Ngā Kāmera Mamati Arotahi Aunoa Tere: Te Auahatanga me te Hangarau i te Wā Hou
Kua tino whanake haere ngā kāmera matihiko mai i tōna whakaurunga mai. Ko tētahi o ngā auahatanga nui o ngā kāmera matihiko ko te pūnaha arotahi aunoa tere. Mā te arotahi aunoa tere ka taea e ngā kaiwhakamahi te hopu whakaahua me te koi teitei me te wā poto, ahakoa kei te neke te kaupapa. Ka tūhuratia e tēnei tuhinga te hangarau kei muri i te arotahi aunoa tere me te pēhea i whakarerekē ai i te ao whakaahua.
He Hītori Poto o te Arotahi Aunoa
I te mutunga o te tekau tau atu i 1970, i whakaurua tuatahitia te arotahi aunoa ki roto i ngā kāmera. I whakamahia e tēnei pūnaha tōmua tētahi tikanga kimi rerekētanga i runga i te aromatawai i te kaha o te mārama e uru ana ki te pūoko. Ahakoa he auaha i tōna wā, he maha ngā ngoikoretanga o tēnei hangarau, pērā i te puhoi o te urupare me te kore tika i ngā āhuatanga mārama iti.
I ngā tau 1980, ka tīmata te puta mai o ngā kāmera me ngā pūnaha arotahi-ā-wāhanga ki te mākete. Ka mahi tēnei pūnaha mā te wehewehe i te mārama e tomo ana ki te pūoko kia rua ngā awa, me te ine i te rerekētanga ā-wāhanga hei whakatau i te arotahi tika. Ka tukuna e tēnei hangarau arotahi-ā-wāhanga he tere ake, he tika ake hoki i te kitenga rerekētanga.
I te taenga mai o te rautau 21, kua eke te arotahi aunoa ki tētahi taumata teitei ake nā ngā whanaketanga hangarau pēnei i te whakamahinga o ngā pūoko CMOS me ngā tukatuka whakaahua tere ake. I ēnei rā, ko te arotahi aunoa tere he āhuatanga paerewa i roto i ngā kāmera matihiko o ēnei rā, mai i ngā kāmera SLR ki ngā kāmera kore whakaata, tae noa ki ngā kāmera waea pūkoro.
Te Hangarau i Muri i te Arotahi Aunoa Tere
He maha ngā hangarau matua e āhei ai te arotahi aunoa tere i roto i ngā kāmera mamati:
1. Te Kimi Āhuatanga i runga i te pūoko
I roto i ngā kāmera o ēnei rā, ka mahia te kimi āhuahanga tika i runga i te pūoko whakaahua, e mōhiotia ana ko te kimi āhuahanga i runga i te pūoko. Mā tēnei hangarau ka taea te arotahi aunoa tere ake, tika ake hoki. Kei te pūoko whakaahua ngā pika AF e āhei ai te ine āhuahanga tika i runga i te pūoko, ka whakaiti i te wā e hiahiatia ana hei whakatutuki i te arotahi tika.
2. Arotahi Aunoa Pika Takirua
Ko te Dual Pixel Autofocus he hangarau i whakawhanakehia e Canon, ā, i whakaurua tuatahitia ki roto i āna kāmera DSLR. E rua ngā photodiode ka wehea ia pika o te pūoko whakaahua hei kite i te mārama motuhake. Mā tēnei ka taea e te kāmera te arotahi tere me te tika, ahakoa te tuhi ataata, te whai rānei i ngā mea e tere haere ana.
3. Pūoko CMOS Mahi Teitei
Kei ngā pūoko CMOS hou ngā āheinga tukatuka raraunga tere-teitei. Ka tautokohia e tēnei te mahi arotahi aunoa tere mā te whakahohe i te tātari whakaahua wā-tūturu. Mā te rere tere o ngā raraunga mai i te pūoko ki te tukatuka whakaahua ka taea e te kāmera te whakarite i ngā whakatikatika arotahi tere me te whai hua.
4. Pūtukatuka Whakaahua Matatau
He mahi nui anō tā te tukatuka whakaahua i roto i ngā pūnaha arotahi aunoa tere. He nui te mana rorohiko o ngā tukatuka hou, pērā i te BIONZ a Sony, te DIGIC a Canon, me te EXPEED a Nikon, hei tukatuka tere i ngā raraunga pūoko. Ko te tikanga o tēnei ka taea te whakamaori tonu i ngā mōhiohio e kohia ana e te pūnaha arotahi aunoa ki ngā whakatikatika arotahi tika.
5. Te Ako Mīhini me te AI
Kei te tīmata hoki te whakamahi i ngā whanaketanga hou o te matauranga horihori (AI) me te ako mīhini ki ngā pūnaha arotahi aunoa a te kāmera. Ka taea e ngā kāmera kua whakauruhia ki te AI te kite i ngā tauira, ngā mata, me ngā mea motuhake, ka taea ai te arotahi tere me te tika. Ka ako tēnei hangarau mai i ngā raraunga kua kohia hei whakapai tonu i te mahi arotahi aunoa i roto i te wā.
Ngā Painga o te Arotahi Aunoa Tere mō ngā Kaiwhakaahua
1. Hopukia Tere te Wā
I te ao whakaahua, ko te wā te mea nui. He painga nui te kaha ki te hopu i ngā wā tino nui i a rātou e tupu ana, ahakoa mō ngā hākinakina, mō ngā kararehe mohoao, mō ngā whakaahua o ia rā rānei. Mā te arotahi aunoa tere ka taea e ngā kaiwhakaahua te hopu whakaahua me te koi tino pai i roto i te kimo o te kanohi.
2. Whakaahua Pumau me te Whakaahua Nekeneke
He tino āwhina te arotahi aunoa tere i ngā āhuatanga e tere haere ana ngā kaupapa. Ka taea e ngā kaiwhakaahua hākinakina, ngā kaiwhakaahua kararehe mohoao rānei te hopu whakaahua koi o ngā mea e neke haere ana i ngā tere teitei. Hei tauira, kua noho te arotahi aunoa pika takirua hei paerewa mō te whakaahua ataata, e āhei ai te arotahi maeneene i te wā e hopu ana.
3. Te Tika Teitei i roto i ngā Āhuatanga Mārama Rerekē
Mā te hangarau hou ka pai te mahi a te arotahi aunoa i ngā āhuatanga mārama iti. He maha ngā wā ka raru ngā pūnaha tawhito i ēnei āhuatanga, engari nā ngā pūoko tairongo ake me ngā tukatuka tere ake, ka taea e ngā kāmera te whakatutuki i te arotahi koi ahakoa i ngā āhuatanga mārama uaua.
4. Arotahi Aunoa me te Arotahi Ā-ringa Pai Ake
Ehara i te mea ko te tere anake te painga. Mā te pūnaha arotahi aunoa tere ka taea e ngā kaiwhakaahua te whakawhiti i waenga i te arotahi aunoa me te arotahi ā-ringa. Mā tēnei ka taea te whakahaere auaha nui ake, me te whakarato tonu i te painga tere o te arotahi aunoa tere ina hiahiatia.
