Abstract:
Techniques for reducing a read out time and power consumption of an image sensor used for eye tracking are described. In an example, a position of an eye element in an active area of a sensor is determined. The eye element can be any of an eye, a pupil of the eye, an iris of the eye, or a glint at the eye. A region of interest (ROI) around the position of the eye is defined. The image sensor reads out pixels confined to the ROI, thereby generating an ROI image that shows the eye element.

Claim (Index 20):
A non-transitory computer readable medium storing instructions that, upon execution on an eye tracking system, configure the eye tracking system to perform operations comprising:\n detecting, from an image generated based on an image sensor, an eye element that comprises at least one of: an eye, a pupil of the eye, an iris of the eye, or a glint at the eye; determining a position corresponding to the eye element in an active area of the image sensor, wherein the active area corresponds to pixels of the image sensor; positioning a region of interest (ROI) within the active area, wherein the ROI is positioned based on the position corresponding to the eye element and is smaller than the active area; and reading out only a subset of the pixels of the image sensor, wherein the subset corresponds to the ROI.
