Pixel kachulukidwe Chiwerengero
Kodi mapikiselo ndi chiyani?
Ma pixels pa inchi (PPI) ndiyeso ya kuchuluka kwa pixel (resolution) yazida zosiyanasiyana: mawonekedwe amakanema, makina ojambulira zithunzi, ndi masensa azithunzi za kamera. PPI yowonetsera makompyuta imakhudzana ndi kukula kwa chiwonetserocho mu mainchesi ndi kuchuluka kwa ma pixels m'malo opingasa ndi owongoka.

Zambiri pakulimba kwa pixel
Ngati mukufuna kuwerengera kukula kwa pixel pazenera lanu, muyenera kudziwa: kuwerengera ndi mapikiselo owerengeka komanso kukula kwazenera lanu. Kenako ikani fomuyi, kapena gwiritsani ntchito chowerengera chathu
\(
d_p = \sqrt{w^2 + h^2}
\)
\(
PPI = \dfrac{d_p}{d_i} \ \
\)
where| \( w \) | ndi kusanja m'lifupi mwa pixels |
| \( h \) | ndi kutalika kwa mapikiselo |
| \( d_p \) | ndi kusanjikiza kwa ma pixels |
| \( d_i \) | ndi kukula kokulira mu mainchesi (iyi ndi nambala yodziwitsidwa ngati kukula kwa chiwonetserochi) |
Ngati mukufuna kudziwa zochulukirapo, onani kanema wowoneka bwino wa Linus Kanema pansipa.
