Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe, i-LED yephimbo elincaneisibonisiisetshenziswa kabanzi emakethe.Ifaka ukucaca okuphezulu, ukukhanya okuphezulu, ukugcwaliswa kwesikhala okuphezulu nezinga lokuvuselela eliphezulu, i-LED enephimbo elincaneisibonisiama-s asetshenziswa kakhulu ezindongeni ze-TV, ngemuva kwesiteji, kwezentengiso namagumbi enkomfa.Ukucaciswa okuphezulu nokuhlanganisa okungenamthungo kwe-LED yephimbo elincaneisibonisikudingeka ifakwe iphrosesa yevidiyo esebenza kahle.Kulesi sihloko, sizokwethula ubuchwepheshe obuyisi-8 be-pitch encane ye-LEDisibonisiiphrosesa yevidiyo.
1. Ubuchwepheshe Bokuguqula Isikhala Semibala
I-LEDisibonisiubuchwepheshe bokuguqula isikhala sombala bungobunye bobuchwepheshe obubalulekile bephrosesa yevidiyo.Izikrini ze-LED ezihlukene zisebenzisa izikhala ezinemibala ehlukene, ngakho-ke kuyadingeka ukuguqula isignali yokufaka ibe isikhala sombala esifana nesikrini se-LED ngobuchwepheshe bokuguqula isikhala sombala.Njengamanje, izindawo ezivame ukusetshenziswa ezinemibala i-RGB, i-YUV ne-YCbCr, njll. Ngobuchwepheshe bokuguqula indawo yombala, lezi zikhala zemibala ezihlukene zingaguqulelwa esikhaleni sombala sesikrini se-LED, ukuze kuzuzwe ukukhiqizwa kabusha kombala okunembile.
2. Ubuchwepheshe Bokukhulisa Isithombe
Isixazululo sesikrini esincane se-LED siphezulu kakhulu, futhi ubuchwepheshe bokukhulisa isithombe bungobunye bobuchwepheshe obubalulekile beprosesa yevidiyo.Ubuchwepheshe bokukhulisa isithombe ikakhulukazi buhlanganisa i-algorithm yokuhumusha, i-algorithm yokukhulisa kanye ne-algorithm yokulondoloza umphetho.I-algorithm ye-interpolation ingenye yezobuchwepheshe obuvame ukusetshenziswa kakhulu bokukhulisa isithombe, ngokusebenzisa i-algorithm ye-interpolation ingaba isithombe sokucaca okuphansi ukuya ekwandiseni isithombe esinokulungiswa okuphezulu, ukuthuthukisa ukucaca kanye nemininingwane yesithombe.
3.Ubuchwepheshe Bokulungisa Umbala
Ubuchwepheshe bokulungisa umbala buwubuchwepheshe obubaluleke kakhulu kusiprosesa sevidiyo yesikrini se-LED, ngoba isikrini se-LED enqubweni yokukhiqiza sizovela nakanjani ukushintshashintsha kwe-chromatic, ikakhulukazi ekuxhumaneni kuthambekele kakhulu ekuhlukeni kwe-chromatic.Ubuchwepheshe bokulungisa umbala ngokuyinhloko bubangelwa ukugqama, ukugcwaliswa kwemibala, umbala kanye neminye imingcele iyalungiswa ukuze kuzuzwe ibhalansi yombala nokufana, ukuthuthukisa ukukhiqizwa kombala kwevidiyo.
4. I-Grey Scale Processing Technology
Isikrini esincane se-LED ekubonisweni kwezidingo zesikali esimpunga siphezulu kakhulu, ngakho-ke ubuchwepheshe bokucubungula i-grayscale bubuye bungobunye bobuchwepheshe obubalulekile kumcubunguli wevidiyo.Ubuchwepheshe bokucubungula isikali esimpunga ikakhulukazi busebenzisa ubuchwepheshe be-PWM (Pulse Width Modulation) ukulawula ukukhanya kwe-LED, ukuze ukukhanya kwe-LED ngayinye kulungiswe kahle.Ngesikhathi esifanayo, ubuchwepheshe bokucubungula isikali esimpunga budinga futhi ukuxazulula inkinga yenombolo enganele yamazinga esikali esimpunga ukuze kuzuzwe ukuboniswa kwesithombe okunemininingwane eminingi.
