1. A method of reading a charge coupled device (CCD) image sensor operating in a multiple exposure time delay integration (TDI) mode for capturing images including an object having a rate of movement relative to the CCD, the method comprising: time delay integrating the CCD for a first number of cycles; reading a first frame of images from the CCD; time delay integrating the CCD for a second number of cycles different from the first number of cycles; reading a second frame of images from the CCD, wherein the CCD includes a number of lines of pixels and the time delay integrating the CCD for the first number of cycles includes: transferring pixel charges from a pixel to a vertical shield charge storage register of the CCD once for each cycle of the first number of cycles; and shifting the vertical shield charge storage register for an at least one shift each cycle of the first number of cycles, and the reading the first frame of images from the CCD includes shifting the vertical shield charge storage register by an amount equal to or greater than the number of lines of pixels.
