A barcode reader can use a fast processor and a high-resolution sensor and still fail to decode a code reliably. The code may be too small in the image, blurred by motion, distorted near the edge or poorly illuminated. The lens is one of the components that determines whether the camera captures enough usable information for the decoding software.

What Is Lens Vignetting? Understanding Relative Illumination in Camera Systems
A camera image can be sharp in the center and still look noticeably weaker toward the corners. One possible reason is vignetting: a reduction in image brightness from the center toward the edge.
