Abstract:
An estimate of distance between a user and a camera on a device is used to determine an illumination pattern density used for speckle pattern illumination of the user in subsequent images. The distance may be estimated using an image captured when the user is illuminated with flood infrared illumination. Either a sparse speckle (dot) pattern illumination pattern or a dense speckle pattern illumination pattern is used depending on the distance between the user's face and the camera.

Claim (Index 16):
A device, comprising:\n a camera; a first illuminator providing flood infrared illumination; a second illuminator providing speckle pattern illumination; circuitry coupled to the camera, the first illuminator, and the second illuminator, wherein the circuitry is configured to: illuminate one or more users with flood infrared illumination from the first illuminator; capture at least one first image of at least one user using the while the at least one user is illuminated with the flood infrared illumination from the first illuminator; assess a distance between the at least one user and the camera from the at least one first image; illuminate the at least one user with speckle pattern illumination from the second illuminator, wherein a dot density in the speckle pattern illumination is a first density if the assessed distance is less than a threshold distance between the at least one user and the camera, and wherein the dot density in the speckle pattern illumination is a second density if the assessed distance is greater than the threshold distance, the first density being less than the second density; and capture at least one second image of the at least one user while the at least one user is illuminated with the speckle pattern illumination from the second illuminator.
