  • Unit for and method of calculating a sharpened edge
    Publication number: 20060164555

The edge enhancement unit (100) comprises: an edge determining unit (104) for determining properties of the transient (112) on basis of values of a first number of pixels around the original edge; and a filter unit (102) for calculating the sharpened edge on basis of values of a second number of pixels around the original edge and the properties of the transient (112).
