Patent ID: 7287866

Claim:
An image projection apparatus, comprising: a light modulation system; a projection optical system for projecting a two-dimensional image onto a surface to be projected with light from the light modulation system; image signal processing means for supplying an image signal to the light modulation system; a power supplying portion for supplying power to the light modulation system; a head portion that contains the projection optical system; a main body portion that contains the power supplying portion; and a drive connection portion for connecting the head portion with the main body portion, in which the head portion and the main body portion can be relatively rotationally driven about a rotational axis which is not in parallel with an optical axis of the projection optical system, wherein a position onto which the light from the light modulation system is projected is changed by varying a relative angle in the rotational direction about the rotational axis between the head portion and the main body.
