Noma ngabe iyiphi isizukulwane se-USB, amakhamera e-hardware ISP ahlala ephumelela kakhulu kunamamodeli e-software ISP ekusebenzeni okuphelele.
Q3: Ingabe amakhamera e-ISP wehadiwe kunzima ukuwenza ngokwezidingo ezikhethekile zezimboni?
Imininingwane eyisisekelo yokuthwebula izithombe efana nokukhanya, ukugqama, ukugcwala kombala nokucaca iyashintshwa ngokugcwele ngumsebenzisi ngamathuluzi ajwayelekile. Ukwenza ngendlela ejulile ezingeni le-algorithm kuvinjelwe ngamabomu, ukuqinisekisa ukusebenza okuzinzile, okungenaphutha esikhathini eside ezindaweni ezinzima zezimboni nokuhlangabezana nezidingo eziningi zokufakwa kochwepheshe.
