A device includes a display and a first light source configured to emit light, wherein the first light source is proximate to the display. The device further includes a first camera disposed behind the display, wherein the first camera is configured to detect reflections of the light emitted by the first light source. The first camera is further configured to capture a first image based at least in part on the reflections, wherein the reflections are partially occluded by the display. The device also includes a second camera proximate to the display, wherein the second camera is configured to capture a second image. In addition, the device includes a depth map generator configured to generate depth information about one or more objects in a field-of-view (FOV) of the first and second cameras based at least in part on the first and second images.

Various embodiments of a 3D+imaging system include a focal plane array with in-pixel analog storage elements. In embodiments, an analog pixel circuit is disclosed for use with an array of photodetectors for a sub-frame composite imaging system. In embodiments, a composite imaging system is capable of determining per-pixel depth, white point and black point for a sensor and/or a scene that is stationary or in motion. Examples of applications for the 3D+imaging system include advanced imaging for vehicles, as well as for industrial and smart phone imaging. an extended dynamic range imaging technique is used in imaging to reproduce a greater dynamic range of luminosity.

A head mounted display (HMD) is provided. The HMD includes a housing and a view port of the housing. The view port has a screen for rendering an augmented reality scene. Included is a communications device for exchanging streaming data over a network. A depth camera integrated in the housing and oriented to capture depth data of an environment in front of the housing is included. A processor is configured to use the depth data captured by the depth camera to identify spatial positioning of real objects in the environment. A real object is rendered into the augmented reality scene, and the real object is tracked such that insertion of augmented reality objects are placed in coordination with movements of the real object shown in the augmented reality scene. The real object captured by the depth camera is the environment where a user wearing the HMD is located.
