Original Abstract Submitted
a method for increasing a dynamic range of a dual-pixel image sensor is described. the method includes detecting an intensity level of a full pixel from a plurality of pixels of an optical sensor, one or more full pixels of the plurality of pixels includes at least two sub-pixels, detecting an intensity level of one or more sub-pixels, detecting that the intensity level of the full pixel of the optical sensor has reached a saturation level of the full pixel, and in response to detecting that the intensity level of the full pixel of the optical sensor has reached the saturation level of the full pixel, computing an extrapolated intensity level of the full pixel based on the intensity level of the one or more sub-pixels.
