ABSTRACT:
A method, apparatus and computer program product for extracting the line of text to be read, and compensating for any inclination or shifting in the column direction of the scanned character images, to improve the recognition ratio of the character recognition process. By extracting the characters at or near the column-direction center of plural meandering lines of scanned character images, the lines intended to be read for character recognition can be extracted based on the extracted characters. When there is shifting in the column direction between character images on the same scanned line, the amount of shifting is determined based on the inclination between the characters to compensate the shifting based on the obtained inclination. When the scanned character images are skewed relative to the column direction, a process minimizing the slope of the inclination is executed to compensate the inclination.
