22/02/25Hiki i nā kiʻi paʻi kiʻi monochrome ke kiʻi wale i ka ikaika o ka mālamalama i ka hina hina, ʻoiai hiki i nā kiʻi kala ke kiʻi i nā kiʻi kala, ma ke ʻano o ka ʻike ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli (RGB) i kēlā me kēia pika. ʻOiai ʻo ka loaʻa ʻana o ka ʻike kala ʻē aʻe hiki ke waiwai, ʻoi aku ka maʻalahi o nā kāmera monochrome, me nā mea maikaʻi i ka hoʻonā kikoʻī.
Ana nā kāmeʻa mono i ka nui o ka mālamalama e paʻi i kēlā me kēia pika, me ka ʻole o ka ʻike i hoʻopaʻa ʻia e pili ana i ka lōʻihi o ka nalu o nā kiʻi i hopu ʻia. No ka hana ʻana i kahi kāmela kala, ua kau ʻia kahi mākia me nā kānana ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli ma luna o kahi sensor monochrome, i kapa ʻia ʻo Bayer grid. ʻO ia hoʻi, ʻike ʻia kēlā me kēia pika i ke kukui ʻulaʻula, ʻōmaʻomaʻo a polū wale nō. No ka hana ʻana i kiʻi waihoʻoluʻu, ua hui pū ʻia kēia mau waiwai nui RGB - ʻo ia ke ʻano like o ka nānā ʻana i nā kamepiula e hōʻike ai i nā kala.
ʻO ka Bayer grid kahi hiʻohiʻona hou o nā kānana ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli, me ʻelua mau pika ʻōmaʻomaʻo no kēlā me kēia pika ʻulaʻula a polū paha. ʻO kēia ma muli o nā nalu ʻōmaʻomaʻo ka ikaika loa no ka hapa nui o nā kumu māmā, me ka lā.
kala a i ʻole Mono?
No nā noi i mea nui ka naʻau, hāʻawi nā kāmeʻa monochrome i nā pono. ʻO nā kānana i koi ʻia no ke kiʻi kala, ʻo ia hoʻi, ua nalowale nā kiʻi - no ka laʻana, ʻaʻole hiki i nā pika e hopu i ke kukui ʻulaʻula ke kiʻi i nā kiʻi ʻōmaʻomaʻo e pae ma luna o lākou. No nā kāmera monochrome, ʻike ʻia nā kiʻi a pau. Hāʻawi kēia i ka piʻi ʻana o ka naʻau ma waena o 2x a me 4x ma luna o nā kāmera kala, ma muli o ka lōʻihi o ka nalu o ka photon. Eia kekahi, ʻoi aku ka paʻakikī o nā kikoʻī maikaʻi e hoʻoholo me nā pahu kiʻi kala, no ka mea, hiki i ka ¼ pixels ke hopu i ke kukui ʻulaʻula a i ʻole Blue, ua hoʻemi ʻia ka hoʻonā kūpono o ka pahupaʻikiʻi ma kahi helu o 4. Ua hopu ʻia ke kukui ʻōmaʻomaʻo e ka ½ o nā pika, no laila ua hoʻemi ʻia ka naʻau a me ka hoʻonā ʻana e ka helu o 2.
Hiki nō naʻe i nā kiʻi kala ke hana i nā kiʻi kala ʻoi aku ka wikiwiki, maʻalahi a maikaʻi hoʻi ma mua o nā kiʻi paʻi kiʻi monochrome, e koi ana i nā lako lako a me nā kiʻi he nui e kiʻi ʻia e hana i kahi kiʻi kala.
Pono ʻoe i kahi pahupaʻikiʻi kala?
Inā he mea koʻikoʻi ke kiʻi haʻahaʻa haʻahaʻa i kāu noi kiʻi kiʻi, a laila ʻoi aku ka maikaʻi o ke kāmela monochrome. Inā ʻoi aku ka koʻikoʻi o ka ʻike kala ma mua o ka naʻau, hiki ke ʻōlelo ʻia kahi pahupaʻi kala.
