Abstract

A smart image sensor with a size of 6.5 mm X 8.2 mm has been designed by a 2-metals 1-poly 0.7 micrometers CMOS process. It consists of a 16 by 16 photodiode array for picking up the piles, and each pixel is in parallel with a time multiplexed edge detector and a 4-bits memory cell. This parallel structure defines the fill factor is of 1.79 percent. 4 LPGCP-ALUs are used for motion vector estimation on the whole focal sensor plane with a switching logic for shifting the LPGCP-ALU window in the area where motion vectors are detected with a sped of the same as the frame rate.
