Abstract
An image system with a dual layer photodiode structure is provided for processing color images. In particular, the image system can include an image sensor that can include photodiodes with a dual layer photodiode structure. In some embodiments, the dual layer photodiode can include a first layer of photodiodes (e.g., a bottom layer), an insulation layer disposed on the first layer of photodiodes, and a second layer of photodiodes (e.g., a top layer) disposed on the insulation layer. The first layer of photodiodes can include one or more suitable pixels (e.g., green, blue, clear, luminance, and/or infrared pixels). Likewise, the second layer of photodiodes can include one or more suitable pixels (e.g., green, red, clear, luminance, and/or infrared pixels). An image sensor incorporating dual layer photodiodes can gain light sensitivity with additional clear pixels and maintain luminance information with green pixels.
