Mmụba zuru oke = mmụba ebumnobi * mmụba dijitalụ
Mmụba anya lensi ebumnuche = Mmụba anya lensi ebumnuche buru ibu * Mmụba anya lensi
Mmụba dijitalụ = nha ihe nlele * 25.4/CCD nha diagonal ebumnuche
Nha diagonal nke CCD lekwasịrị anya: 1/3" bụ 6mm, 1/2" bụ 8mm, 2/3" bụ 11mm
Ihe atụ: Lensi 0.7X - 4.5X nwere 1/3" CCD na 14" monitor
Mmụba dijitalụ: 14 * 25.4 / 6 = 59.3X
Mmụba mkpokọta: (0.7X - 4.5X) * 59.3=41.5X - 266.9X
Dịka nhazi dị n'elu si dị, mmụba zuru oke nke akụrụngwa a na-agbanwe agbanwe n'etiti 41.5X na 266.9X.
