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.

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.

This invention provides an image processing method which allows easy re-use of image information that is stored to minimize deterioration of image quality and the storage capacity. Storage means is searched for original digital data corresponding to each input image. If no original digital data is found, the input image is converted into vector data, and is stored as digital data in the storage means. A sheet including at least one of information associated with the found original digital data when the original digital data is found in the search step and information associated with digital data which is obtained by converting the image into the vector data in the vectorization step and is stored in the storage step when no original digital data is found in the search step is generated, thus providing a sheet that allows easy re-use.

It is required to protect the copyrights and the like of partial images which form respective parts of an image obtained by reading an image, exchanged using a print as a medium, by an image scanner or the like. Input image data is divided into a plurality of image regions having different features, digital watermarks, which are embedded in the detected image regions by embedding methods corresponding to the features of the image regions, are extracted, and the availability of the input image is checked on the basis of the extracted digital watermarks.

摘要:
Interpolation processing is applied to the output of a look-up table in which a correlation between color-separation signals and density signals ideal for these color-separation signals are stored, with a quantization error produced when quantizing the color-separation signals being adopted as an interpolation coefficient. The quantization and the interpolation processing are executed in a uniform color space.

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.

A color image processing system for performing undercolor removal. The system includes input of a color image signal, generation of a grayness signal from the color image signal, generation of a darkness signal from the color image signal, and performance of undercolor removal based on the grayness signal, the darkness signal, and a black signal corresponding to the color image signal. The system also includes control of an amount of undercolor removal performed on the color image signal so that a gradient of an amount of undercolor removal performed on the color image signal relative to the grayness signal at a first darkness signal level is lower than a gradient of an amount of undercolor removal performed on the color image signal relative to the grayness signal at a second darkness signal level, wherein the second darkness signal level is lower than the first darkness signal level.
