Abstract
A control method for an optical device includes a detector detecting a current position of a lens, a processor calculating a distance between the current position and a target position, the processor determining whether the current position is within a predetermined range according to the distance, and the processor controlling a driving device to move the lens into an allowable range according to whether the current position is within the predetermined range. The predetermined range and the allowable range are corresponding to the target position.
