An optical navigation device includes a navigation radiation source capable of producing a beam of radiation, and an optical element. The optical navigation device is for identifying movement of an object to thereby enable a control action to be carried out. A sensor is for receiving an image based upon reflected radiation from the navigation radiation source, and at least one illumination radiation source is for illuminating the optical navigation device. The device is operable, in recurrent cycles of at least reset, expose, and readout phases, to activate the at least one illumination radiation source during the reset phase. The reset phase may have the longest duration of the phases.
