Method, system and equipment for solving foreign matter at motor bottom of camera module

Abstract

The application discloses a method, system and equipment for solving foreign matter at motor bottom of a camera module. The method comprises the following steps: acquiring parameter data when the motor of the camera module is started to obtain target data; judging whether the target data is greater than preset parameter data; if the target data is greater than the preset parameter data, judging that the foreign matter is existent at the motor bottom; increasing the starting current of the motor through a driver of the camera module to solve the problem that the foreign matter is existent at the motor bottom. Visibly, the driving current of the motor is regulated through the driver of the camera module through the method for solving foreign matter at the motor bottom of the camera module provided by the invention, specifically, the starting current for driving the motor is increased, so that the force for moving a motor carrier and a lens is greater than the force for adhering the foreign matter, and the normal starting of the motor is realized under the situation that the foreign matter is existent at the bottom of the motor module motor.

Description

technical field [0001] The invention relates to the field of camera technology, in particular to a solution, system and equipment for foreign matter at the bottom of a motor of a camera module. Background technique [0002] A camera module, especially a camera module of a mobile device, has an automatic focusing function. The auto-focus function is realized by means of a motor, but when there are foreign objects at the bottom of the motor of the camera module, such as glue, etc., it will cause the motor curve to be abnormal, and the camera module will not work normally due to the abnormal motor start curve. [0003] Therefore, how to realize the normal startup of the motor when there is a foreign object at the bottom of the motor of the camera module is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide. The specific plan is as follows: [0005] A solution to ...
