Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention records moving picture information and digital signals in different areas on a magnetic tape, for example.

2. Description of the Related Art As an apparatus for recording a video signal on a recording medium, for example, a magnetic recording medium, for example, a still image video signal,
That is, a so-called electronic still camera that records a video signal for one field or one frame on a so-called still video floppy, or a so-called camera-integrated 8 mm video tape recorder (hereinafter referred to as a camera-integrated 8 mm VTR) that records a video signal of a moving image on a magnetic tape, for example. ) Etc. are known.

For example, in a camera-integrated 8 mm VTR, a magnetic tape is placed around the so-called rotary head drum 211.
A pair of heads wound at an angle of 180 degrees (hereinafter referred to as a rotary head) helically scans the magnetic tape to form oblique tracks 81 on the magnetic tape 80, as shown in FIG. .. Then, in the video area 82 corresponding to 180 degrees of the rotary head drum of each track 81, the luminance signal is FM-modulated, the carrier color signal is converted to a low frequency, and the audio signal is FM-modulated.
A tracking signal for tracking servo, for example, a pilot signal for so-called ATF (Automatic Track Finding) control is frequency-multiplexed and recorded. In addition, the remaining rotary heads of each track 81
PCM audio area 83 corresponding to about 30 degrees of drum
Is subjected to so-called cross-interleave code processing for error correction, and then recorded with a sync signal, parity, ID, etc. added thereto. It has become so. A fixed head scans on both sides of the magnetic tape 80 to form a cue track 84 and an audio track 85. The cue track 84 records, for example, the address of the recorded contents and the cue signal used for the beginning of the recording, and the audio track 85 records, for example, after-recording (after recording).
An audio signal for recording is recorded.

Here, for example, in the above-mentioned 8 mm VTR, it is considered to record and reproduce not only a voice signal but also a digitized still picture image signal in the PCM audio area 83. The still image video signal in this case is, for example, a still image video signal captured by pressing a shutter button for still image recording in addition to a normal recording button in a VTR with a built-in camera.

In the case of shooting and playing back a moving image with the above-mentioned camera-integrated 8 mm VTR, the horizontal-to-vertical ratio (aspect ratio) is set to, for example, 1 in consideration of the range in which the human visual field naturally fits.
It has become possible to shoot an image as 6: 9, reproduce it, and display it on a monitor with an aspect ratio of 16: 9.

[0006]

By the way, the aspect ratio information at the time of shooting a moving image of the camera-integrated 8 mm VTR as described above is discriminated on the reproducing side by means such as superimposing it on a V blank at the time of shooting, for example, A video shot at 16: 9 can be played back at 16: 9, but a method that allows the playback side to determine the aspect ratio information when shooting a still image is
It wasn't there yet. Therefore, when reproducing a still image shot with an aspect ratio of 16: 9, for example, an aspect ratio of 4: 3.
On the monitor, a part of the captured still image may not be reproduced, or the captured still image may be distorted.

The present invention has been made in view of the above-mentioned circumstances, and the aspect ratio of the monitor is automatically switched by recording the aspect ratio information at the time of photographing, detecting it at the time of reproduction, and sending it to the monitor. An object of the present invention is to provide a video signal recording device and a reproducing device which can be realized.

The magnetic tape 1 has the same tape format as the magnetic tape 80 shown in FIG. 7, for example. That is, the track obliquely formed on the magnetic tape 1 by the helical scanning of the rotary head 55 is divided into a video area and a PCM audio area, a moving image is recorded as an analog video signal in the video area, and the video is stopped in the PCM audio area. Images and sounds are recorded as digital signals.

For example, when the user sets the still image shooting mode in the function control circuit 61, the system controller 62 detects a control signal corresponding to the setting and controls each unit to operate in the still image shooting mode. To do. When the shutter is operated, the shutter signal sent through the terminal 65 is detected every time the shutter is operated, and one frame or one field of the video signal obtained by photographing the subject with the camera unit 10 is stopped. The image signal is recorded in the PCM audio area of the magnetic tape 1.
At this time, the lens 11 is controlled to switch the aspect ratio of the photographed still image according to the aspect ratio selected by the function control circuit 61. Therefore, the still image recorded in the PCM audio area of the magnetic tape 1 is a still image having one aspect ratio among the plurality of aspect ratios selected by the function control circuit 61. The system controller 62 detects a control signal (aspect ratio information) corresponding to the aspect ratio set in the function control circuit 61, and supplies it to the PCM signal processing circuit 33 via the aspect ratio information adding section 64. .. This PCM signal processing circuit 33 adds the same aspect ratio information as at the time of shooting to the still image data from the still image signal processing circuit 32.

