Abstract: The present disclosure describes techniques for improving image quality when a camera-based barcode-reading device is reading barcodes located on objects that are moving relative to the barcode-reading device. The techniques disclosed herein enable the image sensor in the barcode-reading device's camera to remain aimed at an object that is moving relative to the barcode-reading device while the camera is capturing an image of the object. Advantageously, the techniques disclosed herein can reduce image blur. In a barcode-reading device that includes a rolling shutter-type image sensor, the techniques disclosed herein can also reduce image distortion.
