1. A bar code reading device comprising: a two-dimensional image sensor array comprising: a first subset of pixels comprising a plurality of monochrome pixels configured for use in generation of a frame of image data; and a second subset of pixels; wherein the first subset of pixels may be selectively addressed independently of the second subset of pixels by the device to read out the frame of image data, such that the device is configured to decode representations of a bar code captured in the frame of image data; and wherein at least the first subset of pixels is configured to be operated in a global shutter mode, wherein all or substantially all of at least the first subset of pixels in the image sensor array are exposed in the image sensor array in response to an exposure control timing pulse.
