摘要
A compression process and apparatus includes: generating a background layer by extracting a text region from an input image and removing at least the text region from the input image; extracting a background region corresponding to a color characteristic from a background layer; recording coordinate values of the background region extracted; and storing the background region in a form in accordance with the color characteristic of the background region extracted. Further, a data storage section stores a local background and a page background as information including the background color estimated and the coordinate values of the background region including the background color, each of which local background and page background are included in the background layer. This configuration makes it possible to improve a compression efficiency and image quality.
