Abstract:
A projector is provided that includes a light source configured to radiate light, an electro-optical panel including a pixel circuit configured to receive light from the light source and emit the light, and an optical axis shifting element configured to shift an optical axis of the light emitted from the pixel circuit, with the projector being configured to display a pixel on a projection surface, based on the light emitted from the pixel circuit via the optical axis shifting element. When shifting a position of the pixel on the projection surface from a first position to a second position in a first direction, the optical axis shifting element shifts an optical axis of the light emitted from the pixel circuit using a path different from a shortest path from the first position to the second position.
