摘要： A backside illuminated imaging sensor pixel includes a photodiode region, a pixel circuitry region, and a storage capacitor. The photodiode region is disposed within a semiconductor die for accumulating an image charge. The pixel circuitry region is disposed on the semiconductor die between a frontside of the semiconductor die and the photodiode region. The pixel circuitry region overlaps at least a portion of the photodiode region. The storage capacitor is included within the pixel circuitry region overlapping the photodiode region and is selectively coupled to the photodiode region to temporarily store image charges accumulated thereon.

摘要： The present invention provides a method, system and apparatus for a time stamped visual motion sensor that provides a compact pixel size, higher speed motion detection and accuracy in velocity computation, high resolution, low power integration and reduces the data transfer and computation load of the following digital processor. The present invention provides a visual motion sensor cell that includes a photosensor, an edge detector connected to the photosensor and a time stamp component connected to the edge detector. The edge detector receives inputs from the photosensor and generates a pulse when a moving edge is detected. The time stamp component tracks a time signal and samples a time voltage when the moving edge is detected. The sampled time voltage can be stored until the sampled time voltage is read. In addition, the edge detector can be connected to one or more neighboring photosensors to improve sensitivity and robustness.
