Abstract
Official abstract text for this publication.
An image capturing device includes a lens, a motor to move the lens, and a variety of modules. The variety of modules includes an interface control module, a module to control the lens movement, a determining module, and an analyzing module. The interface control module displays an input interface for inputting control data. The determining module determines an actual position of the lens according to the basic autofocus function. The analyzing module calculates an optimal autofocus position for the control data input, and determines a ratio between the actual position of the lens and the optimal autofocus position as a correction coefficient. When in use, after the correction coefficient has been set, the input control data is firstly modified according to the correction coefficient, and the lens is moved by the actuator to a modified autofocus position according to the corrected control data.
