Projector apparatus using pulse-driven light sources of different colors

A control program for use with a projector apparatus comprising a light source configured to emit light beams of a plurality of color components, emissions of the light beams controlled individually, the control program comprising;

• first computer readable program means for forming images respectively corresponding to the color components using the light beams from the light source for each frame and sequentially projecting the images;
• second computer readable program means for driving the light source so that the light beams are emitted as light pulses having respectively predetermined pulse widths for a period in which each of the images are projected;
• third computer readable program means for detecting deterioration levels of the light source respectively for the color components;
• and
• forth computer readable program means for controlling the pulse widths of the light beams emitted from the light source based on the deterioration levels.
