Summary
| Description |
Deutsch: Modulationsübertragungsfunktionen Modulationsübertragungsfunktionen (MTF) T eines sehr guten Objektivs bei verschiedenen Digitalzoomfaktoren (1 x, 2 x, 4 x und 8 x) unter Berücksichtigung der Kontrastempfindlichkeitsfunktion (CSF) des menschlichen Auges über der Ortsfrequenz R in Linienpaaren pro Bildhöhe (LP/BH). Ohne Digitalzoom hat das Objektiv eine Modulationsübertragung, die erheblich über den Erfordernissen eines menschlichen Betrachters liegt. Bei zweifachem Digitalzoom sind die Kontraste für den menschlichen Betrachter noch fast ohne Einschränkungen, bei vierfachem Digitalzoom gibt es bereits deutliche Einbußen, und bei achtfachem Digitalzoom sind die Kontraste erheblich reduziert.
English: Modulation transfer functions (MTF) T of a very good lens at various digital zoom factors (1 x, 2 x, 4 x and 8 x) taking into account the contrast sensitivity function (CSF) of the human eye over the spatial frequency R in line pairs per picture height (LP / BH). Without digital zoom the lens has a modulation transfer which is significantly above the requirements of a human observer. At two times digital zoom, the contrasts for the human observer are almost without restrictions, at four times digital zoom, there are already significant losses, and eight times digital zoom, the contrasts are dramatically reduced. |
