Problems solved by technology

[0002] The existing contrast focusing is to drive the focusing lens to traverse multiple lens positions from the initial position to find the position with the highest image contrast to achieve focusing. Since the initial position may be far from the focusing position, the focusing lens moves a long distance during the focusing process. , affecting the focus speed

Abstract

The invention discloses a control method, and the method is used for controlling an imaging device. The imaging device comprises a focusing lens. The method comprises the following steps: analyzing the focusing position of the focusing lens of the imaging device during the former imaging, and obtaining the focusing experiential position; determining an experiential initial position according to the focusing experiential position; and driving the focusing lens to carry out the contrast focusing from the experiential initial position. According to the invention, a lens unit is moved to the experiential initial position before focusing, and the imaging device is controlled to start to carry out the contrast focusing of the focusing lens from the experiential initial position, thereby improving the focusing efficiency of a contrast focusing mode.

Description

technical field [0001] The invention relates to imaging technology, in particular to a control method, a control device and an electronic device of an imaging device. Background technique [0002] The existing contrast focusing is to drive the focusing lens to traverse multiple lens positions from the initial position to find the position with the highest image contrast to achieve focusing. Since the initial position may be far from the focusing position, the focusing lens moves a long distance during the focusing process. , affecting the focusing speed. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention provides a control method, a control device and an electronic device. [0004] The control method in the embodiment of the present invention is used to control the imaging device, the imaging device includes a focusing lens, and the control method includ...
