Abstract :
Research results on a mainly digitally working autofocus system using an optical module without moving parts are presented. The NMOS chip contains two linear arrays of 52. photodiodes each giving. a resolution of 15 distance ranges between 1 m and infinity. Minimum scene brightness is about 4 cd/m2 (daylight illumination).
