Masewera a Lumens
Poganizira kugula kwa kanema wavideo, mwinamwake kufotokozera momveka bwino komwe mumadziŵa ndi nambala ya kuwala. Lumens ndiyeso yowunikira kanema kanema kanema. Inde, monga momwe zilili ndi zida zina, pamene wopanga amapereka nambala yeniyeni, muyenera kusamala ngati palibe chiwerengero chomwe chiyenera kugwiritsidwa ntchito - motero chiwerengero cha Lumens chogwiritsidwa ntchito ndi mtundu umodzi wa zowonetsera sizingakhale zofanana monga chizindikiro china. Komabe, ngati chiwerengero cha lumens chikulankhulidwa malinga ndi ANSI lumens, ndicho chiwerengero cha mafakitale chomwe chiri chosagwirizana poyerekeza malonda awiri ndi onse akugwiritsa ntchito ANSI monga momwe amachitira.
White Light Output vs Kuwala kwa Mtoto
Komabe, palinso zambiri zomwe muyenera kuziganizira pazinthu zomwe zimawonetsera kuwala kwa kanema kanema. Pamene kulingalira kokhala ndi kuwala kwapadera kumayesedwa, zomwe zimatchulidwa ndi White Light Output (WLO) kapena White Brightness, pulojekitiyo imatha kupanga, osati kuunika kwina kulikonse pamene mtundu ukutengedwa. Mwachitsanzo, pulojekiti iwiri ikhoza kukhala yofanana ndi ya WLO, koma mtundu wowala (CLO), kapena Color Brightness, ukhoza kukhala wosiyana.
Kuyerekezera ndi mbali
Kuti tifotokoze kusiyana pakati pa Kuwala Kwakuyera ndi Mtundu, chithunzichi chakumwamba chikuwonetseratu mbali imodzi ndi mbali zomwe zimakhudza mtundu wa makina owonetsera kanema, kapena kuwala, kutuluka. Onse opanga chithunzi pa chithunzi ali ndi White Brightness yofanana koma amasiyana ndi kuchuluka kwa Kuwala kwa Mbalame komwe angakonze.
Chifukwa chake pali kusiyana pakati pa Kuwala kwa ma polojekiti awiriwa kuti projector kumbali yakumanzere imagwiritsa ntchito 1-chip DLP kupanga (Optoma GT750E), pomwe pulojekiti yomwe ili kumanja imagwiritsa ntchito 3LCD kupanga (Epson PowerLight Home Cinema 750HD). Majekesi onsewa ali ndi chiwonetsero chimodzimodzi ( 720p ) komanso ANSI lumens WLO: 3,000. Chiwerengero cha kusiyana kwa Optoma ndi 3,000: 1 ndipo Epson imatchedwa "mpaka" 5,000: 1.
Komabe, monga momwe mukuonera, pulojekiti yomwe ili kumanja ikuwoneka yowonjezereka, mitundu yowonjezereka, komanso kuwala kwakenthu, kuposa pulojekera kumanzere.
Momwe Pulojekiti Yogwirira Ntchito Imakhudzira Kuwala kwa Mtundu
Chifukwa cha kusiyana pakati pa zithunzi zenizeni, zomwe mukuwona mu chithunzi, ndizogwirizana kwambiri ndi mapangidwe awiriwa. Mpangidwe wa 3LCD umalola kuti kuwala koyera ndi koyera kudutse mu disolo mosalekeza, kufotokoza ndi kufanana kwa White ndi Brightness. Komabe, mu 1-Chip Chipangizo cha DLP , kuwala kumayenera kudutsa gudumu la mtundu wopota lomwe lagawidwa m'magawo ofiira, ofiira, ndi a buluu.
