Digitally printed anti-copy document and processes and products therefor
The present invention relates to a method and product resulting from application distortion security images in an anti-copy document, printed on demand, which may be variable and use laser printers or printer/copiers and/or ink-jet printers and/or digital presses.
Image processing apparatus, method, and recording medium storing image processing program for gradation correction to minimize the difference between the corrected colorimetric value and a colorimetric measured color value
An image processing apparatus, an image processing method, and an image processing program stored in a recording medium are provided. The image processing apparatus includes a processing circuitry, and the processing circuitry and the image processing method obtain a color image output from an image forming unit, predict an output color of the image forming unit to generate a predicted color specification value independent from the image forming unit, extract from the input image data a colorimetry area for color difference determination, obtain a colorimetric value of an area of the color image that corresponds to the extracted colorimetry area, using a colorimeter, and add a colorimetric error at the colorimeter due to a color arrangement on the input image data to the predicted color specification value, to obtain a corrected colorimetric value of the area of the color image.
IMAGE READING APPARATUS AND SEMICONDUCTOR DEVICE
An image reading apparatus includes an image reading chip for reading an image. The image reading chip includes a plurality of pixel units which include a light receiving element which receives light from the image so as to perform photoelectric conversion, an analog circuit, a logic circuit, and a power source pad to which a power source voltage is supplied. The image reading chip has a shape which includes a first side and a second side shorter than the first side. A distance between the analog circuit and a median point of the first side is shorter than a distance between the logic circuit and the median point of the first side, and a distance between the analog circuit and the power source pad is shorter than a distance between the logic circuit and the power source pad.
Automatic detection of corners of an imaged document
A method includes obtaining an image of a document against a background. A bounding box that bounds a region of the image that is distinguishable from the background is found. Coordinates of a plurality of points of the distinguishable region are found, each point being a point of the distinguishable region that is closest to each corner of the bounding box. The document is identified within the image as a region of the image whose corners are defined by the found coordinates.
Device, system and method for identifying sections of documents
A method for identifying sections of contracts. This method works well with documents that originated from scanned images, i.e., documents that could possibly include noise and misleading cues.

Method of using address book of image forming apparatus on web browser and image forming apparatus for performing the same
A method of using an address book of an image forming apparatus on a web browser includes receiving web data in an image forming apparatus from a web server; displaying a web page corresponding to the received web data on a display unit of the image forming apparatus; receiving an input of selecting one of at least one input box comprised in the web page; analyzing a form tag corresponding to the selected input box from the web data; and displaying a virtual text input device or an address list on the display unit based on the analysis result in which the selected input box is determined as an input box for receiving an input of an email address or a phone number, wherein the virtual keyboard is capable of being synchronized with an address book of the image forming apparatus.
Image processing apparatus method and medium correcting value of pixel of interest in image data using determined amount of correction
For preferably reducing show-through in an image obtained by reading an original, an image processing apparatus: stores an index value for each of a plurality of mutually differing degrees of variation; obtains a degree of variation of signal values included in a region of interest of a predetermined size including a pixel of interest included in image data corresponding to the read image; obtains a value indicating a brightness of the region of interest; determines an amount of correction of a value of the pixel of interest using the obtained value and an index value corresponding to the obtained degree of variation; and corrects the value of the pixel of interest using the determined amount of correction.
Filter configuration for software based image path
A method, non-transitory computer readable medium and apparatus for generating an output image are disclosed. For example, the method includes receiving an image, applying a first filter, applying a second filter, calculating a difference between the image with the second filter that was applied and the image with the first filter that was applied and transmitting the difference to a sharpening module and a segmentation module to generate the output image.
IMAGE FORMING APPARATUS, CONTROL METHOD THEREOF, STORAGE MEDIUM, AND CARTRIDGE
This image forming apparatus determines, in accordance with state information indicating the state of the image forming apparatus, whether or not a timing for executing an authentication process of a removable cartridge has arrived. Furthermore, if the timing for executing a cartridge authentication process has arrived, this image forming apparatus obtains authentication information regarding authentication from the cartridge, and determines, from the authentication information, whether or not an authentication process is required to be executed. When an authentication process has been executed, an authentication result is written in a storage area of the cartridge.
