Abstract: 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.

Abstract: 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.

Abstract: A non-transitory computer-readable medium stores an association program causing a computer to function as: an extracting unit that extracts a person, a container, and a product from an image captured by a camera; a first specification unit that specifies a movement of the product being transferred into or from the container; and an association unit that associates a person who has a predetermined relationship with the container into or from which the product is transferred in a case where the first specification unit specifies the movement of the product being transferred into or from the container.

Abstract: An image processing apparatus includes a separation section, a background color setting section, and a generating section. The separation section separates at least one image component having different attributes contained in electronic document data expressing an original image. The background color setting section selects a coloring method, from among a plurality of coloring methods for coloring a background, according to software to be used and sets a background color. The generating section generates software data corresponding to the software by coloring the background color based on the setting of the background color setting section, and re-arranging the at least one image component.

Abstract: 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.

When a printed document is read by a reading device and output of the document on the basis of read document information is instructed, the acquisition unit acquires at least one of attribute information of a document receiver, attribute information of an output instructor, and second identification information inputted by the output instructor. If it is determined, on the basis of a first identification information and the acquired information, that an output of a constituent element specified as an object of output restriction is not permitted, the controller restricts the output of the constituent element which is the object of output restriction in the document.
