Abstract

The invention discloses a laser scanning imaging device. The laser scanning imaging device includes a readable storage medium, and the readable storage medium stores a program. The program includes control parameters for controlling the emitted light and stopping the emitted light of the laser scanning imaging device; When the adjacent first pixel and second pixel in the scanned image are scanned, the processor controls the laser scanning imaging device to first emit light of the color corresponding to the first pixel according to the control parameters, and then emit light corresponding to the second pixel at intervals of a preset time period. Colors of light. Since it is guaranteed that the gap between two pixel grids will be significantly larger than the gap between two pixel grids in the prior art, this greatly reduces or reduces the impact of each pixel grid on the previous pixel grid or the next pixel grid. The influence of the color and grayscale of the pixel grid improves the contrast and sharpness of the entire imaging picture, thereby improving the display quality of the imaging picture and ensuring the visual experience provided by the laser scanning imaging technology to users.

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] 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, the dashed box 101 is a virtual pixel grid, the pixel grid 101 and the pixel grid 102 are two adjacent pixel grids, the outgoing boundary 1012 of the pixel grid 101 and the incident boundary 1021 of the pixel grid 102 Coincidentally, the solid line circle 111 is the laser spot. It can be seen that when each pixel grid is scanned by the laser scanning imaging device, th...
