    Abstract: Among various embodiments of the present disclosure, systems and methods for scan flow alignment are shown. A scan carriage (302) can be aligned and used in a scan flow by selecting a scan starting location (510), determining a reference mark (310) location (520), using the reference mark (310) location as a coordinate system origin (310, 530), moving the scan carriage (302) from the coordinate system origin (310) to the scan starting location (308, 312, 540), and performing a scan from the scan starting location to capture an image (550).

    Abstract: In a method of electronic recording of information from an information carrier, a position-coding pattern (3) is placed on top of or under the information carrier. The information on the information carrier and the position-coding pattern (3) are imaged with the aid of a plurality of partial images. The position-coding pattern is used to determine where the partial images should be stored in a memory area. The partial images in the memory area together constitute an image of the information on the information carrier. The position-coding pattern is filtered out of the partial images. A product, a device, and software used for implementing the method are also described.

    Abstract: An image reading apparatus includes a reading unit, a control unit, and a pattern region. The reading unit moves a linear reading range, which is provided in a main scanning direction, in a sub-scanning direction that intersects with the main scanning direction while reading an object that faces the reading range, and generates image data on the basis of a read result. The control unit controls the reading unit. The pattern region includes a predetermined pattern that defines a reference position for specifying a reading position that is read by the reading unit. The predetermined pattern has a characteristic portion that specifies a schematic position of the predetermined pattern in the sub-scanning direction. The control unit includes a first image acquisition unit, a pattern searching unit, a second image acquisition unit, a characteristic portion searching unit, a first reprocessing instruction unit, and a second reprocessing instruction unit. The first image acquisition unit instructs the reading unit to perform reading and then acquires first image data. The pattern searching unit searches an image of the predetermined pattern in the first image data. The second image acquisition unit, when an image of the predetermined pattern has not been detected by the pattern searching unit, instructs the reading unit to perform reading, and then acquires second image data. The characteristic portion searching unit searches an image of the characteristic portion in the second image data. The first reprocessing instruction unit, when the image of the characteristic portion has been detected by the characteristic portion searching unit, specifies a schematic position of the pattern region in the sub-scanning direction on the basis of a position of the detected image of the characteristic portion, and instructs the first image acquisition unit to perform reading again at the schematic position of the pattern region. The second reprocessing instruction unit, when the image of the predetermined pattern has not been detected again from first image data that are generated through second-time reading by the first image acquisition unit, instructs the second image acquisition unit to perform reading again at a position that does not include the position at which the image of the characteristic portion has been detected.
