A method of controlling exposure time is disclosed comprising receiving an image of an eye from an image sensor, the image resulting from the image sensor detecting light during a first exposure time. A pupil intensity is determined as an intensity of a representation of a pupil of the eye in the image and an iris intensity is determined as an intensity of a representation of an iris of the eye in the image. Furthermore, a pupil-iris contrast is determined as a contrast between the representation of the pupil in the image and the representation of the iris in the image. On a condition that the pupil intensity is determined to meet an intensity condition, an intensity compensated exposure time is determined which is different from the first exposure time, and on a condition that the pupil-iris contrast is determined to meet a contrast condition, a contrast compensated exposure time is determined which is different from the first exposure time. Furthermore, a second exposure time is set based on any determined intensity compensated exposure time and any determined contrast compensated exposure time.
A method of controlling exposure time comprising:
An eye tracking system comprising a circuitry configured to perform the method of:
One or more computer-readable storage media storing computer-executable instructions that, when executed by a computing system that implements eye/gaze data processing, cause the computing system to perform the method of:
