A device and method for continuous vertical clocking a charge-coupled device image sensor operating in a time delay and integration and binning mode of operation is disclosed. The method includes providing a charge-coupled device image sensor with a continuous charge transfer signal to a vertical charge-coupled device register for shifting charge continuously to more closely approximate the speed of movement of the target object of capture by the image sensor in order to eliminate artifacts in the TDI imaging direction. The control module of the CCD image sensor provides the continuous charge transfer signal to the vertical charge-coupled device register.
