Abstract
In a portable camera device, a variable voltage regulator produces a power supply voltage of a VCM driver circuit that conducts the coil current of a VCM actuator as part of an optical image stabilization (OIS) mechanism. A processor signals the variable voltage regulator to increase the power supply voltage when the camera device transitions from still capture mode or preview mode to video capture mode, where the increase causes an increase in stroke of the VCM OIS actuator. Other embodiments are also described and claimed.
