Abstract
A method of operating an imaging system is described. The method comprising transferring first image charges accumulated during a long exposure period of a first image frame to respective floating diffusion regions of a first pixel and a second pixel, reading out long exposure image signals from the respective floating diffusion regions to a first storage capacitor associated with the first pixel and a second storage capacitor associated with the second pixel, transferring second image charges accumulated during a short exposure period of the first image frame to the respective floating diffusion regions of the first pixel and the second pixel, reading out a short exposure image signal from a corresponding one of the floating diffusion regions to the second storage capacitor, and reading out storage charge signals from the first storage capacitor and the second storage capacitor to generate image data for the first image frame.
