Abstract: The present invention relates to an imaging sensor system (26) having a high detection accuracy. The system (26) comprises a plurality of pixel sensors (1) and at least one light source. The pixel sensors (1) are grouped in clusters, wherein each pixel sensor (1) comprises a photodetector (2) and a local controlling circuit (18). The plurality of sensors (1) in each cluster are configured, using local controlling circuits (18), to output a global detection signal (15) when detecting a local detection signal (10) from at least two outputs of the photodetectors (2) of said cluster. The system (26) has a high detection accuracy due to ruling out false positive detections, since each detection requires at least two positive outputs of the photodetectors (2) of said cluster.

Abstract: The present invention relates to an image sensor (1) for efficient optical sensing. The sensor (1) comprises a plurality of pixel sensors (3), each pixel sensor (3) comprising a photo detector (4), each pixel being adapted to output a digital signal. The sensor (1) further comprises processing means. for example a neural network (5), comprising a plurality of neurons (6). Each photo detector (4) is in the vicinity of said processing means.
