The system which adjusts the optical output of method and the projection system which adjust the optical output of the projection system

摘要

Disclosed is a method for adjusting light output of a projector that includes compiling a switching sequence having long and short segments for the controllable elements of a display unit, a long segment being of a duration greater than or equal to a threshold and a short segment being of a duration less than the threshold; obtaining a light output adjustment measure by which the light output is to be adjusted; generating a light pulse sequence such that the duration of a light pulse corresponds to the light output adjustment measure; and arranging the light pulse relative to the switching sequence such that the activation of the light pulse does not occur during a short segment, wherein the predefined threshold is a time duration of the light pulse at a lowest dimming level such that the light pulse has settled by the time the long segment ends.
