Claim:
1. An optical image stabilization (OIS) system comprising: a first camera unit including a lens, an image sensor and an actuator for moving the lens relative to the image sensor along at least two orthogonal axes; a motion sensor separate from the first camera unit including a gyroscope configured to sense angular velocity of the first camera unit on at least the two orthogonal axes; a motion processor configured to determine movement of the first camera unit based at least in part on output from the motion sensor; an OIS controller configured to output a signal corresponding to a compensating relative movement between the lens and image sensor in response to the determined movement of the first camera unit; an actuator circuit for translating the output signal to actuator movement along the at least two orthogonal axes; a digital interface coupling the actuator circuit and the OIS controller; and a host processor configured to run a process utilizing output from the motion sensor, wherein the motion processor is configured to simultaneously provide output to the host processor and the OIS controller.
