Abstract
The disclosed subject matter relates to a method of projecting an image by means of a light source emitting light pulses and an oscillating micro-electro-mechanical system (MEMS) mirror deflecting the emitted light pulses, comprising: providing a matrix of durations for each pixel, and incrementing or decrementing a pixel index whenever a respective duration indexed by the respective pixel indices in the playout matrix has lapsed; for each light pulse: retrieving the respective intensity and durations indexed by the current pixel indices, calculating an interval from at least one of said durations, emitting said light pulse with said retrieved intensity, and waiting said calculated interval before emitting the next light pulse. The disclosed subject matter further relates to a projector carrying out said method.
