Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for video-recording an image formed on an optical film using a mirror for changing the optical axis.

[0002]

2. Description of the Related Art A film photographing apparatus is generally used for photographing a positive film photographed with a still camera or the like, or for reversing a negative film into a positive photograph, and directly viewing it on a television screen.

Conventionally, this type of device is as shown in FIG.
The layout is linear, and the optical axis of the shooting lens is not bent to the film.

On the other hand, as shown in FIG. 5, the optical axis of the taking lens is bent at a right angle by a mirror so that the film can be taken. Film shooting devices have also been proposed.

In FIGS. 4 and 5, 1a and 1b are image pickup systems having a solid-state image pickup device and an image pickup circuit, 2a and 2b are photographing optical systems capable of changing the photographing magnification, and 3a is a mirror for bending an optical axis 4b at a right angle. 5a and 5b are opening windows of the film guides 6a and 6b. Film holders 7a and 7b hold the films 10a and 10b, and are movably guided in the insertion portions of the film guides 6a and 6b. 8a and 8b are light sources,
Opening windows 5a, 5 of the film guide are formed by the reflectors 9a 9b.
b. A close-up lens 11a is fixed to the exterior unit 12b together with the mirror 3a.

FIG. 6 shows a conventional example of FIG.
FIG. 2 is an external view of a film photographing device, showing a state of use in which a printed matter or the like is viewed on a television with the exterior unit 12b removed.

[0007]

However, as shown in FIG.
The film photographing device shown in Fig. 2 has a linear layout, and when photographing printed matter, three-dimensional objects, and landscapes in addition to film photographing, the imaging system and the photographing optical system are tilted with respect to the film guide. Since the lens itself had to be replaced or a conversion lens had to be attached, the operation was extremely troublesome and the work efficiency was low.

Further, in the film photographing apparatus shown in FIGS. 5 and 6, it is possible to take a picture other than the film by removing the close-up lens and the exterior unit holding the mirror. Since the lens is removed from the photographing optical system, the close-up photographing distance changes due to zooming of the photographing lens, and the photographing magnification is limited by the subject position. Furthermore, the optical axis is set to 90 by the mirror
Since it is bent, the entire device becomes smaller than the film photographic device with the linear layout shown in FIG. 4, but for this reason, a part of the device is used for wide-angle shooting when the close-up lens is removed. There was a problem that would enter the screen.

Further, as shown in FIG. 6, when an image of a printed matter is taken by removing the close-up lens and the mirror, since the movement of the printed matter in the vertical direction is restricted, the upper side of the printed matter can be enlarged. There wasn't.

[0010]

According to the present invention, an apparatus for videotaping a film is provided with a mirror for converting the optical axis, and the mirror is held so as to be rotatable about the optical axis. It is possible to provide a film photographing device having a wider photographing area than the above.

Further, by removing the close-up lens, it is possible to take a picture by rotating the mirror even when taking a picture of a landscape or the like. Then, the left-right inversion by the mirror is corrected by making the solid-state image pickup device have a mirror image output function, and the up-down inversion makes the image pickup system 180 °.
It can be corrected by rotating.

[0012]

1 and 2 and 3 show an embodiment of the present invention, FIG. 1 is an exploded perspective view, in which FIG. 1 shows an image pickup system including a solid-state image pickup device and an image pickup circuit, 2 Is an image pickup optical system, and the image pickup system 1 and the image pickup optical system 2 are held rotatably about an optical axis by a rotation holding mechanism (not shown). 3 is an optical axis conversion mirror that bends the optical axis 4 by 90 °. 5 is an opening window of the film guide 6. A film holder 7 holds the film 10 and is movably guided by the insertion portion of the film guide 6.

Reference numeral 8 denotes a light source, which irradiates the opening window 5 of the film guide with a reflecting plate 9. Reference numeral 11 denotes a close-up lens for close-up photography, which is detachably held by the exterior unit 12. 12 is a mirror 3 and a close-up lens 1
Exterior unit that holds 1. Reference numeral 12a is a flange portion for rotatably holding the exterior unit 12 on a main body unit (not shown). A detection switch 13 detects the rotation of the exterior unit.

In the above structure, as shown in FIG. 2, the exterior unit 12 is rotated 90 ° downward from the state shown in FIG.
The film 10 can be photographed by guiding the optical axis 4 to the opening window 5 of the film guide 6.

Next, as shown in FIG.
The printed matter 20 can be photographed by rotating it by 0 ° sideways.

As described above, since the exterior unit 12 can rotate with respect to the main body about the optical axis of the image pickup system side of the image pickup optical system, the film 10 as shown in FIG.
Can be taken, or the printed matter shown in FIG. 3 can be taken simply by rotating the exterior unit 12.

When the close-up lens 11 is removed from the exterior unit 12 and the exterior unit 12 is rotated to the position shown in FIG. 3, the optical axis is oriented in the direction parallel to the short side direction of the main body, so that even at the wide end. , The main unit does not enter the shooting screen.

The exterior unit 12 and the main body may be coupled to each other by using a ball race, a screw, a magnet or the like as long as they can be configured to be rotatable.

Further, a solid-state image pickup device having a mirror image output function is used as the solid-state image pickup device, a mirror image output switch is provided on the main body, and the exterior unit 12 shown in FIG. Can be prevented.
Further, the switch may be configured to be turned on automatically in association with the rotation of the exterior unit.

On the other hand, since the switch for turning off the power source of the light source 8 is interlocked with the rotation detecting switch of the exterior unit 12, when the angle of view of the photographic optical system is deviated from the opening window 5 of the film guide 6, the light source 8 is It is possible to turn off the lights and eliminate the adverse effects of the light source 8 on the subject other than the film (white balance and uneven brightness).

A gray code or a positioning sensor may be used for the rotation detection switch of the exterior unit 12 so that the switching timing can be changed depending on the rotation angle.

[0022]

As described above, since the mirror for converting the optical axis can be rotated about the optical axis of the photographing optical system, photographing other than film can be performed by a simple operation.

Further, the mirror makes it possible to provide a photographing region of 360 ° in a direction orthogonal to the optical axis without moving the image pickup system.

If the light source 8 is turned off in association with the rotation of the mirror, the adverse effect of the light source 8 on the subject other than the film can be eliminated.
