Abstract: An image reading apparatus includes a sensor, a light source, and an image-capture controller. The sensor has a sensitivity area that is in a predetermined wavelength band, and acquires an image signal in accordance with light from sheet. The light source has a first light emitting unit that emits first light having a wavelength within the sensitivity area of the sensor, and a second light emitting unit that emits second light that has a wavelength which is outside of the sensitivity area of the sensor and that excites a fluorophore applied on the sheet. The image-capture controller irradiates the sheet with the first light and the second light to acquire a first image signal using the sensor, and irradiates, after acquiring the first image signal, the sheet with only the second light to acquire a second image signal using the sensor.

Abstract: A sheet processing machine transmits information indicating a degree of contamination or damage for each sheet detected by a discrimination unit to a teller PC as a discrimination result. The teller PC saves the discrimination result received from the sheet processing machine in a data storage unit. A CPU of the teller PC decides reference levels that can attain good bill ratio designated by the user for respective items required to discriminate good/bad states of a sheet based on the previous discrimination results saved in the data storage unit. The CPU of the teller PC sets the reference levels that can attain the good bill ratio designated by the user in the discrimination unit of the sheet processing machine. The discrimination unit set with such reference levels discriminates good/bad states of sheets based on the reference levels set by the teller PC.

Abstract: Apparatus and method for identifying the color image of an object. The object's image is digitized and a cut-off portion of the image containing the object is determined. The cut-off portion image data is normalized. Selected pixels of the normalized image are subjected to an averaging process to provide an averaged image containing R, G, and B color components. H, V, and C components of the averaged image data are computed, and their V, c, and d components are computed from the H, V, and C components. A color feature extractor computes from the c and d component data a parameter representative of the object to be identified. This parameter is provided to a memory controller to retrieve from a memory that stores target images one or more images categorized according to the computed parameter. A matching section matches each retrieved target image with the Vcd component data and determines which target image is most similar.

Abstract: An apparatus is capable of reading a character or graphics image on a document at a plurality of reading linear densities. An illuminating device for illuminating the document, a focusing device for focusing the light beam reflected by the document, and a CCD reading sensor for converting the focused light beam into an electric image signal, are integrally assembled together to constitute a carriage device. This carriage device is shifted in a desirable shifting which is determined on the basis of the reading sensitivity of the CCD reading sensor and which corresponds to the linear reading density. The rotation speed of a driving device used for driving the carriage device is reduced to a desirable value by means of a transmission, the conversion ratio of which is determined on the basis of the least common multiple (LCM) of a plurality of reading linear densities. The driving pulses which should be supplied to the driving device can be easily calculated by use of the product of the "reference pulse " .phi.
