To provide spoke light compensation for motion artifact reduction.
An embodiment comprises color changers 14 and 16 that cause each of a set of primary colors to appear on an imager that illuminates a display screen with each of a plurality of pixels. Controllers 30 and 31 apply control signals to the imager to control the pixel brightness for each color. Each time the color changer transitions from one primary color to another, a spoke 18 occurs, and mixed light of two colors appears on the imager. The controller causes the imager to use such spoke light when the brightness level for each color for the associated pixel exceeds a prescribed threshold. When making use of the spoke light, the controller alters the control signal to decrease brightness of at least one primary color in substantial time proximate to the occurrence of the spoke to compensate for the brightness increase caused by using the light during the spoke.
