Abstract
A CMOS image sensor has a pixel array provided with a plurality of unit pixels arranged in a matrix shape of rows and columns. Each of the unit pixels includes a photocharge generation means for generating photocharges by absorbing an external light; and a sensing node for receiving the photocharges transferred from the photocharge generation means, wherein the sensing node of the unit pixel in a previous scan line is shared with a sensing node of a unit pixel in a current scan line in response to a line select signal of the current line.
