Abstract: A low-cost Multi Function Peripheral (MFP) prevents a user from forgetting to cancel an authenticated state. The MFP includes a scanner unit, a printer unit, a touch screen, and a reset key for initializing various settings. When the user is authenticated, the MFP accepts various operations. Under a state in which the user is authenticated, when the reset key is operated, a control unit executes a logout process.

Abstract: An image processing apparatus that determines, when performing color calibration, whether or not a calibration chart is usable. A scanning unit acquires image data by optically scanning an original document. A usability determining unit determines, in accordance with conditions for colors indicated by standard image data acquired by scanning the original document, whether or not the original document is usable as the calibration chart. A calibration unit performs, only when the determination is made that the original document is usable as the calibration chart, color calibration by using an image value at a predetermined position indicated by the standard image data.

Abstract: A method for discriminating a color of an object image. Whether unit data showing a color of a part of the object image corresponds to any position on a two-dimensional color plane is discriminated. A distribution value showing a width of a distribution range of the unit data in the color plane is acquired based on the discrimination result. Whether the object image corresponds to a full color image having mixed color expression, a specific color image not having mixed color expression or an achromatic color image is discriminated based on the distribution value.

Abstract: An image processing apparatus that reduces a color of a document image to be printed. An image generation unit scans a document to generate image data. A hue determination unit determines a specific hue included in the image data and a hue becoming a complementary color of the specific hue. A color reduction unit reduces a color of the image data based on the specific hue and the hue becoming the complementary color of the specific hue. An output unit outputs the image data whose color is reduced on a recording medium. Image data that is of a hue in a predetermined range from the hue becoming the complementary color is replaced with the hue becoming the complementary color, and image data that is outside of the predetermined range is replaced with the specific hue.

Abstract: An image processing apparatus prevents reproduction and display of an image file in a viewer of a client PC, etc., by encrypting “fileType” and “version” contained in an Image File Header (IFH), which is file format information, and “tagCount”, “sig_tag0 to 2”, “type0 to 2”, “pointer0 to 2”, and “size0 to 2”, which are file structure information, of small amounts of data, without encrypting image data (data0, data1, data2) themselves each having a large amount of data in the image file of a Tagged Image File Format (TIFF format).

Abstract: An image copying apparatus includes a target data acquiring unit, a target data saving unit, an adding unit, a sampling data saving unit, a specifying unit, a sampling data saving unit, and a correcting unit. The target data acquiring unit acquires target data from a test chart document. The adding unit adds data displaying a specification image specifying the scanning unit having scanned a test chart recorded side to the recorded side image data. The sampling data acquiring unit acquires sampling data from a copy of the test chart document. The specifying unit specifies the scanning unit having scanned the test chart recorded side from the specification image. The sampling data saving unit saves the sampling data when the scanning unit having scanned the test chart copied side matches the specified scanning unit. The correcting unit corrects the image data based on a correcting feature generated from the saved data.

Abstract: An image reader includes a first read unit, a second read unit independent of the first read unit, a determination unit, a storage unit, and a correction unit. The first read unit reads a first face of a fed document to create image data. The second read unit reads a second face of the fed document to create the image data. The determination unit determines the read unit that has read a recording face of a test chart when a test chart document, with a test chart recorded on one face, is read. The storage unit stores the read unit that has read the recording face of the test chart and sampling data extracted from image data created by the read unit that has read the recording face of the test chart in association with each other. The correction unit corrects read characteristics of the read unit associated with the sampling data, based on the sampling data.

Abstract: A digital MFP carries out an authentication of an operator by a user ID and a password prior to usage of the digital MFP. The digital MFP requests from the operator an instruction as to whether or not to store the successfully authenticated user ID and password in a flash memory along with a generated abbreviated code. When the operator instructs to store, the successfully authenticated user ID and the password are stored in the flash memory along with the generated abbreviated code. The digital MFP retrieves from the flash memory the user ID and the password that form a pair with the abbreviated code entered by the operator using the operation unit, and acquires authentication success or failure information with respect to the retrieved user ID and the password from an authentication server.

Abstract: An image processing apparatus includes an image scanner unit arranged to generate image data by scanning an original document, at least two output units arranged to output the image data scanned by the image scanner unit, a data table arranged to store a destination with respect to each output unit for at least two recipients, an output specifying unit arranged to specify, in advance with respect to each recipient, the valid output unit for the recipient to receive the image data, a recipient specifying unit arranged for the operator to specify the recipient at the time of output of the image data, and an output control unit arranged to determine a destination based on the data table, the valid output unit specified by the output specifying unit, and the recipient specified by the operator by using the recipient specifying unit, and to output the image data via the output unit that corresponds to the destination.

Abstract: An image processing device includes an accumulating unit an information deleting unit and an information updating unit. The accumulating unit accumulates image information of a plurality of pages as a multipage file, wherein the multipage file includes identification information associated with the image information of each of the pages. The information deleting unit deletes image information of any page of the multipage file. The information updating unit updates, when image information of one or more of the pages of the multipage file has been deleted by the information deleting unit, identification information corresponding to the image information of the deleted page.

Abstract: An image processing apparatus includes a color table and a black and white (monochrome) table stored in a table storage unit. Image data is inputted to a data input unit. A table processing unit replaces a density value in at least a part of the three primary colors of the color table with a density value of the black and white table, and generates a temporary table by replacing all density values in other parts of the three primary colors and black with zero. A table retaining unit temporarily retains the temporary table. A data conversion unit converts the inputted image data into print data using the temporarily-retained temporary table. A data output unit outputs the converted print data.

Abstract: A digital MFP, which offers a function called by an operator, transmits a user ID and a password acquired from the operator to an authentication server and receives an authentication result with respect to the transmitted user ID and the password from the authentication server. The digital MFP receives a permission setting, which is information associated with the successfully authenticated user ID and the password and relates to whether or not to permit to offer a function, from the authentication server, and stores the received permission setting in a RAM. The digital MFP determines whether or not to permit to offer the function after the authentication has succeeded in accordance with the permission setting stored in the RAM.
