Abstract

A projection apparatus, an illumination apparatus thereof, and a light source driving method thereof are provided. A control module converts a bit control signal into first light source timing signals, converts the first light source timing signals into second light source timing signals according to a lookup table, generates a driving current corresponding to each light source according to the lookup table, outputs second light source driving signals corresponding to the light sources according to the second light source timing signals. The lookup table includes a driving current ratio corresponding to the light sources. A driving module drives the light sources according to the second light source driving signals and the driving current for the light sources to have overlapping light-emitting timings.
