PROBLEM TO BE SOLVED: To provide an enhanced apparatus and method for measuring gains. SOLUTION: A CCD device of the type for providing charge gain by impact ionization has a multiplication register. Gains provided by a subset of the elements of the multiplication register are independently controllable from other elements in the register. This enables the register to be used in one setting with the same gain applied to all elements and a different setting with a subset of elements arranged to provide a different gain. By comparing the two signals, the gain provided by the register can be derived. COPYRIGHT: (C)2007,JPO&INPIT
