An image forming apparatus includes an imaging unit configured to form pattern images in areas corresponding to positions at which toners including a specific color toner of a specific color are provided; a reading unit configured to read the formed pattern images; a color information detection unit configured to analyze color information of the read pattern images and detect the color information of the specific color toner; a position determination unit configured to determine the position at which the specific color toner is provided from a position at which the pattern image of the specific color is formed in the read pattern images; and a recording unit configured to record the detected color information of the specific color toner and the position at which the specific color toner is provided.

Image forming apparatus, image forming method, and storage medium

An image processing apparatus is disclosed. In the image processing apparatus, when preview images and/or thumbnail images of image data of plural documents read by a scanner section are formed, a preview image and/or a thumbnail image of the image data of a document is formed before the scanner section starts to read image data of a next document, and the formed preview image and/or the formed thumbnail image is stored in a storage unit. When the preview image and/or thumbnail image is displayed, the stored preview image and/or the stored thumbnail image is displayed so that the image processing apparatus can immediately and easily display the preview image and/or the thumbnail image while maintaining the productivity of the image processing apparatus.

Image processing apparatus, image processing method, and computer-readable recording medium storing image processing program

An image processing device includes a processing part configured to process first image information so that second image information is generated; wherein the image information includes image data and reference information accompanying the image data; and the processing part correlates first reference information included in the first image information and second reference information included in the second image information, so that the first image information is processed and the second image information is generated.

Image processing device, image processing method, and information recording medium

When image data of an original document is detected to include specific information indicating outputting of the original document is prohibited, a selected color component of the image data is applied with concealing processing to make image data of the selected color component to be solid image data. The selected color component is determined based on whether outputting of the original document as a monochrome image is allowed or prohibited.

Apparatus and method of concealing information of image data

An image reading apparatus is disclosed. The image reading apparatus provides plural sensors and a correction unit that corrects displacement of image data caused by intervals among the plural sensors and includes a first draft reading mode whose scanning direction by the sensors is the same as at the time of shading correction and a second draft reading mode whose scanning direction by the sensors is different from at the time of shading correction. The correction unit includes plural paths in which a different number of delay units are disposed in each path and changing over units that change over a connection between the sensors and the paths. The changing over units are changed over between at the time of reading image data and the shading correction in the first draft reading mode and at the time of reading image data in the second draft reading mode.

Image reading apparatus, image reading method and image processing apparatus

A digital copying device, which serves as an image reading apparatus for improving processing speed by adjusting the timing of various operations when reading is performed using a sheet-through system, causes a first traveling body to move beneath a white reference plate in order to read the white reference plate, and then performs an ADF shading operation to move the first traveling body beneath a sheet-through contact glass. The sheet-through contact glass is then subjected to a dirt detection operation by reading a dirt detection reference plate, whereupon an original is conveyed onto the sheet-through contact glass by an ADF to perform a sheet-through reading operation whereby an image of the original is read. When a sheet-through reading operation is to be performed, the sheet-through reading operation is started following the reception of an image reading request and after the elapse of a time (T=Ts+Tl&#x2212;Td) obtained by subtracting a time Td, which extends from the beginning of the sheet-through reading operation to the point at which the tip of the original reaches a sheet-through reading position, from the sum of a time Ts required for the ADF shading operation and a time Tl required for the dirt detection operation.
