Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 19:
20. The image sensor of claim 19, which is configured to, during a time interval of a low conversion gain (LCG) mode within a readout period of the first photodiode,
turn off the third select transistor and turn on the second select transistor to output the amount of reset charges stored in the second capacitor as a reset signal,
turn off the second select transistor and turn on the reset transistor to reset the second capacitor,
after resetting the second capacitor, turn off the reset transistor and turn on the sample transistor to store the amount of overflow charges in the second capacitor, and
after storing the amount of overflow charges in the second capacitor, turn off the sample transistor and turn on the second select transistor to output the amount of overflow charges stored in the second capacitor as an image signal.
