APPARATUS AND METHOD FOR EYE TRACKING UNDER HIGH AND LOW ILLUMINATION CONDITIONS

摘要

An eye tracking apparatus is operable in both first and second illumination environments where the second illumination is associated with a higher illumination environment than the first illumination. The apparatus includes an image capturer configured to capture an image of a user, an image processor configured to detect an eyepoint of the user in the captured image, and an optical source configured to emit infrared light to the user in a first illumination mode. The image capturer includes a dual bandpass filter configured to allow infrared light and visible light to pass.

1. An eye tracking apparatus, comprising:
an image capturer configured to capture an image of a user; an image processor configured to detect an eyepoint of the user in the captured image; and a controller configured to determine an operating mode based on an ambient illumination and control an operation of at least one of the image capturer and the image processor based on the determined operating mode, the determined operating mode being one of a first illumination mode and a second illumination mode, the second illumination mode associated with a higher illumination environment than the first illumination mode.
