A code reader may include at least one imager configured to capture image data of a scene including a machine-readable indicia. A first circuit may be in electrical communication with the imager(s), and be configured to receive the image data from the imager. A second circuit may be in communication with the imager and the first circuit, and be configured to control operation of said imager, and to process the image data including the machine-readable indicia to decode and/or identify data represented by the machine-readable indicia. The decoded and/or identified data may be output to a computer. A third circuit may be in electrical communication with the first circuit, and be configured to process the image data to produce processed (e.g., subsampled and compressed) image data, and to output the processed image data to the computer.
