    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.

    Abstract translation: 在便携式照相机装置中,可变电压调节器产生VCM驱动器电路的电源电压,其作为光学图像稳定(OIS)机制的一部分传导VCM致动器的线圈电流。 当相机设备从静态捕捉模式或预览模式转换到视频捕获模式时,处理器发信号通知可变电压调节器以增加电源电压,其中增加导致VCM OIS执行器的行程增加。 还描述和要求保护其他实施例。
