Abstract
The present disclosure relates to a pupil positioning device and method and a display driver of a virtual reality device. The pupil positioning device includes a preprocessing circuit and a coordinate processing circuit. The preprocessing circuit is configured to receive an eye image, and preprocess the eye image to obtain all boundary points of the eye image. The coordinate processing circuit is configured to perform connected region processing on all the boundary points, and determine coordinates of a center of the pupil according to the maximum connected region.
