Summary:PURPOSE: An image processing device and a method are provided to recognize a dart text on a bright background and a bright text on a dark background altogether. CONSTITUTION: A local average image generation unit(110) generates a local average image of a processed image. A binarization image generation unit(120) generates a binarization image of the local average image. A ternarization image generation unit(130) generates a ternarization image of the local average image. A filling unit(140) recognizes accessed areas with a second gray scale in the ternarization image. The filling unit fills the accessed areas with a first gray scale or a third gray scale by predetermined rules. A recognition unit(150) recognizes strokes and lines of the image.
