<P>PROBLEM TO BE SOLVED: To provide a charge coupled device (CCD) for reducing power consumption while retaining minimum dark current, having a substantially uniform dark field and flushing of excess current. <P>SOLUTION: A digital camera includes the CCD operating with accumulation mode clocking and two or more clocks operatively and respectively connected to each phase of the two or more phases for initiating flushing of excess current, wherein, to initiate flushing, a time when the clocks are at a high level are substantially the same as capturing an image, and a time when the clocks are at a low level can be selected at any duration between a minimum width at which dark current starts to substantially increase and twice its normal operating duration during image readout. <P>COPYRIGHT: (C)2003,JPO |
