Abstract
A projection system 1 includes a projector 3_1 that updates an image Img_1 by vertical scanning of an internal liquid crystal panel and shifts a projection position of the image Img_1, and a projector 3_2 that updates an image Img_2 by vertical scanning of an internal liquid crystal panel and shifts a projection position of the image Img_2. When there is an overlapping region in which the image Img_1 projected by the projector 3_1 and the image Img_2 projected by the projector 3_2 overlap each other along a direction parallel to a direction of the vertical scanning direction, the vertical scanning direction of the liquid crystal panel of the projector 3_1 and the vertical scanning direction of the liquid crystal panel of the projector 3_2 are set to be opposite to each other.
Claims4
A projection system comprising:
- a first projector including
- a first electro-optical device configured to emit first image light representing a first screen updated by vertical scanning,
- a first optical path shifting element configured to shift an emission optical path of the first image light, and
- a first projection optical member configured to project the first image light having the emission optical path shifted;
- a second projector including
- a second electro-optical device configured to emit second image light representing a second screen updated by vertical scanning,
- a second optical path shifting element configured to shift an emission optical path of the second image light, and
- a second projection optical member configured to project the second image light having the emission optical path shifted;
- and
- a vertical scanning direction setting unit, wherein
- when there is a first overlapping region in which the first image light projected by the first projection optical member and the second image light projected by the second projection optical member overlap each other along a first direction parallel to a direction of the vertical scanning, the vertical scanning direction setting unit sets a direction of the vertical scanning in the first electro-optical device and a direction of the vertical scanning in the second electro-optical device to be opposite to each other.
