Abstract

The invention provides a synchronization method and a synchronization system for scanning imaging, and the method comprises the steps: firstly carrying out the synchronous information analysis of an obtained video source, so as to obtain the synchronous information of the video source, which comprises line blanking and field blanking in the video source; and generating galvanometer driving synchronization information and light source driving synchronization information based on the synchronization information. The galvanometer driving synchronization information and the light source driving synchronization information are both based on the synchronization information of the video source, and synchronization between galvanometer movement and the light source driving synchronization information is achieved. The galvanometer driving synchronization information determines the motion state of the galvanometer, and the light source driving synchronization information determines the working state of the light source. The positions of the light source driving synchronization period and the motion period of the galvanometer are in one-to-one correspondence. Therefore, when driving control is carried out on the light source, the light source can start to display effective data in video data at a fixed position in the movement period of the galvanometer, and synchronization of galvanometer scanning and video data display of the light source is achieved.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a scanning imaging synchronization method and synchronization system. Background technique [0002] In the field of projection display technology, the main projection methods include: CRT (Cathode Ray Tube, CathodeRay Tube), DLP (Digital Light Processing, Digital Light Processing), LCD (Liquid Crystal Display, Liquid Crystal Display) and LCOS (Liquid Crystal on Silicon, Liquid Crystal Display) Crystal On Silicon), etc. [0003] In the above-mentioned projection methods, the video signals used, such as HDMI (High Definition Multimedia Interface), DVI (Digital Video Interface, Digital Visual Interface), DP interface (Display Port) and VGA (Video Graphics Array, Video Graphics Array), etc., all use the internal line blanking and field blanking signals as their synchronization reference. The video signal receiving or display device needs to locate and analyze th...
