1. A display controller, comprising:
a filter stage to receive an input image layer comprising a plurality of input image pixels, and to provide a plurality of output image pixels based on the plurality of input image pixels, wherein:
each pixel of the plurality of input image pixels includes marking information indicating safety relevant or non-safety relevant;
each pixel of the plurality of output image pixels includes marking information indicating safety relevant or non-safety relevant;
a particular output image pixel of the plurality of output image pixels is based on a group of more than one of the plurality of input image pixels; and
the marking information of the particular output image pixel is set by the filter stage to indicate safety relevant in response to all of the pixels of the group being marked as safety relevant; and
a verifier stage, coupled to the filter stage, to validate the plurality of output image pixels based on the marking information of an output image pixel indicating that the output image pixel is safety relevant, and based on reference data.
