Abstract
There is provided a light detection system which is capable of determining in light embedded codes by detecting light in a scene which is illuminated by an illumination system () comprising one or more light sources () each providing a light contribution (I, I, I) comprising an embedded code (ID#1, ID#2, ID#3) emitted as a temporal sequence of modulations in a characteristics of the light emitted. The light detection system comprises light detection means (), which are arranged for acquiring at least one image of the scene, where the image is acquired a plurality of temporal shifted line instances. Each line of the acquired image comprises an instance of the temporal sequence of modulations of the first embedded code. The light detection system further comprises means () for determining embedded codes from the spatial pattern of modulations.
