Patent attributes
An image sensor pixel may include multiple split photodiodes that are covered by a single microlens. The image sensor may include a charge overflow capacitor coupled to a pixel charge storage within the image sensor via a gain control transistor. The image sensor pixel may have phase detection capabilities in a first mode of operation enabled by comparing phase signals generated from the split photodiodes. The image sensor pixel also may generate and readout image signals simultaneously in both rolling shutter operations and global shutter operations in a second mode of operation. The image sensor pixel may also generate an image using a linear combination of at least two signals read out using the charge overflow capacitor and light flickering mitigation operations. The image may be a high dynamic range image that is generated from at least a low exposure signal and a high exposure signal.
