ABSTRACT:
The invention relates to techniques of up-scaling an input image represented by an input video signal in an image up-scaling system, especially to a method and an image up-scaling system for up-scaling an input image represented by an input video signal, the method comprising steps of receiving and processing the input video signal in an up-scaling device (21, 23), providing a linear up-scaled video signal generated by the up-scaling device (21, 23) to a signal combining device (24), receiving and processing the input video signal in a harmonics generation device (22, 25, 26, . . . , 30), generating an up-scaled output image represented by an up-scaled output video signal by combing the up-scaled video signal with a higher harmonics video output signal provided by the harmonics generation device (22, 25, 26, . . . , 30) in the signal combining device (24), and providing the up-scaled output video signal to an output of the combining device (24).
