Abstract: Disclosed is an image reading apparatus in which the band width for reading by one scanning is variable in accordance with the original size, the reading mode, etc. R, G, and B image data of the k-th band is successively read in one-band width to store image data R1, G1, and B1 of pixel coordinates X(n, m). Then, the original is fed so as to cause partial overlapping of the (k+1)-th band with a lower predetermined pixel region of the k-th band, and R, G, and B image data of the (k+1)-th band is read in one-band width to successively store image data R2, G2, and B2 of pixel coordinates X(n, m?). The image data obtained through overlap reading of the k-th band and the (k+1)-th band is averaged to calculate correction image data, which is transferred to a host computer along with along other image data which has not been averaged as read image data. And, it is possible to optimize reading time according to the kind of original, reading mode, etc., without involving a deterioration in image quality.

Abstract: The invention provides an image reading apparatus for performing high-precision image read by canceling out noise based on digital signal processing and superimposed on an effective portion of an analog signal. The image reading apparatus superimposes digital-based data and data-clock-based fixed noise on an sensor output signal in reference data acquiring operation as well to output data with the fixed data being canceled out in image read-operation.

Abstract: In an image processing apparatus, after a current band of an image has been read, an original is fed at a distance of the upper half band width of the current band. When the next band is read, the current band at the lower half band width is overlappingly read. The band data at the lower half band width of the current band is stored in a memory, and the next band is read. Averaging processing or function processing is applied to the band data which has been overlappingly read.

Abstract: In reading an original by mounting reading means (scanner unit) on a recording apparatus, the advancing width of the original is so reduced that the reading bands k, k+l, . . . , are partially overlapped. For example in the color image reading, in generating the data of the (k+1)-th band, the data of a range overlapped with the k-th band are corrected by the data of the k-th band (for example by simple averaging), thereby achieving image reading without bandwise density fluctuation regardless of the reading mode and the original size.

Abstract: An purchase data acquiring/utilizing system of open system which collects commodity purchase information of each customer so that the desired analysis result and counting result based on the information can be easily and promptly acquired and utilized by the point-of-sale retailer or the like. A server system receives and stores purchase data on a commodity and a purchase header for identifying the attributes with respect to the purchase data, via a communication network from a client system installed at the point-of-sale retailer or on the customer side. A desired kind of analysis is performed based on the detailed data of the attributes saved in advance, and the data thus received and stored. A corresponding order identifier is generated for each analysis result.

Abstract: The present invention prevents the interference of vehicles traveling on-coming to each other when a plurality of vehicles are traveling on-coming to each other on a traveling path with a predetermined road width without increase in cost caused by setting a wide course width and without a drop in work efficiency caused by decreasing velocity. If one of the vehicles detects the other vehicle by its obstacle detection means when the vehicles are traveling on-coming to each other, the vehicle which detects the other vehicle begins deceleration to stop itself. At the same time, this vehicle transmits a deceleration control command for stopping the other vehicle to the other vehicle via transmission/reception means, therefore the other vehicle starts deceleration even if this vehicle cannot detect an obstacle.

Abstract: This invention is a vehicle monitor for avoiding interference between vehicles, etc., without incurring cost increases for deploying auxiliary equipment at a wide-area site, while imposing only low loads on communication lines and monitoring stations, without impairing safety, and while realizing high flexibility for modifications of planned travelling paths. This system can also cope with various forms of interference which can occur throughout the entire planned travelling paths. In the system of the present invention, transceiver devices are provided in the monitoring station and in a plurality of vehicles, respectively, for sending and receiving position data and directive data between the monitoring station and the plurality of vehicles, using a communication system wherewith radio-communication is possible over the distances between the monitoring station and the plurality of vehicles.
