<p><P>PROBLEM TO BE SOLVED: To suppress an influence by heat fluctuation of a light source, and to maintain quality of a projected image at high state. <P>SOLUTION: This projection apparatus includes: an LED array 17 which is the light source capable of emitting light by adjusting luminance of light emitting elements in a plurality of colors by every color; projection systems 13-16, 18-21 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 using light from the LED array 17; and light source control systems 27-29, 25, 22-24 which adjust brightness of the light emitting elements in each color of the LED array 17 based on supply power waveform information for offsetting brightness fluctuation in each field period by every color component to the LED array 17. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
