摘要:
A media for restricting the copying of a color-reversal document utilizing one or more microdots that are embedded in the color-reversal document for providing a non-visual, but machine detectable signal. By detecting the presence of one or more microdots in the color-reversal document, a copy machine is controllably prevented from copying the color-reversal document.
摘要:
A reproduction apparatus (14) for reproducing documents (12) which comprise a base material. The apparatus comprises a platen (10) for forming a scanning area and for positioning the documents (12) on its one side, scanning means (18) for scanning the scanning area, and means for obtaining a relative movement between the scanning means and the documents in order to allow for the scanning. The scanning means (18) comprise a microwave system which is constituted by microwave transceivers (26) arranged in an array such that they can detect the presence of particles (13) which have electromagnetic properties which are substantially different from the electromagnetic properties of the base material and which are incorporated in at least a part of the documents (12), irrespective of the position of the documents (12) on the scanning area.
摘要:
There is disclosed an apparatus for image reading or processing, that can precisely identify the pattern of a particularly pattern, such as of banknotes or securities of which faithful copying is to be prohibited. The apparatus is provided with a detecting unit for detecting the positional information of the original image, and a discriminating unit for extracting the pattern data of a certain part of the original image and discriminating whether the original image is the predetermined image, based on the similarly between the pattern data and a predetermined pattern.
摘要:
It is an object to properly determine a specified original supposed not to be copied. There is provided a copying apparatus wherein a pattern formed by infrared reflected light is detected, and it is determined that the original is a specified original in accordance with the pattern detected by a detecting unit, thereby determining the specified original supposed not to be copied and controlling a copying operation.
摘要:
An image reading apparatus includes, as an arrangement for discriminating a specific image with high precision, first illumination means (206) for illuminating an object image so as to perform a normal reading operation, second illumination means (205) for illuminating the object image with light having characteristics different from those of the first illumination means so as to discriminate whether or not the object image is a specific image, and means (4301, 4302, 417) for adjusting the quantity of light emitted from each of the first and second illumination means.
摘要:
Disclosed is an image processing apparatus for processing an input image and recording the image on a recording medium, and particularly a color copying apparatus which permits color copying of an original, and makes it possible to discriminate a specific original for the sake of prevention of forgery of a banknote, a negotiable instrument, or the like. The specific original is provided with copying processing which is different from that provided for an ordinary original.
