Unit for and method of calculating a sharpened edge |
摘要 |
An edge enhancement unit ( 100 ) for calculating a sharpened edge for an original edge in an image on basis of the properties of the original edge. The original edge is represented by a transient ( 112 ) in a signal representing values of pixels of the image. 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 ).
