Abstract: An image scan apparatus includes a scanner including: a document table on which a document is placed; a carriage which scans a read area of an image; a stepping motor which moves the carriage; an image processing unit which processes an image signal resulted from scanning by the carriage; a scanner controller which performs a process necessary to read the image; and memory which stores information, wherein on the document table, a sub-scan magnification adjustment chart which expresses a predetermined shape in order to calculate an actual sub-scan magnification by the scanner controller is placed. According to the image scan apparatus, when error occurs in the actual sub-scan magnification, the sub-scan magnification can be automatically adjusted without an operator performing the adjustment work of the magnification in the sub-scanning direction.

Abstract: An image scanning apparatus moves a copyboard provided between an original document and three line sensors and the three line sensors relatively to each other at a speed different from the speed of conveying an original document. An in-line correction portion allows three data output by three line sensors to be synchronized so that a foreign object on the copyboard appears at different positions of the original document in chromatic color. A foreign object position detection portion detects a position on the copyboard of a foreign object before an original document is conveyed, and a color determination portion decides a determination pixel for use in determination from a plurality of pixels included in each of scanned data obtained while the original document is conveyed, based on the position of the foreign object, and determines whether the original document is color or black-and-white based on the determination pixel.

Abstract: The present invention relates to a method for controlling an image scanner for reading images by moving an image sensor. Specifically, the present invention relates to a control method for detecting the boundary between a white region and a black region formed at a predetermined place in accordance with a signal output from the image sensor and determining the home position of the image sensor in accordance with the position of the boundary. Particularly, the present invention is an invention for providing a control method for preventing erroneous recognition due to influence of external light.The above objects are achieved by methods of the present invention such as a method for confirming whether, when an output signal probably showing a black region is obtained, the same detection result is obtained again at another position in the black region, a method for excluding the vicinity of a housing end subject to external light from a read range, and a method for previously generating a threshold for detecting a black region in accordance with a signal output from an image sensor to use the value of the signal.

Abstract: A movable calibration device for a sheet-fed scanner includes a calibration sheet and a cam. A scanning module scans an image on the calibration sheet for calibrating the sheet-fed scanner. The cam, driven by a motor, moves the calibration sheet into and out of a scan window of the scanning module. The calibration sheet can be moved out of the scan window without reversing the rotational direction of the motor.
