Abstract

The invention discloses a laser scanning imaging device, which includes a processor and a laser scanning imaging device. The laser scanning imaging device includes a light source and a scanner. The light emitted by the light source is composed of light of different colors emitted by three lasers. The laser is in one-to-one correspondence with the three color channels of each pixel in the image to be scanned; in the process of scanning two adjacent pixels in the image to be scanned, when two adjacent pixels have at least one color channel with the same value , the processor controls the lasers corresponding to the color channels with the same value to continuously emit light. Through the invention, the modulation frequency of the circuit and the laser is reduced, the reliability of the whole laser scanning imaging equipment is improved, and the service life of the laser scanning imaging equipment is increased.

Description

technical field [0001] The invention relates to the field of laser scanning projection, in particular to a laser scanning imaging device. Background technique [0002] Laser scanning imaging refers to the use of laser light as a light source, scanning on the image plane with a laser scanning imaging device according to a preset method, and at the same time changing the color of the emitted laser light, so that laser scanning imaging can be realized on the image plane. [0003] Currently, in the process of realizing laser scanning imaging, please refer to figure 1 , figure 1 It is a schematic diagram of laser scanning imaging in the prior art, such as figure 1 As shown, when the scanning point corresponding to the laser scanning imaging device enters the pixel area 101, it starts to control the laser in the light source to emit light of the corresponding color. The light emitted by the light source forms a spot 111 on the image surface, and the scanning point leaves the pix...
