ABSTRACT:
Image data from a transported bill is read in response to a sampling clock and is stored. A clock generator generates a master clock faster than the sampling clock. The degree of skew of the bill is calculated in synchronism with the master clock. The stored image data is then corrected with the results of the skew calculation. The skew-corrected image data is then compressed and compared with predetermined dictionary data in order to recognize the bill.
