摘要： This is generally directed to systems and methods for reduced metal lines and control signals in an imaging system. For example, in some embodiments a pixel cell of an imaging system can operate without a row select transistor, and therefore can operate without a row select metal control line. As another example, in some embodiments a pixel cell can share its reset transistor control line with a transfer transistor control line of another pixel cell. In this manner, an imaging system can be created that averages a single metal line per pixel cell. In some embodiments, operation of such reduced-metal line imaging systems can use modified timing schemes of control signals.

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： A pixel cell with improved lag characteristics without increased noise. The pixel cell according to embodiments of the invention includes a photo-conversion device and a floating diffusion region switchably coupled to the photo-conversion device. The pixel cell includes a reset transistor, which has a first terminal electrically connected to the floating diffusion region and a second terminal switchably coupled to first and second voltage sources. The first voltage source is higher than the second voltage source. The pixel cell operates by returning a potential on the photo-conversion device to a value approximately equal to a value of a potential barrier between the photo-conversion device and the floating diffusion region prior to generating charge in the photo-conversion device.

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.
