Claim Text:
1. A method for locating light sources, comprising: creating a list of light sources in an arrangement having a plurality of light sources, each of the light sources having a unique digital identifier with a bit sequence having a bit string; simultaneously driving the light sources such that all the light sources are driven within a same clock pulse of a common clock frequency, to cause each of the light sources emits to emit a light sequence of successive light states corresponding to the bit sequence of the unique digital identifier associated with the respective light source such that the light states emitted by the individual light sources correspond, over the course of time, to the bit string of the bit sequence of the respective light source; recording an image sequence of the arrangement by an image recording device during the driving operation; and locating a light source by matching a sequence of images in the image sequence to a sequence of light states in the light sequences corresponding to the associated unique digital identifier of the light source.
