Za njira yowerengera ya kukula kwa makina oyezera masomphenya.

Kukula kwathunthu = kukulitsa cholinga * kukula kwa digito

Kukulitsa kwa magalasi a cholinga = Kukulitsa kwa magalasi a cholinga chachikulu * Kukulitsa magalasi

Kukula kwa digito = kukula kwa polojekiti * 25.4/CCD kukula kwa diagonal

CCD chandamale kukula kwa diagonal: 1/3" ndi 6mm, 1/2" ndi 8mm, 2/3" ndi 11mm

Chitsanzo: 0.7X - 4.5X mandala okhala ndi 1/3" CCD ndi 14" monitor

Kukula kwa digito: 14 * 25.4 / 6 = 59.3X

Kukula konse: (0.7X - 4.5X) * 59.3=41.5X - 266.9X

Ndiye malinga ndi kasinthidwe pamwambapa, kukula kwathunthu kwa zida izi kumasinthidwa mosalekeza pakati pa 41.5X ndi 266.9X.
