摘要： This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S54), converts the obtained vector data into a data format that can be re-used by an application (S55), and registers the converted file in a file server (S56). With this registration process, since the location of the file is settled, that location information is composited on an image to be scanned using an identifier such as a two-dimensional barcode or the like (S48), and the composite image can be printed (S49). Even when the printed document is scanned again, a registered digital file can be easily specified.
摘要翻译：本发明提供以下环境。也就是说，从要复制的文档的图像数据中指定与要复制的文档相对应的原始文档文件，并且基于指定的文件进行打印处理，以防止图像质量的劣化。此外，当没有注册要复制的文档时，执行注册处理以抑制早期的图像质量的劣化。此外，由于文档被转换为矢量数据，因此便利于这种文档的重用，并且即使当进行诸如放大等的图像处理时也能够抑制图像质量的劣化。为此，当不能指定原始数字文件时，本实施例的装置执行向量化处理（S 54），将所获得的矢量数据转换为可由应用重新使用的数据格式（S55），并将转换的文件注册到文件服务器中（S56）。通过该注册处理，由于文件的位置得到确定，所以使用诸如二维条形码等的标识符将该位置信息合成到要扫描的图像上（S48），并且可以打印合成图像（S49）。即使再次扫描打印文档，也可以容易地指定注册的数字文件。

摘要： Stored digital data is searched for on the basis of an input image, difference information is extracted by comparing the retrieved digital data and the input image, and the difference information is composited to the digital data. Digital data generated by composition is stored. When no digital data is retrieved, the input image is converted into vector data, and the image that has been converted into the vector data is stored as digital data. Obtained region segmentation information and an input image are composited, the composite image is displayed on an operation screen of an MFP, and a rectangular block to be vectorized is designated as a specific region from the displayed region segmentation information. A user designates the specific region by designating rectangular blocks in an image using a pointing device.

摘要： An image conversion apparatus for image-converting input color image signals, and outputting the converted signals to an output apparatus, allows execution of a plurality of different color processing operations, checks if an input color image falls within a color reproduction region of the output apparatus, and changes the color conversion processing result to be output depending on whether or not the input color image falls within the color reproduction region of the output apparatus. For example, when the input color image falls within the color reproduction region of the output apparatus, color reproduction color-matched with input color image signals is performed. When the input color image falls outside the reproduction region, color reproduction is performed by color conversion processing assuring highest color reproducibility.
