ABSTRACT:
A character extraction apparatus is provided for extracting character data for each character from a text image which is represented by first pixels corresponding to character images and second pixels corresponding to background images. The character extraction apparatus comprises a character row detecting means for detecting character rows from the text image and obtaining position data of each character row; a pixel array extracting means for extracting arrays of continuous first pixels in an area specified by the character row position data and computing position data of each of the arrays of continuous first pixels; a character array linking means for linking the arrays of continuous first pixels in the area based on the position data of the arrays of continuous first pixels; and a character extracting means for recognizing each set of arrays of continuous first pixels linked by the character array linking means as a character and outputting character data.
