Abstract
An image processing apparatus includes a control unit. The control unit performs OCR processing by identifying a specified area of image data as a detection area, detecting line images contained in the detection area, and analyzing the detected line images to identify a character represented by the line images. Furthermore, when failing to identify a character represented by the line images in the OCR processing, the control unit determines whether the line images represent a part of a character and, upon determination that the line images represent a part of a character, expands the detection area in a direction where the other part of the character to be identified is assumed to be present and performs the OCR processing again on the expanded detection area.
