Abstract
A method will be described for using frame transfer (or in some cases full frame) CCD cameras to give improved images in applications where there is relative motion between the camera and object/target/web, etc. This method is similar to TDI (time delay and integration) mode imaging; however, it differs in several ways. It does not give a continuous image strip as does TDI, but instead gives sequences of conventional format images. On the other hand, the method to be described can be used with higher optical image velocities on the CCD since it is not limited by the pixel readout rate as is conventional TDI. Also, since imaging is completed while the object travels over a small portion of the field of view (FOV) rather than the full height of the FOV, the image quality with solid (3D) objects will be better than conventional TDI (assuming the same pixel array for both).
