Kuki Monitors zo Gutangaza Amajwi Zisaba Gupima Amabara?
Ibyuma bigenzura amajwi bikoreshwa nk'ibikoresho by'ingenzi mu gufata amashusho, gushyira amabara nyuma yo kuyashyira ku murongo no kuyashyira ku murongo, bigamije kugarura amashusho neza kuri ecran "icyo ubona ari cyo ubona". Ibyuma bigenzura amajwi byanze bikunze bihura n'impinduka mu ibara, urumuri n'ubushyuhe bitewe n'igihe cyo kuyakoresha, impinduka z'ubushyuhe n'uko ibikoresho bisaza. Hatabayeho gupima buri gihe, amakosa yo kureba azagaragara mu kugenzura amabara nyuma yo kuyashyira ku murongo no mu gupima amabara nyuma yo kuyasohora.
Iyo akazi ka nyuma kasohotse kuri televiziyo cyangwa kuri platforms zo kureba amashusho, ibibazo nko kwangirika kw'amabara, urumuri rudahuje n'amabara y'uruhu bizagaragara, bigatera kunanirwa gukorerwa amatangazo kandi bigatera kunanirwa gukora cyangwa kugenzura. Hagati aho, gupima neza bishimangira ko amabara ahoraho mu mikoranire y'itsinda no kugenzura ibikoresho byinshi, birinda amakosa y'amabara mu buryo bwose bwo gukora amashusho.
Amahame ngenderwaho yo gupima imikorere y'amakuru kuri za Monitors zo mu itangazamakuru.
Gusuzuma ikoranabuhanga rya televiziyo bikurikiza amabwiriza rusange y’inganda zikora ibijyanye no gutangaza amakuru ku isi ndetse n’amahame yemewe yo mu gihugu hamwe n’ibipimo by’ingenzi kandi bisobanutse neza.
Ubwa mbere, ku bijyanye n'ahantu hagaragara amabara, SD/HD broadcasting scenarios zikoresha cyane Rec.709, 4K/8K UHD scenarios zikoresha Rec.2020, kandi gukora filime bihuye na DCI-P3 gamut.
Icya kabiri, kugira ngo amabara abe meza, igipimo cy'itandukaniro ry'amabara y'ibanze ΔE kigomba kuba munsi ya 2, kandi ibikoresho by'abahanga bigezweho bigera kuri ΔE <1.5 hamwe n'itandukaniro ry'amabara ritagaragara ku maso y'umuntu; ikosa ry'amabara ry'umuyoboro wose w'itumanaho riri ku gipimo cya 1.0.
Icya gatatu, ku bw'urumuri n'umukara, urumuri rusanzwe rwa monitors za HD ni 300cd/㎡, urumuri rwo hejuru rwa monitors za UHD ni ≥500cd/㎡, naho urumuri rwo hejuru rwa monitors z'umukara ni ≤0.01cd/㎡ kugira ngo harebwe neza igicucu n'imiterere yuzuye y'amabara.
Icya kane, kuri grayscale na gamma, ikurikiza neza imirongo ya gamma ihoraho ifite grayscale imwe kandi idafite uruhande, ikurikiza amabwiriza yemewe ya UHD TV mu gutunganya no gusakaza. Byongeye kandi, gupima bishyigikira hardware LUT mapping kugira ngo ifunge ibipimo by'amabara ku rwego rwa hardware kugira ngo haboneke amashusho ahamye kandi yunze ubumwe.
Itandukaniro ry'amabara hagati ya Ecran za Broadcast na Ecran z'abaguzi.
Itandukaniro ry'ingenzi riri mu mwanya wazo: abashinzwe gukurikirana ibiganiro bashyira imbereibara rikwiye, mu gihe ibyo abaguzi bagaragaza bishyize imbereubunararibonye mu bwenge, hamwe n'ibitandukanye bitatu byihariye.
Ubwa mbere, uburyo butandukanye bwo kureba amabara. Abakurikirana amajwi bakurikirana ukuri kw'amabara nta kuvugurura amabara cyangwa kongera ubushobozi bwo kuyashyira mu mwanya wayo, bagarura 100% by'amabara y'umwimerere. Ibyerekanwa n'abakoresha (mudasobwa, televiziyo zo mu rugo) bihita bitanga urumuri rw'amashusho, byongera ubushobozi bwo kuyashyira mu mwanya wayo no kuyashyira mu mwanya wayo kugira ngo birusheho kunoza uburyo bwo kureba imyidagaduro, bigatuma amabara ahinduka.
Icya kabiri, uburyo bwo gukora neza no guhagarara neza bitandukanye. Buri ecran ikoresha uburyo bwo gukora amashusho ikoreshwa mu ruganda, imwe imwe kandi igashyigikira uburyo bwo gukora amashusho buri gihe, ifite agaciro ka ΔE gake cyane, urumuri rudahindagurika, na grayscale mu gihe kirekire. Ecran zikoreshwa n'abakoresha zishyigikira uburyo bwo gukora amashusho gusa, nta buryo bwo gukora amashusho bujyanye n'uburyo bwa kinyamwuga, zifite itandukaniro rinini ry'amabara, amabara ya ecran adahuye neza, ndetse n'impinduka zikomeye mu gihe kirekire.
Icya gatatu, uburyo butandukanye bwo gukoresha. Ibikoresho byo gusakaza bitanga umusaruro w’umwuga no gusakaza, bikurikiza amabwiriza agenga gusakaza kugira ngo bibe byiza ko bisohoka ku mbuga nyinshi. Ibikoresho bikoreshwa n’abaguzi ni ibyo mu biro no mu myidagaduro ya buri munsi nta mabara ahuye, bigatuma habaho itandukaniro rinini ry’ibikoresho bimwe ku bikoresho bitandukanye, bityo ntibishobora gukoreshwa nk’ibipimo by’umusaruro.
