Nigute Wakora LED Yerekana Ibisobanuro Byisumbuyeho?

Hamwe niterambere ryiterambere rya siyanse nikoranabuhanga mumyaka yashize, LED yerekanwe yamenyekanye kandi ikoreshwa mubikorwa bitandukanye. Ibirimo byerekanwe biragenda birushaho gusobanurwa. Nigute LED yerekana ishobora kugerahoibisobanuro bihanitse ? Ubwa mbere, ishusho ninkomoko ya videwo bisaba HD yuzuye. Icya kabiri, LED yerekana irasabwa gushyigikira HD yuzuye. Icya gatatu ni ukugabanya pigiseli ikibanza cya LED yerekana. Iya kane ni ihuriro ryerekanwe hamwe na videwo itunganya amashusho. Kugeza ubu, LED yuzuye-ibara ryerekana nayo igenda yerekeza hejuru-ibisobanuro byerekana.

1, Kunoza ikigereranyo cyo gutandukanya ibara ryuzuye LED yerekana. Ikigereranyo gitandukanye nimwe mubintu byingenzi bigira ingaruka kumashusho. Mubisanzwe, nukuvuga itandukaniro, niko ishusho igaragara neza kandi ibara ryiza. Itandukaniro rinini rifasha cyane kumashusho asobanutse no kumurongo urwego rwimikorere. Mubisobanuro bimwe na videwo byerekana itandukaniro rinini ry'umukara n'umweru, itandukaniro-ryinshi ryuzuye ibara LED yerekana ifite ibyiza muburyo butandukanye bwirabura n'umweru, ubukana, n'ubunyangamugayo. Itandukaniro rifite ingaruka nini kumyerekano ya videwo ikora. Kuberako urumuri numwijima byijimye mumashusho afite imbaraga birihuta cyane, uko bihabanye, niko byoroshye kumaso yumuntu gutandukanya inzira yinzibacyuho. Mubyukuri, kunoza ikigereranyo cyo gutandukanya ibara ryuzuye LED ecran ni ukunoza cyane cyane urumuri rwamabara yuzuye LED yerekana no kugabanya ubuso bugaragara bwa ecran. Nyamara, urumuri ntiruri hejuru rushoboka, ruri hejuru cyane, ariko ruzabyara umusaruro, ntabwo rugira ingaruka kumurika rya LED gusa. ubuzima, ariko nanone bitera umwanda. RGB LED yerekana LED module na LED itanga urumuri rukoreshwa muburyo budasanzwe, bushobora kugabanya ububengerane bwumurongo wa LED no kunoza itandukaniro ryerekana RGB LED.

2, Kunoza urwego rwimyenda yamabara yuzuye LED urukuta rwa videwo. Urwego rwimyenda rwerekana urumuri rushobora gutandukanywa kuva mwijimye kugeza kumurabyo muburyo bumwe bwibanze bwamabara yumucyo wuzuye-LED yerekana. Urwego rwohejuru rwimyenda yerekana ibara ryuzuye LED yerekana, ubutunzi bukungahaye kandi burabagirana. Gutezimbere kwurwego rwimyenda irashobora kuzamura cyane uburebure bwamabara, kuburyo urwego rwo kwerekana ibara ryibishusho rwiyongera geometrike. Urwego rwa LED rufite igipimo cyo kugenzura ni 14bit ~ 20bit, ituma ishusho yerekana imiterere irambuye hamwe ningaruka zerekana ibicuruzwa byo mu rwego rwo hejuru byerekana ibicuruzwa bigera ku rwego rwo hejuru ku isi. Hamwe niterambere ryikoranabuhanga ryibikoresho, LED ibara ryinshi izakomeza gutera imbere kugirango igenzurwe neza.

3, Kugabanya pigiseli ikibanza cyamabara yuzuye LED yerekana. Kugabanya pigiseli yikibanza cyuzuye-amabara ya LED yerekana birashobora kunoza neza neza. Gutoya akadomo kerekana ibara ryuzuye LED yerekana, nibyiza kwerekana. Ariko, igiciro cyantoya-LED yerekana ni ku ruhande rwo hejuru. Kubwamahirwe, isoko ubu iratera imbere yerekeza kuri LED ntoya.

4, LED yerekanwe hamwe na progaramu itunganya amashusho. LED itunganya amashusho irashobora gukoresha algorithms igezweho kugirango ihindure ibimenyetso hamwe nubuziranenge bwibishusho, gukora urukurikirane rwo gutunganya nka de-interlacing, gukarisha inkombe, indishyi zigenda, nibindi, kugirango uzamure ibisobanuro birambuye kandi ushimangire ubwiza bwamashusho. Amashusho atunganya amashusho yerekana algorithm ikoreshwa kugirango harebwe niba nyuma yishusho ya videwo imaze gupimwa, urwego rusobanutse kandi rwijimye rwishusho rugumaho kurwego runini. Mubyongeyeho, utunganya amashusho akeneye kandi kugira amahitamo meza yo guhindura amashusho ningaruka zo guhindura, kandi agatunganya ishusho yumucyo, ikinyuranyo, hamwe nicyatsi kugirango yizere ko ecran isohora ishusho yoroshye kandi isobanutse.
