Abstract

The invention discloses laser projection equipment and a display method of a projected image thereof, and belongs to the field of projection display. When the light source emits laser beams of other colors, the camera can perform image acquisition on the target object to obtain first image information. When the light source emits the laser beam of the target color, the camera can stop performing image acquisition on the target object and generate a shot image based on the first image information. As the camera does not collect the laser beam of the target color reflected by the projection screen, the problem of color cast of the finally generated shot image can be avoided. Or, when the light source emits the laser beam of the target color, the camera can collect the second image information and generate the shot image based on the first image information and the second image information. In addition, the second image information does not include the gray information of the target color, so that the problem of color cast of the finally generated shot image can be avoided.

Description

technical field [0001] The present disclosure relates to the field of projection display, in particular to a laser projection device and a method for displaying projected images thereof. Background technique [0002] With the gradual improvement of the functions of the laser projection device, the laser projection device can interact with the user through the social application after starting the social application (for example, a remote video application, a fitness application or a game application, etc.). [0003] In the related art, a laser projection device may include a host and a projection screen, and a camera is arranged on the projection screen. After starting the social application, the host can start the camera. The camera can photograph the user to obtain a photographed image, and send the photographed image to the host. The host can project the captured image onto the projection screen again, thereby realizing interaction with the user. [0004] When the envi...
