Claim Text:
1. An integrated circuit comprising a substrate having a major surface; a directional light sensor, the directional light sensor comprising a plurality of photodetectors on a region of said major surface, said plurality of photodetectors comprising a set of first photodetectors for detecting light from a first direction and a set of second photodetectors for detecting light from a second direction, wherein a first photodetector in the first set is located adjacent to a second photodetector in the second set; and a light blocking structure comprising: a first portion extending from said major surface in between the first photodetector and the second photodetector; and a second portion extending from the first portion and at least partially overhanging at least one of the first photodetector and the second photodetector; and a plurality of clusters of photodetectors, each cluster comprising a photodetector from the first set adjacent to a photodetector from the second set; wherein said clusters are organized along respective edges of said region, the integrated circuit further comprising a further light sensor at least partially located in a central part of said region, wherein neighboring clusters along a same edge of the region are spatially separated by a portion of the further light sensor.
