Abstract
A mobile device may include a camera assembly, a processor, memory, and a barcode-reading application. The camera assembly may include an image sensor. Pixels in a predetermined location of the image sensor may be defective pixels that provide the same output values regardless of actual characteristics of incident light. The barcode-reading application may be stored in the memory. The barcode-reading application may be executable by the processor to enable at least one enhanced mode of operation of the barcode-reading application conditional upon confirming that the image sensor comprises the defective pixels in the predetermined location.