Here, the aspect ratio information adding unit 64
A method of adding aspect ratio information to still image data by the PCM signal processing circuit 33 and recording it on the magnetic tape 1 will be described.

Here, in a system for recording and reproducing a digital still image, PCM audio (8 bit-PCM and
The format using the ID is defined according to Hi8-PCM). For example, the allocation of PCM-ID word in Hi8-PCM is ID0 used in 8bit-PCM.
7 to 7, IDs 8 to 23 are newly defined. Table 1 shows the definitions of Hi8-PCM up to ID16. In Table 1, ID0 is an identification code for identifying the PCM audio signal (Audio) recorded in the PCM audio area and other digital signals (Others). Further, since each of ID8 to ID10 is composed of 2 bits, it is 6 bits as a whole. In other data recording modes (Others), the type of data of a digital video signal of a still image recorded in the PCM audio area can be selected. This is an identification code for identification. The ID 11 is an identification code that identifies, for example, of the still image digital image signals, the still image signal is in a mode called the basic A system that can be reproduced by any manufacturer's VTR. The ID 16 is an identification code for identifying the recording start and end positions of the recorded digital video signal, the type of the digital video signal, the recording information (for example, the aspect ratio) of the digital video signal in the still image basic mode.

[0030]

[Table 1]

Table 2 shows the case where the ID 16 is applied to the embodiment of the present invention.

[0032]

[Table 2]

As shown in Table 2, the aspect ratio is 4: 3.
Is defined by setting bit numbers (bit NO) 6 and bit NO7 to "1" and "0". The other "0" and "1", "1" and "1", "0" and "0" are unused (held). By defining an aspect ratio of 16: 9 using, for example, "0" and "1" in this reserved state, in the VTR of this embodiment, the aspect ratio is 4: 4.
Information with aspect ratios of 3, 16: 9 can be recorded separately.

Next, a method of reproducing the aspect ratio information recorded on the magnetic tape 1 by the VTR which is an embodiment of the video signal recording / reproducing apparatus according to the present invention will be described. In FIG. 1, the still image data recorded in the PCM area of the magnetic tape 1 is supplied to the PCM signal processing circuit 33 via the head unit 50. The PCM signal processing circuit 33 performs error correction processing on still image data and reproduces compressed data and the like. Then, the still image signal processing circuit 32 performs signal processing such as data expansion processing on the reproduced compressed data. In this way, the still image data is decoded via the PCM signal processing circuit 33 and the still image signal processing circuit 32 and stored in the memory unit 31. At this time, as described above, the PC
The aspect ratio information recorded in the M-ID is the above PCM.
It is detected by the signal processing circuit 33 or the still image signal processing circuit 32. Then, the switching operation of the changeover switch 34 is controlled according to the detected aspect ratio information. For example, the detected aspect ratio information is 16: 9.
At this time, the movable contact piece 34a of the changeover switch 34 is brought into contact with the fixed contact 34b. The video signal stored in the memory unit 31 is separated into a luminance signal and a carrier color signal via the video signal processing circuit 21. Here, as described above, the PCM signal processing circuit 33 or the still image signal processing circuit 3
When the aspect ratio information detected in 2 is 16: 9, the changeover switch 34 is controlled to superimpose DC 5V on the carrier color signal via the adder 35, and the output terminal 24,
Control monitor output from 25.

Therefore, in this embodiment, the recording device records the information corresponding to the aspect ratio of the input signal together with the still image information, the reproducing device detects the information corresponding to the aspect ratio, and the information corresponding to the aspect ratio. Since this signal is superimposed on the carrier color signal and output to the monitor, the aspect ratio of the monitor can be automatically switched.

Next, a VTR which is another embodiment of the video signal recording / reproducing apparatus according to the present invention will be described with reference to FIG. In FIG. 2, blocks having the same configurations and functions as those of the embodiment shown in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted. VTR to which the other embodiment is applied
Is an addition of an ID insertion circuit 26 for inserting the aspect ratio information (ID) into a vertical (V) blank when the aspect ratio information is 16: 9, for example.

