Abstract:
An image sensor pixel may include a photodiode, a floating diffusion, and a transfer gate. Column readout circuitry coupled to the image sensor pixel via a column line. The column readout circuitry may include sample and hold circuitry, comparison circuitry, residual measurement and summation circuitry, counter circuitry, analog-to-digital conversion circuitry, and digital summation circuitry. Column readout circuitry is configured to perform readout operations on a pixel image signal generated for a single frame in one or more portions, thereby extending the dynamic range of the imaging system without modifying pixel structure to generate high-dynamic range images within the single frame.

Claim (Index 12):
A system, comprising:\n processing circuitry; input-output circuitry; an array of image sensor pixel that includes a given image pixel having a photodiode configured to generate an image signal in response to incident light, a floating diffusion region, and a transistor interposed between the photodiode and the floating diffusion region; and a readout circuit coupled to the given image pixel via a pixel output line, wherein the transistor is partially activated during readout operations based on a target swing voltage at the pixel output line and wherein the readout circuit is configured to perform the readout operations on an image readout voltage at the pixel output line corresponding to at least a portion of the image signal and to compare the image readout voltage with the target swing voltage.
