Abstract

The invention discloses a display control method and electronic equipment. The display control method is applied to the electronic equipment with a projection unit. The method includes processing an acquired first image corresponding to the first projection region, and determining a projection plane region from the projection region; acquiring at least one projection parameter used for adjusting the projection unit according to the projection plane region; adjusting the projection unit according to the at least one projection parameter, and allowing the projection unit to output projection images in the projection plane region.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a display control method and electronic equipment. Background technique [0002] Projection equipment can be connected with computers, VCD, DVD, BD, game consoles, DV, etc. through different interfaces to play corresponding video signals, and project images or videos onto the screen. In modern life and work, projection equipment is widely used in homes, offices, schools, and entertainment venues. According to different uses, the parameters of projection equipment are also different. [0003] In the prior art, including fixed-focus projection equipment and zoom projection equipment, fixed-focus projection equipment can only project a clear picture of a certain size at an installation distance. If you want to adjust the size of the projection picture, you must change the projector to the projection screen distance. Compared with the fixed-focus projection device, the zoom pro...
