22/02/25Iikhamera ze-Monochrome zibamba kuphela ubukhulu bokukhanya kwi-greyscale, ngelixa iikhamera ezinemibala zinokuthatha imifanekiso yemibala, ngendlela yolwazi oluBomvu, oluluhlaza kunye noBuhlalu (RGB) kwipixel nganye. Ngelixa ukufumana ulwazi olongezelelweyo lombala kunokubaluleka, iikhamera ze-monochrome zinovakalelo ngakumbi, kunye neenzuzo kwisisombululo seenkcukacha ezilungileyo.
Iikhamera ze-Mono zilinganisa ubungakanani bokukhanya okubetha ipixel nganye, kungabikho lwazi lurekhodiweyo malunga nobude beefotoni ezifakiweyo. Ukudala ikhamera yombala, igridi equka izihluzi ezibomvu, eziluhlaza kunye neziluhlaza zibekwe phezu kwenzwa ye-monochrome, ebizwa ngokuba yigridi ye-Bayer. Oku kuthetha ukuba ipixel nganye emva koko ibona ukukhanya okubomvu, okuluhlaza okanye okuluhlaza okwesibhakabhaka kuphela. Ukwenza umfanekiso wombala, la maxabiso e-RGB e-intensity adityanisiwe - le yindlela efanayo esetyenziswa ngabahloli bekhompyuter ukubonisa imibala.
Igridi yeBayer yipateni ephindaphindiweyo yezihluzi ezibomvu, eziluhlaza kunye nebhlowu, ezineepikseli ezimbini eziluhlaza kuyo yonke ipixel ebomvu okanye eluhlaza. Oku kubangelwa ngamaza aluhlaza angowona anamandla kuninzi lwemithombo yokukhanya, kuquka nelanga.
Umbala okanye iMono?
Kwizicelo apho uvakalelo lubalulekile, iikhamera ze-monochrome zibonelela ngeenzuzo. Izihluzi ezifunekayo kumfanekiso wombala zithetha ukuba iifotoni zilahlekile - umzekelo, iipixels ezithatha ukukhanya okubomvu azikwazi ukuthatha iifoto eziluhlaza ezihlala kuzo. Kwiikhamera ze-monochrome, zonke iifotoni zichongiwe. Oku kunika ukwanda kovakalelo phakathi kwe-2x kunye ne-4x phezu kweekhamera zemibala, kuxhomekeke kubude befoton. Ukongeza, iinkcukacha ezintle kunokuba nzima ukusombulula ngeekhamera ezinemibala, njengoko kuphela i-¼ yeepixels inokubamba ukukhanya okuBomvu okanye okuBlue, isisombululo esisebenzayo sekhamera sincitshiswa nge-factor ye-4.
Iikhamera zemibala nangona kunjalo ziyakwazi ukuvelisa imifanekiso yemibala ngokukhawuleza, ngokulula nangokufanelekileyo kuneekhamera ze-monochrome, ezifuna i-hardware eyongezelelweyo kunye nemifanekiso emininzi ukuba ifunyenwe ukuvelisa umfanekiso wombala.
Ngaba ufuna ikhamera yombala?
Ukuba umfanekiso wokukhanya ophantsi ubalulekile kwisicelo sakho sokucinga, ke ikhamera ye-monochrome inokuba lolona khetho lungcono. Ukuba ulwazi lombala lubaluleke ngaphezu kobuntununtunu, ikhamera yombala inokucetyiswa.
