Dark current generation in a field-transfer type CCD imager is measured by integrating the response to charge packets supplied from its output register during certain portions of field retrace intervals. During these portions of the field retrace intervals the output register is dynamically clocked to transfer charge packets therefrom although the output register is cleared of externally generated charge. Accordingly, these charge packets originate from the accumulation of dark current arising in the C register.
