摘要： A bar code reader 10 includes a housing 20 including one or more transparent windows H, V and defining a housing interior region. As a target object is swiped or presented in relation to the transparent windows an image of the target object is captured. Cameras C1-C6 have an image capture sensor array with a global shutter is positioned within the housing interior region for capturing an image of a bar code within a camera field of view. All the cameras produce images in a sequential manner during an image frame time period. An image processing system has a processor for decoding a bar code carried by the target object. The processing system responds to signals from a light sensor to terminate object illumination when an adequate image exposure has transpired.

摘要： An automatic focusing system for an imaging-based bar code reader. The automatic focusing system employs a two step process for moving a lens of an imaging system along its path of travel such that a sharp image of a target bar code is projected or focused onto an imaging system pixel array. The first step is laser ranging which utilizes a laser beam for range finding. Laser ranging determines a distance between the imaging system pixel array and the target bar code. Given the determined distance, the automatic focusing system moves the lens to a suitable position for imaging the target bar code. If ambient conditions prevent laser ranging from properly working, the second step is focus analysis. Focus analysis involves moving the lens in accordance with a search routine and analyzing image frames of the target object to find a suitable focus position.
摘要翻译：一种用于基于成像的条码阅读器的自动对焦系统。自动对焦系统采用两步法，沿着其行进路线移动成像系统的透镜，使得目标条形码的清晰图像投影或聚焦到成像系统像素阵列上。第一步是使用激光束进行测距的激光测距。激光测距确定成像系统像素阵列与目标条形码之间的距离。给定确定的距离，自动聚焦系统将镜头移动到合适的位置，用于对目标条形码进行成像。如果环境条件阻止激光测距正常工作，第二步就是焦点分析。焦点分析涉及根据搜索程序移动镜头并分析目标对象的图像帧以找到合适的焦点位置。
