摘要 This is an image processing device that processes images, and that, for an image, sets multiple sets of reference pixels as references and adjacent pixels that are adjacent to these reference pixels. For each difference absolute value for each set, the total of the number of the absolute value of differences that are greater than a preset first threshold value is calculated as the edge volume. When the calculated edge volume is greater than a preset second threshold value, the aforementioned image is distinguished to be a notated image that contains text or symbols, etc. When the aforementioned edge volume is not greater than the second threshold value, the aforementioned image is distinguished to be an image other than a notated image. Therefore, with the present invention, it is possible to suitably distinguish between notated images that contain text or symbols, etc. and non-notated images other than the notated images.
