Abstract
In general, embodiments of the invention relate to a method for capturing video frames. The method includes obtaining a depth-data frame of an environment using a depth-sensing camera and an infrared illuminator, where the environment is illuminated by an illumination pattern emitted by the infrared illuminator, obtaining, an infrared illuminator parameterization for the illumination pattern emitted by the infrared illuminator, obtaining a desired frame exposure time, based on a desired frame exposure, determining, based on the infrared illuminator parameterization and the desired frame exposure time, an actual frame exposure time, and after determining the actual frame exposure time, obtaining a frame of the environment using the actual frame exposure time using the infrared illuminator with the illumination pattern.
