Abstract
An anti-aliasing font character on a monitor is prevented from being erroneously judged as an image region. The pixel of interest and four pixels each preceding and following the pixel of interest (a total of nine pixels) are extracted (S). The largest of the values of the sub-pixels of each of the nine pixels extracted is determined as the representative value of each pixel (step S). The nine representative values are represented as a histogram and referred to as H0, H1, H2, and the like in the descending order of the frequency in the distribution (S). Whether Formula (1) below is satisfied is determined (S). H0+H1+H2<TH . . . (1) If Formula (1) is satisfied, the pixel of interest is judged as a non-character-region pixel; if not, the pixel of interest is judged as a character-region pixel (S, S).
