Claim 13:
14. A system for mapping non-uniformities of an image sensor comprising image sensor elements in an image sensor area, each image sensor element having a coordinate and being configured to image a property from a test pattern, wherein the test pattern has one or more subunits,
wherein the system is configured to implement the steps of, for at least two different sets of image sensor elements imaging the same one or more subunits of the test pattern,
moving the image sensor and the one or more subunits of the test pattern relative to each other and positioning relative positions of the image sensor and the one or more subunits of the test pattern such that the at least two different sets of image sensor elements image the one or more subunits of the test pattern,
capturing an image of the one or more subunits of the test pattern by each of the at least two different sets of image sensor elements,
registering the property from the one or more subunits of the test pattern and image sensor element coordinate, and
mapping the non-uniformities between the at least two different sets of image sensor elements by storing the values of each registered property and image sensor element coordinate between the at least two different sets of image sensor elements in a look-up table, and
calibrating at least one of the at least two different sets of image sensor elements for the property based on the mapped non-uniformities between the at least two different sets of image sensor elements.
