System and method for determining when to zoom onto barcode or other optical code using imaging sensor of mobile device

Abstract

A method includes obtaining a first image frame captured using at least one imaging sensor. The method also includes determining that an optical code is contained within the first image frame and determining whether to automatically zoom onto the optical code. The method further includes, in response to determining to automatically zoom onto the optical code, identifying a zoom ratio to be applied. In addition, the method includes controlling the at least one imaging sensor to capture a second image frame that is zoomed onto the optical code using the zoom ratio. Determining whether to automatically zoom onto the optical code includes identifying a distance between the optical code and a nearest edge or a nearest corner in the first image frame and determining to automatically zoom onto the optical code based on the identified distance being greater than a threshold distance.
