Mai ka makahiki 2018, ua hoʻomaka nā kāmela kelepona i kahi "digital war" hou o nā megapixels. Ua lilo nā kāmeʻa i hoʻokahi o nā wahi kūʻai nui loa o nā smartphones a ua kau ʻia ka manaʻo nui i ka nui o nā megapixels i nā pūʻulu kelepona i kāna kāmela. Manaʻo ka hapa nui o nā megapixel ʻoi aku ka maikaʻi o ke kiʻi. Ke ala mai nei ka ninau- Pono mākou i nā kāmela megapixel kiʻekiʻe no ke kaomi ʻana i nā kiʻi ʻoi aku ka maikaʻi a me ka hoʻopaʻa wikiō?
Hoʻoholo nā megapixel kamera i ka maikaʻi o ka kamera akā ʻaʻole ia ka ʻO ke kumu wale nō a ʻo ka ʻoiaʻiʻo, ʻo ka nui o nā megapixels ʻaʻole ia he ʻoi aku ka maikaʻi o ke kiʻi. ʻO kaʻoiaʻiʻo, hoʻohana mau kekahi o nā mea hana kelepona maikaʻi loa i ka ʻoihana i kahi kāmela 12 MP, ʻoiai ʻo Apple nona ka helu megapixel haʻahaʻa loa o nā kāmela kelepona ma waho.
ʻOi aku ka paʻakikī o ka manaʻo o nā kāmera a me nā megapixels ma mua o ka mea i ʻike ʻia, e luʻu hohonu kākou i loko e hoʻomaopopo i ke koʻikoʻi o nā megapixels a pono mākou i nā kiʻi kiʻekiʻe megapixel smartphone?
He aha ka megapixel a pehea e pili ai i ka maikaʻi o ka kamera?
ʻO ka mea mua, e hoʻomaopopo kākou i ka megapixel. ʻO ka mea nui, ʻo ka Megapixel e pili ana i hoʻokahi miliona mau pika a hoʻohana pinepine ʻia e kuhikuhi i ka hoʻonā ʻana o nā kiʻi kamepiula. ʻO ka pika he huinahā liʻiliʻi ma ka nānā ʻana i ka lolouila, liʻiliʻi a hele mai ma ke ʻano o nā kiko. ʻO ke kiʻi kahi mākia paʻa o kēia mau ʻāpana a i ʻole nā kiko.
ʻOi aku ka nui o nā pika a i ʻole nā kiko i hana i ka hōʻike, ʻoi aku ka ʻoi o ka hoʻonā a i ʻole ke kiʻi. ʻOi aku ka kiʻekiʻe o ka helu o nā kiko a i ʻole nā pika, ʻoi aku ka maikaʻi o ke kiʻi, e ʻae ai i ke kiʻi kiʻi kiʻekiʻe a ʻoi aku ka ʻoiaʻiʻo. Hoʻohana ʻia ka hana maikaʻi o ke kiʻi i nā megapixels. No ka laʻana, hiki i kahi pahupaʻikiʻi 3.1-megapixel ke kiʻi i nā kiʻi ma kahi hoʻonā o 2048 x 1536 (ʻo ia ka 3,145,728 pixels). ʻO ia hoʻi, ʻo ke kiʻi hope loa he 3.1 megapixels a i ʻole 3 miliona mau kiko.
ʻOkoʻa ka nui o nā mea ʻike ma nā kiʻi paʻi kiʻi. ʻOi aku ka liʻiliʻi o ka mea ʻike i loko o ke kelepona ma mua o ka mea ʻike i loko o kahi kāmeʻa meaʻai, ʻoi aku ka liʻiliʻi ma mua o ka sensor i loko o kahi DSLR piha piha. Eia nō naʻe, hiki i nā kāmela ʻekolu ke loaʻa nā sensor 12MP. He aha nā mea e hoʻololi ai i ka nui o ka wahi kukui ma ka sensor. Ma ka pahupaʻikiʻi atamai, liʻiliʻi lākou, a ma kahi pahu pahu piha, ʻoi aku ka nui. Pili kēia i ka maikaʻi o ke kiʻi holoʻokoʻa.
ʻOiai he mea nui e hoʻomaopopo ʻaʻole nā megapixels wale nō ka mea e hoʻopili ai i ka maikaʻi o ke kiʻi. ʻO ka ʻoiaʻiʻo ʻo ka nui o nā megapixels ʻaʻole ia he ʻoi aku ka maikaʻi. Hoʻoholo like ʻia ka maikaʻi o ke kāmela e ka maikaʻi o ka sensor, ʻoi aku ka maikaʻi o nā lens. ʻO ka mea maʻamau, inā ʻoe e hoʻohana i kahi kāmeʻa akamai me nā ʻike maikaʻi ʻole a me nā lens maikaʻi ʻole me nā Megapixels hou aku, e loaʻa iā ʻoe nā pika maikaʻi ʻole.
Pono mākou i nā kāmeʻa megapixel kiʻekiʻe?
ʻO kahi kāmeʻa 12-megapixel i hōʻike ʻia ma ke kua o kahi Google Pixel a i ʻole Apple iPhone e lawe i nā kiʻi kupaianaha, pono ʻoe e nānā i nā kiʻi i hopu ʻia e ka OnePlus 10 Pro, ka Samsung S22, a me ka xiaomi 12 pro e ʻike i nā hopena maikaʻi loa e hiki ai i kēia mau kāmela ke hana pū.
