Method of detecting an amplitude transient in a field of elements having a multivalent amplitude distribution, device suitable for performing the method, and video system including the device

摘要

For the detection of an amplitude transient in a field of elements having a multivalent amplitude distribution by comparison of amplitude values of neighbouring elements, the amplitude transient is further localised by calculating an interpolation point as a function of amplitude values around the detected amplitude transient, said interpolation point being indicative of the location of the amplitude.
