Abstract
A method and apparatus for decoding codes applied to objects for use with an image sensor that includes a two dimensional field of view (FOV), the method including the steps of providing a processor programmed to perform the steps of obtaining an image of the FOV, attempting to decode a code candidate in the image using a first decode algorithm, and where the attempt to decode the code candidate fails, maintaining the image in memory. The method including repeating the above steps until one of a threshold number of attempts to decode the code candidate have failed and the code candidate has been successfully decoded. Further, the method includes accessing the images maintained in memory and attempting to decode the code candidate in at least a subset of the images stored in memory using a second decode algorithm that is different than the first decode algorithm.
