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:
There is provided an image scanning apparatus including: a scanning section which scans an object opposite to a linear scanning area along a main scanning direction while moving the scanning area along a subscanning direction intersecting the main scanning direction and which generates image data on the basis of the result of the scanning; a control unit that controls the scanning section; and a pattern area including a predetermined pattern that defines a base position for specifying a position to be scanned by the scanning section, the predetermined pattern having a characteristic part that specifies a rough position of the predetermined pattern along the subscanning direction. The control unit includes: a first image acquiring section that acquires first image data by making the scanning section execute scanning at a first subscanning resolution; a pattern searching section that searches the first image data for the image of the predetermined pattern; a second image acquiring section that acquires second image data in such a manner that when the image of the predetermined pattern is not detected by the pattern searching section, the second image acquiring section makes the scanning section execute scanning at a preset second subscanning resolution lower than the first subscanning resolution so that image data generated by the scanning of the pattern area at the second subscanning resolution allows the image of the characteristic part to be detected therefrom; a characteristic-part searching section that searches the second image data for the image of the characteristic part; and a reprocessing instructing section which specifies the rough position of the pattern area along the subscanning direction on the basis of the position of the image of the characteristic part detected by the characteristic-part searching section and which makes the first image acquiring section execute scanning again at the rough position of the pattern area.
Abstract:
An image scanning apparatus includes an illuminator to radiate light on an original image; an image sensor to scan image information of the original image from the light reflected from the original image, an image processor to perform image processing with respect to a signal scanned by the image sensor, and a memory to store data which is to be image-processed. The image sensor, the image processor, and the memory may also be disposed on one circuit board in the image scanning apparatus.
Abstract:
In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.
Abstract:
An image reading apparatus includes: a light source; an image capturing device, opposed to the light source through a document table adapted to support a document and operable to receive light emitted from the light source; a detector, operable to detect a light-reception state of the image capturing device when an instruction for reading the document is given; and a corrector, operable to correct a relative position in a sub scanning direction between the light source and the image capturing device based on a detection result of the detector.
Abstract:
According to a precision assembly technique, a first subassembly is precisely aligned relative to a plurality of alignment features in an alignment fixture and at least three non-coplanar flexures having complementary alignment features are located with respect to corresponding alignment features on the alignment fixture and mechanically attached to the first subassembly. The first subassembly with the attached flexure sheets is removed from the alignment fixture and located with respect to a second subassembly having a plurality of alignment features identical to the alignment features in the alignment fixture using the alignment features on the second subassembly and the complementary alignment features on the flexure sheets to precisely align the first subassembly with the complementary alignment features on the second subassembly. The flexure sheets are then mechanically attached to the second subassembly, whereby the first and second subassemblies are aligned and rigidly connected to one another.
