Abstract:
An encoding device includes a binary image generation unit that generates at least two binary images from a multivalued image by applying different methods, a check image generation unit that generates a check image based on the plural binary images generated by the binary image generation unit, and a code generation unit that generates coded data by encoding at least one of the binary images generated by the binary image generation unit and the check image generated by the check image generation unit by using different methods.
