Patent ID: 11950011
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. The image sensor of claim 8, which is configured to, during a time interval of a low conversion gain (LCG) mode within a readout period of the first photodiode,
turn on the sample transistor and the first select transistor to output the amount of reset charges stored in the second capacitor as a reset signal,
after outputting the reset signal, turn on the second reset transistor to reset the second capacitor,
after resetting the second capacitor, turn off the second reset transistor and turn on the sample transistor to store the amount of overflow charges in the second capacitor,
after storing the amount of overflow charges in the second capacitor, turn off the sample transistor and the first select transistor and turn on the first reset transistor to reset the second floating diffusion node, and
after resetting the second floating diffusion node, turn off the first reset transistor and turn on the first select transistor and the sample transistor to output the amount of overflow charges stored in the second capacitor as an image signal.
