PROJECTION APPARATUS, PROJECTION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To suppress influence due to heat fluctuation of a light source, and to maintain quality of a projected image at high state.SOLUTION: A projection apparatus comprises: an LED array 17 which is a light source capable of emitting light by adjusting luminance of light emitting elements in a plurality of colors by every color; projection systems 13 to 16 and 18 to 21 which project color images of one frame by forming optical images by unit of field period by every color component by a color sequential system by using light from the LED array 17; and light source control systems 27 to 29, 25, and 22 to 24 which adjust brightness of the light emitting elements in each color of the LED array 17 on the basis of supply power waveform information for offsetting brightness fluctuation in each field period by every color component with respect to the LED array 17.