Mu chipangizo cha 1-chip DLP, mitundu imayesedwa sequentially (mwachitsanzo, diso lanu silinapeze mauthenga a mtundu mosalekeza), zomwe zingabweretse kuwala kochepa kwambiri, poyerekeza ndi kuwala koyera. Kulipira izi, opanga 1-chip DLP opanga maulendo ambiri amandiika gawo loyera ku gudumu la mtundu kuti apititse patsogolo Kuwala Pamene, koma zoona zatsikira kuti digiri ya Kuwala ndi yochepa kuposa White Brightness.
Kusiyana kumeneku sikunatchulidwe ndi wopanga muzofotokozera zawo. Zomwe mumakonda kuziwona ndizolemba za Lumens zomwe zimagwiritsidwa ntchito, m'malo mwake zimatha kulemba zizindikiro ziwiri, imodzi ya WLO (White Light Output) ndi imodzi ya CLO (Color Light Output), yomwe imapereka mbiri yeniyeni ya mtundu wa Brightness projector ikhoza kubereka.
Kumbali ina, 3LCD Projectors amagwiritsa ntchito magalasi / magetsi (osasunthira mtundu wa galasi) kuphatikizapo chip chipadera cha mtundu uliwonse (wofiira, umbombo, buluu), choncho zonse zoyera ndi zoyera zimayang'ana diso lanu. Izi zimabweretsa kuunika koyera ndi kowala.
Chifukwa cha teknoloji yomwe imagwiritsidwa ntchito pojambula zithunzi kuchokera ku pulojekiti iliyonse yomwe imagwiritsidwa ntchito pa chithunzi pamwambapa, kuti pulojekiti ya 1-chip DLP kumanzere iwonetsere Kuwala Kwambiri monga 3LCD pulojekiti kumanja, kumafuna kukhala ndi zambiri Mphamvu ya White Light Output kuposa yoyenera pulojekitiyi - izi zikutanthauza kuti 1-chip DLP projector ayenera kugwiritsa ntchito nyali yapamwamba kwambiri, komanso kuwonjezeka kwa mphamvu yogwiritsira ntchito mphamvu.
Kutenga Kotsiriza - Chifukwa Chakuunika Kwambiri Ndikofunika
Monga mukuonera ndi chitsanzo cha chithunzi pamwamba pa tsamba, Kuwala kwa Mtundu kumakhudza mwachindunji zomwe mukuwona pazenera. Izi zikhoza kukhala zofunikira osati osati kuwonetsera kawonekedwe ka nyumba, koma pakuwonera zipinda momwe kuwala kozungulira kumatha kuyang'aniridwa mosavuta, kuyang'ana kwa 3D, kumene kutayika kwa kuwala poona kudzera m'magalasi a 3D ndi chinthu, omwe amagwiritsa ntchito kanema pulojekiti mu maphunziro, bizinesi, kuphatikizapo kuyenda, komwe pulojekiti ingagwiritsidwe ntchito mu zipinda zosiyanasiyana zomwe zimawoneka kuti kuwala sikudziwika.
Ndiponso, kuunika kwa mtundu wowonjezereka kumapangitsanso kuzindikira momwe zinthu zilili m'chithunzicho, mosasamala kanthu za chiwonetsero. Chinthu chokha chomwe chingakhoze kuvutika pamene kuwala kwa mtundu kukuwonjezeka ndi msinkhu wosiyana wosiyana. Komabe, palinso zinthu zina zogwiritsa ntchito kanema zomwe zingakhudze zotsatirazi.
Kuti mudziwe zambiri pa Brightness Standard Standard, onetsani ku Chidziwitso Chovomerezeka ndi Color Brightness Standard White Paper.
Komanso, poyerekeza ndi Kuyeretsa kwa Mtundu wa Zisudzo kuti muzisankha pulojekiti yowonongeka, yang'anani tsamba la Kuyerekeza kwa Pulojekiti ya Kuwala.
Kuti mudziwe zambiri za Lumens ndi Brightness, komanso momwe kanema polojekiti yanu ikufotokozera ndi TV kuwala, tiyang'ane ku nkhani yathu: Mitsamba, Lumens, ndi Kuwala - Ma TV ndi Vesi Mavidiyo .
