1. A data reader, comprising:
a first imager and a second imager configured to capture images of a scene; and
an image processing system communicatively coupled to each of the first imager and the second imager, to receive image data from each of the first imager and the second imager, wherein the image processing system is configured to:
produce a virtual frame comprising a plurality of regions, each region containing a reduced-data image frame that is based on a corresponding one of the images captured by the first imager or the second imager;
assess attributes of each of the plurality regions of the virtual frame according to first predefined criteria; and
set operational parameters for a subsequent acquisition phase of at least one of the first imager or the second imager based on a result of the assessment,
wherein, at least one of the first imager or the second imager is configured to capture additional images during the subsequent acquisition phase according to the set operational parameters.
