1. A method performed by a computing device having a processor and memory for combining a first frame and a second frame, comprising:

  • determining by the computing device horizontal and vertical offsets for spatially aligning the first and second frames, comprising summing absolute values of color differences between the first frame and the second frame at a multiplicity of pixel locations, based on trial values for horizontal and vertical offsets;

    further determining by the computing device brightness and contrast parameters for chromatically aligning the first and second frames; and

    generating by the computing device a panoramic image, comprising compositing a portion of the second frame onto a portion of the first frame, based on the horizontal and vertical offsets and based on the brightness and contrast parameters.
