ABSTRACT:
In an image encoding apparatus, an image area separating section determines for each pixel whether an input original image is a line image or a plane image and outputs separation information representing a type of image for each pixel. A line image position information encoding section encodes the separation information and outputs coded line image position information. A line image generating section extracts a line image from the input original image on the basis of the separation information. A line image color information quantizing section quantizes the line image and outputs quantized line image color information. A line image color information encoding section encodes the quantized line image color information and outputs coded line image color information. A plane image generating section extracts a plane image from the input original image on the basis of the separation information. A plane image quantizing section quantizes the plane image and outputs quantized plane image information. A plane image encoding section encodes the quantized plane image information and outputs coded plane image information. An image decoding apparatus is also disclosed.
