Abstract
The utility model discloses a kind of optical projection system exchanging project content, it is characterized in that, comprise the first projector, first projection screen, second projector, second projection screen and CCD camera assembly, wherein, first projector is connected to the first projection screen, second projector is connected to the second projection screen, second projector is connected to CCD camera assembly, and DSP process chip and FLASH storage medium is included in inside, project content on CCD camera assembly contrast shooting first projection screen, be stored in the FLASH storage medium in the second projector through analog to digital conversion and DSP process chip coded treatment, be shown on the second projection screen simultaneously.The utility model possesses exchange display, and sharing function at any time, solves projector functions single, can not share the problem of display.
Description
Technical field
The utility model relates to projector equipment, particularly a kind of optical projection system that conveniently can exchange project content.
Background technology
Along with projector is increasingly extensive in the application of industry-by-industry, user is to the practical application of projection, the convenience used and security also have more and more higher requirement, conventional projectors is generally by local USB flash disk, multimedias such as T-FlashCard or be connected with computer by VGA DVI line, like this content of multimedia inside computer is illustrated on large projection screen, each projector is independently, and the exchange of content is shared very inconvenient.
Utility model content
The purpose of this utility model is the deficiency for prior art, provides the optical projection system that conveniently can exchange project content.
To achieve these goals, the technical scheme that the utility model provides is:
A kind of optical projection system exchanging project content, comprise the first projector, first projection screen, second projector, second projection screen and CCD camera assembly, wherein, first projector is connected to the first projection screen, second projector is connected to the second projection screen, second projector is connected to CCD camera assembly, and DSP process chip and FLASH storage medium is included in inside, project content on CCD camera assembly contrast shooting first projection screen, be stored in the FLASH storage medium in the second projector through analog to digital conversion and DSP process chip coded treatment, be shown on the second projection screen simultaneously.
Comprise bluetooth module or WIFI module in described second projector, share transmission project content for wireless.
Described CCD camera assembly adopts sampling rate to be not less than the camera of 30 frames/second.
The beneficial effects of the utility model are, the utility model increases camera at projector, camera sampling is at more than 30fps, projector content is exchanged by bluetooth or WIFI transmission, solve projector functions single, can not share the problem of display, projector possesses exchange display, share at any time, enrich and expanded the interaction of projection products.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model embodiment exchanges the optical projection system of project content.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.
With reference to figure 1, the utility model embodiment provides a kind of optical projection system exchanging project content, comprise the first projector, first projection screen, second projector, second projection screen and CCD camera assembly, wherein, first projector is connected to the first projection screen, second projector is connected to the second projection screen, second projector is connected to CCD camera assembly, and DSP process chip and FLASH storage medium is included in inside, project content on CCD camera assembly contrast shooting first projection screen, be stored in the FLASH storage medium in the second projector through analog to digital conversion and DSP process chip coded treatment, be shown on the second projection screen simultaneously, bluetooth module or WIFI module is comprised in second projector, transmission project content is shared for wireless.
Described CCD camera assembly adopts sampling rate to be not less than the camera of 30 frames/second, cam lens generates optical imagery and projects in image sensor surface, then electric signal is transferred to, data image signal is become after A/D (analog to digital conversion) conversion, deliver to processing process in digital processing chip (DSP) again, because central controller CPU is connected with digital processing chip DSP, after central processor CPU editor, instruction exports the projector picture or music or video data that camera collection originally arrives.
From the above, the utility model increases camera at projector, camera sampling is at more than 30fps, projector content is exchanged by bluetooth or WIFI transmission, solve projector functions single, can not share the problem of display, projector possesses exchange display, share at any time, enrich and expanded the interaction of projection products.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
Claims (3)
1. one kind exchanges the optical projection system of project content, it is characterized in that, comprise the first projector, first projection screen, second projector, second projection screen and CCD camera assembly, wherein, first projector is connected to the first projection screen, second projector is connected to the second projection screen, second projector is connected to CCD camera assembly, and DSP process chip and FLASH storage medium is included in inside, project content on CCD camera assembly contrast shooting first projection screen, be stored in the FLASH storage medium in the second projector through analog to digital conversion and DSP process chip coded treatment, be shown on the second projection screen simultaneously.
2. the optical projection system exchanging project content as claimed in claim 1, is characterized in that, comprise bluetooth module or WIFI module in described second projector, share transmission project content for wireless.
3. the optical projection system exchanging project content as claimed in claim 1, is characterized in that, described CCD camera assembly adopts sampling rate to be not less than the camera of 30 frames/second.
