Abstract

A time-of-flight camera system is described. The time-of-flight camera system includes an illuminator to illuminate a region within the time-of-flight camera system's field of view. The time-of-flight camera system includes an image sensor to receive optical signals from the illumination for determining depth profile information within the field of view using time-of-flight measurement techniques. The image sensor has circuitry to determine one or more regions within the field of view where a received optical signal from the illuminating was weak. The illuminator is also to re-illuminate the one or more regions with stronger light than the one or more regions received during the illuminating. Each of the one or more regions being smaller than the region. The image sensor is also to receive optical signals from the re-illumination for determining depth profile information within the one or more regions.
