Abstract

The invention discloses a focusing method and device of a projector. The method comprises the steps that: the projector receives projection information sent from a terminal; the projector determines a first focusing parameter of a projection lens of the projector according to the projection information; and the projector controls the projection lens to focus according to the first focusing parameters. In the technical scheme, the projector determines the focusing parameter of the projector according to the projection information sent from the terminal and is not needed to measure each data for calculating the focusing parameter, the hardware investment of the projector is reduced, and the handling resource of the projector is saved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a projector focusing method and device. Background technique [0002] When a projector is used for image display, the projector is usually focused so that the image projected by the projector on a curtain or wall is clear and complete. Usually, the projector focuses according to the focus function of the built-in focus processor. If the focus function of the focus processor is damaged, focus cannot be achieved. Contents of the invention [0003] In order to overcome the problems existing in related technologies, embodiments of the present disclosure provide a focusing method and device for a projector. Described technical scheme is as follows: [0004] According to a first aspect of an embodiment of the present disclosure, a projector focusing method is provided, including: [0005] The projector receives the projection information sent by the terminal; [00...
