Pixels Of Image Sensors, Image Sensors Including The Pixels, And Image Processing Systems Including The Image Sensors

An image sensor that is configured to operate in global shutter mode, the image sensor comprising:

• a pixel array comprising a plurality of pixels, each of the plurality of pixels outputs a pixel signal corresponding to incident light during a first period;
• a readout circuit that is configured to perform analog-to-digital conversion on the pixel signal to generate a digital pixel signal;
• and
• a timing generator that is configured to control the pixel array and the readout circuit,
• wherein each of the pixels comprises:
• a photo diode that is configured to accumulate photocharges generated therein corresponding to the incident light during the first period;
• a storage diode that is configured to store photocharges accumulated in the photo diode;
• and
• a storage gate that is configured to control transfer of the photocharges accumulated in the photo diode to the storage diode, the storage gate comprising a vertical gate structure extending toward the photo diode.

A pixel of an image sensor, the pixel comprising:

• a photo diode that is configured to accumulate photocharges generated therein corresponding to incident light;
• a storage diode that is configured to store photocharges accumulated in the photo diode, wherein the storage diode and the photo diode are disposed along a first direction;
• and
• a storage gate that is configured to control transfer of the photocharges accumulated in the photo diode to the storage diode, wherein the storage gate comprises a first portion extending in the first direction and a second portion protruding from the first portion and extending toward the photo diode in a second direction that is different from the first direction.
