<p>PURPOSE:To determine an area occupied by the main part of the characters constituting a character string without any error by employing a histogram which is generated for the character string after being subjected to a specific processing. CONSTITUTION:For every picture element (a) constituting the each character of each character string, the number of picture elements neighboring consecutively including the picture element is counted along the predetermined plural directions D1-D4; identification information 1-4 to identify the direction in which the number of consecutive picture elements is maximum is supplied for each picture element. When a pair of picture elements having special identification information 4 in the special direction D4 along the direction of the character string are connected by the picture element given the identification information along the character string direction, the identification information of the picture element between the pair of picture elements is substituted with the special identification information 4. Then in each character string, the number of the picture elements that are given the special identification information 4 is counted to detect the location of such a picture element that gives the maximum value. In such a way, the area occupied by the main part of each character of a character string can be exactly detected.</p> |
