JPH0444472A - Adaptor for still picture pickup - Google Patents

Abstract

PURPOSE:To make the profile of an adaptor for still picture pickup small by providing a lens cap removably to a position in front of an image pickup lens, an illuminant sheet member stored in the lens cap, a drive means for the illuminant member and a slit which is formed to a side wall of the lens cap to the adaptor. CONSTITUTION:When the adaptor 10 for still picture pickup is used, at first a negative film 14 is inserted to slits 28,28 of a lens cap 20 and the lens cap 20 is fitted to a video camera 12. When a battery 22 is applied, a voltage is applied to a light emitting element 26 via an inverter circuit 24 to light up the light emitting element 26. Thus, a light radiates a picture 14A of the negative filter 14 and the picture 14A is bright, the picture 14A is picked up by using the video camera 12. The lens cap is used as a frame for the adaptor for still picture pickup and the illuminant member or the like is stored in the lens cap, then the profile of the adaptor for still picture pickup is made small.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an adapter for taking still images, and more particularly to an adapter for taking still images used when taking images of negative film, film, etc. with a video camera. .

[Conventional technology]

When taking an image of a negative film with a video camera, the negative film set in a special adapter for taking negative film is illuminated with a fluorescent light, and the image is maintained at a uniform brightness before being taken with the video camera. This allows you to view the negative film image on a television screen.

[M problems that the invention attempts to solve]

As described above, since the dedicated adapter requires a fluorescent lamp that uniformly illuminates the negative film with white light, there is a problem that the dedicated adapter becomes large.

The present invention has been made in view of these circumstances, and it is an object of the present invention to provide a still image shooting adapter that can be made thinner and more portable.

[Means to solve problems]

In order to achieve the above object, the present invention provides a lens cap that is removable in front of a photographing lens of a video camera, a sheet-like light emitting member housed in the lens cap, and a drive for driving the light emitting member housed in the lens cap. and a slit portion formed in the side wall of the lens cap, into which a film is inserted and the film is positioned in front of the light emitting member.

[Effect]

According to the present invention, it is possible to downsize the light source by using a sheet-like light emitting member as a light source for irradiating the negative film, and therefore the light emitting member can be provided on the lens cap. Therefore, the lens cap can also be used as a still image shooting adapter for shooting images of negative film or the like. This allows the adapter for still image photography to be made thinner.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a still image shooting adapter according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a still image photographing adapter 10 of the present invention attached to a video camera 12. As shown in FIG.

The still image shooting adapter lO is attached to the front of the shooting lens (not shown) of the video camera 12.
0, a negative film 14 is placed parallel to the photographing lens.
is retained. This allows the video camera 12 to capture an image of the negative film 14. In this case, the video camera 12 is provided with a function of converting a manually produced image from a negative film 140 into the same image as an input image from a positive film.

In FIG. 1, 16 is a viewfinder, and 18 is a cassette storage compartment.

FIG. 2 is a sectional view of the still image shooting adapter 10. The still image shooting adapter 10 has a concave lens cap 20, and a button-shaped or sheet-shaped battery (lithium battery) 22 is provided at the bottom of the concave portion of the lens cap 200. The inverter circuit 2 comes into contact with this battery 22.
4 are provided. The inverter circuit 24 is the battery 2
2 and can perform DC/AC conversion.

The lens cap 20 is provided with an optical element 26 in contact with the inverter circuit 24.
and the optical element 26 are electrically connected. A sheet-like electroluminescent material is used for this optical element 26, and the surface of the electroluminescent material emits light when an alternating current electric field is applied.

Furthermore, slits 28.28 are formed in the side wall of the lens cap 20 to face each other, as shown in FIG. 3, and a brush 30 is provided in the slits 28.28. Therefore,
41st! The negative film 14 can be inserted into the slit 28.28 of the lens cap 20 as shown in FIG.

In addition, numeral 34 in FIG. 3 is a cover for attaching and detaching the battery 22.

When using the still image shooting adapter 10 configured in this way, first attach the negative film 14 to the lens cap 22.
into the slits 2g and 28, and the lens cap 20 is attached to the video camera 12 as shown in FIG. Next, when the battery 22 is powered on, a voltage is applied to the light emitting element 26 via the inverter circuit 24, and the light emitting element 26 emits light. Therefore, image 1 of negative film 14
4A is irradiated and the image 14A becomes blank, so that the video camera 12 can photograph the image 14A.

Although electroluminescence was used for the light emitting element 26 in the embodiment, the present invention is not limited to this, and other sheet-shaped light emitting elements may be used. Further, although a lithium neem battery is used as the battery 22, other batteries may be used as long as they are button-shaped or sheet-shaped.

In the above embodiments, the influence of negative film has been explained, but as long as it is a positive film, it can be used even with a video camera not provided with a negative/positive conversion function.

〔Effect of the invention〕

As described above, according to the still image shooting adapter according to the present invention, the lens cap can be used as a frame of the still image shooting adapter, and the light emitting member etc. can be stored in the lens cap. The image capturing adapter can be made thinner, that is, smaller in size. Therefore, portability can be improved.
