N2 - An image sensor architecture with an alternative image scan method, based on Morton (Z) order, is presented. This scan, compared to the conventional row (raster) scan, enables faster and efficient mean (average) computation of square image blocks. Digital averaging is used and the pixel data is read out with either the original resolution, a 2×2 or a 4×4 block averaging. A test chip of 128×128 array has been implemented in 0.35 μm CMOS technology, has 15% fill factor, is operated by a 3.3V supply and dissipates 30mW at video rate
