Okokuqala, sidinga ukuqonda ukuthi yini "i-ripple yamanzi" esibukweni? Igama layo lesayensi laziwa nangokuthi: "Iphethini ye-Moore". Uma sisebenzisa ikhamera yedijithali ukudubula isigcawu, uma kukhona ukuthungwa okuminyene, imigqa engachazeki efana negagasi lamanzi ivamise ukuvela. Lena i-moiré. Kalula nje, i-moiré iwukubonakaliswa komgomo wokushaya. Ngokwezibalo, lapho amaza e-sine e-amplitude amabili alinganayo anamaza asondelene ebekwe phezulu, ubukhulu besiginali ewumphumela buzohluka ngokuya ngomehluko phakathi kwamafrikhwensi amabili.
Kungani kuvela ama-ripples?
1. Isibonisi se-LED sihlukaniswe ngezinhlobo ezimbili: ukuvuselela okuphezulu nokuvuselela okuvamile. Ukubonisa izinga eliphezulu lokuvuselela kungafinyelela ku-3840Hz/s, futhi izinga lokuvuselela elivamile ngu-1920Hz/s. Uma udlala amavidiyo nezithombe, izikrini ezivuselelayo nezijwayelekile zicishe zingabonakali ngeso lenyama, kodwa zingahlukaniswa ngomakhalekhukhwini namakhamera anencazelo ephezulu.
2. Isikrini se-LED esinesilinganiso sokuvuselela esivamile sizoba nama-ripples asobala lapho uthatha izithombe ngomakhalekhukhwini, futhi isikrini sibukeka sicwayiza, kuyilapho isikrini esinezinga eliphezulu lokuvuselela ngeke sibe namaribhole amanzi.
3. Uma izidingo zingekho phezulu noma kungekho mfuneko yokudubula, ungasebenzisa isikrini esiholwa isilinganiso sokuvuselela esijwayelekile, umehluko phakathi kwamehlo anqunu awumkhulu, umphumela ulungile, futhi intengo iyathengeka. Intengo yezinga eliphezulu lokuvuselela kanye nezinga elivamile lokuvuselela lihluke kakhulu, futhi ukukhetha okuqondile kuncike ezidingweni zekhasimende kanye nesabelomali semali enkulu.
Izinzuzo zokukhetha isibonisi se-LED sesilinganiso sokuvuselela
1. Izinga lokuvuselela isivinini isikrini esivuselelwa ngaso. Izinga lokuvuselela lingaphezu kwezikhathi ze-3840 ngomzuzwana, esikubiza ngokuthi ukuvuselela okuphezulu;
2. Izinga eliphezulu lokuvuselela akulula ukuvela i-smear phenomenon;
3. Umphumela wesithombe sefoni ephathekayo noma ikhamera unganciphisa ukwenzeka kwamanzi, futhi bushelelezi njengesibuko;
4. Ukuthungwa kwesithombe kucacile futhi kuthambile, umbala ucacile, futhi izinga lokunciphisa liphezulu;
5. Isibonisi esiphezulu sezinga lokuvuselela sisebenziseka kalula futhi sikhululekile;
Ukucwayiza nokugedla kungabangela ukucinana kwamehlo, futhi ukubuka isikhathi eside kungabangela ukucindezelwa kwamehlo. Lapho izinga lokuvuselela liphakeme, umonakalo omncane emehlweni;
6. Izibonisi ze-LED ezinezinga eliphezulu lokuvuselela zisetshenziswa emakamelweni emihlangano, ezikhungweni zokuyala, emahholo emibukiso, emadolobheni ahlakaniphile, amakhampasi ahlakaniphile, iminyuziyamu, amasosha, izibhedlela, izindawo zokuzivocavoca, amahhotela nezinye izindawo ukuze kugqanyiswe ukubaluleka kwemisebenzi yazo.
