Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video signal recording apparatus, and more particularly, a video image of a negative film, a print or the like taken by a video camera and recorded on a recording medium such as a video tape or a magnetic disk. The present invention relates to a signal recording device.

[Background of the Invention]

Recently, with the spread of video cameras, video recording objects such as prints are recorded and stored on video tapes.
A so-called video television album has been utilized, which is played back by a playback device as necessary and is displayed on a television screen for enjoyment. In this case, since the object to be photographed is a piece of paper, such as a print, which requires a very troublesome operation for recording with a video camera, it is suitable for time-lapse photography with a video camera. A continuous photo mount has been proposed which can accurately position the relative position with the video camera at the time and is also useful for organizing and storing photographed objects such as prints.

Also, in the case of recording a photographic image of a long or continuous color or monochrome negative film of several frames on a video tape etc. one frame at a time like the above print, and playing back this on a reproducing machine and displaying it on a TV screen. There is.

By the way, in such a video signal recording device for photographic images,
In any case, in order to see these images, the display device (TV screen) is finally displayed as a television image.
, But the following problems occur. That is,
In the case of photographic images, frames shot vertically are mixed with frames shot horizontally, so for example, if you record this on a video tape, etc. with the frames shot horizontally positioned as a reference, it will be displayed on the TV screen. When projected, a photographic image taken vertically will have its image tilted 90 ° and will be projected horizontally. In addition, since the size of the TV screen is horizontally long, if the frame shot in the horizontal position is used as a reference and projected on the TV screen, the image of the frame shot in the vertical position lacks the upper and lower parts and is an important part of the photographic image. Is not displayed on the TV screen.

Therefore, as a video signal recording apparatus for solving such a problem, Japanese Patent Laid-Open No. 59-58976 and Japanese Utility Model Laid-Open No. 56-160058 are available.
There is one disclosed in the publication.

Each of the 114 includes a driving unit 116 controlled by the control unit 102.
And 118 respectively.

Although the support plate 63 is driven via the speed reduction mechanism, a sensor unit 120 for detecting the rotation end position of the rotation shaft 66 of the support plate 63 is installed in the motor box 28. The sensor unit 120 includes an angle signal generating plate 122 fixed to the rotating shaft 66.
A lamp 124 that generates an output signal when the signal plate 122 is in the horizontal position and its light receiving element 126, and a lamp 128 that generates an output signal when the signal plate 122 is in the vertical position and its light receiving element 1
Composed of 30 and.

In the present embodiment, only one vertical position is described, but the vertical position includes right-handed and left-handed vertical positions. A mark hole for discriminating the mark may be provided on the mount and the mark may be detected by the light receiving element, and the camera may be rotated (± 90 ° with respect to the lateral position).

The operation of the above configuration will be described with reference to the flowchart of FIG.

First, the prints of the same size are stored one by one in each of the storage sections 12 of the album 10. For the prints photographed in the vertical position, the mark hole 20 on the storage surface is provided, for example, at the tip of a ballpoint pen. The mark hole 20 is formed as shown in FIG. 1, and the mark hole 21 for recording time setting is extracted as needed. For example, the basic recording time is set to 5 seconds, and the mark hole 21 is formed when the recording time is longer than this. The mark hole 21 is not limited to one, but a plurality of marks can be provided. The album 10 with the print set is on the entrance side of the easel 30 (on the left side in Fig. 2).
It is placed in the state of being folded in a zigzag shape, and the top one sheet is inserted from the entry side of the sensor section 42, and the roller 38
Bite into.

After the above set, by turning on the power switch of each of the video camera 34, the control unit in the easel 30, the light 92, the VTR 98, and the monitor television 100, and pressing the start switch of the switch unit 96, the control unit 102 The motor 114 is rotated via the drive unit 118. This allows the drive roller 38
Is driven, and the album 10 inserted between the rollers is conveyed at a constant speed. When the transfer of the album 10 progresses and the mark hole 18 reaches right under the light source 46 as shown in FIG. 2, light reaches the light receiving element 52, and the control unit 102 causes the motor 114 to operate based on the stop signal generated by the light. Stop driving. The sensor unit 42 determines whether or not the mark hole 20 is opened at the same time when the mark hole 18 is detected, that is, whether the print is in the vertical position or in the horizontal position. When the mark hole 18 is detected, the vertical position is determined only when the light from the light source 48 is received by the light receiving element 54 at the same time, and the light receiving element 54 has no output signal while the light receiving element 52 has an output signal. In this case, it is determined that the photograph is a lateral position photograph. When it is determined to be the vertical position, the control unit 102 outputs a control command to the drive unit 116 to rotate the motor 72. When the motor 72 rotates, the video camera 34 and the support plate 63 are supported by the spherical bearing 59, so that they are smoothly rotated. When the rotation advances and the rotation shaft 66 rotates 90 °, the rotation signal generating plate 122 rotates together, and the signal plate 122 reaches the optical axis positions of the lamp 128 and the light receiving element 130. At this time, the light receiving element 130
The generated signal is applied to the input interface 104, and the control unit 102 causes the drive unit 116 to drive the motor based on this signal.
Send a stop command to stop 72. At the same time, the magnet 60 is energized to stop the rotary table 58 and absorb the vibrations of the support plate 63 and the like, and then the plungers 62 and 62 are actuated to insert the rod 62A into the V groove of the V block 61 and rotate the rotary table. 58 is definitely stopped. As a result, the video camera 34 is set at a position where the vertical print 26 can be photographed as an erect image. When it is determined that the next print is in the horizontal position after the video camera 34 has taken the vertical position photograph, the control unit 102 sends the drive unit 116 the instruction to rotate the motor 72 in the reverse direction. To do. This causes the motor 72 to rotate in the opposite direction, rotating the rotating shaft 66 in the opposite direction, and
122 also rotates in the opposite direction. When the video camera 34 is rotated to a position where the horizontal position photo can be taken as an erect image, the signal plate 126
Reaches the optical axis connecting the lamp 124 and the light receiving element 126. As a result, an output signal is generated from the light receiving element 126, and the control unit 102 stops the motor 72 based on this. at the same time,
The magnet 61 and the plungers 62, 62 are operated to surely stop the rotary table 58.

