Abstract
According to one aspect, embodiments herein provide a TDI image sensor comprising an array of light sensing elements, at least one clock, and an image processor, wherein the at least one clock is configured to operate a first plurality of the light sensing elements to transfer accumulated charge to an adjacent element at a first phase and to operate a second plurality of the light sensing elements to transfer accumulated charge to an adjacent element at a second phase, and wherein the image processor is configured to read out a first signal from the first plurality of light sensing elements corresponding to a total charge accumulated at the first phase, to read out a second signal from the second plurality of light sensing elements corresponding to a total charge accumulated at the second phase, and to combine the first signal and the second signal to generate an image.
