Claim 0:
1. A method 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, and wherein the test pattern has one or more subunits, the method comprising the steps of:
for at least two different sets of image sensor elements imaging the same one or more subunits of the test pattern,
relative moving of the image sensor and the one or more subunits of the test pattern and positioning the image sensor and the one or more subunits of the test pattern relative to each other 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,
mapping the non-uniformities between the at least two different sets of image sensor elements by storing values of each registered property and image sensor element coordinate for the one or more subunits of the test pattern 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.
