ABSTRACT:
The real-time polar controlled video processor electronically rotates scene nformation in a real-time video processor. By dynamically specifying the origin of each desired consecutive output line from subpixel space, and by specifying the delta "X" and delta "Y" inputs (of X-Y Cartesian coordinates) to a real-time coefficient generator, a subpixel generator can sweep through a stored image database at any arbitrary angle and scale factor. Subpixels which are generated sequentially describe any image size, orientation, and position. This scheme allows dynamic line-by-line accommodation of dynamically rotating sensor outputs.
