Abstract:
1. An image processing apparatus comprising: a histogram generator for generating a histogram based on a pixel value of each pixel in an input image; a component judging unit for judging whether said input image contains a character component and whether said input image contains a non-character component which is other than said character component and a background component, based on said histogram; a binarization unit for producing a binary image in accordance with a first process that binarizes said input image based on edge strength of each pixel, when said input image contains both said character component and said non-character component, and for producing a binary image in accordance with a second process that binarizes said input image based on a luminance value of each pixel, when said input image contains said character component but does not contain said non-character component; and a character recognition unit for performing character recognition on said binary image.
