Abstract
Incremental magnification is used to decode optical patterns, such a barcodes, in a scene. A first image of a scene is acquired using a first magnification of a camera, wherein the first image comprises a barcode. The barcode cannot be decoded. The magnification of the camera is increased by a predetermined magnification from the first magnification to a second magnification. A second image is acquired of the scene, including the barcode. The barcode is decoded after acquiring the second image.
