Embodiment Construction

[0015] see figure 1 and figure 2 , figure 1 It is a schematic diagram of the projector 10 projecting to a display screen 11 according to the present invention, figure 2 is a functional block diagram of the projector 10 . The projector 10 includes a casing, an imaging module 14 , a detection module 15 , a processor 20 and a display device 22 . The detection module 15 includes a signal transmitter 16 , a signal receiver 18 , a judgment module 25 , and a clock 24 . The clock 24 is connected to the judging module 25, and the judging module 25 detects the time when the signal transmitter 16 transmits the detection signal and the time when the signal receiver 18 receives the detection signal according to the time of the clock 24, so as to judge the directions from the projector 10 to the projector 10 distance. The imaging module 14 includes a light source power supply 26 and a light source 28, and the imaging module 14 is used to project images to the display screen 11 in fro...

Abstract

The projector includes one casing, one imaging module, one detection module and one processor. The imaging module projects image to the display screen in front of the projector; the detection module detects the distance between the projector and the front of the projector and the distance between the projector and the back of the projector; the processor regulates the brightness of the image the imaging module projects based on the distance between the projector and the front of the projector and the distance between the projector and the back of the projector.

Description

technical field [0001] The invention relates to a projector, in particular to a projector capable of adjusting the screen size and brightness according to the size of the environment. Background technique [0002] In general meeting briefings and other occasions, in order to allow participants to clearly understand the discussion content, the moderator can project report-related content or charts on the display screen by operating the projector, so that participants can watch the projection on the display screen clearly grasp the content of the report. However, with the advancement of audio-visual equipment and storage media, the scope of use of projectors, such as high-power speakers, high-storage DVDs, etc., makes it possible for ordinary families to use projectors with speakers at home, and projected images through projectors. The super-large screen enjoys the immersive audio-visual experience just like in a movie theater. This makes the scope of use of projectors gradu...
