Abstract

The invention discloses a control method for controlling the focus of an imaging device. The imaging device includes a laser distance measuring device. The control method includes a determination step, a first control step, a processing step and a second control step. The determining step determines a subject of interest to the user. The first control step controls the laser ranging device to emit a laser pattern to the photographed area. The processing step processes the laser light of the returned laser pattern received by the laser distance measuring device to obtain motion information of the subject. The second control step controls the imaging device to continuously focus on the subject according to the motion information. In addition, the invention also discloses a control device and an electronic device. In the control method, control device and electronic device of the present invention, since a laser distance measuring device is adopted, a plurality of object distance values ​​of the photographed area including the photographed object can be obtained by emitting a laser image to the photographed area, It can also obtain the motion information of the subject, so as to continuously focus on the subject.

Description
