Abstract
An imaging sensor includes an imaging array with a plurality of pixels. A sub-set of the pixels are marker pixels configured to each provide a constant respective output value to embed an orientation and alignment marker in images produced with the imaging array. The marker pixels can be sparsely distributed across the imaging array.
