Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a shielding structure for a photographic image recording device, and in particular, the invention relates to a shield structure for a photographic image recording device, and in particular, a method for photographing prints, etc. with a video camera and recording them on a recording medium such as a video tape or a magnetic disk. The present invention relates to a shield structure for a photographic image recording device.

[Background of the idea]

Recently, with the spread of video cameras, so-called video cameras have become popular, allowing users to record prints and other objects on video tapes, store them, play them back on a playback device as needed, and enjoy watching them on a TV screen. TV albums are becoming more popular. In this case, the object to be photographed is a print that has been broken up one by one. Since recording with a video camera requires very troublesome operations, it is suitable for use in time-lapse video recording, and allows for accurate positioning relative to the video camera during recording, as well as for photographing objects such as prints. A continuous photo mount has been proposed that is useful for organizing and storing images.

In addition, photographic images on color or black and white negative or positive film may be recorded frame by frame on a videotape or the like in the same manner as the prints described above, and this may be played back by a playback device and displayed on a television screen for viewing.

By the way, in any case with such a photographic image recording device, in order to view these images,
Ultimately, the image will be displayed on a display device (television screen) as a television image, but the following problems arise. In other words, in the case of photographic images, frames shot in a vertical position and frames shot in a horizontal position coexist, so for example, if frames shot in a horizontal position are taken as a reference, frames shot in a vertical position are recorded on a videotape, etc. When recorded, a photographic image taken vertically will be tilted 90 degrees and displayed horizontally when displayed on a TV screen. To avoid such problems, if the video camera is in a vertical position, you must either rotate the video camera 90 degrees and take the picture, or leave the video camera as it is and rotate the frame 90 degrees. Furthermore, since the size of the TV screen is horizontal, if a frame shot vertically is displayed on the TV screen based on a frame shot horizontally, the top and bottom parts of the image will be cut off. There is a problem where important parts of the photo image are not displayed on the TV screen. This will be explained with reference to FIGS. 1A, B, and C. The dotted line indicates an effective display screen T when a video screen of a standard television signal is displayed on an image display device, and its vertical and horizontal dimensions are 3:4. In this example, the solid line indicates a frame P of a photographic image taken on a JIS135 type full-size film, and its length and width dimension ratio is 2:3.

In FIG. 1A, the horizontal width of the frame P in the horizontal position is substantially equal to the horizontal width of the effective display screen T, and its entire area is completely included in the effective display screen T.

Assuming that a vertically positioned frame P is photographed at the same magnification as in FIG. 1A, the diagonally shaded areas A above and below the frame P in the photographic image are missing, as shown in FIG. 1B. In this case, approximately 25% of the frames P of the photographic image are missing. In this case, about 1/4 of the image information carried by the photographic image is lost, and it is not preferable that a substantial part of the image information is lost. Therefore, the photographic magnification was lowered and the long side of the frame P of the photographic image in the vertical position was reduced to fit within the short side of the effective display screen T, as shown in FIG. 1C.

In FIG. 1C, the height of the vertically positioned frame P is substantially equal to the height of the effective display screen T, and its entire area is completely included in the effective display screen T. However, surfaces other than the photographic image P at the time of photographing are displayed in the shaded areas B on both sides of the effective display screen T, which is undesirable. Therefore, during photographing, shields are required on both sides of the vertically positioned frame. However, when a shielding object on a flat plate is displayed on a TV screen, a mere flat surface appears on both sides of the photographic image, which may impair the aesthetic appearance of the photographic image. If the body is used as a blindfold, the shadow of the shield will appear in the photographing area, which is undesirable.

[Purpose of invention]

The present invention was developed in view of these circumstances, and it allows for the proper display of photographic images in both horizontal and vertical positions on the display screen, and also allows for the reproduction of frames when photographing vertically positioned photographic images. The purpose of this invention is to propose a shielding structure for a photographic image recording device that shields both sides and makes the photographic image stand out on the display screen.

[Summary of the idea]

In order to achieve the above object, the present invention arranges photographic images in which images are recorded horizontally or vertically in a plurality of frames of a strip-shaped photographic object, and photographs these photographic images with a video camera to create a photographic image. In a photographic image recording device that records images on a recording medium, a pair of shielding bodies are arranged at the side edges of the photographing area of a vertical photographic image frame, and the shielding bodies have a curved surface. It is characterized by

Each of the supports 64 located on the side of the video camera 34 is equipped with lights 66 and 68 that illuminate the print located in the photographing area from an angle where reflected light does not enter the camera lens.

