Measuring and assessing picture quality have so far been a time-consuming chore for laboratory engineers having access to expensive and complicated electro-optical measuring equipments. The means described enables an unknown test object to be measured with respect to objective and subjective picture quality using for example a series of previously measured paper pictures in a simple and reliable way.
