Abstract
A method of determining a quality value for an image frame is disclosed. The method comprises dividing (in a step) the frame into a plurality of tiles () and determining attributes (in a step) of each said tile based upon pixel values of the tile, and pixel values of a corresponding tile of a preceding frame. The method then establishes (in steps) the quality value of the frame by testing the tile attributes of the frame against pre-determined criteria. The method then defines (in a step) the quality value of the frame depending upon results of the testing.
