Pogula Kachipangizo, Ndikofunika Kudziwa Kusiyana
Ma camcorders ambiri (ngakhalenso mafoni a m'manja) amaphatikizapo njira zamakono zothandizira (IS) zamakono kuti achepetse kuwonetsa kanema komwe kumabwera chifukwa cha manja kapena thupi. Chofunika kwambiri ndi chautatu koma pali mitundu iwiri ya matekinoloje omwe amachititsa patsogolo pake: mawonekedwe ndi digito.
Kukhazikika kwazithunzi ndikofunikira kwa onse opanga ma camcorders, koma ndi ofunika kwambiri kwa omwe amatha kuyenda mofulumira kapena mawotchi otalika kwambiri. Pamene lens likuyendetsedwa mpaka kukwera kwake kwakukulu, imakhala yovuta kwambiri ngakhale kuyendayenda pang'ono.
Okonza ena amaika dzina pazithunzithunzi zawo zolimbitsa chithunzi. Sony imagwiritsira ntchito steadyShot pamene Panasonic imatcha Mega OIS ndi Pentax Shake Kuchepetsa . Aliyense ali ndi maonekedwe awo koma amachita ntchito yomweyo.
Mulimonsemo, nthawi zonse muyenera kuyang'anitsitsa kutsogolo kwa malonda ndikuwonetseratu zomwe zilipo. Iyenera kuwonetsa ngati kamcorder yopatsidwa ili ndi mphamvu kapena yowonjezera.
Kulimbitsa Maonekedwe Otsika
Kulimbitsa chithunzi chazithunzi (OIS) ndi mawonekedwe ogwira mtima kwambiri a chithunzi. Makamera okhala ndi mawonekedwe a optical amakhala ndi timagulu ting'onoting'onoting'ono mkati mwa disolo kuti mwamsanga amasunthira zidutswa za galasi la lens kupita kumalo otseguka asanayambe kusinthidwa kukhala mawonekedwe a digito.
Katswiri wamakono opanga chithunzi amavomereza kuwala ngati iwo ali ndi chinthu chosuntha mkati mwa lens.
Ena opanga camcorder amakupangitsani kutembenuka ndi kutseka mawonekedwe a opaleshoni, kapena kuphatikizapo njira zingapo zothandizira mitundu yosiyanasiyana ya makamera (kaya ofukula kapena osasunthika).
Chithunzi cha Digital Digital Stabilization
Mosiyana ndi mawonekedwe a optical, kugwirizanitsa chifaniziro cha digito (chomwe chimatchedwanso kugwiritsidwa ntchito kwazithunzi zamakono, kapena EIS) chimagwiritsa ntchito luso lamakono kuti lichepetse zotsatira za manja osasangalatsa pavidiyo. Malingana ndi chitsanzo, izi zikhoza kuchitika m'njira zingapo.
Ma camcorders ena amatha kudziwa momwe thupi lanu likugwirira ntchito ndikugwiritsa ntchito detayi kuti musinthe ma pixel omwe ali pamasenema a camcorder akugwiritsidwa ntchito. Amagwiritsa ntchito ma pixel ochokera kumbali yowonekera poyendetsa pang'onopang'ono.
Kwa camcorders ogula makompyuta, chiwonetsero chajambula chojambulidwa nthawi zambiri sichigwira ntchito kusiyana ndi kuyima kwawoneka. Chifukwa chake, zimayenera kuyang'ana mosamala pamene kamcorder imati "imagwirizanitsa." Zingakhale zosiyana zadijito.
Palinso mapulogalamu a mapulogalamu omwe angagwiritse ntchito mafayilo owonetsera ku kanema ngakhale atatengedwa, poyendetsa kayendetsedwe ka pixel ndikusintha fomu. Komabe, izi zimabweretsa chiwonetsero chaching'ono chifukwa cha kuchepa kwa thumba kapena kuchotsera zowonjezereka kuti zitsike m'mphepete mwazitali.
Zithunzi Zamakono Zotsitsimula
Ngakhale kuti mafilimu opangidwa ndi digito ndi otsika kwambiri, matekinoloje ena amayesa kukonza kanema wosasunthika.
Mwachitsanzo, pali machitidwe akunja omwe amatsitsimutsa thupi lonse la kamera mmalo mwa kuti lichitike mkati mwa lensera ya kamera. Njira yomwe imagwira ntchito ndiyo kukhala ndi gyroscope yomwe imakhudza thupi la kamera kuti likhazikike. Izi zimawoneka popanga chithunzi kuchokera ku galimoto yosuntha.
Winanso ndi orthogonal transfer CCD (OTCCD), yomwe imagwiritsidwa ntchito mu zakuthambo kuti zikhazikikebe zithunzi.
