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.
