Image processing apparatus and method determines attributes of image blocks based on pixel edge intensities relative to normalized and fixed thresholds

An image processing device for processing a read image and outputting data based on the read and processed image, by any one of output methods including printing and transmission to an external device under control of a control unit, comprising:

• a partial image extracting unit for extracting data corresponding to a partial image of said read image on the basis of a designated area;
• a designated attribute information including a character size, a character color or a character style;
• or a designated character string;
• a displaying unit for displaying the extracted partial image;
• a judging unit for judging whether said partial image has been extracted correctly or not on the basis of the displayed partial image;
• and
• a correcting unit for correcting said partial image according to a designated area, when judging said partial image has not been extracted correctly,
• wherein said control unit outputs the data corresponding to said partial image by any one of the output methods when judging said partial image has been extracted correctly, or after correcting said partial image by said correcting unit.
