Abstract

See full text

An image projection apparatus displays includes a lens attachable portion to which a plurality of projection lenses having different optical characteristics are interchangeably attached, a drive signal producer configured to produce, for each color light beam, a drive signal used to drive the light modulation element based on an input image signal, and an information acquirer configured to acquire information on an optical characteristic of the projection lens attached to the lens attachable portion. The information on the optical characteristic of the projection lens contains information on a chromatic aberration of the projection lens. The drive signal producer reduces influence of a shift below the modulation pixel caused by the chromatic aberration of the projection lens by using the information on the optical characteristic, and produces the drive signal corresponding to at least one of the plurality of color light beams.
