DETECTION DEVICE AND METHOD FOR DETECTING SENSOR SIGNALS IN A GRID OF SENSOR ELEMENTS

摘要

A detection device (2) for detecting at least the occurrence and the location of occurrence of sensor element signals (12) that are generated by sensor elements (15), comprises an array of detector element circuits (11) each generating a element row output (13) and at least one element column output (14). The detection device (2) determines• for each row of detector element circuits (11), at least a first row summation signal (23) corresponding to a sum of the element row outputs (13) of the detector element circuits (11) of this row, and a row address signal (33) indicating, by being in an active state, that the first row summation signal (23) crosses a threshold,• for each column of detector element circuits (11), at least a first column summation signal (25) corresponding to a sum of the element column outputs (14) of the detector element circuits (11) of this column, and a column address signal (34) indicating, by being in an active state, that the first column summation signal (25) crosses a threshold.
