Abstract:
An image processing apparatus includes a calculation unit configured to calculate an amount of a first coloring material in an area including a plurality of pixels; a determination unit configured to determine an allowable amount of a second coloring material in the area on the basis of the amount of the first coloring material, calculated by the calculation unit, and a limit of the amount of the coloring material; and a control unit configured to control an amount of the second coloring material in the area so as not to exceed the allowable amount of the second coloring material.
Abstract:
An image processing apparatus includes a calculation unit configured to calculate an amount of a first coloring material (at least one of cyan, magenta, yellow and black) in an area including a plurality of pixels; a determination unit configured to determine an allowable amount of a second coloring material, being substantially colorless and transparent, in the area on the basis of the amount of the first coloring material, calculated by the calculation unit, and a limit of the amount of the coloring material; and a control unit configured to control an amount of the second coloring material in the area so as not to exceed the allowable amount of the second coloring material.

Abstract:
When an image including a pattern expressed by a collection of dots such as a copy-forgery-inhibited pattern and a two-dimensional code is reduced simply by sampling of pixels, the dots are closely arranged to make the reduced image appear to be dark as a whole, and the content thereof becomes difficult to understand. An image processing apparatus includes a reducing unit configured to reduce an image and a deleting unit configured to delete an additional image when the image includes the additional image which has information hidden therein at the time of reducing the image by the reducing unit.
Abstract:
When color materials of more than four colors are used, a signal for the amount of toner used within a range appropriate for the apparatus and toner characteristic is generated using a color separation table. However, a printer receives print data of various formats, such as image data separated into signal values of more than four colors, or image data of a special format to which a six-color separation table cannot be applied. Hence, an image signal representing a combination of colors is input. The sum of the signal values of colors in each pixel of the image signal is calculated and compared with a limit value. When the sum exceeds the limit value, the signal values of base colors are replaced with that of a spot color based on a replacement table for replacing the signal values of the base colors with that of the spot color.
Abstract:
A destination address of transmission of designated image data attached to e-mail and a notification destination address to be notified of error information if a transmission error occurs are set. If a transmission error occurs due to size excess of the transmitted e-mail, retransmission confirmation information containing the error information and designate input accept information for accepting designate input which designates whether to execute retransmission of the e-mail in which the transmission error has occurred is generated. The generated retransmission confirmation information is notified to a notification destination specified by the set notification destination address.
Abstract:
The present invention provides an image processing apparatus that supplies image signals to an image forming apparatus that forms an image on a recording medium using recording material. The apparatus includes a storage unit that stores a limiting value of a sum of signal levels of image signals output to the image forming apparatus, an input unit that inputs C, M, Y and K signals as image signals, a first comparison unit that compares the limiting value and the sum of the signal levels of the input C, M, Y and K signals, an under color removal unit that replaces a predetermined level of C, M and Y signals with a K signal in an under color removal process When the sum of the signal levels of the input C, M, Y and K signals exceeds the limiting value, a second comparison unit that compares the limiting value and the sum of the signal levels of the C, M, Y and K signals after undergoing the under color removal process, and where the sum after the under color removal process exceeds the limiting value, an adjustment unit that reduces the C, M and Y signals after undergoing the under color removal process at an identical rate so as to reduce the sum after the under color removal process to less than the limiting value.
Abstract:
A display apparatus displays an identification information element corresponding to an image currently displayed on a display unit in accordance with a first instruction from a user. In accordance with a second instruction from the user, the display apparatus causes a printing apparatus to perform printing based on an image data element corresponding to an identification information element selected by the user from among one or more identification information elements being displayed.
Abstract:
A combination to minimize moiré can be determined theoretically or empirically in four-color printing, but it is very difficult to find a combination to minimize moiré in printing using five or more colors. To solve this problem, image data is color-separated into image data corresponding to plural colorant. Multilevel dither processing is performed to the image data corresponding to the plural colorant. At this time, dither matrices having the same screen angle, the same screen ruling, and different threshold setting methods are applied to the respective image data corresponding to dark colorant and light colorant having the same hue and different lightness values.
