Abstract

A computer-implemented method driving an actuator component that drives movement of a movable part relative to a support structure, an image sensor fixed relative to the movable part or the support structure. The image sensor carries out CDS so as to read, offset in time by a sampling period, a reference signal and a light-sensing signal, and outputs a sync signal prior to CDS. The method comprises receiving the sync signal; generating PWM control signals at a PWM frequency substantially equal to an integer multiple of the reciprocal of the sampling period; during a sensing interval, suspending generating PWM control signals to drive the actuator component; and scheduling the sensing interval to start a time delay after receiving the sync signal, such that the sensing interval overlaps with both or neither of a duration of reading the reference signal and a substantially equal duration of reading the light-sensing signal by the image sensor.
