Abstract

The utility model relates to an image trick photography lens, which comprises a person shoot imaging section and a scenery shoot imaging section, wherein, the person shoot imaging section is composed of a lens on the top of a lens body, a diaphragm and a photosensitive film of a reading lamp; an adjusting ring drives a rotating nail to enables a lens frame to move backwards and forwards, and thus to adjust a person focal length; the scenery shoot imaging section is composed of slides, a convex lens, a prism and a photosensitive film. A lens interface is connected with the port of the camera; the convex lens is arranged between the photosensitive film and a beam path of the slides; the slides is arranged on the side of the lens, and refracted to image by the convex lens and the prism via an outside light source. Local black picture on the slides corresponding to person's figure can be shot to image, and thus realizes single exposure imaging photography synthesis.

Description

The image cover is taken the photograph camera lens

The utility model is a kind of and the matching used bi-focal of photograph fuselage imaging simultaneously cover is taken the photograph camera lens, is specially; The image cover is taken the photograph camera lens.

Now Shen Qing image cover take the photograph camera lens comprise mirror group and lens respectively from different perspectives, different focal is imaged on portrait and lantern slide view on the same block of sensitive film after by prism transmission, refraction simultaneously.According to black not light sensitivity principles adopt the local view that has black, local black picture and the overlapping picked-up of portrait realize that image synthesizes.Existing Photographic synthesizer because image quality, effect are too poor, use and grasps not enough standard, and production is perfect inadequately, so this product can not be used widely and promote always.

The utility model can save original camera lens for providing a kind of, can improve the photographs process shot of image quality, effect again.

The utility model is to adopt following measure to realize; This image cover is taken the photograph camera lens and is connected in the camera mouth by lens interface, and the mirror group drives mirror holder with the picked-up personage that focuses by adjusting ring, rotation nail; Personage's image from the front by mirror group, aperture, through the imaging on sensitive film of prism perspective.The focal length of lantern slide view is fixed by convex lens, thereby the lantern slide view will be reflected in same sensitive film imaging by convex lens, prism from the side by external light source.Adopting the lantern slide view special, that the part is provided with black is entourage; Blackish part is corresponding with personage's image.Personage's background is a black, and black background and lantern slide figure, word, scape are corresponding.By black light sensitivity principles and take the bi-focal imaging not, people's scape image overlap cover is taken the photograph, thereby finished the image process cinematography of people's scape single exposure.

Image cover described in the utility model is taken the photograph camera lens, owing to use the prism refraction, take the bi-focal picked-up, also in conjunction with using not light sensitivity principles of black, make portrait and the shooting of the local black picture overlapping imaging of view nearby at a distance, thereby strengthened the image quality and the range of application of this process shot photography.

Accompanying drawing: the theory structure cut-away view of taking the photograph camera lens for this image cover.

Further retouch as follows to the utility model in conjunction with the accompanying drawings: after this image cover is taken the photograph camera lens and comprised lens interface (1) that lens body (10) is provided with above and the camera mouth is connected, by mirror group (2), sensitive film (11), constitute personage's imaging moiety.Adjusting ring (7) driven rotary nail (8), mirror holder (9) relatively rotate, to regulate personage's imaging focal length.Constitute view by lantern slide (6), convex lens (5), prism (4) and fit in the picture part: view makes sensitive film (11) imaging by external light source planoconvex lens (5) and prism (4) refraction.The picture of the local black of lantern slide (6) and personage's the corresponding imaging of image, it is synthetic to finish image.

Claims

1, a kind of image cover is taken the photograph camera lens, comprises from positive, side to image in sensitive film (11) simultaneously, comprises the built-in mirror group (2) of lens body (10), convex lens (5), the synthetic principle device of prism composition diagram pictures such as (4), it is characterized by:

---this image cover is taken the photograph camera lens, the mirror group (2) that comprises lens body (10) built-in location, top, sensitive film (11) in aperture (3) and the camera combine formation personage imaging optical path, adjusting ring (7), rotation nail (8), the relative motion of mirror holder (9) is to regulate personage's imaging focal length, the lantern slide (6) that also comprises the side location, convex lens (5) and sensitive film (11) are the light path refraction of the prism (4) at 90 ° of angles, constitute the view imaging optical path, also contain the lantern slide (6) that the part is provided with black and take the photograph combining of light path with personage's image overlap cover, it is synthetic to finish the photographs picture.

---supporting lantern slide (6) is local black; Its certain part is a black, and remainder is multicolour pattern, word or scape.
