Image data inspecting method and apparatus providing for equal sizing of first and second image data to be compared

摘要

An image data inspecting method detects whether or not a pattern described by a first image data and a pattern described by a second image data match. This method includes the steps of (a) carrying out a sizing process on the first and second image data so that the patterns described thereby are at least enlarged or reduced by the same amount, and (b) comparing the first and second image data which are processed in the step (a) to determine whether or not the processed first and second image data match.
