Image acquisition device with integrated signal processing has photosensitive elements on first layer, circuits in second, lower layer, at least one electrical connection between layers per pixel

摘要

The device has an arrangement of photosensitive elements and a number of circuits for pixel-by-pixel processing of signals generated by the photosensitive elements. The photosensitive elements are arranged on a first layer (10) and the circuits in at least a second, lower layer (20,30), whereby there is at least one electrical connection (15,20) between the layers per pixel.
