摘要： Autofocus device has a lens-driving unit, a focal-point-position-detecting unit that detects a position of a focal point of the lens, and a distance measurement sensor. The sensor measures a distance to a subject based on a reference field of view for distance measurement and a field of view for distance measurement being offset outwardly from the reference field of view and/or a field of view for distance measurement having a field of view that is different from the reference field of view. The device has a control unit that controls the lens-driving unit to drive the lens to meet the position of the focal point of the lens to an in-focus position thereof. The focusing operation starts by setting the lens drive based on a representative value selected from measured distance results obtained by the distance measurement sensor and the position of the focal point of the lens.

摘要： Autofocus device has a lens-driving unit that drives a lens and a focal-point-position-detecting unit that detects a position of a focal point of the lens. The device also has a distance-measuring sensor that measures a distance to a subject and a control unit that performs a focusing operation to control the lens-driving unit to drive the lens, thereby meeting the position of the focal point of the lens detected by the focal-point-position-detecting unit to an in-focus position thereof. The control unit allows to be set a driving direction of the lens and a driving speed of the lens based on the position of the focal point of the lens detected by the focal-point-position-detecting unit and a distance measurement result measured by the distance-measuring sensor. The focusing operation then starts.

摘要： Autofocus device has a lens-driving unit, a focal-point-position-detecting unit, and a distance measurement sensor that measures a distance to a subject. The device also has a control unit for controlling the lens-driving unit to drive the lens, thereby meeting the detected position of the focal point of the lens to an in-focus position. If a restart condition has not yet been satisfied after meeting the position of the focal point to the in-focus position to stop the focus operation, the control unit determines a switch of focusing on subjects based on the detected position of the focal point and a measured distance result by the distance measurement sensor and then restarts the focus operation based on a determination result thereof, thereby driving the lens to meet the position of the focal point to an in-focus position based on a measured distance result by the distance measurement sensor.
