More Information
Summary:The present disclosure provides a photographing device and a focusing method therefor, and a computer-readable storage medium therefor. The focusing method includes, if a first rotation direction is inconsistent with a historical rotation direction: determining a first number of driving steps based on a sum of a preset number of driving steps and a preset number of correction steps first, and controlling the motor to rotate for the first number of driving steps in the first rotation direction, wherein the preset number of correction steps is greater than or equal to the number of idling steps of the motor; and controlling the motor to rotate for the preset number of correction steps in a second rotation direction that is opposite to the first rotation direction. The focusing method for a photographing device of the present application has the advantage of high focus speed.
