Uma izibonisi eziholayo zisetshenziswa emakamelweni okulawula, izitudiyo ze-TV nezinye izindawo, i-moire ngezinye izikhathi iyenzeka.Lesi sihloko sizokwethula izimbangela kanye nezixazululo ze-moire.
Izibonisi ze-LED kancane kancane seziphenduke imishini yokubonisa evamile emakamelweni okulawula nasezitudiyo ze-TV.Kodwa-ke, ngesikhathi sokusetshenziswa, kuzotholakala ukuthi uma i-lens yekhamera iqondiswe kusibonisi esiholayo, ngezikhathi ezithile kuzoba nemigqa efana namagagasi amanzi nemibala engavamile (njengoba kuboniswe kuMfanekiso 1), okuvame ukubizwa ngokuthi iphethini ye-Moire.
Umfanekiso 1
Amaphethini e-moire avela kanjani?
Uma amaphethini amabili anamaza ezindawo egqagqene, enye iphethini entsha ivamise ukwakhiwa, ngokuvamile ebizwa ngokuthi i-moire (njengoba kukhonjisiwe kuMfanekiso 2).
Umfanekiso 2
Isibonisi se-LED esivamile sakhiwe ngamaphikseli azimele akhipha ukukhanya, futhi kunezindawo ezisobala ezingakhiphi ukukhanya phakathi kwamaphikseli.Ngesikhathi esifanayo, izakhi ze-photosensitive zamakhamera edijithali nazo zinezindawo ezisobala ezibuthakathaka ze-photosensitive uma zizwela.U-Moire wazalwa ngesikhathi ukuboniswa kwedijithali nokuthwebula izithombe zedijithali kukhona.
Indlela yokuqeda noma ukunciphisa i-Moire?
Njengoba ukusebenzelana phakathi kwesakhiwo segridi yesikrini sokubonisa se-LED kanye nesakhiwo segridi ye-CCD yekhamera kwakha i-Moire, ukushintsha inani elihlobene kanye nesakhiwo segridi yesakhiwo segridi ye-CCD yekhamera kanye nesakhiwo segridi yesikrini sokubonisa se-LED singakwazi ngokombono. ukususa noma ukunciphisa i-Moire.
Ungashintsha kanjani uhlaka lwegridi ye-CCD yekhamera kanyeIsibonisi se-LED?
Enqubweni yokuqopha izithombe efilimini, awekho amaphikseli asakazwa njalo, ngakho-ke akukho mvamisa yendawo engaguquki futhi akukho moire.
Ngakho-ke, ukwenzeka kwe-moire kuyinkinga elethwa ukwenziwa kwedijithali kwamakhamera we-TV.Ukuze kuqedwe i-moire, ukulungiswa kwesithombe esibonisiwe se-LED esithwetshulwe ilensi kufanele kube kuncane kakhulu kunobuningi bendawo bento ethatha izithombe.Uma lesi simo saneliswa, akunakwenzeka ukuthi imivimbo efana ne-photosensitive element ibonakale esithombeni, futhi ngeke kube khona i-moire.
Ukuze kuncishiswe i-moire, amanye amakhamera edijithali afakwe isihlungi se-low-pass ukuze ahlunge izingxenye eziphezulu zefrikhwensi yendawo esithombeni, kodwa lokhu kuzonciphisa ukucija kwesithombe.Amanye amakhamera edijithali asebenzisa izinzwa ezinamaza aphezulu wendawo.
Ungalishintsha kanjani inani elihlobene lesakhiwo segridi ye-CCD yekhamera nesikrini sokubonisa se-LED?
1. Shintsha i-engeli yekhamera.I-Moire ingaqedwa noma incishiswe ngokuzungezisa ikhamera nokushintsha kancane i-angle yekhamera.
2. Shintsha indawo yokuthwebula ikhamera.I-Moire ingaqedwa noma incishiswe ngokuhambisa uhlangothi lwekhamera ohlangothini noma phezulu naphansi.
3. Shintsha izilungiselelo zokugxila kwikhamera.Ukugxila okubukhali kakhulu kanye nemininingwane ephezulu kumaphethini anemininingwane kungabangela i-moire, futhi ukushintsha isilungiselelo sokugxila kancane kungashintsha ukucijile futhi kusize ukuqeda i-moire.
4. Shintsha ubude bokugxila belensi.Amalensi ahlukene noma izilungiselelo zobude obugxilile zingasetshenziswa ukususa noma ukunciphisa i-moire.
