Claim:
1. A camera apparatus comprising: an imaging sensor circuit to produce a sequence of images, each image being produced during a respective sensor frame; a driver mode control circuit coupled to the sensor circuit, to produce a control signal that is asserted during a first predetermined portion of the respective sensor frame and is not asserted during a second predetermined portion of the respective sensor frame; a lens to form a light image on a sensor pixel array of the imaging sensor circuit; an electro-mechanical actuator coupled to move the lens or the sensor pixel array; and a driver circuit coupled to drive the actuator, the driver circuit having a linear drive section and a switch mode drive section, wherein the driver circuit is configured to drive the actuator a) with the switch mode drive section and not the linear drive section when the control signal is asserted, and b) with the linear drive section and not the switch mode drive section when the control signal is de-asserted.
