摘要： An image reading method and apparatus are capable of high-quality reading of a transparent original with an optimum light quantity by maintaining both a transmitting light source unit for emitting light for reading the transparent original and a reading scanner of an image reader for receiving the transmitted light at an adequate relative position to keep their optical axes in alignment during scan reading. Such alignment is achieved by providing synchronization in scanning speed by placing either one of the transmitting light source unit and the reading scanner at an arbitrary selected position, scanning the proximity of the selected position with the other, determining a light quantity distribution, determining a synchronous position from the distribution, carrying out such synchronous position detection at two or more distinct positions, and calculating the scanning speed ratio of the transmitting light source unit to the reading scanner from the result. Alternatively, alignment is achieved by carrying out similar synchronous position detection, determining the relative spacing between the base points of said transmitting light source and said reading scanner from the distances from the respective base points to the synchronous position, and matching the scan start positions of the transmitting light source unit and the reading scanner in accordance with the relative spacing.

摘要： An image scanning device for scanning an image on a document comprises a document table on which a document to be scanned is placed, a scanning unit which is installed in the document table for scanning an image on a document by projecting light from a light source onto the document in a time-sharing manner and detecting reflected light from the document, a moving unit which moves at least one of the document and the scanning unit to let them move relatively with each other, and a document type judgment unit which judges the type of the document in regard to transmission of light through the document based on a non-lighting period image signal which is outputted by the scanning unit by scanning the document for one line in a main scanning direction in a non-lighting period of the light source.

摘要： A method of verifying the authenticity of an image (1) rendered on a display screen (10) involves using a graphical representation of an authentication code (2) associated with the image. The graphical representation of the authentication code is also rendered on the display screen, while optional guide marks (3) may also be displayed. Both the image (1) and the associated authentication code (2) are read using a scanner (20), preferably a handheld linear scanner. The scanner calculates an authentication code based upon the image and compares the calculated authentication code with the authentication code read from the display.

摘要： The scanning method of the invention enables a user to scan transparencies with a duplex scanner having a moveable camera, and a mirror or light source associated with the camera on each side of the document path. The scanner, in its normal mode of operation, is a duplex reflective scanner which means the image, per side, is captured by reflecting light from a light source located on the same side of an opaque flat object as the CCD of the camera that captures the image. In order to scan transparencies, a mechanism is provided which allows an opposing camera light source to be aligned (moved at runtime) with the aperture of the camera opposite the opposing camera light source. This allows the light of the opposing camera light source to project through a transparent object while the opposite camera CCD captures an image of the transparency. The opposite camera, which captures the image, has its light source turned off while in the transparent scanning mode.
