device and method for suppression of thermal noise in a linear cmos image sensor

摘要

A method of reading out a pixel signal from a pixel is disclosed. The method comprises first capturing a first black reference signal from the pixel prior to the pixel starting an integration period. Next, after completion of the integration period, a pixel signal is captured. Next, a second black reference signal is captured following completion of the integration period. Finally, the first black reference signal, second black reference signal, and pixel signal is output. IMAGE
