CORRELATED MULTIPLE SAMPLING CMOS IMAGE SENSOR

A CMOS image sensor including at least one pixel and one circuit arranged to receive, on a first node of the circuit, an analog signal representative of the luminosity level received by the pixel, the circuit being capable of successively acquiring 2n samples of said signal, n being an integer greater than or equal to 1, and of delivering, on a second node of the circuit, an analog signal having a value equal to the average of the values of said samples, without generating an intermediate signal having a value greater than the value of the largest acquired sample - See more at: http://www.patentbuddy.com/Patent/20160014361#sthash.bNrCRrHJ.dpuf
