Abstract:
A method of reading a pixel value from an image sensor housed with a set of components includes determining a current state of the set of components; adjusting, at least partly responsive to the current state of the set of components, a correlated double sampling (CDS) time; and performing, in accordance with the adjusted CDS time, a CDS readout of at least one pixel in a pixel array of the image sensor.
