Abstract
A laser projection apparatus includes a display control circuit, a laser source, a laser source driving circuit, and a light modulation device. The display control circuit includes an algorithm processor and a control processor. The algorithm processor is configured to: determine a gain value α of each frame of image according to a gray scale value of each frame of image, and transmit N current control signals, M enable signals, and image display data to the control processor. The control processor is configured to: transmit the N current control signals and the M enable signals to the laser source driving circuit; and transmit the image display data to the light modulation device. The light modulation device is configured to modulate beams emitted by the laser source according to the image display data to generate image beams.
