摘要： An image processing apparatus includes a first correction amount acquiring unit and a first correction unit. The first correction amount acquiring unit acquires a first luminance correction amount of each block based on the luminance of each pixel in the block obtained by dividing a first image among multiple processing target images obtained by imaging a target object with multiple sheets bound together while opening the target object. The first correction unit corrects the luminance of each pixel in the multiple processing target images based on the first luminance correction amount of each block acquired by the first correction amount acquiring unit.

摘要： For preferably reducing show-through in an image obtained by reading an original, an image processing apparatus: stores an index value for each of a plurality of mutually differing degrees of variation; obtains a degree of variation of signal values included in a region of interest of a predetermined size including a pixel of interest included in image data corresponding to the read image; obtains a value indicating a brightness of the region of interest; determines an amount of correction of a value of the pixel of interest using the obtained value and an index value corresponding to the obtained degree of variation; and corrects the value of the pixel of interest using the determined amount of correction.

摘要： An image reading apparatus includes a tray to place a document, a conveying mechanism for a document, a reader for a document image, a detector for detecting a sheet jam, an image processor and a controller. The image processor performs an image processing for removing document smear from an image read by the reader. The controller controls a document conveying operation by the conveying mechanism and a document reading operation by the reader. If a jammed document is removed and the document is placed again on the document tray after the detector detects a sheet jam, the controller performs a sheet jam recovery processing for causing the conveying mechanism to convey the document again and causing the reader to read the image of the document. The image processor performs the image processing on the image of the jammed document read by the reader during the sheet jam recovery processing.

摘要： In an image processing apparatus having a first reading unit to read a front-face image of an original which is conveyed and a second reading unit to read a back-face image of the original which is conveyed, image processing parameters for eliminating the back-face image which is projected as a show-through image to the front-face image of the original which is displayed to a displaying unit are input. An image process according to each of the input image processing parameters is executed to image data of the front-face. The image data displayed to the displaying unit is switched to the image-processed image data of the front-face.

摘要： A color conversion device includes an acquisition section and a correction section. The acquisition section acquires first color information of an image to be printed on a specific position in a first side of a recording paper and second color information of an image to be printed on a position corresponding to the specific position in a second side of the recording paper. The correction section corrects the first color information and second color information acquired by the acquisition section, based on combination information on color combination of images on the corresponding positions of the first side and the second side.