5. I-Pretreatment Technology
Ubuchwepheshe bokucubungula ngaphambilini bubhekisela ekucutshungulweni nasekuthuthukisweni kwesignali yevidiyo ngaphambi kokuboniswa kwesikrini se-LED.Ihlanganisa ikakhulukazi ukuzuza kwesignali, i-denoising, ukulola, ukuhlunga, ukuthuthukiswa kombala nezinye izindlela zokucubungula.Lokhu kwelashwa kunganciphisa umsindo, kuthuthukise ukugqama nokucaca lapho kuthunyelwa amasignali, kuyilapho futhi kuqeda ukuchezuka kombala futhi kuthuthukise ukuba ngokoqobo nokufundeka kwezithombe.
6. Ukuvumelanisa Uhlaka
Ekubonisweni kwesikrini se-LED, ubuchwepheshe bokuvumelanisa ifreyimu bubuye bungobunye bobuchwepheshe obubaluleke kakhulu kuphrosesa yevidiyo.Ubuchwepheshe bokuvumelanisa uzimele bufinyelelwa ngokuyinhloko ngokulawula izinga lokuvuselela isikrini se-LED kanye nezinga lozimele lesiginali yokufaka, ukuze isikrini sevidiyo siboniswe kahle.Ekuxhumaneni kwezikrini eziningi, ubuchwepheshe bokuvumelanisa uzimele bungagwema ngempumelelo ukupeyiza kwesikrini nokuklebhuka nezinye izinkinga.
7.Bonisa Ubuchwepheshe Bokubambezeleka
Isikhathi sokulibaziseka kwesibonisi sesikrini esincane se-LED sibaluleke kakhulu ngoba kwezinye izinhlelo zokusebenza, njengemiqhudelwano ye-E-Sports namakhonsathi, isikhathi sokulibaziseka eside singabangela ividiyo nomsindo ukuthi kungavumelaniswa, okuthinta ulwazi lomsebenzisi.Ngakho-ke, amaphrosesa wevidiyo adinga ukuhlonyiswa ngobuchwepheshe bokubambezeleka kwesibonisi ukuze bathole isikhathi sokulibaziseka esifushane kakhulu.
8.Ubuchwepheshe bokufaka amasignali amaningi
Kwezinye izikhathi, kuyadingeka ukubonisa imithombo yesignali eminingi ngesikhathi esisodwa, njengamakhamera amaningi, amakhompyutha amaningi nokunye.Ngakho-ke, iphrosesa yevidiyo idinga ukuba nobuchwepheshe bokufaka amasignali amaningi, obungathola imithombo yamasignali amaningi ngesikhathi esisodwa, futhi ishintshe futhi ixube isibonisi.Ngesikhathi esifanayo, ubuchwepheshe bokufaka amasignali amaningi budinga futhi ukuxazulula izinkinga zokuxazululwa kwemithombo yesignali ehlukene kanye namazinga ahlukene ozimele ukuze kuzuzwe ukuboniswa kwevidiyo okuzinzile nokushelelayo.
Kafushane, ubuchwepheshe obuyinhloko bephrosesa yevidiyo yesikrini se-LED ye-pitch encane ihlanganisa ubuchwepheshe bokuguqula indawo yombala, ubuchwepheshe bokukhulisa isithombe, ubuchwepheshe bokulungisa umbala, ubuchwepheshe bokucubungula isikali esimpunga, ubuchwepheshe bokuvumelanisa ifreyimu, ubuchwepheshe bokulibaziseka bokuboniswa kanye nobuchwepheshe bokufaka amasignali amaningi.Ukusetshenziswa kwalobu buchwepheshe kungathuthukisa ngempumelelo umphumela wokubonisa nolwazi lomsebenzisi lwesikrini esincane se-LED.Ngokuzayo, ngokuthuthukiswa okuqhubekayo kobuchwepheshe, iphrosesa yevidiyo izothuthukiswa njalo futhi ithuthukiswe ukuze kusetshenziswe isikrini esincane se-LED ukuze ilethe ukusebenza okuhle kakhulu.
