Abstract
A system and method for reading out pixel signals from a multi-color imaging array. The imaging array includes light-sensitive elements which are arranged in rows and columns. Each of the light-sensitive elements is sensitive to photon energy in one of a plurality of spectral regions or color bands. Read-out circuits extract signals representative of an intensity of the photo exposure of the light-sensitive elements at extraction intervals one row at a time. At any particular extraction interval, all of the signals extracted by a particular read-out circuit originate at light-sensitive elements which are sensitive to photon energy in the same spectral region or color band.
