摘要： Depth sensing imaging pixels include pairs of left and right pixels forming an asymmetrical angular response to incident light. A single microlens is positioned above each pair of left and right pixels. Each microlens spans across each of the pairs of pixels in a horizontal direction. Each microlens has a length that is substantially twice the length of either the left or right pixel in the horizontal direction; and each microlens has a width that is substantially the same as a width of either the left or right pixel in a vertical direction. The horizontal and vertical directions are horizontal and vertical directions of a planar image array. A light pipe in each pixel is used to improve light concentration and reduce cross talk.

摘要： An imager may include depth sensing pixels that provide an asymmetrical angular response to incident light. The depth sensing pixels may each include a substrate region formed from a photosensitive portion and a non-photosensitive portion. The depth sensing pixels may include mechanisms that prevent regions of the substrate from receiving incident light. Depth sensing pixel pairs may be formed from depth sensing pixels that have different asymmetrical angular responses. Each of the depth sensing pixel pairs may effectively divide the corresponding imaging lens into separate portions. Depth information for each depth sensing pixel pair may be determined based on the difference between output signals of the depth sensing pixels of that depth sensing pixel pair. The imager may be formed from various combinations of depth sensing pixel pairs and color sensing pixel pairs arranged in a Bayer pattern or other desired patterns.

摘要： An array camera may be formed from an array of lenses, an array of corresponding apertures, and an array of corresponding image sensors. The array of apertures may be configured so that some image sensors receive light through apertures of different size than other image sensors. Providing apertures of smaller size increases the F/# of an array camera and increases the depth-of-field in a captured image. The array of image sensors may include a near-infrared image sensor. Providing an image sensor array with a near-infrared image sensor may enhance depth information in captured images or increase night vision capabilities of an array camera. Combining an array of image sensors that includes a near-infrared sensor with an array of apertures having different aperture diameters may allow increased depth-of-field imaging, enhanced extraction of depth information from an image, improved night vision, enhanced image clarity or other improvements.
