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 (S), converts the obtained vector data into a data format that can be re-used by an application (S), and registers the converted file in a file server (S). 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 (S), and the composite image can be printed (S). Even when the printed document is scanned again, a registered digital file can be easily specified.

Image processing method, system, program, program storage medium and information processing apparatus

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.

Image processing method

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.

Image processing method and image processing system

In a copying machine connected to the network, calibrations on the printers are performed as follows. When an execution of calibration is requested, the copying machine displays all identification numbers of the printers connected to the network on the operation panel of the copying machine. When the user selects a printer to be calibrated through the display, the copying machine causes the selected printer to output a specified test pattern. Then the copying machine reads the test pattern, generates a correction table and registers the generated table with the printer.

Copying machine, image processing apparatus, image processing system and image processing method

A plurality of reduced images (for the color temperature and the color rendering property) of a read image of an original are displayed. The user is asked to select a reduced image close to the color of the original from among the plurality of displayed reduced images. Each parameter of the color is determined based on the selected reduced image. By performing color processing using determined parameters, color processing in which adaptation corresponding to environment is taken into consideration is realized.

Image conversion processing method and apparatus, and recording medium

A user designates a two-sided copying mode, a reduced-scale copying mode, a vertical or horizontal binding direction, and the like from a control panel. An original image is magnification-varied at a designated reduction magnification, and the reduced image is stored in a page memory. In the case of an odd page (front surface) in a single-sided or two-sided copying mode, a &ggr; conversion circuit reads out and outputs stored image data in the normal order, thus forming images. On the other hand, in the case of an even page (back page) in the two-sided copying mode, whether the horizontal or vertical binding direction is designated is checked. If the binding direction agrees with the reversing axis direction of a paper sheet upon copying, images are read out in the normal order. When the vertical binding direction is designated, images are read out in an order opposite to the normal order, so that each page is rotated through 180&deg;. Images are copied in the designated layout.

Image forming apparatus and method

Two or more original illumination units are mounted on an image reading apparatus. In reading a patched original, an image read while being illuminated along one direction is compared with an image read while being illuminated along another direction or along two directions including the one direction and another direction. In accordance with an image data difference between the two images, image processing or illumination light amount changing is performed to erase shades to be caused by a patched portion of the original.

Image reading apparatus

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.

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.

Color image processing apparatus

An image reading apparatus measures, color by color, an average transmission-density signal based upon image information obtained from a color original through which light is transmitted, converts the measured average transmission-density signal of every color into a subject-lightness signal of every color, and effects a conversion into a reference color stimulus signal, which is indicated by the apex of a triangle substantially circumscribed by a spectrum locus of a predetermined chromaticity diagram, based upon the converted subject-lightness signal of every color.

A color image processing apparatus includes arranging means for arranging intervals between dot positions on a scanning line at which dots are formed, and shifting means for shifting the dot positions on the scanning line by a shifting amount. At least one of the intervals and the shifting amount for a first color component are different from an interval and a shifting amount of a second color component. The processing apparatus also includes control means for controlling the arranging means and the shifting means so that n (n.gtoreq.3) adjacent dot positions at which the first color component and the second color component overlap correspond to vertices of a substantially regular polygon having n vertices.

A CPU performs color space compression of an input image, and also performs masking processing associated with image formation. A plurality of images having undergone different color space compression processes are sent to a monitor via a video interface. The monitor displays a plurality of images on one screen. The user selects an image having a desired color appearance from the plurality of images displayed on the monitor. The CPU converts the color reproduction range of the input image into the color reproduction range of the selected image, and supplies the resultant data to a printer via a printer interface. With this processing, a preview function is provided for forming an image having a desired color appearance.

Image processing apparatus and method

There is provided an image processing apparatus for executing a process to an input image in accordance with the characteristics thereof, comprising: an input device to input image data; a detector to detect the characteristics of the input image; and a processor to execute first and second processes such as brightness correcting processes or color balance correcting processes for the input image data on the basis of weights corresponding to the characteristics of the input image. When the weight of the first process is large, the weight of the second process is set to a small value. As the characteristics of the input image are deviated from a predetermined condition, the processor sets the weight of the first process to a small value and sets the weight of the second process to a large value. With the apparatus, the brightness and the color balance of the input image are preferably corrected and a natural image can be output irrespective of the characteristics of the image reading apparatus.
