Abstract
A method for mapping non-uniformities of a portable image sensor having image sensor elements, each image sensor element having a coordinate. The method including the image sensor capturing images of a property from a test pattern using different image sensor elements. The non-uniformity of the image sensor can be mapped by storing the values of the property with the respective image sensor element coordinates in a look-up table.
