Abstract
There are provided an image processing apparatus, a character recognition method and a computer-readable, non-transitory medium that can perform character recognition at high speed while retaining character recognition accuracy. The image processing apparatus includes 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 the input image contains a character component and whether the input image contains the character component and a non-character component, a binarization unit for producing a binary image based on edge strength of each pixel, when the input image contains both the character component and the non-character component, and for producing a binary image based on a luminance value of each pixel, when the input image contains the character component but does not contain the non-character component, and a character recognition unit for performing character recognition on the binary image.
