BINARY PICTURE DISTORTION CORRECTION PROCESSING SYSTEM

摘要

PURPOSE:To shorten the distortion correction processing time by converting a binary picture into a set of run length vectors and applying distortion correction processing to each run length vector. CONSTITUTION:A start and an end point of each run length vector are subject to affine transformation to obtain a black link picture element taking a start point and an end point of a newly obtained run length vector as a vector. The method to generate one vector (straight line segment) generates a blank link picture element string at a high speed. This is because a line of affine transformation is transformed into a straight line segment when only the start and end point of the straight line segment are subject to affine transformation. That is, a run length vector processing device 4 and a run length vector distortion correction processing 2 (affine transformation processing) are well combined. Thus, only the start and end point to express the run length vector has only to be subject to distortion conversion processing and a binary picture is subject to distortion correction 5 at a high speed.
