摘要:
A mobile device includes a camera, a user interface system, and a processor communicatively coupled to the camera and the user interface system. The user interface system includes a visual display. The processor is configured for (i) capturing an image including a code symbol, (ii) displaying the image on the visual display, (iii) determining whether the code symbol in the image is readable by the processor, and (iv) displaying on the visual display a positive indicator overlaying the code symbol in the image when the processor determines that the code symbol in the image is readable by the processor. The processor is further configured for reading the code symbol in the image in response to a selection input received from the user interface system.

Es wird ein optoelektronischer Sensor (10) zur Erfassung von Objekten in einem Erfassungsbereich (14) angegeben, der ein Lichtempfangselement (12) zum Erzeugen eines Empfangssignals aus Licht, das aus dem Erfassungsbereich (14) auf das Lichtempfangselement (12) fällt, eine Anzeigeeinrichtung (22a-b) zum Hervorheben der Lage des Erfassungsbereichs (14) für das menschliche Auge durch ein in den Erfassungsbereich (14) projiziertes Lichtmuster (26) sowie eine Steuer- und Auswertungseinheit (30) zum Auswerten des Empfangssignals umfasst. Dabei weist das Lichtmuster (26) mindestens zwei aus verschiedenen Quellen (22a-b, 52, 54) projizierte Teilmuster (26a-b) auf, die gemeinsam ein Zentrum (28) des Erfassungsbereichs (14) markieren, unabhängig von einem Abstand, in den das Lichtmuster (26) in den Erfassungsbereich (14) projiziert ist.
摘要:
Embodiments of the present disclosure provide code readers for reading codes provided as patterns imprinted on objects. Light interacts with a pattern by e.g. being reflected from or transmitted through the pattern, and at least some of the light that has interacted with the pattern is incident on photosensitive element(s) of one or more photodetectors of a code reader. The code reader employs centroid-measuring photodetector(s), i.e. photodetectors that detect light in such a manner that centroid of a pattern can be obtained directly from the photocurrents generated as a result of the photosensitive elements detecting light incident thereon. The code reader is then configured to process the detected light to determine a centroid of the pattern from the detected light and to decode data encoded in the pattern based on a position of the centroid. Such code readers are substantially less complex than camera-based devices and avoid mechanical scanning.

A method (10) of predicting the location of a region of interest within an image of a scannable object (13) comprising providing a scanner (12) having a processor (16) and an image sensor (22); sensing in a viewing direction toward a scannable object, with an imaging plane being perpendicular to the viewing direction; capturing an image of the scannable object with the image sensor (22); sensing motion of the scanner within a motion sensor plane relative to the scannable object (13), the motion sensor plane being parallel to the imaging plane; outputting a velocity and a movement direction corresponding to the velocity; locating a region of interest in said captured image in response to the velocity and the movement direction; and scanning the captured image beginning with the region of interest.

An image capture device for capturing an image of a test tube rack comprising a plurality of test tubes each having an individual barcode thereon, the image capture device comprising: an enclosure comprising a transparent window which, in use, is adjacent the test tube rack to be imaged; at least one camera mounted within the enclosure to capture an image through the window; a plurality of light sources mounted within the enclosure to illuminate the window and at least one light blocking element arranged to at least partially block light radiating from at least one of the plurality of light sources, wherein the plurality of light sources and the at least one light blocking element are arranged within the enclosure to provide generally uniform illumination across the whole window and to reduce unwanted reflections.
摘要:
A method and system for creating and storing an identifier for a timepiece having at least one gemstone. The method includes determining one or more characteristics of the at least one gemstone and detecting a relative position of the at least one gemstone in the timepiece. The method further includes creating the identifier for the timepiece in dependence upon at least one of the one or more characteristics of the at least one gemstone and the respective relative position of the at least one gemstone and storing the identifier in a database or device.
