Information processing apparatus, storage medium, and information processing method for character recognition by setting a search area on a target image

A non-transitory computer-readable storage medium storing a computer program that causes a computer to perform:

• first setting for setting a search area on a recognition target image;
• second setting for setting cutout areas at a plurality of positions in the search area;
• and
• character detection for extracting images respectively corresponding to the plurality of cutout areas, obtaining an approximation straight line based on the positions of the cutout areas output as recognition results of other characters, obtaining similarities of candidate characters by comparison between the extracted images and dictionary data, obtaining evaluation values of the candidate characters by weighting the obtained similarities of candidate characters based on distances between the positions of the respective cutout areas and the obtained approximation straight line, and outputting, as a recognition result, a candidate character with a highest evaluation value among the obtained candidate characters,
• wherein in the first setting, a search area relating to a next character is set based on position information about the cutout area corresponding to the output recognition result in the character detection.
