Abstract:
An image processing apparatus comprising:storage means for storing image data comprising color data of respective pixels, and attribute data set corresponding to said image data, said attribute data defining a change in colors;extracting means for extracting said set attribute data from said storage means;determining means for determining a color changing manner of the color data of the respective pixels of said image data based on said attribute data extracted by said extracting means; andchanging means for changing a color of said image data by rewriting the color data of the respective pixels of said image data based on the color changing manner determined by said determining means;wherein said attribute data is set as a data portion of the color data of the respective pixels of said image data stored in the storage means, and said extracting means extracts the attribute data from said image data stored in said storage means; andwherein said storage means stores said image data such that said attribute data has been set to extra bit data which exceeds preselected color resolution among predetermined bit data of the color data of said respective pixels of said image data, and said extracting means extracts the attribute data from the extra bit data contained in the color data of the respective pixels of said image data with respect to each of said pixels.
