Abstract
Apparatus, systems, and methods disclosed herein may transpose image blocks from successively-captured versions of an image according to relative movement between an image capture device and the scene being captured. The transposition may provide for alignment of the successively-captured images notwithstanding the movement. The transposed image blocks from the successive images are composited in the frequency domain by integrating frequency domain coefficients from each into a composite final image. Additional embodiments are disclosed.
