Pixel sokubala sokubala


Yintoni uxinano lwepikseli

Iiphikseli nge-intshi nganye (i-PPI) ngumlinganiso woxinaniso lwe-pixel (isisombululo) sezixhobo kwiimeko ezahlukeneyo: ukuboniswa kweekhompyuter, iskena semifanekiso, kunye nemizwa yemifanekiso yekhamera yedijithali. I-PPI yomboniso wekhompyuter inxulumene nobungakanani besiboniso ngeesentimitha kunye nenani lilonke leepekseli kwicala elithe nkqo nelithe nkqo.

Okungakumbi kubungakanani beepikseli

Ukuba ufuna ukubala ubungakanani beepikseli zescreen sakho, kuya kufuneka wazi: ukubala ngokuthe tye kunye nokuma nkqo kweepikseli kunye nobungakanani bescreen sediagonal. Emva koko faka le fomyula, okanye usebenzise ikhalityhuleyitha yethu


pixel density formula
\( d_p = \sqrt{w^2 + h^2} \)
\( PPI = \dfrac{d_p}{d_i} \ \ \) where

\( w \) isisombululo sobubanzi kwiiphikseli
\( h \) isisombululo sokuphakama kwiiphikseli
\( d_p \) isisombululo esidibeneyo kwiiphikseli
\( d_i \) Ubungakanani bediagonal nge-intshi (eli linani elipapashiweyo njengobungakanani bomboniso)


Ukuba ufuna ukwazi nangakumbi, jonga ezi ngcebiso zeLinus zevidiyo zingezantsi.
