Abstract
A method of discriminating pictures, wherein a picture is binary-coded. The variation in the number of foreground pixels constituting foreground pixel regions within a discrimination unit area is determined. Alternatively the variation in the distance between said foreground pixel regions is determined. It is then determined by a known relationship whether the discrimination unit area is of a dot gradation picture or not. If the picture is not a dot gradation picture, the rate of background is measured to determine whether the above discrimination unit area is of a line picture or of a continuous tone picture.
