    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.

    Abstract: Example virtual-reality head-mounted devices having reduced numbers of cameras, and methods of operating the same are disclosed herein. A disclosed example method includes providing a virtual-reality (VR) head-mounted display (V-HMD) having an imaging sensor, the imaging sensor including color-sensing pixels, and infrared (IR) sensing pixels amongst the color-sensing pixels; capturing, using the imaging sensor, an image having a color portion and an IR portion; forming an IR image from at least some of the IR portion from the image; performing a first tracking based on the IR image; forming a color image by replacing the at least some of the removed IR portion with color data determined from the color portion of the image and the location of the removed IR-sensing pixels in the image; and performing a second tracking based on the color image.
