摘要:
A color image is formed by a color printer by superposing images of a plurality of colors formed by a plurality of print units. A discrimination signal which represent character edge is received besides image data. The print positions of the print units are corrected according to image distortion detected by a sensor, and the image data are corrected according to corrected print position data. Further, the discrimination signal of character edge is corrected according to the detected image distortion. A color image is formed based on the corrected image data and the discrimination signal of character edge.

An image processing apparatus has a data conversion unit which converts RGB image data of a document to luminance component and chromaticity component, an optimization process unit which converts the distribution state of the luminance component data and chromaticity component data so as to achieve a distribution from a minimum value to a maximum value of the data within a color space, an encoding process unit which encodes data of each pixel as code data obtained by quantization at a gradient level less than the data within a range of gradient distribution based on mean value information, a memory which stores mean value information, gradient range exponent, and code data of each block obtained by the encoding process in the encoding unit, a decoding process unit which decodes code data in block units based on the mean value information and gradient range exponent stored in the memory, and reverse optimization process unit which returns the distribution state of data of the luminance component and chromaticty component decoded in the decoding process unit to a state prior to conversion in the optimization process unit.
摘要:
Image distortion is corrected in a color printer wherein print units for a plurality of colors are aligned to form a color image by superposing images formed by the print units. Images of the colors of a predetermined pattern formed by the print units are detected by a sensor. Based on the detection result, image distortion quantities and a setting error of the position of the sensor are detected. Then, the detected color shift on image forming is corrected according to the image distortion quantities and the setting error.

CPU performs correcting process for the difference in sensitivity caused by the difference in the kind of film and exposure condition by setting an amplification value of each video amplifier to which an image data on each color of G, R, and B is inputted wherein the amplification value is set so as to make a maximum value in the maximum and minimum values relative to an output of an image data on a predetermined number of picture elements as a predetermined value, and corrects the contents of each lookup table which is provided for maintaining an amplitude of image reading data on each color of R, G, and B constant so as to obtain predetermined output amplitude by the minimum value.
摘要:
When a portable terminal shoots a photo of a plurality of image processing apparatuses, a maintenance order is decided based on the respective states of a plurality of image processing apparatuses in a shooting range of the portable terminal. A tag representing the maintenance order is combined with the shot image and displayed on the portable terminal.
摘要:
An image processing apparatus having a plurality of functions includes a scroll display portion that displays a row of markers and a slider for specifying one or more markers sequentially by moving along the row, an image display portion that displays functional images for representing functions corresponding to the markers specified by the slider, a setting portion that receives setting item details for a function specified by one of the functional images selected, and an extraction portion that extracts a function having the setting item details received by the setting portion different from an initial value. The image display portion displays a functional image for a longer time when the functional image represents the function extracted by the extraction portion than when the functional image does not represent the function extracted by the extraction portion.
摘要:
A plurality of MFPs are connected to a data transfer system, and one of the MFPs functions as a representing MFP. The representing MFP monitors a connection status of the MFPs and a PC to the data transfer system. Upon detection of a change in the connection status, the representing MFP assigns the PC connected to the data transfer system after the change to each of the plurality of MFPs in an order up to a maximum number of PCs that can be connected, and has information necessary for carrying out data transfer to the PC be stored in the MFPs connected to the data transfer system in a distributed manner.
摘要:
A first terminal device indicates a file based on a first gesture on a touch panel, and upon receipt of a search instruction by a second gesture on the touch panel, transmits search information including the indicated file and user information to an image processing device. The image processing device stores the search information. A second terminal device obtains search information from the image processing device, executes a search operation using the search information, and transmits information that identifies retrieved data to the first terminal device as a search result.
摘要:
In order to prevent leakage of prescribed information (such as highly confidential information, for example) stored in a data management apparatus via a storage device external to such data management apparatus, when the data management apparatus carries out processing to back up the data stored therein to the external storage device, the data management apparatus prohibits backup of prescribed designated information.
摘要:
An MFP sequentially displays a plurality of operation screens on a display panel by switching, and receives a user operation on each operation screen. The user operation is performed for the switching or execution of a function, and the operation screens include screens customized by a user. A guidance information providing device includes: an information storage part storing switching information pieces in correspondence with the customized screens; a route generator that generates route information with reference to the stored switching information pieces, the generated route information indicating a display order of customized screens to be sequentially displayed between a current customized screen and a desired customized screen; a controller that selects, from among the stored switching information pieces, a switching information piece indicating switching from the current customized screen to a next customized screen to be displayed according to the display order indicated by the generated route information; a guidance generator that generates guidance information indicating an operation method for the user to switch the current customized screen to the next customized screen; and a communicator that outputs the generated guidance information.
