here, the frame memory 28 has n addresses in the horizontal direction and m addresses in the vertical direction.
It has a memory capacity equivalent to one frame of a TV signal. For simplification of the following description, n is a multiple of 3 and m is a multiple of 4.

FIG. 3 is a diagram for explaining the write timing when an image of one screen extracted from the track memory 19 is written in the frame memory 28.

[0062] As shown in FIG.
In a two-split screen, the horizontal direction is 3 for one screen.
Only one pixel per pixel and one line per four lines in the vertical direction are thinned out and written. That is, in the image # 1 shown in FIG. 3, only the data corresponding to the pixel surrounded by the frame is written to the address of the frame memory 28 shown in the frame, and the data No corresponding data is written. When the address reaches (0, n / 3-1), (0, n / 3) becomes the head address of the data of image # 2, so that the data of screen # 1 is not written, and (0, 1) Is written. When the address reaches (m / 4-1, n / 3-1), the writing of the data of the reduced image # 1 displayed on the screen # 1 is completed. By intermittently writing the image data in this manner, the image data is thinned out, and the image reduction circuit 27 generates a reduced image forming a multi-screen.

The track memory 19 has a selector 36
When writing the reduced image # 1, the start address (0,0) of the frame memory 28 corresponds to the start position of the image # 1 sent from the track memory 19 when writing the reduced image # 1. The track number to be written is written via the selector 36. FIG. 4 is an explanatory diagram showing tracks in the track memory 19 when the DV format is adopted. Each image data shown in FIG. 4A stores a subcode as shown in FIG. 4B. It comprises an area (area A), an area for storing video signals (area B), an area for storing audio signals (area C), and an area for storing ITI (area D). As shown in FIG. 4C, an area for storing the subcode includes a sync area for storing a synchronization signal, an area for storing an ID code used for processing to be described later, and the like. It consists of a subcode data area for writing auxiliary data such as the elapsed time of a scene and a scene title, and an area for storing a signal (parity) for error correction during reproduction. The track numbers written in the frame memory 28 are as shown in FIG.
It is written in the ID code area in the subcode area of the DV format shown in (c).

Next, when recording of the image # 2 is started, the track number of the head position of the image # 2 is stored in the address (0, n / 3) corresponding to the divided screen # 2 in FIG. Is written, and then the data of the image # 2 is intermittently written to the frame memory 28 by the above-described procedure. After that, according to the number of recording starts, the frame memory 2
The data of the images # 3, # 4,... Is intermittently written to the addresses corresponding to the eight divided screens # 3, # 4,.

FIG. 5 shows the recording start trigger (REC trigger), the VD signal added to the head of the TV signal, the FLD signal for identifying the field of the TV signal, and the frame memory 28 in such data writing. 5 is a timing chart showing output timing of a write enable signal WRITE. Here, the output interval of the signal VD is 1/60 second.

In the same figure, the input key 34
Is operated and the recording start trigger is output, the first rising edge of the VD signal after the trigger and the signal FL
The time when D rises from the LOW level to the HIGH level is detected as the head of the frame, and data writing to the frame memory 28 is started from the detected head of the frame. Writing data to the frame memory 28
This is performed while the write enable signal WRITE is rising. After the data writing of the reduced image corresponding to the image # 1 is completed, the image #
1 is recorded on the tape 24 by the normal recording operation described above. Thereafter, when the input key is again operated by the operator to output a recording start trigger, the V immediately after the trigger is output.
At the D output timing, the write enable signal WRITE rises for a predetermined period, and the image # is stored in the frame memory 28.
The data of the reduced image corresponding to No. 2 is written, and then the image # 2 written in the track memory 19 is recorded on the tape 24. After this, images # 3 and # 4
Similarly, the reduced image corresponding to
After the reduced image for multi-screen display is written to the frame memory 28, the image data written to the track memory 19 is recorded on the tape 24 by the normal recording operation described above.

When the operator operates the input key 34 to designate power off, the microcomputer 33 sends a command to the memory control circuit 31 and the recording / reproduction control circuit 32. Under the control of the memory control circuit 31, the data in the frame memory 28 forming the multi-screen is
5. The image data is temporarily stored in the frame memory 17 via the image data input / output circuit 16. The procedure for recording the reduced image data on the tape 24 is the same as that in the normal recording operation described above, but when the data is stored in the track memory 19, the last address written in the frame memory 28 is stored in the memory control. This is sent from the circuit 31 and this is shown in FIG.
Are stored in the subcode area shown in FIG. The address written in the subcode area is used to determine the address to be written to the frame memory 28 when the power is turned on next and recording starts. After all of these operations are completed, the power is actually turned off.

FIGS. 6 and 7 are flowcharts showing the operation procedure of generating a reduced image constituting a multi-screen at the start of the above-described recording and recording the reduced image generated up to that time on the tape 24 when the power is turned off. .

When the operator inputs an instruction to start recording with the input key 34 (step S10), the number of multi-screen writing display screens is set to a predetermined number N (N = 1 in the above example).
2 is set (step S20), and it is determined whether or not the screen number i generated at the time of the current recording is N or less (step S30).

Here, when the image number i is equal to or less than N, it is determined whether or not it is the head of one frame constituting the TV signal to be written, that is, the VD signal constituting the TV signal shown in FIG. Then, it is determined whether or not it is the rising timing (t) of the FLD signal (step S4).
0), if not at that timing (t), the next VD
A standby state waits for the timing when the signal and the FLD signal rise (step S50). If it is the above timing, the track number corresponding to the image is written as ID information to the ID code area in the subcode area of the frame memory 28 via the selector 36 (step S60), and the reduced image is converted to the image reduction circuit 27. To selector 3
6 (step S70). And
After "1" is added to the code i indicating the image number (step S80), the data written in the track memory 19 is recorded on the tape 24 (step S90).

