Beschreibung
Zusammenfassung:	A device for controlling illumination of a scene using an LED array that includes a plurality of individually addressable LEDs, built into a hand-held device, is disclosed. The device includes a controller arranged to configure a first sub-set of the LEDs to provide illumination for a target spot in the scene and to monitor movement of the hand-held device. If the controller detects movement of the hand-held device while the first sub-set of the LEDs is providing illumination, then the controller may configure a second sub-set of the LEDs to continue providing illumination of the target spot. In this manner, even though there may have been movement that could change the specific area illuminated by the LED array, the movement is compensated for, at least partially, by selecting one or more other LEDs to illuminate the same target spot in a manner that is substantially unnoticeable to the user.
