Vision chips continue to aggressively follow the complexity of nanochips. The smartphone vision-chips of 2014 exceeded 16 Mega-pixels, irrespective of the optical-resolution limits of their lenses with focal lengths of 5 mm or less. At 24- to 48-bit per pixel, this volume of video data is about to flood the Internet, where video already exceeds 70 % of the traffic and >90 % of the data stored. On the other hand, high-sensitivity, high-dynamic-range CMOS (HDRC) human-vision-inspired sensors have maintained pixel sizes of 25 µm2 for ASA 12.800 sensitivity and 1000-by-2000 pixels complexity as well as high-speed global-shutter read-out. HDRC two- and three-chip stereo cameras have become key components for safe and intelligent man-machine cooperation. New compression standards will be needed. More efficient in the long run will be a fundamental review of electronic vision, following human vision with its incredible compression skills. Remarkable benefits from nm technology nodes were achieved for high-resolution time-of-flight (TOF) 3D-vision sensors offering >400-by-600 pixels resolution. TOF-3D and professional stereo cameras enable safe, autonomous mobility and robotics. |
