ALEXANDRIA, Va., Aug. 5 -- United States Patent no. 12,701,336, issued on Aug. 4, was assigned to Apple Inc. (Cupertino, Calif.).
"High dynamic range image sensor with dual-carrier pixel architecture" was invented by Jiaju Ma (Arcadia, Calif.) and Xin Yue (Monrovia, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A high dynamic range camera device has an image sensor that implements readout circuitry to read out, for individual pixels of the sensor, two values that are based on two different types of charge carriers produced in response to a light exposure. The two readout values are read from two floating diffusion nodes of the pixel photodiode designed to collect the two types of charge carriers (ele...
