Abstract
An image processing apparatus includes an image data input mechanism which allows an input of image data and processes input image data in a unit of pixels. A determination mechanism analyzes and determines whether surrounding pixels close to an object pixel are part of a character area. A calculation mechanism calculates a distance value from the object pixel to the surrounding pixels determined as part of the character area by the determination mechanism. A signal output mechanism outputs a multiple value signal representing a feature of the object pixel as a character based on the distance value calculated by the calculation mechanism.
