Abstract:
1. An image processing method comprising: a search step of searching for original digital data stored in storage means on the basis of an input image; an extraction step of extracting difference information by comparing the original digital data retrieved in the search step and the input image; a vectorization step of converting the difference information extracted in the extraction step into vector data; a composition step of compositing the difference information that has been converted into the vector data to the original digital data; and a checking step of checking whether or not to inhibit information about the retrieved original digital data from being changed, wherein if it is determined in the checking step that a change in information is not inhibited, the difference information extracted in the extraction step is converted into vector data in the vectorization step, and the difference information that has been converted into the vector data is composited to the original digital data in the composition step, and if it is determined in the checking step that a change in information is inhibited, the difference information extracted in the extraction step and information other than the difference information which is included in the input image are converted into vector data in the vectorization step.
