Abstract
A method of operating an image sensor includes generating an analog pixel signal, including a reset component and an image component, based on incident light received by a pixel in the image sensor. Operations are performed to repeatedly sample the reset component of the analog pixel signal using a ramp signal, during a first time interval, and then repeatedly sample the image component of the analog pixel signal using the ramp signal, during a second time interval subsequent to the first time interval. A digital signal corresponding to an effective image component of the incident light is then generated. This digital signal is based on the repeatedly sampled reset component of the analog pixel signal and the repeatedly sampled image component of the analog pixel signal. In addition, during both the first and second time intervals, the ramp signal decreases in magnitude and increases in magnitude.
