Ladislav Soukup He hana maʻamau ke kaua megapixel no nā kiʻi paʻi kiʻi, akā ʻaʻole i komo nui nā kelepona paʻalima. ʻO ka hapa nui o nā kelepona paʻa e noho haʻahaʻa ma ke ʻano o nā megapixels a hoʻopau ma kahi o 8 Mpix. Akā, he aha ka mea nui no nā kiʻi maikaʻi? Pono maoli ka 41 Mpix?
Nā mea ʻike
He mea koʻikoʻi ke ʻano a me ka hoʻonā ʻana o ka sensor, akā i kekahi ʻano. ʻO ka maikaʻi o ka ʻāpana optical kekahi hana nui, ʻo ia ka pilikia nui me nā kelepona paʻalima. Inā ʻaʻole kiʻekiʻe ka optics, ʻaʻole hiki i kahi hoʻonā o 100 Mpix ke hoʻopakele iā ʻoe. Ma ka ʻaoʻao ʻē aʻe, ma hope o nā optics kiʻekiʻe, hiki i kahi sensor me ka hoʻonā kiʻekiʻe ke hōʻike wale. ʻO kekahi hōʻailona koʻikoʻi ma waho aʻe o ka hoʻonā ʻana ke ʻano o ka sensor a me ke kūkulu ʻana i nā photocells pākahi.
He ʻenehana hoihoi nō hoʻi ʻIke hoʻomālamalama hope, ka mea a Apple i hoʻohana ai mai ka iPhone 4. ʻO ka pōmaikaʻi, hiki i kēia ʻano sensor ke hopu ma kahi o 90% o nā kiʻi, ma kahi o ka 60% maʻamau no kahi sensor CMOS maʻamau. Ua hoʻemi nui kēia i ke kiʻekiʻe o ka walaʻau kikohoʻe i loaʻa pinepine ʻia e nā mea ʻike CMOS. ʻO ia kahi hōʻailona koʻikoʻi o ka maikaʻi. Ma nā kūlana kukui maikaʻi ʻole, ʻike koke ʻia ka walaʻau i ke kiʻi a hiki ke hoʻohaʻahaʻa i ka maikaʻi o ke kiʻi. A ʻo ka nui o nā megapixels ma kahi liʻiliʻi liʻiliʻi (a i ʻole ka liʻiliʻi o ke kelepona ʻike), ʻoi aku ka ʻike o ka walaʻau, ʻo ia hoʻi ke kumu nui e pili mau ai nā photomobiles i ka honua i ke kaua megapixel, a paʻa ʻo Apple i 4 Mpix me ka iPhone. 5 a me ka iPhone 4S wale nō i hoʻololi i 8 Mpix, kahi i waiho ai ka iPhone 5.
E hoʻokala kākou
He mea koʻikoʻi nō hoʻi ka hiki ʻana o nā optics ke nānā aku ... i ka wā i hala (iPhone 3G) ua paʻa ka lens a ua hoʻopaʻa ʻia ka nānā ʻana ma kahi mamao kikoʻī - ʻo ka hapa nui ma ka mamao hyperfocal (ʻo ia hoʻi, ua pau ka hohonu o ke kahua ma kahi pololei. infinity a hoʻomaka kokoke i ka pahupaʻikiʻi e like me ka hiki). I kēia lā, ua hoʻololi ka hapa nui o nā kelepona kāmela i nā optics hiki ke nānā aku, ua hana ʻo Apple me ka iPhone 3GS me iOS 4.

ʻO kekahi ʻāpana koʻikoʻi ʻo ia ke kiʻi kiʻi, nāna e mālama i ka wehewehe ʻana i ka ʻikepili mai ka sensor i ke kiʻi i loaʻa.

Loaʻa i ka mea hana kiʻi ka hana o nā mea he nui - wehe i ka walaʻau (polokalamu), keʻokeʻo keʻokeʻo (i kūpono nā leo kala i ka ʻoiaʻiʻo - pili ia i ke kukui i ke kiʻi), pāʻani me ke tonality o nā kala i ke kiʻi ('ōmaʻomaʻo. a hoʻohui ʻia ka saturation uliuli no nā ʻāina, a me nā mea ʻē aʻe...), e hoʻoponopono i ka ʻokoʻa o ke kiʻi a me nā hoʻololi liʻiliʻi ʻē aʻe.
Aia kekahi mau mea naʻau i loaʻa pono kēlā 40 Mpix a hoʻohana i kahi "hoʻopunipuni" e hōʻemi i ka walaʻau ... Hoʻopili ʻia kēlā me kēia pika mai nā kiʻi kiʻi he nui (pixels ma ka sensor) a hoʻāʻo ka mea hana kiʻi e paʻi i ke kala kūpono a me ka ikaika no kēlā pika. .

Ua ʻike hou ʻia kekahi hana hoʻopunipuni ʻē aʻe (a ʻaʻole i hoʻohana ʻia i ka hoʻomaʻamaʻa me kekahi kiʻi paʻi kiʻi) - ISO pālua. ʻO ia ke ʻano o ka hapalua o ka mea ʻike e nānā me ka ʻike kiʻekiʻe a ʻo ka hapa ʻē aʻe me ka liʻiliʻi liʻiliʻi, a ua hoʻopili hou ʻia ka hopena o ka pika me ka hoʻohana ʻana i ke kaʻina hana kiʻi - ʻo kēia ʻano ka hopena maikaʻi loa o ka hoʻopau ʻana i ka walaʻau.

He hiʻohiʻona pono ka zoom, akā naʻe, ʻaʻole ia he optical ma nā kelepona paʻalima, akā maʻamau wale nō. ʻOi aku ka maikaʻi o ka zoom optical - ʻaʻohe hoʻohaʻahaʻa kiʻi. Hana ʻia ka zoom kikohoʻe e like me ke ʻoki ʻana i nā kiʻi maʻamau, ʻo ia hoʻi, ua ʻoki ʻia nā ʻaoʻao a ua hoʻonui ʻia ke kiʻi; ʻo ka pōʻino ma ka lilo o ka maikaʻi. Ke hele nei kekahi mau mea hana i ke ala o 40 Mpix sensors, kahi e maʻalahi ai ka ʻoki ʻana i nā kikohoʻe - he nui nā mea e lawe ai.