Further, the easel 30 is provided with a switch section 70 for starting recording and the like.
A video tape recorder (VTR) 72 is connected to the video camera 34 by a video and control cable, and a video signal obtained by photographing a print is recorded on a video tape.
A color monitor television 74 is connected to the VTR 72 and displays the content being photographed by the video camera 34.

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

First, one print of the same size is stored in each storage section 12 of the album 10, and if the print is photographed in a vertical position,
The mark hole 20 on the storage surface is extracted with a pointed object such as a ballpoint pen to form the mark hole 20 as shown in FIG. Album 10 with prints set is placed on the entry side of easel 30 (left side in Figure 3).
It is placed in a state where it is folded in a zigzag manner, and the topmost sheet of mount is inserted from the input side of the sensor section 42 and is caught by the rollers 38.

After the above settings, the video camera 34, the control section in the easel 30, the lights 66 and 68, and the VTR
72 and monitor television 74 are turned on, and the start switch of switch section 70 is pressed to rotate roller 38. As a result, the album 10 inserted between the rollers 38, 38 is conveyed at a constant speed. As the conveyance of the album 10 progresses and the mark hole 18 shown in FIG. 2 reaches just below the sensor section 42, the driving of the roller 38 is stopped based on a stop signal generated thereby. The sensor section 42 has a mark hole 18
At the same time as the detection of , it is determined whether the mark hole 20 has been made, that is, whether the print is in the vertical or horizontal position. If it is determined that the camera is in the vertical position, the video camera 34 is rotated by 90 degrees. As a result, the video camera 34 is set at a position where it can photograph the print 26 in the vertical position as an erect image.

Furthermore, in the horizontal and vertical print positions, when the horizontal position is used as a reference, in the vertical position, the top and bottom of the screen are cut off. Therefore, the magnification of the video camera 34 is changed so that almost the entire photographic image is captured. Specifically, when determining the vertical position of the print, the zoom lens drive motor of the video camera 34 is driven, the gear 62 is rotated to a predetermined rotation amount by the potentiometer 63, and the zoom ring 58 is rotated to the set value. to zoom down. Further, when changing from the vertical position to the horizontal position, the zoom ring 58 is rotated to a predetermined setting value to zoom up. That is, the print 24 in the horizontal position is projected on almost the entire surface of the TV screen T during playback, and the print 26 in the vertical position is zoomed down from the time when the print 24 in the horizontal position is taken, as shown in FIG. Make sure that the top and bottom edges of the vertical piece fit inside the short piece. As is clear from the television screen T in FIG. 5, when frames are photographed in a vertical position, the easel 30, guide piece 36, etc. are hidden by the shield 44, so the image displayed on the television image during playback is not unsightly. In addition, the shield 44
Since the surface of is formed as a circumferential surface, there will be no shadow caused by lighting on the print. Furthermore, since the shielding body 44 is formed in a semi-cylindrical shape, as shown in FIG.
Now, you will be able to observe the image of print 26 through the pillars on both sides, and it will be extremely satisfying from an aesthetic point of view.

In the embodiment described above, the shielding body is formed into a semi-cylindrical shape, but the shielding body 44 is not limited to this, and may have any other shape as long as the surface of the shielding body 44 is curved. That is, the surface of the shielding body 44 may have a convex paraboloid shape as shown in FIG. 6A, a concave paraboloid shape as shown in FIG. 6B, or It may have a concave circumferential surface shape as shown in FIG. 6C, or it may have a cylindrical shape as shown in FIG. 6D. Further, the surface shape of the shielding body 44 may be a curved surface as a whole;
As shown in the figure, uneven grooves may be formed on the surface. The uneven grooves shown in FIG. 7 can be applied to all the curved surface shapes shown in FIGS. 6A to 6D.

In the above embodiment, an album with prints pasted was used as an example of the object to be photographed.
Negative film or positive film can also be used as the object to be photographed. In this case, the video camera captures the photographic image transmitted from the light source, so in order to achieve the effect of a shield, this shield must be made of opal glass that has light diffusing properties and partially transmits light. It is preferably made of a translucent material such as , opal plastic or the like. Further, in the above embodiments, a magnetic tape is used as the recording medium, but the present invention is not limited to this, and other recording media such as magnetic disks and optical disks can be used.

[Effect of idea]

As explained above, according to the shielding structure of the photographic image recording device according to the present invention, since the shielding bodies are arranged at both edges of the photographing area, when a vertical photographic image is reproduced, the guide pieces etc. included in the photographing area are You can blindfold yourself so that it doesn't appear on the TV screen. In addition, since the shielding body surface is formed into a curved shape, there will be no shadows caused by riding in the shooting area.
In addition, the image projected on the TV screen is similar to viewing a photographic image through a pillar, making it stand out from the photographic image and making it extremely aesthetically pleasing.
