Claim Text:
1. A method executed on a computing device to control operation of a first lighting device that includes an illumination source and a light sensor, the method comprising: determining if the illumination source is operating in one of: an on mode of operation and an off mode of operation; in response to a determination that the illumination source is operating in the off mode of operation, generating a first light level map from the first light level by applying compressive sensing algorithms to the first light level and generating a second light level map from the second light level by applying compressive sensing algorithms to the second light level, wherein the first light level map identifies ambient light levels in areas illuminated by the illumination source, and wherein the second light level map identifies additional ambient light levels in the areas illuminated by the illumination source; and performing a pixel-to-pixel comparison of the first light map and the second light map to identify movement vectors within the area illuminated by the light pulse, wherein the movement vectors indicate a movement and a direction of the movement of the second entity.
