Abstract
A camera may include an actuator driver system comprising at least two drivers to generate current for individual coils of one or more actuators of the camera. One driver may act as a primary driver, whilst the other may serve as a secondary driver. The primary driver may receive at last one command signal from a host and at last one measurement signal from a sensor. The primary driver may determine command current for the individual coils according to the command and measurement signals. The primary driver may distribute between the two drivers signals indicative of the determined current for the coils. Accordingly, the first and second drivers may respectively generate the current for the corresponding coils connected with the drivers to move at least one lens and/or an image sensor of the camera.
