一种方法将被描述为使用帧传输（或在某些情况下，全帧）CCD相机，以改善图像的应用程序中，有相机和对象/目标/网络等之间的相对运动，这种方法是类似的TDI（时间延迟和积分）模式成像，但是，它在几个方面有所不同。它不像TDI那样提供连续的图像带，而是提供传统格式的图像序列。另一方面，由于所述方法不像常规TDI那样受像素读出速率的限制，因此可以在CCD上以更高的光学图像速度使用所述方法。此外，由于成像是在物体在视场（FOV）的一小部分而不是FOV的整个高度上行进时完成的，因此固体（3D）物体的图像质量将优于传统TDI（假设两者具有相同的像素阵列）。
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).
