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 21):
A method, comprising:\n capturing a first image using a camera located on a device, the device comprising a computer processor and a memory, wherein the first image comprises an image captured while illuminating with flood infrared illumination from a first illuminator located on the device; determining a distance between a user and the camera by assessing two-dimensional information in the first image; and illuminating the user with patterned illumination having a first pattern density from a second illuminator located on the device in response to the determined distance being less than a threshold distance, wherein the second illuminator is configured to project one of the first pattern density or a second pattern density, the first pattern density being less than the second pattern density.
