A cause identifying device includes a modifying unit and an identifying unit. The modifying unit, in a case in which an inexpedience is detected in an image formed on a print medium by conducting multiple processes, modifies processing content conducted during the image formation by modifying a processing parameter of a partial process or disabling a partial process. The identifying unit identifies a cause of the inexpedience on the basis of information obtained from an image formed on a print medium by image formation conducted after the processing content is modified.

Cause identifying device, image forming device, and non-transitory computer-readable medium

A bi-color-image-signal generating apparatus includes a reception unit and a generating unit. The reception unit receives specification of a specified color in a case of generating a bi-color image signal from a color image signal. The bi-color image signal has color components representing two colors which are an achromatic color and a chromatic color that is the specified color. The generating unit obtains an amount of each color material which is to be used to form an image having the two colors from the color image signal on the basis of a brightness of the specified color, an amount of each color material which is necessary for image formation using the specified color, and a brightness of the color image signal, and generates the bi-color image signal from the color image signal using the obtained amount of each color material.

Bi-color-image-signal generating apparatus, method, and computer program product, and image forming system, using relative brightness of two specified colors

An image processing apparatus includes: a printing unit that prints image information containing two or more colors with a plurality of color information corresponding to a plurality of specified colors; and a changing unit that changes, when a total toner amount is larger than a threshold value, at least one of the plurality of color information corresponding to one of the plurality of specified colors so that the total toner amount to be used for printing the image information is smaller than the threshold value.

Image processing apparatus, image forming apparatus, image processing method and computer readable medium for controlling toner consumption

A line width measuring device includes an acquisition unit, an extraction unit, and a generation unit. The acquisition unit that acquires a binary image that is obtained by reading a medium having a line width sample printed thereon with an image reading device, the line width sample representing output characteristics regarding a line width of an image forming device. The extraction unit that extracts a displacement amount of steps that are repeatedly generated in an image corresponding to the line width sample in the binary image by reading the medium with the image reading device in an orientation such that the line width sample has an angle &#x3b8; (0&#xb0;&#x3c;&#x3b8;&#x3c;90&#xb0;) with respect to a main scanning direction of image reading. The generation unit that generates line width information regarding a width of the line width sample by using the displacement amount extracted by the extraction unit.

An image processing apparatus includes a storage unit, a judgment unit and a conversion unit. The storage unit stores a reference color characteristic. The judgment unit judges as to whether or not a difference between an input color characteristic that is a color characteristic of input image data and the reference color characteristic is equal to or less than a predetermined threshold value. The conversion unit converts the input image data into a color characteristic that can be reproduced by an image reproducing apparatus, based on the reference color characteristic if the difference is equal to or less than the predetermined threshold value.

Image processing apparatus, image reproducing system and computer-readable medium

An image processing apparatus includes a first print information receiving unit for receiving first print information including image data and color information, a color conversion parameter generating unit that generates a color conversion parameter for converting a color signal of the image data to a color signal of a color space fixed in advance, based on the color information included in the first print information, and a second print information transmitting unit that generates second print information by adding the color conversion parameter to the first print information. Also disclosed is an image processing method.

Image processing apparatus and method, image output apparatus, image processing system, recording medium in which image processing program is stored, and recording medium in which image output program is stored

An image forming control apparatus includes: a gradation correction curve generator and a calibration data generator. The gradation correction curve generator generates a gradation correction curve based on a correspondence between an output instruction values each representing a density of an image to be formed by an image forming apparatus and actual density values each representing a density of the image formed by the image forming apparatus. The gradation correction curve represents a correspondence between predetermined standard density values and the output instruction values. When an output instruction value corresponding to a maximum standard density value is smaller than a maximum output instruction value, the calibration data generator corrects the gradation correction curve so that the output instruction value corresponding to the maximum standard density value coincides with the maximum output instruction value, and generates the calibration data based on the corrected gradation correction curve.
