Abstract: A recognition method and apparatus is disclosed which provides information on what type of barcode is to be recognized and the strategy to be applied in identifying and decoding the barcode. For N raster lines of a dimension "x", an array of one byte sums of dimension "x" is created. The sums are the sum of the "1" bits in the rectangular binary image input array in the N lines of the image. A new array can be generated which will have a dimension equal to the number of changes from black to white in the original "x-y" digital image. The values in this array will represent the length of each run of same color pels. These runs are then normalized according to rules of a particular barcode standard being handled.

Abstract: An image signal recording and reproducing system of this invention is arranged to record an image signal on a recording medium and to reproduce a recorded image signal from the recording medium. The system is provided with a first recording mode for recording an image signal for one picture having a first resolution on n recording tracks (n: positive integer) of the recording medium and a second recording mode for recording an image signal for one picture having a second resolution higher than the first resolution on m recording tracks (m: integer greater than n) of the recording medium. If an image signal recorded on the basis of the second recording mode is to be reproduced from the recording medium on which image signals are recorded in either one of the first and second recording modes, an arbitrary portion of an image corresponding to the image signal reproduced from the recording medium is extracted and outputted. The above-described arrangement makes it possible to reproduce image signals recorded in different recording modes irrespective of the kind of recording mode.

Abstract: The invention is concerned with a magnetic recording/playback apparatus in which a magnetic tape is paid out from a tape cassette and wound around a cylindrical rotary head cylinder, having a rotary head built therein, over a predetermined angle to record/playback signals through the rotary head, and more particularly, with a tape guide post driving mechanism, a pinch roller pressing mechanism and a tension servo mechanism. Specifically, the invention provides a tape guide post driving device which can reduce the size, weight and thickness of the apparatus by ensuring a large angle of rotation of a rotating member, which includes a tension arm, in a direct manner. Also, the invention realizes a pinch roller pressing mechanism in which a sufficient stroke can be obtained even when a cam gear is reduced in its diameter and can provide a sufficient stroke even with a small amount of rotation. Further, the invention prolongs the service life and achieves a remarkable reduction in both the number of parts used and the number of assembling steps by using a pad brake (brake member), instead of a band brake, for braking a rotating member and bringing the brake member into full contact over the former's entire surface with the member being braked.

Abstract: An external wall element of a building has a plate (17) which supports holograms (18). The holograms (18) are constructed in such a way that they concentrate light which is incident from a horizontal region of the angle of incidence onto a narrower horizontal region of the angle of reflection. Arranged behind the holograms (18) are light-guiding elements (21) which effect a vertical deflection of the incident light. It is achieved as a result of separate azimuthal deflection and vertical deflection of the light that the sunlight is always guided far into the room independently of the azimuthal angle and the angle of elevation of the sun. The light is directed against the room ceiling and reflected downwards from the latter. The room is illuminated brightly in a uniform fashion. <IMAGE>

Abstract: In a method and system for producing a compressed binarized version of image data from a document (12), the compression is performed in a direction which is perpendicular to the direction of scanning and conforms to a standard compression algorithm such as CCITT Group 4. Processing of the image data is done in parallel after the scanning of the document (12) is started but before the entire document (12) is scanned. A splitter (32) is used to divide a scan line of image data produced by an imager at the scan line into a plurality of channels, with each channel having at least one overlap area of pixels and with the overlap areas of pixels being used to avoid errors between channels. Thresholding and compression are performed by each one of the channels in parallel. The compressed data is packed into uniformly sized bytes prior to storage.
