Title: Computer-implemented method of generating PWM control signals, and corresponding computer program, computer-readable storage medium and apparatus
Inventor: CHRIS AVERY
IPC: H04N5/376
Filed: 2020-12-14
Abstract: A method for 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 support structure. The image sensor carries out correlated double sampling, CDS, to read, offset in time by a sampling period, a reference signal and light-sensing signal, and outputs a sync signal prior to CDS. The method comprises: receiving the sync signal; generating pulse width modulated, PWM, control signals to drive the actuator 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 generating a measurement pulse to measure an electrical characteristic of the actuator; and scheduling the sensing interval to start a time delay after receiving the sync signal, setting the time delay and duration of the sensing interval 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.
