Abstract:
According to one embodiment, the present invention relates to an integrated chip for detecting eye movement. An eye tracker device may include a CMOS image sensor which provides an imaging process of a user's eye image. The eye tracker device may be implemented on a single chip where pixel-level image processing is performed, thereby achieving high operating speed. A smart CMOS Image Sensor (CIS) pixel array may include a CMOS image sensor with a “shrink” function of locating a center of a pupil while eliminating influence of a black region around the eyebrow or pupil at the pixel level so as to accurately find the location at which a user views. The CIS pixel array may include an “expand” function of removing glint or other interference occurring in the pupil due to external light or other source.
