IMAGE SENSORS WITH REDUCED NOISE
An image senor may include an array of pixels controlled by row control circuitry. Each pixel may include a photodiode for generating image signals and a charge storage structure coupled to a floating diffusion region and configured to generate and store parasitic light noise level signals. The imag...

| description | An image senor may include an array of pixels controlled by row control circuitry. Each pixel may include a photodiode for generating image signals and a charge storage structure coupled to a floating diffusion region and configured to generate and store parasitic light noise level signals. The image signals and the parasitic light noise level signals may be read out in the same readout cycle using shared or separate readout circuitry. Processing circuitry may selectively process the image signals based on the parasitic light noise level signals to generate image signals with reduced noise. |
