Abstract
A history generating apparatus includes an image generating section, an image reading section and a history generating section. The image generating section generates a bitmap first image and generates initial attribute information indicating attributes of respective pixels of the first image. The image reading section reads an image based on the first image formed on paper so as to generate a bitmap second image. The history generating section separates the second image into image regions by attribute indicated by the initial attribute information, performs image processing on each of the image regions according to the attribute and combines the image regions so as to generate a history image.
