ABSTRACT:
A method and device having a CCD in which charge multiplication is obtained by applying drive voltages to clocking elements and is arranged to derive the gain provided by the multiplication elements from at least first and second output signals. The CCD is operated at a first voltage or temperature setting, and then a second voltage or temperature setting and the output signals derived with the CCD imaging a substantially constant scene. The gain at a given voltage or temperature setting can then be derived as a function of the different operational voltage of temperature setting. The method and device can also derive the gain as a function of the rate of change of output signal with an operational parameter such as voltage or temperature.
