1. A method of processing an image obtained with a multi-resolution biometric sensor having a first sensing region and second sensing region, the first sensing region having a resolution lower than a resolution of the second sensing region, the method comprising: acquiring a first image of an input object, the first image including an area of the input object imaged by only the second sensing region of the multi-resolution sensor; acquiring a second image of the input object, the second image including an area of the input object imaged by both the first sensing region and the second sensing region of the multi-resolution sensor; and processing each of the first image and the second image to determine biometric information of the input object.
