  • Pixel arrays and imaging devices with reduced blooming, controllers and methods
    Patent number: 9462202
    Abstract: A pixel array includes regular pixels for imaging, and special pixel sites interspersed among the regular pixels. When the regular pixels become saturated from bright illumination, at least some of their excess charges are removed by the special pixel sites. The removal can reduce or eliminate blooming. In some embodiments, the special pixel sites include special pixels. For imaging, the regular pixels of a group such as a sub-array provide regular outputs that are combined into a composite signal. The special pixels provide a special output. The special output of the group may optionally be added to the composite signal, which can increase the dynamic range.
