Abstract: According to one embodiment, an image processing apparatus has a storage unit and a scanner to read an image from a sheet, generate image data by the reading of the image from the sheet, and store the image data in the storage unit. A control unit combines a reading-direction image indicating a reading direction of the scanner with the generated image data to produce combined image data, and then stores the combined image data in the storage unit, The control unit is configured to set a position where the reading-direction image is arranged in the combined image data and a size of the reading-direction image based on a reading resolution in the reading of the image from the sheet by the scanner and a recording resolution of the image data recorded in the storage unit.

Abstract: An image processing apparatus performs multiple image processes on target image information. The image processing apparatus has a control unit. The plurality of image processes include a first image process group including first image processes, and a second image process group including second image processes. The second image processes do not overlap with the first image processes. The control unit performs the first image processes included in the first image process group on the target image information, causes a first storage unit to store the target image information on which the first image processes included in the first image process group are performed, as first history information, performs the second image processes included in the second image process group on the target image information on which the first image processes included in the first image process group are performed, and outputs the first history information to a hardware resource.

Abstract: A first image forming section forms a monochromatic image with a first color material. A second image forming section forms a monochromatic image with a second color material different from the first color material. A color material selection section selects either the first color material or the second color material as a color material for image formation by a user. An acquisition section reads a document to acquire image data indicating the document. A mode selection section selects, by a user, either a first mode in which a first image processing is executed as an image processing on the image data acquired by the acquisition section or a second mode in which a second image processing, different from the first image processing, for increasing visibility of a color formed on a sheet regardless of a color material selected by the color material selection section, is executed.

Abstract: An information processing apparatus according to an embodiment includes an interface and a control unit. The interface receives image data including an object image transmitted from a first terminal. The control unit extracts a feature value of the object image in the image data, compares the feature value and feature values of commodities registered beforehand, calculates similarity for each of the commodities, and transmits information concerning the commodity having similarity equal to or larger than a specified value to the first terminal using an interface.

Abstract: An image forming apparatus of an embodiment includes an acquisition unit and a controller. The acquisition unit scans a sheet to acquire the color image of the sheet. The controller converts, using parameters stored in a storage unit, the color image acquired by the acquisition unit to a monochrome image with at least one specific color being darker than the other colors.

Abstract: A system and method for creating gamma correction data for a hardcopy device includes generating a data pattern, the data pattern including data representing color pixels and monochrome pixels, dithering the color pixels of the data pattern, and error diffusing the monochrome pixels of the data pattern such that the dithered color pixels and the error diffused monochrome pixels are each N-bit values, N being greater than one. A test pattern is generated based on the dithered color pixels and the error diffused monochrome pixels. The test pattern is scanned into scanned image data, and a plurality of color gamma correction curves and a monochromatic gamma correction curve are generated from the scanned image data.

Abstract: The image forming apparatus and image forming method according to the present invention have an object of outputting a latent image formed on an intermediate recording medium as a stable image when it is developed with toner on a medium such as paper or the like, to improve more the concentration of pixel values, by adding all of N pixels in N-pixel modulation and rearranging them with a screen-line position as a reference situated at the center, thereby to reduce boundaries between image portions and non-image portions in the sub-scanning direction. Specifically, to concentrate image parts of image signals of N pixels, pixel values of all consecutive pixels in the main scanning direction are added, and the pixels are rearranged with a screen-line position as a reference situated at the center, based on the addition result. If the addition result exceeds the maximum value of one pixel, the exceeding pixel is rearranged and outputted.
