Abstract:
1. A projection apparatus comprising: a projection unit having an optical system that projects an image, a housing that houses the projection unit, an imaging unit that captures a projection surface on which the image is projected, and a projection region determining unit that determines a projection region on which the image can be projected by the projection unit, by use of a captured image of the projection surface captured by the imaging unit, wherein a surface of the housing that is used as a placement surface when setting the housing is parallel to the projection surface, and the projection unit performs an expansion and contraction process on an image projected on the projection surface while fixing in place one side closest to the housing within a region on which the projection unit can project the image on the projection surface, and projects the image onto the projection region, the expansion and contraction process being performed by processing an image signal.
