    Abstract: An image reading apparatus includes a document setting table, an image data generation unit, a downsized image data generation unit, a document information generation unit, and an image cropping unit. The image data generation unit reads a plurality of source documents placed on the document setting table and generates image data representing the plurality of source documents. The downsized image data generation unit generates downsized image data by reducing a size of the image data. The document information generation unit analyzes the downsized image data to detect respective positions of the plurality of source documents and generate document information indicating the detected positions. The image cropping unit cuts out a plurality of regions from the image data according to the document information and acquires a plurality of items of cropped image data respectively representing the plurality of source documents.

    Abstract: An image processing apparatus includes an area extracting unit, a specific halftone dot area detecting unit, and an encoding unit. The area extracting unit extracts a halftone dot area from an image. The specific halftone dot area detecting unit detects a specific halftone dot area, the specific halftone dot area being the extracted halftone dot area that includes a character and of which a variation range in a distribution of luminance and hue is less than a predetermined range. The encoding unit encodes the specific halftone dot area in an encoding manner different from an encoding manner for the halftone dot area other than the specific halftone dot area, the encoding manner for the specific halftone dot area providing higher image quality after encoding than image quality provided by the encoding manner for the halftone dot area other than the specific halftone dot area.

    Abstract: An image forming apparatus includes an image scanning device, a printing device, an output tray, and a controller. The image scanning device scans a document image sheet by sheet from a document including plural sheets. The output tray is as an output destination of both the document outputted from the image scanning device and a print sheet outputted from the printing device. The controller is configured to perform a copy operation and causes the printing device to print an image based on the document image in the copy operation. Further, the printing device includes an outlet of the print sheet; and the image scanning device includes an outlet of the document, the outlet of the document outputting the document such that edges of the document and the print sheet in a width direction of the output tray are arranged at positions different from each other.

    Abstract: An image processing apparatus includes a visible code area searching unit and a color replacement processing unit. The visible code area searching unit searches for a visible code area in a color document image corresponding to a document, and the visible code area includes a visible code. The color replacement processing unit (a) generates as a local color histogram a color histogram of the visible code area in a predetermined color space and determines whether removal of a stain image should be performed or not on the basis of a ratio of a pixel classified into a bin that includes a color of the stain image in the local color histogram, and (b) replaces the color of the stain image in the visible code area with a background color of the document if it is determined that the removal of the stain image should be performed.

    Abstract: In an image forming apparatus, an extraction processing portion extracts one or more items of personal information from image data of a card read by an image reading portion. A document data acquiring portion acquires image data of a fixed-form document. A document layout acquiring portion acquires document layout information that indicates one or more composite positions in the image data of the fixed-form document where the one or more items of personal information are to be combined. A composition processing portion generates composite image data by combining the personal information extracted by the extraction processing portion with the image data of the fixed-form document in accordance with the document layout information. A print control portion causes an image forming portion to execute a composite image printing process of printing a composite image represented by the composite image data on a sheet.
