Abstract
The invention relates to a projection, camera and video camera integrated structure. The integrated structure comprises a projection light path structure including a display chip, a prism and a projection lens, and a camera/video camera light path structure including an imaging chip and a camera/video camera lens. The integrated structure is characterized in that the projection lens and the camera/video camera lens use the same optical lens shot. A rotating mirror is disposed on a lower side at the rear of the shot. When the rotating mirror is turned up, light rays reflected by an object being imaged pass through the rotating mirror after being converged by the shot, and is reflected on the imaging chip which receives the light rays outside a system and forms images. A product herein is used as the camera/video camera lens. When the rotating mirror is laid down, the outgoing light rays from the display chip directly enter the prism and is reflected to an input end of the shot by the prism, and the imaging chip reflects or transmits the light rays to form images through the projection lens. The product herein is used as a projection lens.
Description
Technical field
The invention belongs to the optical system equipment technical field, relate to a kind of projection, photograph, video camera integral structure.
Background technology
Before the present invention's technology proposes; Digital camera/the video camera of existing band projecting function; Its photograph/camera system and optical projection system structurally are separate; They only carry out interactive communication on electronic information, promptly the electronic signal transmission of photograph/shooting information gives optical projection system as information source.In the framework of prior art, optical projection system only is provided with as an additional function, in order to reduce to take a picture/volume of video camera; Particularly the volume of camera lens just must be minimum for the volume of optical projection system; The eyeglass number also seldom so that the mtf value of projection lens is relatively poor, the resolution under high spatial frequency descends and is exceedingly fast; Finally cause the image quality of product lower, practicality is not strong.
Summary of the invention
The objective of the invention is to the problem that prior art exists is solved; Provide a kind of and make that independently optical projection system and photograph/camera system are combined closely; Thereby significantly improve entire system imaging level, effectively reduce small product size and the projection that reduces cost, photograph, video camera integral structure.
Be used to realize that the technical solution of foregoing invention purpose is such: the projection that is provided, photograph, video camera integral structure comprise a projecting light path's structure and the photograph of being made up of imager chip, the photograph/pick-up lens/shooting light channel structure be made up of display chip, prism, projection lens; It is characterized in that projection lens and photograph/pick-up lens adopt same set of optical lens camera lens; Downside is provided with the rotating mirror that can dig or fall along self minute surface basal edge at the rear of camera lens; After rotating mirror is dug; After converging by camera lens from the light of subject reflection through the rotation mirror reflects to imager chip; The outer light of imager chip receiving system this moment and forming images, product uses as photograph/pick-up lens; After rotating mirror falls, be directed to prism by the light of display chip outgoing, again through the input end of prismatic reflection to camera lens, this moment display chip reflection or transmitted ray through the projection lens imaging, product uses as projection lens.
Compared with prior art, the present invention has reduced small product size effectively through to the organic combination in addition of projecting light path's structure and photograph/light path of photography structure in the digital camera/video camera product of traditional band projecting function; Reduced cost; And make projecting light path can use high-quality photograph/phtographic lens on this basis, and improved the projection sharpness greatly, keeping on digital camera/video camera original function basis; The significance level of projecting function on product also promoted greatly; So just improved properties of product, the practicality of projecting function is improved, can be used as the standard projection machine and use in integral body.

Fig. 1 is the work structuring synoptic diagram of a specific embodiment of the present invention.
Fig. 2 is the work structuring synoptic diagram that the present invention is used as photograph/camera function pattern.
Fig. 3 is the work structuring synoptic diagram that the present invention is used as the projecting function pattern.
Each label is represented respectively in the accompanying drawing: 1--camera lens, 2-rotating mirror, 3-display chip, 4-prism, 5-imager chip.
Embodiment
Below in conjunction with accompanying drawing content of the present invention is further specified, but practical implementation form of the present invention is not limited in following embodiment.
Referring to accompanying drawing, projection of the present invention, photograph, video camera integral structure are made up of members such as camera lens 1, rotating mirror 2, display chip (like DMD, LCD, LCOS etc.) 3, prism 4, imager chips (like CCD, CMOS etc.) 5.Wherein display chip 3, prism 4 and camera lens 1 constitute projecting light path, in projecting light path, add a rotating mirror 2, and rotating mirror 2 is located at the place ahead downside of camera lens 1 and can digs or fall along self minute surface basal edge.After rotating mirror 2 is dug, promptly constituted photograph/light path of photography by imager chip 5, rotating mirror 2 and camera lens 1, so just integrated projection, photograph/shooting light path effectively, make it be able to a shared high-quality camera lens.
Real work pattern of the present invention is divided into two kinds of photograph/camera function pattern (as shown in Figure 2) and projecting function patterns (as shown in Figure 3).
1, photograph/camera function pattern:
Referring to Fig. 2, under this pattern, rotating mirror 2 is shown in an open position, the display chip 3 that constitutes projecting light path this moment is not worked with prism 4, and camera lens 1 only uses as photographs/phtographic lens, the light outside imager chip 5 receiving systems and forming images.
2, projecting function pattern:
Referring to Fig. 3; Under this pattern, make rotating mirror 2 in the closed position, constitute imager chip 5, the rotating mirror 2 of photograph/light path of photography this moment and do not work; Camera lens 1 only uses as projection lens, and display chip 3 reflections or transmitted ray are through the projection lens imaging.Through finding out to the MTF curve map of projection lens under this structure, outstanding equally because of projecting light path has adopted high-quality (mtf value is outstanding) camera lens to the analytic ability of high spatial frequency, can guarantee good imaging definition.
Claims (1)
1. a projection, photograph, video camera integral structure; Comprise a projecting light path's structure and the photograph of forming by imager chip (5), a photograph/pick-up lens/shooting light channel structure of forming by display chip (3), prism (4), projection lens; It is characterized in that: projection lens and photograph/pick-up lens adopt same set of optical lens camera lens (1); Be provided with the rotating mirror (2) that to dig or to fall along self minute surface basal edge at the rear downside of camera lens (1); After rotating mirror (2) is dug,, the light of subject reflection reflexes on the imager chip (5) after being converged by camera lens (1) through rotating mirror (2); After rotating mirror (2) falls, be directed to prism (4) by the light of display chip (3) outgoing, reflex to the input end of camera lens (1) again through prism (4).
