Abstract

PURPOSE:To project properly a photographic picture and to prevent a damage to a film by placing a carrying section of a strip film onto a turntable and driving the turntable based on a command signal whether each frame of the film is placed laterally or longitudinally. CONSTITUTION:A film carrier 20 having the supply section 22 and the reception section 24 of the film is placed on the turntable 26. A video camera 32 is picked up by a carrying film transmitted and irradiated from downward. A film detection sensor existing on the upper part of the carrier 20 reads a notch of the film so as to detect the kind of the film and whether the frame of film is placed laterally or longitudinally. When the sensor 40 decides it as longitudinal pickup, a signal is transmitted from a controller 44 to a drive motor 94 to drive the turntable 26. Thus, the carrier 20 is driven together with the turntable 26 to rotate the frame of the film by 90 deg.. When it is decided as lateral position pickup, the motor 94 uses the said control signal and restores the table 26 to the original position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a video signal recording device for photographic images, and more particularly, to a video signal recording device for photographic images, and in particular, to record a negative film or the like with a video camera and record it on a magnetic disk.
The present invention relates to a video signal recording device for photographic images recorded on a recording medium such as a videotape.

[Background of the invention]

Recently, with the spread of video cameras, photographic images of long lengths or consecutive frames of color or black and white negative film are recorded frame by frame on magnetic disks, video tapes, etc., and these are played back on a playback device and then displayed on a TV. It may be displayed on a screen for viewing.

By the way, in such a video signal recording device for photographic images,
In either case, in order to view these images, they are ultimately displayed on a display device (TV screen) as television images.
However, the following problems occur. That is,
In the case of photographic images, frames shot vertically and frames shot horizontally coexist, so for example, if you record frames as they are on a magnetic disk, videotape, etc. based on frames shot horizontally, When displayed on a television screen, a photographic image taken vertically will be tilted 90 degrees and displayed horizontally. In order to avoid such a problem, if the video camera is in a vertical position, the video camera must be rotated 90 degrees to take a picture, or the video camera must be left as it is and the frames must be rotated 90 degrees to take the picture. However, in the former case, a drive mechanism for rotating the video camera is required, but the drive mechanism may become complicated in order to rotate the video camera with high precision without misaligning the optical axis. Furthermore, in the latter case, since the film or the like that is the object to be photographed is twisted, there is a risk that cuts, creases, etc. may occur in the film, and the film may be damaged. In particular, when shooting in a vertical position, regardless of the type of camera, the images taken by the photographer may be upside down relative to each other, and even when shooting in a horizontal position, Depending on the type of camera, the top and bottom of the images taken may be relatively opposite to each other. Therefore, if you want to correct the photographed object to an erect image in all of these cases, the photographed object must be viewed over at least 270 degrees. Since it is necessary to rotate the film, the risk of damage to the film and the like described above becomes extremely large.

The pinion 92 is rotationally driven by a motor 94. Furthermore, sensors 41 and 42 are arranged on the outer circumferential side of the rotary table 26, separated by 90 degrees. Position sensor 41.42
is constituted by a transmission type sensor, and when a sensor blade 98 protruding from the outer periphery of the rotary table 26 is located, it issues a signal to stop the rotary table 26.

The operation of the embodiment of the present invention constructed as described above is as follows.

First, film 10 is unwound from supply reel 66 by take-up reel 68, which is driven by film drive rollers 72, 72 and reel drive roller 88. Light #28
The light emitted from the rotary table 26 passes through the opening 89 of the rotary table 26, and then passes through the opening of the film carrier 20 to the film 10.
The video signal is recorded on the magnetic disk 38 via the video camera 32 and video circuit 34 as described above. At this time, if the film detection sensor 40 is determined to be in the vertical position by the notches 16.18 formed on the side edges of the film 10, a signal is sent from the control device 44 to the drive motor 94, and the drive motor 94 is It operates to rotate the rotary table 26 via the pinion 92. Since the rotary table 26 rotates and the film carrier 20 is placed on the rotary table 26, both the supply section 22 and the receiving section 24 rotate together with the rotary table 26, thereby rotating the frame of the film 10 by 90 degrees. As a result, the video signal recorded on the magnetic disk 38 is that of an erect image. Further, when the film detection sensor 40 determines that the photograph is taken in a horizontal position, the motor 94 is reversely rotated by a control signal from the control section 44, and the rotary table 26 is returned to its original position. Regarding such directional movement of the film 10, since the film carrier 20 as a whole rotates together with the rotary table 26, the film 1o is not twisted, and therefore, no damage such as cutting or folding of the film 1o occurs.

In the embodiment described above, the rotary table 26 was rotated by 90 degrees, but the present invention is not limited to this.

For example, when shooting in a vertical position, regardless of the type of camera, the images taken may be upside down relative to each other due to the habits of the photographer; Depending on the type, the top and bottom of the captured images may be relatively reversed. Therefore, in order to correct the object to be photographed into an erect image in all of these cases, it is necessary to rotate the object to be photographed by at least 270 degrees. Bye.

In this case, the photographic mount is usually formed in a meandering manner, so that reels are not required in the supply and receiving sections, but other storage structures are required.

In the above embodiment, the notch formed on the edge of the film was read optically, but the reading method is not limited to this, and it may be read electrically or mechanically. Further, the signal supporting the horizontal or vertical position does not necessarily have to be detected from a mark formed on the object to be photographed; for example, it may be obtained from another medium (punch tape) or the like.Furthermore, the supporting signal may be detected visually. [Effects of the Invention] As explained above, according to the video signal recording device for photographic images according to the present invention, the conveying section including the supplying section and the receiving section of the object to be photographed can be used for vertical shooting or horizontal shooting. It rotates as a whole depending on the shooting position, and it is possible to shoot horizontally or vertically without twisting the object, so there is no chance of cutting or bending the object, which would damage the object. There isn't.
