Provided is an image capturing technology with image correction capability and high document reproducibility that is not affected by how a document is placed or the position of a camera, even where there has been disruption of the color or corners of paper. Image processing with image correction (keystone correction) capability and high document reproducibility is made possible, even where there has been disruption of the color or corners of paper, by printing positioning symbols on document paper when capturing the document, and performing image processing on the basis of the positioning symbols, using a digital camera or a cell phone with a camera, such as a smart phone. |
