Projector and method of projecting an image

A projector, comprising

• a first memory for providing an image as a matrix of pixels with intensities,
• a light source configured to emit a train of light pulses with variable intensities and intervals,
• a micro-electro-mechanical system, MEMS, mirror configured to oscillate about a horizontal axis with a horizontal oscillation period and about a vertical axis with a vertical oscillation period and to deflect the emitted light pulses onto a projection area,
• a second memory containing a playout matrix of a horizontal and a vertical duration for each pixel, and
• a processor connected to the first memory, the light source, the MEMS mirror, and the second memory,
• wherein the processor is configured to
• for a first half of every horizontal oscillation period, increment, and for a second half of every horizontal oscillation period, decrement a horizontal pixel index whenever one of the horizontal durations indexed by the current horizontal pixel index in the playout matrix has lapsed;
• for a first half of every vertical oscillation period, increment, and for a second half of every vertical oscillation period, decrement a vertical pixel index whenever one of the vertical durations indexed by the current vertical pixel index in the playout matrix has lapsed, and
• for each light pulse in the train:
• retrieve the respective intensity from the pixel matrix indexed by the current horizontal and vertical pixel indices,
• retrieve the respective horizontal and vertical durations from the playout matrix indexed by the current horizontal and vertical pixel indices,
• calculate an interval from at least one of said respective horizontal and vertical durations,
• emitting said light pulse via the light source with said retrieved intensity, and
• wait said calculated interval before emitting the next light pulse in the train.
