摘要： A code reader may include a light source configured to illuminate a target area in which items are to be located for reading machine-readable indicia associated with the items, an image sensor configured to capture an image of the target area, an illumination drive circuit in electrical communication with the light source, and an image capture circuit. The image capture circuit may be configured to (i) enable and disable the image sensor to capture an image of the target area during the high illumination and a portion(s) of the low illumination of the target area, and (ii) read an image captured by the image sensor. The illumination drive signals may cause the illumination drive circuit to generate a high illumination drive signal to cause the light source to produce a high illumination, and generate a low illumination drive current to cause said light source to produce a low illumination.
