Abstract

The invention discloses a projection brightness adjustment method of an adaptive projection system. The system comprises a projector and a curtain. The curtain comprises a curtain body, a wireless transmitting module, a data handling module and a plurality of light sensation sensors evenly distributed on the curtain body; the projector comprises a control module, an angle adjustment module, a brightness adjustment module, a motor and a wireless receiving module. Before the projector starts working, the light sensation sensors at the center of the curtain body collect light brightness which is transmitted to the control module through the wireless transmitting module and the wireless receiving module after being processed by the data handling module, the control module obtains estimation projection brightness after adding a preset brightness difference on the received light brightness, and the estimation projection brightness is transmitted to the brightness adjustment module; the brightness adjustment module adjusts the brightness to the projection brightness of the projector according to the estimation projection brightness. The method is simple in structure, low in cost and capable of adjusting the projection brightness automatically.

Description

technical field [0001] The invention relates to the field of projection, in particular to a method for adjusting projection brightness of an adaptive projection system. Background technique [0002] Projectors, under the background of the country's policy of stimulating domestic demand and the continuous improvement of people's income, the implementation of the rural cultural sharing project has further promoted the rapid growth of China's projector market. According to statistics, in 2010 China's projector market shipments reached 1.28 million units, an increase of 43.6% compared to 2009. According to the analysis, China's projector market will continue to grow rapidly in 2011, with annual shipments reaching 1.67 million units and an annual growth rate of about 30%. In the next five years, the compound growth rate of China's projector market will reach 17.1%. [0003] China's projector product consumption market is mainly concentrated in large and medium-sized cities such...
