(54)BAR CODE READING DEVICE WITH GLOBAL ELECTRONIC SHUTTER CONTROL


(57) The invention features an image reader (100) and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array (182), a timing module, an illumination module (104), and a control module (112). The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array (182) is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.
