Abstract :
We have developed a new TV system equipped with a digital filter which expands a given 4:3 image vertically at the rate of 2/3 to fit into a 16:9 wide monitor leading to a pleasing visual quality. The algorithm for enlarging an image vertically can be classified in two categories: deflection and digital signal processing. The digital signal processing scheme is employed to overcome the shortcomings introduced by the deflection scheme, and it maintains the resolution of the image with a good quality
