Abstract

An image processing method for recognising characters included in an image. A first character recognition unit performs recognition of a first group of characters corresponding to a first region of the image. A measuring unit calculates a confidence measure of the first group of characters. A determination unit determines whether further recognition is to be performed based on the confidence measure. A selection unit selects a second region of the image that includes the first region, if it is determined that further recognition is to be performed. A second character recognition unit performs further recognition of a second group of characters corresponding to the second region of the image.
