Title:
PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/021850
Kind Code:
A1
Abstract:
Provided are: a projection device that is able to maintain electric connection to a movable part even when rotation of the movable part is repeated and that is able to detect, without adding a dedicated sensor, the rotation position of the movable part and is able to adjust a projection image in accordance with the projection direction; a method for controlling the same; and a program. A second member 3 rotatably supported by a body part 1 and a first member 2 includes a reflection member 32, movable-part-side contact points N1, N2, a drive unit 35 electrically connected to the movable-part-side contact points N1, N2, and an optical member 33a driven by the drive unit 35. The body part 1 is provided with a system control unit 14 that detects the rotation position of the second member 3 on the basis of the positions of fixed-part-side contact points E1-E4, of the first member 2, being in contact with the movable-part-side contact points N1, N2, that controls the drive unit 35 by applying electric current to the fixed-part-side contact points E1-E4 in contact with the movable-part-side contact points N1, N2, and that, on the basis of the rotation position of the second member 3, changes the orientation of image data to be inputted to an optical modulation element drive unit 12b.
