    Abstract: 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.

    Abstract: An optical code reading system and method are provided for reading and decoding an optical code. The system includes a plurality of light sources, a color image sensor, a processor and a decoder. Each light source produces a unique wavelength/color of light to illuminate the optical code, such as a direct mark optical code. The image sensor detects the reflected light from the optical code and generates an integrated multi-colored image. The processor separates the integrated image into individual color channels, where each color channel includes data representative of the imaged optical code in one color. The processor analyzes the contrast for each color channel and determines which color channel has the optimum contrast. The data corresponding to the color channel having the optimum contrast is then decoded by a decoder.
