An image processing apparatus includes: a gradation correction section that performs output gradation correction with respect to input multi-value image data; a conversion section that converts the multi-value image data, which is acquired after the output gradation correction is performed by the gradation correction section, into binary image data; a storage section that stores the multi-value image data or the binary image data; and a control section that performs control such that the multi-value image data, which is acquired before the output gradation correction is performed, is stored in the storage section in a case where content of the input image data is content which requires the output gradation correction, and such that the binary image data is stored in the storage section in a case where the content of the input image data is content which does not require the output gradation correction.

Image processing apparatus, image forming system, and non-transitory computer readable medium storing program

An image processing apparatus includes an extraction unit, a memory controller, and a transfer unit. The extraction unit extracts, on the basis of image information, pieces of color information having a high frequency of occurrence as color information that is necessary to perform image processing. The memory controller causes a first memory to store a color information group including the pieces of color information extracted by the extraction unit. The transfer unit transfers the color information group from the first memory to a second memory, an access time of the second memory being shorter than an access time of the first memory.

Image processing apparatus, image forming apparatus, and non-transitory computer readable medium

An image reading apparatus includes an image data obtaining unit, a foreign material position information obtaining unit, and a separation processor. The image data obtaining unit obtains image data read from a document passing over a read area. The foreign material position information obtaining unit obtains foreign material position information read from the read area in which the document is not present. The separation processor separates the image data into plural objects including a background object, detects, by using the foreign material position information, a streak image portion caused by foreign material in the read area and included in the image data, and assumes a pixel of the streak image portion to belong to the background object if the pixel is present in the background object and has a pixel value equal to or smaller than a threshold determined in accordance with a representative value of the background.

Image reading apparatus and image reading method for performing background removal processing on image data

An image reading device includes a reading unit, a first correcting unit, and a second correcting unit. The reading unit includes multiple read pixel-arrays and converts a signal charge obtained from pixels in each read pixel-array to an electric signal and outputs the electric signal as a read signal of each read pixel-array. The first correcting unit individually delays the read signals of the respective read pixel-arrays output from the reading unit so as to correct misregistration of the read signals. The second correcting unit corrects the misregistration of the read signals of the respective read pixel-arrays corrected by the first correcting unit by performing a two-point interpolation process so that a correction amount for the read signal of one specific read pixel-array among the multiple read pixel-arrays is not smaller than a correction amount for the read signal or signals of the remaining read pixel-array or pixel-arrays.

Image reading device and image forming apparatus

There is provided a document destruction apparatus including: a destruction section that destroys documents; a conveyance section that conveys documents to the destruction section a page at a time; a reading section that is disposed partway along the conveyance section and that, from a document to which identification information for identifying the document has been applied to each page at at least one of a conveyance direction leading end side and trailing end side, reads the identification information at each page; and an alteration section that, in a case in which the identification information has been read at the conveyance direction leading end side by the reading section, alters a conveyance direction of the page that has been read such that the page will be conveyed from the conveyance direction trailing end side.

Document disposal apparatus

An image processing apparatus has an extracting unit, a dividing unit and a text searching unit. The extracting unit extracts a text part from an image. The dividing unit classifies text in the text part based on color information of the text. The text searching unit searches the text based on the color information.
