Abstract

The invention provides a light source adjusting system and a light source adjusting method. The light source adjusting system is used for detecting video source information through the brightness determining module, to obtain brightness level information of each frame of image of the video source information and video gain information corresponding to the brightness level information, enabling thelight source to determine the light source brightness when each frame of image of the video source information is displayed according to the light source brightness information corresponding to the light source level information. Therefore, the purpose of adjusting the brightness of the light source without intercepting light rays of the light source through the light engine is achieved, the problems of accelerated aging and shortened service life of the light engine caused by temperature rise of the light engine due to light intercepted in the light engine are avoided, and the light energy utilization rate of the light source is also improved.

Description

technical field [0001] The present application relates to the field of projection technology, and more specifically, to a light source adjustment system and a light source adjustment method. Background technique [0002] Projection equipment, also known as a projector or a projector, is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a video screen. It can be used for profile measurement with transmitted light, and can also be used to measure the surface shape of a non-through hole and observe the surface of a part with reflected light. [0003] Projection equipment mainly includes several parts such as light source, light engine, driver board and lens. Wherein, the driving board is used for receiving video content, and controlling the light engine based on the video content. The light engine expresses various colors by transmitting or reflecting light of different brightness to achieve the purpose of imaging. [...
