Patent ID: 8693806

Claim:
A computer-implemented method of generating a mosaic digital image from a plurality of pixilated images, the method comprising: defining an output image having a resolution and comprising a plurality of output image portions, each output image portion comprising at least one output pixel; receiving a plurality of input images, each input image of the plurality of input images being of a corresponding ground area of an astronomical body and comprising a plurality of input pixel values; mathematically dividing the ground area of the astronomical body, based on the resolution of the output image, to define a plurality of ground area portions; using ray-tracing mathematics to map each ground area portion of the plurality of ground area portions to a corresponding output image portion of the plurality of output image portions; and assigning values to the at least one output pixel of the output image, based on the mapping of the plurality of ground area portions to the plurality of output image portions and the input pixel values in the plurality of input images.
