In an imaging system, intentional scene motion across the image detector from frame-to-frame, and more particularly the rate of intentional scene motion is "decoupled" from smearing of the scene in the detected image by applying the intentional scene motion in the interval between frames to produce the intentional scene motion in a discrete step across the image detector from frame-to-frame. The intentional scene motion may be quantized or provided as a sub-pixel dither signal to control the sub-pixel phase frame-to-frame. In register/sum applications, this substantially eliminates misregistration of the images and may allow for super-sampling of the images onto a higher resolution grid. The ability to decouple intentional scene motion from smearing and to control the sub-pixel phase defines a new trade space that relaxes the limitations on intentional scene motion across the image detector. |
