Abstract

The invention discloses an information processing method and electronic equipment. The information processing method comprises that a first range finding unit of the electronic equipment obtains a first projection distance between a projection head and a first projection surface; a first focusing stroke corresponding to the first projection distance is obtained based on the first projection distance and the correspondence between the focusing distance and the focusing stroke; and on the basis of the first focusing stroke, the focusing device of the projection unit is automatically adjusted to a first position, so that a projection image which is projected by the projection unit onto the first projection surface is clear. According to the technical scheme provided by the invention, the technical problem that in the prior art, the electronic equipment cannot realize manual focusing based on user operation without projection images is solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] With the continuous development of science and technology, various electronic devices are also emerging, and the combined application of electronic devices has brought great convenience to people's life and work. Among them, the configuration of built-in projectors in electronic devices has become A development trend. [0003] In actual life, when users need to obtain good visual effects while watching videos or pictures, they need to project the videos or pictures in the mobile phone onto a large projection screen for viewing; The PPT on the notebook is projected to the big screen for playback. During projection, in order to make the projected projection picture clear, the user needs to manually adjust the focus. [0004] In the process of inventing the technical solutions in the embo...
