Abstract: An image processing apparatus includes a processor for acquiring an input image, calculating a fluctuation range of a gradation value of a pixel within a region corresponding to a document backing in the input image, determining a threshold, based on the fluctuation range, extracting an edge pixel corresponding to a boundary between a document and the document backing from the input image using the threshold, detecting a document region from the edge pixel, and an output device for outputting an image obtained by cutting a region corresponding to the document region from the input image.

Abstract: An image processing apparatus includes a processor for acquiring an input image of a document and a periphery of the document, extracting first edge pixels from the input image, detecting a document region based on the first edge pixels, detecting a shadow region from within a predetermined range outside of the document region, extracting noise pixels in the shadow region, detecting the noise pixels, a number of which connected with one another is equal to or more than a predetermined number, as a noise line, and correcting the document region of the input image based on a detection result of the noise line.

Abstract: A scanner-equipped apparatus includes a combination of a base unit such as a printer unit, personal computer or word processor incorporating a printer unit and a scanner unit. The printer unit and the scanner unit can operate as automatic sheet feeder type apparatus, respectively. The scanner unit can be used as a handy scanner in the state detached from the base unit. The basic unit and the scanner unit are disposed substantially in upstanding posture in parallel with each other, wherein the scanner unit is removably combined with the base unit so that the scanner unit can be used as the handy scanner. A sheet transporting path for the scanner is formed between confronting surfaces of the base unit and the scanner unit. The sheet feeding mechanism for the scanner unit is so implemented as to be used intact as a driving mechanism for the handy scanner. The scanner-equipped apparatus can be realized inexpensively in a simplified mechanical structure while ensuring enhanced manipulatability.
