Although manner and that manner which detect the amplitude variation in field of element which possesses polyvalent amplitude distribution are run includes the device and its device which are suited the video system

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 transient.
