Dynamic Auto-Focus Control for Image-Based Barcode Decoding

Abstract

A method includes: capturing, via an image sensor of a computing device, a first image in a frame sequence using a first autofocus region having a first position; detecting a region of interest having a second position in the image, the region of interest containing a barcode; in response to receiving, at an autofocus controller, a failure to decode the region of interest, generating, by the autofocus controller, a second autofocus region based on the second position of the region of interest in the image, the second autofocus region configured for capturing a second image in the frame sequence via the image sensor.
