Iyiphi intetho yekhamera kwifowuni kwaye yintoni na?

Imakethe yefowuni yefowuni igcwele imizekelo ngeekhamera ezinezigqibo ezinkulu. Kukho ii-smartphones ezingabizi ngeenjini kunye nesisombululo sama-megapixels angama-16-20. Umthengi ongenalwazi uyaxosha ikhamera "epholile" kwaye ukhetha ukukhetha kwifowuni enekhamera yesisombululo. Akazi nokuba uyabanjwa kunye ne-bait yabathengisi kunye nabathengisi.

Yintoni isombululo?

Isisombululo sekhamera yiparameter ebonisa ubungakanani bokugqibela bomfanekiso. Inquma kuphela ukuba umfanekiso obangelwayo uza kuba mkhulu kangakanani, oko kukuthi, ububanzi bawo kunye nokuphakama kwiipikseli. Kubalulekile: umgangatho womfanekiso awuguquki. Isithombeni singase siphumelele, kodwa sikhulu ngenxa yemvume.

Imvume ayichaphazeli umgangatho. Kwakungenakwenzeka ukuba ungakhankanyi oku kumxholo wokubhaliweyo kwekhamera ye-smartphone. Ngoku ungaya ngqo ngqo kwindawo.

Iyiphi intetho yekhamera kwifowuni?

Ukubhaliweyo kwekhamera kukunyuka okwenziwe kwisigqibo somfanekiso. Lo mfanekiso, kungekhona ubungakanani bomthamo. Oko kukuthi, isofthiwe ekhethekileyo, ngokubonga ukuba isilathisi esisisombululo se-8 Mp sichazwe kwi-13 Mp okanye ngaphezulu (okanye ngaphantsi).

Ukuba senza umzobo, ukudibanisa kwekhamera kufana neglasi yokukhulisa okanye i-binocular. Ezi zixhobo ziphakamisa umfanekiso, kodwa ungenzi ukuba uphuculise okanye uphawule. Ngoko ukuba ukubhaliweyo kuboniswe kwiimpawu kwifowuni, ngoko isisombululo sangempela sekhamera sinokuthi sibe ngaphantsi kwesigqibo esicacisiwe. Akulunganga kwaye akulungile, kusekhona nje.

Yintoni na?

I-polpolation yanda ukwandisa ubungakanani bomfanekiso, akukho nto. Ngoku kukhohlisayo kwabathengisi nabavelisi abazama ukuthengisa loo mveliso. Zizo manani amakhulu kubonisa kwiposter yentengiso isisombululo sefowuni yekhamera kwaye simise njengenzuzo okanye into entle. Isigqibo esisodwa asichaphazeli kuphela umgangatho wezithombe, ngoko kuya kusenziwa ngokubhaliweyo.

Kwiminyaka eyi-3-4 eyadlulayo abaninzi abavelisi bexoshe inani leegapixel kwaye ngeendlela ezahlukeneyo bazama ukuzitshiloza kwii-smartphones zabo ngeenkokeli ezininzi kangangoko kunokwenzeka. Ngoko kukho iifowuni ezihlakaniphile kunye neekhamera ezinesisombululo se-5, 8, 12, 15, 21 Mp. Ukufotela, bekunokubakho ngexesha elifanayo njengabaphakeli besephahla esancinci, kodwa abathengi, emva kokubona isitika "Ikhamera kwi-18 Mp", ngokukhawuleza babefuna ukuthenga loo fowuni. Ngokuza kwe-interpolation, ukuthengisa ii-smartphones ezinjalo kuye kwaba lula ngenxa yokukwazi ukwenza i-megapixels ekhamera. Ngokuqinisekileyo, umgangatho wesithombe sele uqale ukukhula kunye nexesha, kodwa ngokuqinisekileyo kungekhona ngenxa yesisombululo okanye ukudibanisa, kodwa ngenxa yenkqubela yendalo ngokweendlela zokuphuhlisa izixhobo kunye nesofthiwe.

Icandelo lobugcisa

Iyiphi intetho yekhamera kwifowuni ngokwezobuchule, kuba yonke into ebhalwe ngasentla ichaza ingcamango ephambili?

Ngo kuncedwa kwesoftware ekhethekileyo, iipekseli ezintsha zithathwa ngomfanekiso. Umzekelo, ukwandisa umfanekiso kumanqaku ama-2 emva komgca ngamnye weepekseli esithombeni, umgca omtsha uyongezwa. I-pixel nganye kulo mgca omtsha igcwele umbala. Umbala wokuzaliswa ubalwa ngedemokhrasi ekhethekileyo. Yona ndlela yokuqala kukuzalisa umgca omtsha ngemibala iipixelli ezikufutshane. Isiphumo solu hlobo luya kuba lubuhlungu, kodwa le ndlela ifuna ubuncinci bokusebenza kweekhompyutha.

Ngokuqhelekileyo, enye indlela isetyenziswa. Okokuthi, umqolo omtsha weepekseli wongezwa kumfanekiso wokuqala. I-pixel nganye igcwele umbala, owathi ke, ubalwa njengexabiso eliqhelekileyo lamaphikseli angumakhelwane. Le ndlela inika iziphumo ezingcono, kodwa idinga imisebenzi engakumbi yokuqulunqa.

Ngenhlanhla, iiprosesa ze-mobile zanamhlanje zikhawuleza, kwaye ekusebenzeni umsebenzisi akaqapheli indlela inkqubo ihlela ngayo umfanekiso, uzama ukukhulisa ubungakanani bayo ngobukhulu.

Kukho iindlela ezininzi eziphambili kunye nezilungiso zokubhaliweyo, eziqhubeka ziphucukisiwe: imida phakathi kwemibala iyatshintsha, imigca iya kuba yecacile kwaye icacile. Akunandaba nokuba zonke ezi zilungiswe njani. Ingcamango yenkcazelo yekhamera ibhanal kwaye akunakwenzeka ukuba isetyenziswe kwikusasa elikufutshane. Ngokuncediswa kokubhaliweyo akunakwenzeka ukwenza umfanekiso uphawule, faka iinkcukacha ezintsha okanye uphucule nangenye indlela. Kuphela kwiibhayisikobho, umfanekiso omncinci ocolileyo emva kokusebenzisa ibini yefayile icaca. Ngokwenza oko, oku akunako.

Ngaba udinga ukudibanisa?

Abasebenzisi abaninzi, ngokungazi kwabo, babuza imibuzo kwiifom ehlukeneyo indlela yokwenza ukuchaneka kwekhamera, ikholelwa ukuba iya kuphucula umgangatho wezithombe. Enyanisweni, ukunxibelelana akuyikuphucula kuphela umgangatho womfanekiso, kodwa kunokukwenza kube nzima nakakhulu, kuba ii-pixels ezitsha ziya kwongezwa kwiifoto, kwaye ngenxa yokubala okungekho ngaso sonke isikhathi ngokuchanekileyo kwemibala yokugcwalisa isithomo kukho iindawo ezingenakulinganiswa, ubunqununu. Ngenxa yoko, umgangatho uyawa.

Ngoko ukudibanisa kwifowuni yindlela yokuthengisa engabalulekanga ngokupheleleyo. Inokwandisa isisombululo sezithombe, kodwa neendleko ze-smartphone ngokwayo. Musa ukuwa ngeendlela zokuthengisa abathengisi kunye nabakhiqizi.
