Summary of the invention
The utility model, in order to solve the problems of the technologies described above, provides a kind of projected picture merging device that can carry out large area projection and can project ultrahigh resolution image or video.
The utility model comprises projection screen, video image collecting unit and at least two projecting apparatus, video image collecting unit is connected with resolution lock unit, also be provided with and gather picture pixel displacement unit, blank level adjustment and Chromatically compensated unit and lock frame synchronization unit, gathering picture pixel displacement unit is connected with resolution lock unit, blank level adjustment and Chromatically compensated unit are connected with collection picture pixel displacement unit, lock frame synchronization unit is connected with blank level adjustment and Chromatically compensated unit, and projecting apparatus is connected with lock frame synchronization unit.
The beneficial effects of the utility model are, with the above projecting apparatus of two or two and corresponding resolution lock unit, gather picture pixel displacement unit and blank level adjustment, Chromatically compensated unit and lock frame synchronization unit and realize synchronous, the splicing of piecemeal video image and merge, projection goes out ultrahigh resolution, high brightness, large-area image or video; This projected picture merging device can be realized the multiple image model such as cambered surface, sphere, ladder and meet the multiple merging display modes such as Circamara, stereo sand table, spheroid image; Perfectly pure color merges Presentation Function.
The further feature of the utility model, by the description of following embodiment, is clearly recorded.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral explanation:
1. the first projecting apparatus, 2. the second projecting apparatus, 3. the 3rd projecting apparatus, 4. n projecting apparatus, 5. image/video, 6. projection screen.
Embodiment
As shown in Figure 1, the utility model comprises projection screen 6, the first projecting apparatus 1, the second projecting apparatus 2, the 3rd projecting apparatus 3, the first projecting apparatus 1, the second projecting apparatus 2 and the same projection screen 6 of the 3rd projecting apparatus 3 common use, the signal of projection is radiated on projection screen 6.
Video image collecting unit is for gathering the signal of image/video 5, the signal of image/video 5 can be VGA (notebook, desktop computer, graphics workstation), Video (video camera, DVD), DVI, SDI (broadcast level signal source), HD, HDMI and SDI.
Video image collecting unit is connected with the 1st resolution lock unit, the 2nd resolution lock unit and the 3rd resolution lock unit, and the 1st resolution lock unit and the 1st gathers picture pixel displacement unit, the 1st blank level adjustment and Chromatically compensated unit, the 1st lock frame synchronization unit is linked in sequence successively; The 2nd resolution lock unit and the 2nd gathers picture pixel displacement unit, the 2nd blank level adjustment and Chromatically compensated unit, the 2nd lock frame synchronization unit is linked in sequence successively; The 3rd resolution lock unit and the 3rd gathers picture pixel displacement unit, the 3rd blank level adjustment and Chromatically compensated unit, the 3rd lock frame synchronization unit is linked in sequence successively.
The 1st resolution lock unit is synchronously the video image signal of the first projecting apparatus 1 optimum physical resolution used for the signal that video image collecting unit is collected through digital processing, to guarantee the point-to-point demonstration of picture.
