Abstract

In the present invention, a character recognition apparatus (1) is provided which carries out character recognition processing to a gray-scale image obtained by picking up a character string of characters arranged in a specific direction. The character recognition apparatus (1) carries out the character recognition processing for each of characters as Ne (Ne is an integer equal to or more than 2) characters from an end of the character string. In the character recognition of the Ne characters, a plurality of character areas (31) with various character area sizes are set to each position on the gray-scale image and a character recognition result and an evaluation value are calculated for each character area (31). The character recognition apparatus (1) determines the character recognition results and an optimal character area sizes for the Ne characters based on the calculated evaluation values. For the character recognition of the remaining characters, the character recognition apparatus (1) sets the character area having the optimal character area size to each position on the gray-scale image and carries out the character recognition processing.
