Abstract: An image processing apparatus includes a region detection unit configured to detect from an image a region which is sandwiched between a pair of opposite lines and in which image formation is performed at a density lower than a predetermined density, a rendering unit configured to render a border of an inner portion inside the region sandwiched between the pair of opposite lines with a line having a density higher than the predetermined density, and an outputting unit configured to output an image in which the inner portion inside the region sandwiched between the pair of opposite lines is bordered by the border rendered by the rendering unit.

Abstract: It is very important to manage digital documents and documents obtained by printing the digital documents. After completion of a conference, each participant makes an MFP read a document image of a distributed reference. The MFP searches for a data file which matches the read document image with reference to information in a storage unit, and deletes the detected data file. If the number of pages of the read image is short, the data file cannot be detected, or the read document image shows a partial loss, the MFP generates a warning. Upon reception of a collection completion message, the MFP checks with reference to information in the storage unit if all data files associated with the conference are deleted. If a data file to be deleted still remains and that data file is printed, the MFP generates a warning.

Abstract: An image processing apparatus includes a receiving unit configured to receive a second image which forms a specified interference pattern when printed on a sheet on which a first image is printed, and a printing unit configured to print the second image received by the receiving unit on the sheet on which the first image is printed.

Abstract: This invention solves problems such as density shortage, toner scattering, and toner fog when images whose density is biased are successively printed. In order to achieve this purpose, an image processing equipment comprising an input unit which inputs a print job, an image processing unit which generates print data corresponding to the input print job and supplies the print data to an image forming unit, a detector which detects bias of the amount of toner application distribution in the print data, and a control unit which controls said image processing unit so as to rotate an output direction of the print data on the basis of a detection result of said detector.

Abstract: Upon searching for a digital document of a document image, if information indicating a security level “vector conversion of objects is NG” is embedded in the document of interest, information of objects to be used in the search is deficient, thus disturbing satisfactory search processing. To solve this problem, a document image is read, and the read image is divided in accordance with the attributes of image regions. Designation of an image region whose image is to be vector-converted of the divided image regions is accepted, and additional information included in the designated image region is extracted. Search processing of a data file corresponding to the document image is controlled in accordance with the presence/absence of the additional information or the interpretation result of the additional information.

Abstract: To detect with high accuracy a particular pattern hardly disturbing eyesight by identifying a pixel where paper fiber cannot be identified, as a particular pattern pixel on the basis of an result of an of paper fiber from a particular color pixels. An image processing apparatus according to an embodiment of the present invention includes a paper fiber identification unit configured to identify paper fiber from an original read signal, a particular color pixel identification unit configured to identify a particular color pixel from the original read signal, a particular pattern detection unit configured to identify a pixel where paper fiber cannot be identified, as a particular pattern pixel on the basis of an identification result of the paper fiber identification unit from the particular color pixel, and a control unit configured to control the image processing apparatus in accordance with a result of the particular pattern detection unit.

Abstract: An object of the present invention is to improve an image quality of a regeneration image of the identified ink jet document. The present invention includes a paper fiber detecting unit configured to detect a paper fiber for each pixel by an image signal obtained by reading a document, a print pixel identifying unit configured to identify whether or not pixels are print pixels for each pixel by the image signal, a document pixel identifying unit configured to identify whether or not the pixel is a pixel requiring a correction based upon the detection result by the paper fiber detecting unit and the identification result by the print pixel identifying unit, and an image correcting unit configured to correct the image signal in a case where it is determined that the pixel is the document pixel requiring the correction by the document pixel identifying unit.

Abstract: An image processing device corrects brightness/hue in appearance of an object of interest while suppressing an effect of an optical illusion even if the object of interest is overlapped with a background part of any color. The image processing device includes an evaluation device that evaluates a record value of the object of interest and the background part thereof, a device that corrects the record value of the object of interest in order to correct the optical illusion of a human being according to a result of evaluation by the evaluation device, and a device that performs record with the record value after the correction.

Abstract: Along with digitization of information, it has become more easy to share and use information over a broad range. It is very important to manage digital documents and documents obtained by printing the digital documents. After completion of a conference, each participant makes an MFP read a document image of a distributed reference. The MFP searches for a data file which matches the read document image with reference to information in a storage unit, and deletes the detected data file. If the number of pages of the read image is short, the data file cannot be detected, or the read document image shows a partial loss, the MFP generates a warning. Upon reception of a collection completion message, the MFP checks with reference to information in the storage unit if all data files associated with the conference are deleted. If a data file to be deleted still remains and that data file is printed, the MFP generates a warning.
