|20140367468||METHOD AND SYSTEM FOR RECORDING IMAGES OF SURFACES OF MOVING OBJECTS WITH REDUCED DISTORTION - A method of capturing an image on a surface of an object by line sensor(s), wherein consecutive line images are taken from a plurality of surfaces or surface portions having a different inclination to a given reference plane with a predetermined frequency during a relative movement of the object with regard to the line sensor(s) and a two-dimensional first image of the surfaces or surface portions is formed from these line images, includes resampling the two-dimensional first image so as to reduce the surface resolution of an image or of images of one or more surfaces or surface portions with regard to a direction oblique to the direction of the lines corresponding to consecutive line images taken by a line sensor in such a way that differences in the surface resolution of images of surfaces or surface portions with different inclination to the reference plane are reduced or eliminated.||12-18-2014|
|20140029796||METHOD FOR THE OPTICAL IDENTIFICATION OF OBJECTS IN MOTION - The method includes the steps of acquiring, by at least one camera having a predetermined magnification ratio, at least one image containing at least one coded information and at least one object and properly associating the coded information with the at least one object on the basis of the position of the coded information and of the at least one object along an advancing direction with respect to a fixed reference system. The above-mentioned position of the coded information is determined starting from the position of the coded information within the image acquired by the camera and on the basis of the distance of the coded information from the camera. Such a distance is in turn determined on the basis of the magnification factor of a reference physical dimension detected at a surface of the object or of the coded information.||01-30-2014|
|20130341495||METHOD AND DEVICE FOR DETECTING AN OBJECT WITH BACKGROUND SUPPRESSION - A background suppression device includes emitting means emitting a light beam emitted in a set direction and optoelectronic receiving means of a light beam reflected by an object providing a first and a second signal, and processing means which, in the detecting condition of the device, receives the first and second signal and provides an output information signal, in function of the first and second signal, indicating the presence or the absence of the object within an interval of set distances. The processing means stores, in a calibrating condition, the first and second signal and provides the output information signal in function of the first and/or of the second signal in the detecting condition and of the first and/or second signal in the calibrating condition. In the calibrating condition the object is absent and accordingly the first and second signal in the calibrating condition store the background.||12-26-2013|
|20130307977||METHOD FOR IMAGE ACQUISITION - A method for image acquisition of an object in transit on a movable supporting surface includes detecting a presence signal of the object in a preset position, and at least one dimension and/or position signals, the signals being generated by at least one sensor arranged upstream of a linear camera; detecting a “trigger event” signal, generated on the basis of the presence signal, the linear camera starting to acquire an image on the basis of the “trigger event” signal; starting to acquire an image of the object, when the object has travelled a preset distance from the preset position, the distance being calculated by an advance sensor suitable for generating a signal comprising an electric pulse at each preset movement of the movable supporting surface; and setting a mode for image acquisition of the linear camera on the basis of a resolution of the advance sensor.||11-21-2013|
|20130256410||METHOD FOR DECODING A TWO-DIMENSIONAL OPTICAL CODE - A method for decoding a two-dimensional optical code formed by a set number of codewords, wherein decoding the code based on a single acquired image has not been successful, includes analysing an acquired image and at least one further acquired image and obtaining a respective set and further set of values of identified codewords. Each codeword can take on either an undefined value or vice versa a numeric value if the codeword is recognised. A combined set of codewords is created and each codeword of the combined set is assigned a value of a codeword of the set and/or of the further set and an algorithm for detecting and self-correction of errors is applied to the combined set to obtain confirmation of successful decoding of the two-dimensional code.||10-03-2013|
|20130038719||IMAGE CAPTURING DEVICE - An image capturing device includes an image forming device including a sensor defining an optical reception axis, at least one reading distance, and a region framed by the sensor on a substrate at said at least one reading distance. An illumination device includes an array of adjacent light sources defining an optical illumination axis. The light sources are individually drivable, and each light source is adapted to illuminate an area of a size much smaller than the size of said region framed by the sensor. The illumination axis does not coincide with the reception axis. A driver of the light sources is adapted to drive the light sources so as to switch off at least the light sources that illuminate outside of the boundary of the region framed by the sensor on the substrate at said at least one reading distance.||02-14-2013|
|20120286146||METHOD AND APPARATUS FOR GENERATING A SYNCHRONIZATION SIGNAL IN A SCANNING SYSTEM - A scanning system includes a synchronizing arrangement including a light guide and a photosensor. The light guide directs a light beam to a photosensor, wherein light is deflected by one or more moving elements in the scanning system into a scanning region. The light guide has a light entry region, a reflecting region for reflecting light entering the light entry region and one or more light exit faces, so that light entering the light guide through the light entry region is at least partly reflected in the reflecting region and exits through one of the exit faces. The shape and the properties of the light guide are such that for two pencils of light rays, a first pencil of light rays is spaced from the second pencil and is non-overlapping with said second pencil of light rays.||11-15-2012|
|20120286043||PORTABLE DEVICE AND METHOD FOR READING CODED INFORMATION - A portable device includes coded information reading means, digital image acquisition means and an illuminator, associated with the acquisition means for acquiring images. The illuminator is powerable by a driving signal which corresponds to a first current signal in a first operating mode for illuminating an image to be acquired and is powerable by the driving signal which corresponds to a second current signal in a second operating mode for emitting a visual indication indicating the outcome of the reading of the coded information, read by coded information reading means. The illuminator, which acts as a flash to acquire an image in the first operating mode, thus also acts as a visual indication of the reading outcome in the second operating mode and illuminates with a continuous or intermittent light the space in front of the illuminator to indicate to an operator that the coded information has been read.||11-15-2012|
|20120256001||METHOD FOR DECODING A LINEAR BAR CODE - A barcode decoding method includes obtaining a plurality of scanning lines defining a second set of scanning lines which also comprises a predetermined scanning line. Each scanning line has a first set of pixels, each identified by a first and by a second index. The pixels that are part of the second set of scanning lines define a third set of pixels and, from the pixels of the third set of pixels, it is possible to select a fourth set of pixels to construct an oversampled profile of the barcode, ordering intensity values calculated from the intensity values of the pixels of the fourth set. The pixels of the fourth set include pixels of the predetermined scanning line and further pixels of the third set that do not belong to the predetermined scanning line, to obtain a subpixel resolution that is able to decode the barcode.||10-11-2012|
