Abstract
The utility model relates to a projecting, photographing and shooting integrated device, which comprises a projecting optical path device and a photographing/shooting optical path device, wherein the projecting optical path device consists of a display chip, a prism and a projecting lens, and the photographing/shooting optical path device consists of an imaging chip and a photographing/shooting lens. The projecting, photographing and shooting integrated device is characterized in that the projecting lens and the photographing/shooting lens adopt an identical set of lenses, and a rotary reflector is arranged on the lower side of the rear of the lenses. When the rotary reflector is turned up, light which reflects from objects is focused by the lenses and reflects to the imaging chip by the aid of the reflector so that the imaging chip images by receiving external light, and the photographing/shooting lens is in use. When the reflector is turned down, the light from the display chip directly radiates to the prism and is reflected to an input end of the lens by the aid of the prism so that the display chip reflects or transmits light to image by the aid of the projecting lens, and the projecting lens is in use.
Description
Technical field
The utility model belongs to the optical system equipment technical field, relates to a kind of projection, photograph, video camera integrated device.
Background technology
Before the utility model 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.
The utility model content
The purpose of this utility model is 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 integrated device.
Be used to realize that the technical solution of foregoing invention purpose is such: the projection that is provided, take a picture, the video camera integrated device comprises one by display chip, prism, projecting light path's device that projection lens is formed and one are by imager chip, photograph/shooting light path device that photograph/pick-up lens is formed, it is characterized in that projection lens and photograph/pick-up lens adopt same set of optical lens camera lens, be provided with the rotating mirror that to dig or to fall along self minute surface basal edge at the rear of camera lens downside, 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 imaging, 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 of prismatic reflection to camera lens, this moment display chip reflection or transmitted ray by the projection lens imaging, product uses as projection lens.
Compared with prior art, the utility model is by to the organic combination in addition of projecting light path's device and photograph/light path of photography device in the digital camera/video camera product of traditional band projecting function, reduced small product size effectively, reduced cost, and make projecting light path can use high-quality photograph/phtographic lens on this basis, improved the projection definition greatly, keeping on digital camera/video camera original function basis, the significance level of projecting function on product also promoted greatly, so just properties of product have been improved in integral body, the practicality of projecting function is improved, can be used as the standard projection machine and use.
Description of drawings
Fig. 1 is the work structuring schematic diagram of a specific embodiment of the utility model.
Fig. 2 is the work structuring schematic diagram that the utility model is used as photograph/camera function pattern.
Fig. 3 is the work structuring schematic diagram that the utility model 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 the utility model content is described further, but concrete form of implementation of the present utility model is not limited in following embodiment.
Referring to accompanying drawing, projection described in the utility model, photograph, video camera integrated device are made up of members such as camera lens 1, rotating mirror 2, display chip (as DMD, LCD, LCOS etc.) 3, prism 4, imager chips (as CCD, CMOS etc.) 5.Wherein display chip 3, prism 4 and camera lens 1 constitute projecting light path, add a rotating mirror 2 in projecting light path, 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 utility model 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, display chip 3 and the prism 4 that constitute projecting light path this moment are not worked, camera lens 1 only uses as photographs/phtographic lens, imager chip 5 receiving systems outward light and imaging.
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 by the projection lens imaging.By as can be seen to the MTF curve chart 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. projection, take a picture, the video camera integrated device, comprise one by display chip (3), prism (4), projecting light path's device that projection lens is formed and one are by imager chip (5), photograph/shooting light path device that photograph/pick-up lens is formed, 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, after being converged by camera lens (1), the light of subject reflection reflexes on the imager chip (5) 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 of camera lens (1) again through prism (4).
