Patent ID: 7737388

Claim:
A method, comprising: resetting a first photodiode of a first pixel and placing a first floating diffusion of the first pixel in a high bias state, including maintaining a first reset transistor and a first transfer transistor of the first pixel in an on state during a first period of time while supplying a high supply voltage to a channel terminal of the first reset transistor during the first period of time, wherein the first pixel is in a first row of pixels of an imaging device; integrating charge in a previously reset second photodiode of a second pixel during the resetting of the first photodiode and before reading out the second pixel, including maintaining a second transfer transistor of the second pixel in an off state while maintaining a second floating diffusion of the second pixel in a low bias state during the first period of time, wherein the second pixel is in a second row of pixels of the imaging device; initiating charge integration in the first photodiode after the resetting of the first photodiode and before reading out the first pixel, including turning off the first transfer transistor of the first pixel after the first period of time; and placing the first floating diffusion of the first pixel in a low bias state after the initiating of the charge integration in the first photodiode and before reading out the first pixel, including maintaining the first reset transistor in an on state during a second period of time, after the first period of time, and supplying a low supply voltage to the channel terminal of the first reset transistor during the second period of time.
