Patent ID: 8408719

Claim:
A projection apparatus which projects images of respective color components sequentially by time division, the projection apparatus comprising: a light source section comprising k×n color light emitting elements such that n color light emitting elements are provided for each of k colors forming a color image (where n is a natural number greater than one, and k is a natural number greater than two); and a driving control section which drives the color light emitting elements to emit light simultaneously in at least two of the k colors, wherein one of the at least two colors is a main color, and the other at least one color is a supplementary color; wherein the driving control section drives each of the n light emitting elements of the supplementary color by a pulse width modulation scheme based on a phase difference of λ/(n·i) (where λ is a lighting period unit and i is a natural number greater than one), in synchronism with a projection period unit of the image of each color component.
