Abstract:
An image processing apparatus and method determine whether an error detecting rate of original information extracted from a code image in a read image obtained by reading a sheet on which the code image is formed, is not smaller than a predetermined value. When it is not smaller than a predetermined value, a code image is reproduced from the extracted original information and the code image in the read image is replaced therewith. One example of the code image is a barcode.
