Abstract
Character normalization is accomplished using a scaling program. Data input to a scaling program are character images and character parameters (height of result buffer frame, character height, character width and character location), and parameters calculated for scaling (the size of a normalized portion to be output; and the top and bottom and the left and right hand spaces of a normalization pattern to be output). In the present invention, normalization is performed by adjusting the parameters, without especially changing the processing flow. A threshold value is provided in accordance with the size and the location of an input character in order to change a calculation method for parameters that are to be transmitted to the scaling program. Since the values at the boundary of the threshold value are continuous, no discontinuity appears in a resultant normalized image that covers the range from small characters to large characters, and seamless normalization is therefore accomplished.