Further, regarding the horizontal position and the vertical position of the print, when the horizontal position is used as a reference, the upper and lower parts of the screen are cut off at the vertical position. Therefore,
The zoom ratio of the video camera 34 is changed so that almost all of the image recorded on the print is captured. Specifically, at the time of determining the vertical position of the print, the control unit 102 drives the zoom lens drive motor of the video camera 34 to rotate the potentiometer 88 to a predetermined rotation amount, and the zoom ring 82 to the set value on the wide angle side. When the vertical position is changed to the horizontal position, the zoom ring 82 is rotated to a predetermined set value to zoom up. That is, the print 24 in the horizontal position is projected almost entirely on the TV screen, and the print 26 in the vertical position is printed in the horizontal position.
Zoom in from the time of shooting so that the vertical edges of the vertical position fit within the short side of the TV screen.

When the positioning according to the print position of the video camera 34 is completed, an upright image of the print is displayed on the monitor television 100. Therefore, the operator confirms the focus, the angle of view, and the like while looking at the monitor image, and performs readjustment as necessary. After the confirmation of the image quality is completed, the operator presses the recording switch of the switch unit 96, so that the control unit 10
2 sets VTR98 to the recording state and starts recording. The recording time is the time set in the mark hole 21 according to the request of the client. When the set time ends, the control unit 102 puts the VTR 98 in a pause (PAUSE) state and then rotates the motor 114. The album 10 is conveyed by the rotation of the motor 114, and this conveyance is continued until the light receiving element 52 of the sensor unit 42 receives the light of the light source 46. After that, the above-described processing is repeated.

When the shooting of the print attached to the album 10 is completed, the end mark hole 22 of the mount 16 next to the final print is exposed. As a result, the light of the light source 50 passes through the end mark hole 22 and reaches the light receiving element 56, and an output signal is generated from the light receiving element 56. Based on this output signal, the control unit 102 determines that the print to be photographed is completed, and drives the motor 114 until the remaining part of the album 10 is paid out from the rollers 38 for conveyance.

In the above-described embodiment, since the load of the camera 34 is received by the bearing 59 and only the rotation is performed by the motor 72, there is an advantage that the load such as kinking and bending due to the start of the motor 72, the disturbance of the rotating shaft 66, etc. is reduced. There is. The bearing 59 is the gearbox 28.
It may be provided inside.

According to the above-described embodiment, since the rod 62A of the plunger 62 fits into the groove of the V block 61 when the rotary table 58 is stopped, vibrations in the rotation direction and the optical axis direction due to the camera rotation are eliminated.

In the above-described embodiment, since the camera 34 and the easel 30 are connected via the support plate 27, disturbance vibrations and overall vibrations are integrally shaken, and there is no adverse effect during photographing.

In the above embodiment, the magnet 60 and the plunger 62 are provided to stop the rotary table 58, but the magnet 60 can be omitted. Also, the turntable 58
The rotating table 58 is rotated by rotating the support plate 63. However, a gear may be formed on the outer circumference of the rotating table 58 to directly rotate the rotating table 58.

The photographic subject used in the present invention excludes a transmissive photographic subject such as a reversal film and a negative film, and includes a reflective photographic subject such as a print photograph. Further, although a magnetic tape is used as the recording medium in the above-mentioned embodiment, the recording medium is not limited to this, and a recording medium such as a magnetic disk or an optical disk can be used. In this case, for example, in the case where an image signal of one field or one frame is recorded on one track of concentric tracks on the disc and is reproduced repeatedly, it is not necessary to set the above-mentioned photographing time. . Further, in the above embodiment, the mark indicating the horizontal position or the vertical position formed on the strip-shaped object to be photographed is optically read, but the reading method is not limited to this, and is read electrically or mechanically. You may do it.

〔The invention's effect〕

As described above, according to the video signal recording apparatus of the present invention, the position mark indicating whether the object to be photographed arranged on each frame of the mount is the horizontal position or the vertical position is formed for each frame, and the transport unit is provided. When the frame is conveyed to the shooting position by the detecting means, the position mark of the frame is detected by the detecting means, and the detecting means detects the video at the position corresponding to the position of the object to be photographed arranged on the frame based on the position mark. Since the camera is rotated to the horizontal position or the vertical position about the optical axis of the photographing lens, it is possible to appropriately and automatically project the photographing target in which the horizontal position and the vertical position are mixed on the display screen.
