1. A non-transitory computer-readable-medium storing instructions that, when executed by a processor of an image projector, cause the image projector to perform operations comprising:
receiving a first image data;
determining a thermal state of the image projector based at least in part on a content of the first image data;
adjusting the first image data based on the thermal state, thereby generating a second image data;
emitting light in response to the second image data; and
projecting an image onto a screen based on the emitted light, wherein the first image data corresponds to a frame of a video, and the second image data corresponds to the frame of the video,
wherein the emitting light in response to the second image data includes generating a raw illumination beam in response to the first image data, and adjusting the raw illumination beam based on the second image data.
