PURPOSE:To recognize the characters at a high speed by segmenting these characters with high accuracy and at a high speed. CONSTITUTION:The images are segmented for each line (n2) and then the images of each character element, i.e., the groups of picture elements are segmented (n3). The character elements having the small lateral widths are extracted as the half size candidate characters based on the character size estimated from the size of the character element (n6). Then the half size candidate character strings that satisfy the fixed conditions are extracted as the English word candidates (n7). The picture element features, etc., are extracted in regard of each half size candidate character forming an English word candidate (n8). Based on these picture element features, etc., the English word candidates including the half size candidate characters which are not identical with the half size English letters are deleted out of all. English word candidates and the English word candidates are corrected (n9). Then the segmenting position is corrected in accordance with the half end full size characters respectively (n10). Then the characters are recognized (n11). |
