Method and Apparatus for Processing Video Data

Abstract

A method for diagonal processing of video data includes separating diagonally arranged data from rectilinearly arranged data in a video stream, rotating the diagonally arranged data to a rectilinear position; and compressing the rotated diagonally arranged data by a rectilinear compression algorithm. Alternatively stated, the method includes recognizing diagonally arranged data in a video stream, processing the diagonally arranged data into rectilinear data, and compressing the rectilinear data by a rectilinear compression algorithm. An apparatus for diagonal processing of video data includes a demultiplexer receptive to a video stream and developing a plurality of separated color planes, at least one of which is a rectilinear color plane and at least one of which is a rotated color plane, a number of address generators associated with the plurality of color planes, wherein an address generator associated with the rotated color plane is operative to rotate the rotated color plane to a rectilinear position; and a data compressor receptive to the address generators and operative to compress the plurality of color planes with a rectilinear compression algorithm.

What is claimed is: 
     
         1 - 20 . (canceled) 
     
     
         21 . A method for automatically creating address generators comprising:
 generating, by a digital processor, original coordinate pairs specifying an original position of each element in a sensor mosaic;   transforming, by said digital processor, said original coordinate pairs into a sequence of adjusted coordinate pairs which are rectilinearly juxtaposed; and   generating, by said digital processor, a finite state automaton that mimics the sequence of adjusted coordinate pairs.
