An edge detecting image sensor architecture

A programme of work at Brighton Polytechnic has concentrated upon the development of binary sensors featuring low to medium spatial resolution, with a view to their application to flexible industrial automation. The programme began with the in-depth study of the IS32, a member of the family of proprietary Optic DRAM (ODRAM) devices from Micron Technology. This was basically a modified 64 kbit dynamic RAM. It also offered random access to its photosites which could then be selectively sensitised. Consideration of these unique properties inspired the design of the edge detecting image sensor architecture presented.<
