22/02/25Amakhamera e-Monochrome athwebula kuphela amandla okukhanya ku-greyscale, kuyilapho amakhamera anombala ekwazi ukuthatha izithombe ezinemibala, ngendlela yolwazi Olubomvu, Oluluhlaza Oluhlaza Oluluhlaza (RGB) kwiphikseli ngayinye. Nakuba ukuthola ulwazi lombala olwengeziwe kungabaluleka, amakhamera e-monochrome azwela kakhulu, anezinzuzo ekulungisweni kwemininingwane emihle.
Amakhamera e-Mono akala inani lokukhanya elishaya iphikseli ngayinye, angenalo ulwazi olurekhodiwe mayelana nobude begagasi bezithombe ezithwebuliwe. Ukuze udale ikhamera yombala, igridi ehlanganisa izihlungi ezibomvu, eziluhlaza okwesibhakabhaka zifakwa phezu kwenzwa ye-monochrome, ebizwa ngokuthi igridi ye-Bayer. Lokhu kusho ukuthi iphikseli ngalinye libe selithola ukukhanya okubomvu, okuluhlaza okotshani noma okuluhlaza okwesibhakabhaka kuphela. Ukwakha isithombe sombala, lawa manani e-RGB okuqina ayahlanganiswa - lena yindlela efanayo esetshenziswa amamonitha ekhompyutha ukuze abonise imibala.
Igridi ye-Bayer iyiphethini ephindayo yezihlungi ezibomvu, eziluhlaza okwesibhakabhaka, ezinamaphikseli amabili aluhlaza kuwo wonke amaphikseli abomvu noma aluhlaza okwesibhakabhaka. Lokhu kungenxa yokuthi amaza aluhlaza anamandla emithonjeni eminingi yokukhanya, kuhlanganise nelanga.
Umbala noma i-Mono?
Kuzinhlelo zokusebenza lapho ukuzwela kubalulekile, amakhamera e-monochrome anikeza izinzuzo. Izihlungi ezidingekayo zokuthwebula imibala zisho ukuthi ama-photon alahlekile - isibonelo, amaphikseli athwebula ukukhanya okubomvu awakwazi ukuthwebula ama-photon aluhlaza ahlala kuwo. Kumakhamera we-monochrome, wonke ama-photon ayatholakala. Lokhu kunikeza ukwanda kokuzwela okuphakathi kuka-2x no-4x phezu kwamakhamera anombala, kuye ngobude begagasi besithombe. Ukwengeza, imininingwane emihle ingaba nzima ukuyixazulula ngamakhamera anemibala, njengoba amaphikseli angu-¼ kuphela angathwebula ukukhanya okuBomvu noma Okuluhlaza okwesibhakabhaka, ukulungiswa okusebenzayo kwekhamera kuncishiswa nge-factory engu-4. Ukukhanya okuluhlaza kuthwetshulwa ngo-½ wamaphikiseli, ngakho ukuzwela nokulungiswa kwehliswa nge-factor of 2.
Amakhamera anombala nokho ayakwazi ukukhiqiza izithombe ezinemibala ngokushesha okukhulu, kalula nangempumelelo kunamakhamera we-monochrome, adinga ihadiwe eyengeziwe nezithombe eziningi ukuze kutholwe ukukhiqiza isithombe sombala.
Ingabe udinga ikhamera yombala?
Uma ukuthwebula ngokukhanya okuphansi kubalulekile kuhlelo lwakho lokusebenza lokuthwebula, khona-ke ikhamera ye-monochrome ingaba inketho engcono kakhulu. Uma ulwazi lombala lubaluleke kakhulu kunokuzwela, ikhamera yombala ingase inconywe.