In FIG. 2, the still image data recorded in the PCM area of the magnetic tape 1 is supplied to the PCM signal processing circuit 33 via the head section 50. The PCM signal processing circuit 33 performs error correction processing on still image data and reproduces compressed data and the like. Then, the still image signal processing circuit 32 performs signal processing such as data expansion processing on the reproduced compressed data. In this way, the still image data is stored in the PC
It is decoded through the M signal processing circuit 33 and the still image signal processing circuit 32 and stored in the memory unit 31. At this time, the aspect ratio information recorded in the PCM-ID as described above is detected by the PCM signal processing circuit 33 or the still image signal processing circuit 32. Then, the changeover switch 27 is selected according to the detected aspect ratio information.
Is controlled. For example, when the aspect ratio information is 16: 9, the ID indicating the aspect ratio information is inserted into the V blank of the video signal through the ID inserting circuit 26.

FIG. 3 shows an example of the ID code when the V blank is inserted. The data shown in A of FIG. 3 is data in one vertical scanning period. As the data, for example, 1
We are considering 6 bits. The 16 bits are divided into 4 bits to form a WORD0 (word 0), a word 1, a word 2 and a CRC code as shown in B of FIG. Word 0 among these is defined as a basic parameter relating to the video signal format as shown in C of FIG. First, bit NO. 1 of word 0 indicates aspect ratio information. For example, when "1", the aspect ratio information is 16: 9.
When it is "0", it indicates 4: 3. Also, bi
t NO. 2 shows the difference in display format when the aspect ratio is 4: 3 mode. That is, bit NO. 2 is effective only in the 4: 3 mode and transmits the display format at that time. Therefore, when bit NO. 1 is "1" (16: 9), bit N
O.2 will be ignored on the monitor side. As shown in A of FIG. 4, when a 4: 3 image is a so-called letterbox with the top and bottom cut off, when it is received by a 16: 9 monitor, the effective screen is filled up as shown in B of FIG. It is displayed by using, or is displayed by cutting the top and bottom and the side as shown in FIG. 4C. When the 4: 3 letterbox mode is input to the 4: 3 monitor, the monitor side does nothing and outputs it as it is. On the other hand, when bit NO. 2 is “0”, that is, when the input video signal is a normal 4: 3 signal as shown in A of FIG. The side cut is displayed as shown in B or the display is enlarged vertically as shown in C of FIG. This vertically enlarged display creates invalid portions above and below C in FIG. 5, as indicated by the broken lines. When a normal 4: 3 input video signal is received by a 4: 3 monitor, it is output as it is. Further, as shown in A of FIG. 6, when an input video signal of 16: 9 is received by a monitor of 4: 3, B of FIG.
As shown in Fig. 6B, the letterbox is cut off at the top or bottom, or the monitor is used to the full as shown in Fig. 6C, but only the portions indicated by broken lines on both sides of the image are discarded.

Therefore, in this other embodiment, the recording device records the information corresponding to the aspect ratio of the input signal together with the still image information, and the reproducing device detects the information corresponding to the aspect ratio and determines the aspect ratio. Since the corresponding signal is inserted into the V blank and output to the monitor, the aspect ratio of the monitor can be automatically switched.

The video signal recording apparatus and / or reproducing apparatus according to the present invention is not limited to the above-mentioned embodiment, and for example, a so-called deep layer recording system in which the recording area is divided in the thickness direction of the magnetic tape is used. The present invention can be applied to a video tape recorder or the like which is adopted and can record an analog video signal and a digital signal in these areas, respectively. Further, the recording device and the reproducing device may be separate bodies.

[0041]

The video signal recording apparatus and / or reproducing apparatus according to the present invention records information according to the aspect ratio of a still picture input signal together with a still picture input signal, and detects information according to the aspect ratio. Since the signal indicating the aspect ratio is superimposed on the video signal of the still image and output, the aspect ratio of the monitor can be automatically switched. Further, by adding the same aspect ratio information to the soft tape, the usability is further improved. Further, if the ID of PCM is used as the insertion position of the aspect ratio information, the information will not be erased even when dubbing.
