摘要

A CMOS image sensor (CIS)-based gaze estimation processor (GEP) is proposed for the next-generation user interface (UI) of the smart glasses. It integrates a functional CIS, a RISC, and an ellipse fitting engine (EFE) on a single chip to reduce the power consumption. The functional CIS includes mixed-signal preprocessing circuits, pupil edge detection circuit (PEDC), and glint corner detection cir...
