Xa iziboniso ezikhokelwayo zisetyenziselwa kumagumbi okulawula, ii-studio zeTV kunye nezinye iindawo, i-moire ngamanye amaxesha iyenzeka.Eli nqaku liza kwazisa izizathu kunye nezisombululo ze-moire.
Iziboniso ze-LED ziye ngokuthe ngcembe zibe zixhobo zokubonisa eziqhelekileyo kumagumbi olawulo kunye ne-studio zeTV.Nangona kunjalo, ngexesha lokusetyenziswa, kuya kufunyanwa ukuba xa ikhamera yekhamera ijoliswe kwisiboniso esikhokelwayo, ngamanye amaxesha kuya kuba nemigca efana namaza amanzi kunye nemibala engaqhelekanga (njengoko kuboniswe kuMzobo 1), edla ngokubizwa ngokuba yi-Moire pattern.
Umfanekiso woku-1
Zibakho njani iipateni zemoire?
Xa iipateni ezimbini ezinezandi zesithuba zidibana, enye ipateni entsha idla ngokudalwa, edla ngokubizwa ngokuba yi-moire (njengoko kubonisiwe kuMfanekiso 2).
Umfanekiso wesi-2
Umboniso we-LED wemveli wenziwa ngeepikseli ezizimeleyo ezikhupha ukukhanya, kwaye kukho iindawo ezicacileyo ezingakhiyo ukukhanya phakathi kweepikseli.Kwangaxeshanye, izinto photosensitive iikhamera yedijithali kwakhona iindawo photosensitive ezicacileyo ezibuthathaka xa benovakalelo.U-Moire wazalwa xa umboniso wedijithali kunye neefoto zedijithali zikhona.
Indlela yokuphelisa okanye ukunciphisa i-Moire?
Ekubeni intsebenziswano phakathi kwesakhiwo segridi yesikrini sokubonisa i-LED kunye nesakhiwo segridi ye-CCD yekhamera yenza i-Moire, ukutshintsha ixabiso elihambelanayo kunye nesakhiwo segridi yesakhiwo segridi ye-CCD yekhamera kunye nesakhiwo segridi yesikrini sokubonisa i-LED sinokuthi ngokwethiyori. ukuphelisa okanye ukunciphisa i-Moire.
Indlela yokutshintsha isakhiwo segridi ye-CCD yekhamera kunyeUmboniso we-LED?
Kwinkqubo yokurekhoda imifanekiso kwifilimu, akukho zipikseli ezisasazwa rhoqo, ngoko akukho zihlandlo ezisisigxina zendawo kwaye akukho moire.
Ngoko ke, i-moire phenomenon yingxaki eziswa yi-digitalization yeekhamera zeTV.Ukuphelisa i-moire, isisombululo somfanekiso wesiboniso se-LED esifakwe kwi-lens kufuneka sibe sincinci kakhulu kune-spatial frequency ye-photosensitive element.Xa le meko yanelisekile, akunakwenzeka ukuba imivimbo efana ne-photosensitive element ibonakale kumfanekiso, kwaye akuyi kubakho moire.
Ukuze kuncitshiswe i-moire, ezinye iikhamera zedijithali zixhotyiswe ngesihluzo sokudlula esisezantsi ukuze sihluze iindawo eziphezulu ze-spatial frequency emfanekisweni, kodwa oku kuyakunciphisa ukubukhali komfanekiso.Ezinye iikhamera zedijithali zisebenzisa abenzi boluvo abanezandi zesithuba eziphezulu.
Ukutshintsha njani ixabiso elihambelana nesakhiwo segridi yeCCD yekhamera kunye nesikrini sokubonisa i-LED?
1. Guqula i-engile yekhamera.I-Moire inokupheliswa okanye iyancipha ngokujikeleza ikhamera kunye nokutshintsha kancinci i-angle yekhamera.
2. Guqula indawo yokudubula kwekhamera.I-Moire inokupheliswa okanye incitshiswe ngokuhambisa icala lekhamera ukuya kwicala okanye phezulu naphantsi.
3. Tshintsha useto ekugxilwe kulo kwikhamera.Ugxininiso olubukhali kakhulu kunye neenkcukacha eziphezulu kwiipatheni ezineenkcukacha zingabangela i-moire, kwaye ukutshintsha ukugxilwa kokugxila kancinci kunokutshintsha ubukhali kwaye kuncede ukuphelisa i-moire.
4. Guqula ubude obugxile kwilensi.I-lens eyahlukeneyo okanye imimiselo yobude obugxininiswe ingasetyenziselwa ukuphelisa okanye ukunciphisa i-moire.
