Claim One:
1. An eye detection system comprising: at least one illuminator element adapted to emit light in a direction towards the head of a user; at least one image sensor being adapted to receive light from the illuminated head of a user and repeatedly capture pictures, each being represented by a digital image frame comprising a matrix of picture elements; a plurality of eye detection units connected to said image sensor, said eye detection units being adapted to receive subsets of picture elements of a digital image frame substantially in parallel and wherein said eye detection units are adapted to operate substantially in parallel, each eye detection unit being adapted to receive a selected subset of the picture elements of at least one digital image frame and including an eye feature extraction module adapted to perform a eye feature extraction process on the received picture elements to identify predetermined eye features; and an eye data generating module connected to said eye detection units and being adapted to: receive information of potential identified eye features from said eye detection units, said information including picture element coordinates for said identified eye features, and the received region of picture elements, generate eye data based on said information of potential eye features, wherein said eye data is generated if identified eye features fulfil predetermined conditions, and transfer generated eye data and the received regions of picture elements to a processing module, and wherein a data flow of said eye data and the region of picture elements of a digital image frame is substantially parallel.
