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： According to this invention, encoded data of a target data amount is generated by one image input operation while both lossless encoding and lossy encoding are adopted. For this purpose, a first memory stores encoded data of a shorter encode length among encoded data generated by a first encoding unit which performs lossy encoding and encoded data generated by a second encoding unit which performs lossless encoding. A second memory stores encoded data from a second encoding unit. When an encoding sequence control unit determines that the encoded data amount in the first memory has exceeded the target data amount, the encoding sequence control unit discards data in the first memory, sets a quantization parameter for a higher compression ratio for the first encoding unit, and causes the first encoding unit to execute encoding. Encoded data before the encoded data amount is determined to have exceeded the target data amount is re-encoded by a re-encoding unit.

摘要： A color image processing apparatus converts a first color signal (RGB signal) stored in a frame memory for displaying on, e.g., a CRT color monitor into a third color signal (R′G′B′ signal) whose color image information is used for permanent visible representation by a printer, and outputs the third signal in order to effectively adjust differences between color gamuts of different devices. In the conversion processing, a conversion function for directly converting the first color signal into the third color signal is obtained by synthesizing three functions, namely, a first conversion function for converting the first color signal into a standard color space signal, a second conversion function for converting the standard color space signal into the third color signal, and a third conversion signal for converting the standard color space signal into another standard color signal suitable for a color gamut of the printer. The first color signal is converted into the third color signal in accordance with the new synthesized conversion function.

摘要： A PDL interpreter rasterizes image data, which are described in page description language, entered from a host computer, and stores the rasterized image data in an image memory. A CPU discriminates the type of image, pixel by pixel, by referring to the image data stored in the image memory, and stores a discrimination code, which indicates the result of discrimination, in a code memory. The CPU reads out image data that have been stored in the image memory and reads the discrimination code corresponding to these image data out of the code memory. The image data read out of the image memory are subjected to different binarizing processing by two binarizing circuits. Depending upon the discrimination code read out of the code memory, a selector selects the output of one of the two binarizing circuits and sends the selected image data to a printer. Accordingly, it is possible to obtain a high-quality image which is a mixture of images having different characteristics, such as an image containing character or line drawings, continuous grayscale images, etc.
