Abstract
A CMOS image sensor is provided with a first pixel group and a second pixel group The first pixel group composed of a plurality of pixels arranged in a matrix at specified pitches PH and PV in the horizontal and vertical directions, respectively. The second pixel group composed of a plurality of pixels arranged similarly in a matrix shifted by about one-half of the pitches PH and PV in the horizontal and vertical directions, respectively from the matrix of the first pixel group. Each of these pixels is composed of a combination of a photodiode PD, a reset transistor RS, a driver transistor D and an address transistor AD. The reset transistors RS belonging to the first and second pixel groups and arranged in a corresponding row of the matrix are connected to a common reset line RSL. Similarly, the address transistors AD belonging to the first and second pixel groups and arranged in a corresponding row of the matrix are connected to a common address line ADL. Further, drain electrodes of two reset transistors RS contained in adjacent four pixels and drain electrodes of two address transistors are connected to a common reset drain voltage line terminal RD.