After the operator instructs a pause with the input key 34 and the recording operation is completed (step S10).
0), it is determined whether or not an instruction to turn off the power has been input (step S110), and if not, the processes of steps S10 to S110 are performed again.

If it is determined in step S110 that a power-off instruction has been input, all data written in the frame memory 28, that is, all reduced images are read out (step S120), and the track memory 19 is temporarily stored. Is written to. At this time, the last written address is sent from the memory control circuit 31 as described above, and this is recorded in the subcode area (step S13).
0) Then, the data stored in the track memory 19 is recorded (recorded) on the tape 24 (step S14).
0).

With the above processing, the reduced image for multi-screen display is recorded on the tape 24 when the power is turned off.

Next, the case where the power is turned on again and the reproduction is performed will be described. FIG. 8 is a flowchart showing an operation procedure when a multi-screen is displayed when the power is turned on again, and when one of the multi-screens is selected by the operator, the selected screen is automatically located.

As described above, when the power is turned off, the last address written in the frame memory 28 is written as a subcode, and at the same time, the fact that the multi-screen has been written on the tape is written as a subcode. Therefore, in this state, when the power is turned on again by the operator and the “reproduction start” instruction is input by operating the input key 34 (step S210), the power supply immediately before the power supply among the images recorded on the tape 24 is output. When turned off, a portion where the reduced image forming the multi-screen is written is searched (step S220).

When the reduced image is retrieved as a result of the retrieval, the data is read by the head 23. Head 23
(Analog signal) read by AD /
The signal is converted into a digital signal by the DA converter 21 and is sequentially written to a predetermined address of the working track memory 26. The written digital signal is sent to the error correction circuit 2
2 is subjected to error correction processing, and is sequentially written to the track memory 19 by the memory I / F 20. The signal read from the track memory 19 is decoded by the encoding / decoding circuit 18 and is temporarily written to the frame memory 17.

The signal read from the frame memory 17 is written into the frame memory 28 by the image data input / output unit 16 via the image reduction circuit 27 and the selector 36 (step S230). At this time, the image reduction circuit 2
7 does not work, only passes the signal.

The signal written in the frame memory 28 is read out and sent to the YC separation circuit 3 through the selector 29.
Sent to 0. In the YC separation circuit 30, the digital luminance signal and digital chrominance signal multiplexed at the time of recording are synchronized. These signals are sent to the finder 14 via the selectors 6 and 10, and are displayed as a multi-screen (step S240). The processing until the image is displayed on the finder 14 via the selectors 6 and 10 is performed in real time on the finder 1 in the normal recording operation described above.
4 is the same as the process for displaying the information in the area No. 4.

However, when the signal read from the frame memory 28 is displayed on the viewfinder 14, it is uncomfortable to display a portion of the screen where the track number is written. By generating the mask signals HMASK and CMASK shown in FIG. 2, the track number is masked.

In this state, the operator presses the input key 34
, One of the reduced screens on the finder 14 (screen #
When i) is selected (step S250), the microcomputer 33 sends the image number (#i) of the selected reduced image to the recording / reproduction control circuit 32. The recording / reproduction control circuit 32 controls the frame memory 28
Of the image #i corresponding to the selected screen number is read out (step S260), and the tape 24 is forwarded to the recording / reproduction control circuit 32 via the track memory 19 or While rewinding, the track number of the tape 24 is sent (step S270).

Then, the track number read from the frame memory 28 is compared with the track number sent from the tape 24, and it is determined whether or not they match (step S280). If they do not match, the comparison of both track numbers is repeated until they match.

If it is determined in step S280 that the track number read from the frame memory 28 matches the track number sent from the tape 24, a desired image is reproduced by the above-described method and the finder 1 is reproduced.
4 is displayed (step S290).

As described above, according to the present embodiment, at the start of recording, a reduced image forming a multi-screen is generated prior to recording of an image, and when the power is turned off, each reduced image is generated together with the reduced image. If the track number on which the corresponding image is recorded is sub-coded and recorded on the tape 24, when the power is turned on again and the reproduction is started, the multi-screen is displayed on the finder 14 and displayed to the operator. A desired image can be automatically searched for by a simple operation of selecting one of the multi-screens. Therefore, an effect is obtained that the user can automatically locate the reproduction start point of a desired image without complicated operations and without the user preparing media other than the tape 24.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG.

Then, the reduced image is recorded on the tape 24 in the same manner as in the normal recording operation described above.

In the above-described first embodiment, an image before reduction is once written in the track memory 19, and then a reduced image is generated. Then, the created reduced image is written together with the track number in the frame memory 28 for multi-screen. In this embodiment, the reduced image is written from the YC multiplexing circuit 15 to the frame memory 28 via the selectors 35 to 37, and the track number is generated by the recording / reproduction control circuit 32. Is written to the frame memory 28 via the.

The other configuration and the operation at the time of image recording and image reproduction are the same as those of the first embodiment, and the detailed description is omitted here.

As described above, when the image recording is started, the image forming the multi-screen is intermittently stored in the frame memory 28, and when the power is turned off, a reduced image is generated and recorded on the tape 24. However, as in the first embodiment described above, the tape 2 can be used without complicated operations.
An effect is obtained that the reproduction start point of the desired image can be automatically located without the user preparing any media other than the media No. 4.

The storage medium storing the program code of the software for realizing the functions of the first or second embodiment is supplied to the apparatus, and the computer (or CPU, MPU) of the apparatus stores the program in the storage medium. It goes without saying that the object of the present invention is also achieved by reading and executing the program code thus set.
