Abstract
A method, a system, and a computer program product for reducing heat generated during projection of visual content. The method includes determining a temperature of at least one light emitter that projects a visual content based on calibration data. The method further includes determining, by a processor, whether the temperature exceeds a temperature threshold. The method further includes calculating, by the processor, at least one adjustment that reduces a level of heat generated by the at least one light emitter during projection of the visual content. The at least one adjustment overrides at least one portion of the calibration data. The method further includes applying the at least one adjustment to the at least one light emitter and modulating the at least one light emitter to project the visual content in accordance with the at least one adjustment applied to the calibration data.
