Development of Bi-Directional Type Autofocus Actuator for Cameras
Alps Electric has announced the development of “ATMC1Z9”, a Bi-directional type Autofocus Actuator for cameras for integration into 13-megapixel smartphone camera modules. The new product achieves low power consumption as well as a low profile.
Bi-direction type actuators set the initial position of the lens at a frequently used focal distance. They adjust focus by moving the lens from that point in one direction or the other (bi-directionally) depending on whether the current is positive or negative. This process will shorten the distance the lens has to travel, resulting in reduction in amount of power required to move the lens while enabling high-speed focusing.
ATMC1Z9 principal applications include camera modules for smartphones, camera integrated office equipment.
