Reducing roll-induced smear in imagery

摘要

Mechanisms for reducing roll-induced smear are provided. For each frame period of a plurality of frame periods of a detector array, a pixel mask is rotated with respect to the detector array based on a rotational movement of the scene with respect to the detector array to identify a subset of pixels of the detector array. The pixels in the subset of pixels integrate energy from a scene during that respective frame period. The pixels in the subset of pixels are readout during the respective frame period to generate a pixel data set. The subset of pixels is less than all the pixels in the detector array. An image portion of the scene is generated based on the pixel data set. Successive image portions can be combined to form an image of the scene.

for each frame period of a plurality of frame periods of a detector array comprising a plurality of pixels:
rotating a pixel mask with respect to the detector array based on a rotational movement of a scene with respect to the detector array to identify a subset of pixels of the detector array;integrating, by the pixels in the subset of pixels, energy from the scene; andreading out the pixels in the subset of pixels to generate a pixel data set; generating an image portion of the scene based on the pixel data set; and combining successive image portions to form an image of the scene.
