Abstract: A method and apparatus are described for improving the geometric fidelity of images reproduced in a charged particle beam device. The beam is deflected across a sensitive medium to form a test image of predetermined configuration. The test image is compared with a reference image and geometric deviations measured, at a number of points, are used to calculate correction signals required to modify the beam deflection to offset the deviations. Circuit adjustments are then made to provide the calculated correction signals. The correction signal adjustments are accomplished in separate non-interactive circuits for each of a plurality of predetermined corrections which only require a one time adjustment.

Abstract: This invention provides an image forming apparatus capable of preventing image omission caused by registration error correction, a control method therefor, and a program. Error amount information is acquired which is stored in a storage medium and represents the error amount of the scanning line of exposure light in the exposure scanning direction on an image carrier. The image data is modified on the basis of the acquired error amount information. A masked area for restricting the output position of an image visualized on the printing medium is modified on the basis of the modification amount of the modified image data.

Abstract: An image scanner is provided to obtain a high quality image by removing an optical interference pattern from a forgery/alteration preventing element recorded on a medium, and keep high preciseness and reliability while obtaining the high quality image by scanning both sides of the medium at the same time. A loading track guides loading of the medium(2) having the forgery/alteration preventing element generating the optical interference pattern. A loader loads the medium by being mounted along the loading track. An image sensor is mounted to obtain image data from the medium loaded along the loading track. The image sensor includes a light source(132), a light receiver(134), the first polarizer(136a) polarizing light output from the light source at a front side of the light source, the second polarizer(136b) polarizing the light reflected from the medium at the front side of the light receiver and having a phase difference of 90‹ to the first polarizer, and a lens(138) guiding the light passing the second polarizer to the light receiver.

Abstract: An illumination device includes a light guide made of plastic, and a light source including a light emitting element whose dominant wavelength is a light emission wavelength in an infrared region, and identifies a banknote. White reference plates are provided at positions that are at opposite ends of a rod lens array and cover respective areas external to an image region across the banknote. A correction coefficient is acquired by calculation. The calculation is made by correcting an illuminance such that IR correction data is substantially identical to IR reference data preliminarily stored in a memory circuit in a signal processor on the basis of IR white reference data representing a white reference illuminance generated from light reflected from the white reference plates. The correction coefficient is used for correcting IR image data when the banknote is read.
