COMPRESSED DOMAIN IMAGE SUMMATION APPARATUS, SYSTEMS, AND METHODS
First Claim
Patent Images
1. An apparatus, comprising:
- a strip buffer to temporarily store an image data stream associated with a new version of an image as the image data stream is received from an image sensor array (ISA);
an image comparator to compare a selected set of low-frequency coefficients of a new frequency domain (FD) image block associated with the new version of the image to a corresponding set of low-frequency coefficients of an earlier-stored composite FD image block associated with at least one previously received version of the image; and
combinational logic to combine the new FD image block with the earlier-stored composite FD image block to yield a new composite FD image block if the selected set of low-frequency coefficients of the new FD image block match the corresponding set of low-frequency coefficients of the earlier-stored composite FD image block within a match threshold.

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.