ʻAʻole, ʻaʻole pono ka pahupaʻikiʻi megapixel kiʻekiʻe, he kuleana koʻikoʻi ko Megapixels akā ʻaʻole ʻo ia ke kumu nui i maikaʻi a maikaʻi ʻole paha ka maikaʻi o ka pahu pahu. Nui nā mea e hoʻonui ai i ka pahupaʻikiʻi, a ʻo ka helu megapixel kekahi o ia mau mea, no laila ma mua o kou nānā ʻana i ka nui o nā megapixels o kahi pahupaʻikiʻi atamai, e ʻike pono ua nānā ʻoe i nā mea ʻē aʻe. Mai makapō i nā helu megapixel a e hoʻomanaʻo he ʻāpana koʻikoʻi ka polokalamu o ka hoʻohālikelike kiʻi.
Ke manaʻoʻiʻo nei kekahi o nā kiʻi nui o ka ʻoihana kiʻi kiʻekiʻe he mea ʻino ka smartphone pixel kiʻekiʻe. Ua ʻae ʻo Michael Kaschke, Luna Nui o ka brand lens optical German kaulana ʻo Carl Zeiss (i kapa ʻia ʻo Zeiss) i ka wā i hala. Ua ʻike paha ka poʻe i kamaʻāina i ke kula kelepona ʻo Zeiss ke hāʻawi nei i nā mea lens/ ʻenehana kiʻi no Nokia (HMD), Sony, a me Vivo. No laila, ʻo ka ʻōlelo koʻikoʻi, makemake maoli kēia keonimana i ke kiʻi kiʻi o nā kelepona i kēia lā - no laila no ke aha ʻo ia i hoʻohewa ai i nā kelepona paʻa kiʻekiʻe kiʻekiʻe loa?
Kūʻē maopopo ʻo ia i ka hana o "nā puʻupuʻu lolo ʻole o nā pika". I kona manaʻo, ʻaʻole e haʻi i ka sensor liʻiliʻi o kahi kelepona, ʻoiai ʻo ia ka outsole o kahi SLR piha piha, no ka mea ua paʻa ka nui o ka sensor ponoʻī, ʻo ka hoʻonui ʻana i ka nui o nā pika e hōʻemi i ka wahi photosensitive. o kēlā me kēia pika, a ʻo kēia ka mea e alakaʻi i ka emi ʻana o ka naʻau o ke kukui, e hoʻonui ai i ka walaʻau i ke kiʻi.
ʻO ka hopena, ʻo nā mea hoʻohana kelepona paʻa (kamera) maʻamau, e manaʻo ʻaʻole ʻoi aku ka nui o nā pika i lawe mai i ka maikaʻi o ke kiʻi; a no kēlā poʻe hoʻohana me nā pono ʻoihana, ʻo ia ke ʻano o ka hoʻonui ʻana i nā lako. he hoomaunauna.
Makemake paha kekahi o ʻoukou e kūʻē iā ia ma ka ʻōlelo ʻana "ʻaʻole anei ʻoe i ʻike ʻaʻole i hoʻopili ʻia ka brand XX me kahi CMOS kiʻekiʻe kiʻekiʻe? ʻAʻole anei ʻo ia ke kelepona kelepona inoa XXXX e ʻōlelo nei hiki iā ia ke hoʻohana i ka hana AI e hoʻomaʻamaʻa i ka maikaʻi o ke kiʻi? I ka pane ʻana i kēia, ʻo Kaschke kuhikuhi ʻAʻole hiki ke hana koke i nā kiʻi me 40 miliona a i ʻole nā kiʻekiʻe pika kiʻekiʻe o ka hoʻomanaʻo kelepona paʻalima a me ka hoʻomanaʻo flash.
Ma muli o kēia, ʻo kēlā mau kelepona me ka hoʻolālā pixel ultra-high, me ka ʻole o ka ʻokoʻa, ʻaʻole e hoʻohuli maoli i ka mode pixel ultra-high ma ka paʻamau akā e kiʻi i ke ʻano i kapa ʻia ʻo "ʻehā-i-hoʻokahi". Ma kēia ʻano, ʻaʻole ia e hōʻemi wale i ka hiki o ka walaʻau ma o ka pixel synthesis akā e hōʻemi pū i ke kaomi computational o ka mea hana, e ʻae iā ia e hana i ka hoʻohaʻahaʻa leo maoli, HDR, hoʻonani, etc. ʻOiai ma nā kelepona paʻa hae, ʻaʻole lawa ka "hana" o ke kiʻi ʻana i nā kiʻi
Ke huhū iki nei ʻoe i ka ʻike ʻana i kēia? ʻO kaʻoiaʻiʻo, ua kāhāhā liʻiliʻi wau i koʻu ʻike mua ʻana i ka ʻoiaʻiʻo ʻaʻole hiki i nā kelepona paʻa hae o kēia manawa ke kiʻi i nā kiʻi me 40 megapixels.
Nā'ōlelo hope
No laila pono mākou i nā kāmeʻa megapixel kiʻekiʻe? ʻAe, ʻo ka pane ʻAʻole, aia ka mea ʻai no kahi kāmela kelepona maikaʻi loa i kāna polokalamu, ka mana hana, a me nā mea ʻē aʻe he nui. Hiki i nā megapixel kiʻekiʻe ke ʻoki pono me ka emi ʻole o ka hoʻonā, hopu i nā kiʻi kikoʻī loa, a hoʻonui i ka maikaʻi a me ka ʻoi o ke kiʻi akā inā kaulike ke kaulike kiʻi holoʻokoʻa.
ʻAʻole maopopo pehea e koho ai i kahi kelepona kamera kūpono? Mai hopohopo ua uhi mākou iā ʻoe, E heluhelu i kā mākou ʻatikala ma Pehea e koho ai i ke kelepona kamera maikaʻi i ke kūʻai ʻana i kelepona?
