Abstract
Disclosed is a method of synchronising an image sensor with a PWM driver operable to drive an arrangement associated with the image sensor, wherein at least one synchronisation signal produced by the image sensor is used to reset the PWM driver and the at least one synchronisation signal is delayed before being used to reset the PWM driver such that the switching on or off of the at least one synchronisation signal occurs at a defined time in relation to a sensitive period of the image sensor's operation.
