Assignee: META PLATFORMS TECHNOLOGIES, LLC
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. The apparatus of claim 1, wherein the digital output is a first digital output;
wherein the photodiode is configured to:
store a first portion of the charge as residual charge; and
after being saturated by the residual charge, output a second portion of the charge as overflow charge to the charge sensing unit; and

wherein each pixel cell of the array of pixel cells is configured to:
use the quantizer to quantize the overflow charge stored in the charge sensing unit to generate the first digital output;
transfer the residual charge to the charge sensing unit;
use the quantizer to quantize the residual charge stored in the charge sensing unit to generate a second digital output; and
store the first digital output in the in-pixel memory based on the photodiode being saturated by the residual charge.
