ABSTRACT:
A pattern matching system, comprising a receiver, a comparison block, a calculation block, an output block, a ratio reading block, and a controller, is provided. A likeness value indicates how much a first and second image accords to each other. The receiver receives first and second image signal corresponding to the first and second images as an area signal. The comparison block compares the signal levels of the area signals corresponding to the pattern areas at the relatively same location of the first and second images. The calculation block calculates the likeness value. The ratio reading block reads a amplification ratio by which the first and second image signals are amplified. The controller changes the type of the signal components of the area signal used for the comparison by the comparison block and the calculation of the likeness value by the calculation block.
