Guhindura SRGB↔XYZ (2021)

Kuva kuri ecran kugeza mubisanzwe: Ikiraro cyo guhindura amabara

Mwisi yisi, ibara ni ururimi. Kubashushanya, abafotora, nabateza imbere, kwemeza ko umutuku ufite imbaraga kuri monite ari umutuku umwe kuri t-shati yacapwe cyangwa igikoresho gitandukanye nikibazo cyibanze. Aha niho umwanya wamabara no guhinduka kwabo biba ingorabahizi. Mubyingenzi byingenzi muribi byahinduwe harimo ubusobanuro hagati ya sRGB, igipimo cyerekana ibyuma bya digitale, na CIE XYZ, igikoresho cyigenga cyibara ryibanze. Uburyo bwo guhindura iyi mpinduka, bwanonosowe mugihe, byemewe muburyo bushya bwo kuvugurura 2021, butanga ikiraro gikomeye hagati yisi ya digitale numubiri.

Kubucuruzi nka Mewayz, bukora nka OS yubucuruzi busanzwe, ubu buryo bwa tekiniki bufite akamaro. Iyo ucunga umutungo wikirango, amashusho yibicuruzwa, nibikoresho byo kwamamaza kumurongo utandukanye, guhora ibara bihoraho ntabwo biganirwaho. Uburambe bwibara bumwe, bwubatswe kubipimo byizewe, butanga ubunyangamugayo bwurubuga kuva kurubuga rureba kuri terefone kugeza ku gatabo kava mu icapiro ryubucuruzi.

Gusobanukirwa Abakina Ibara: sRGB na CIE XYZ

Kugira ngo twumve ihinduka, tugomba mbere na mbere kumenya abakinnyi b'ingenzi. sRGB (Ibara ritukura ry'icyatsi kibisi) ni umwanya wibanze wurubuga, kamera ya digitale, hamwe nabagenzuzi benshi. Irasobanura urwego rwihariye, cyangwa gamut, yamabara ibyo bikoresho bishobora kubyara. Mugihe hose, sRGB ni gamut ntoya, bivuze ko idashobora kwerekana amabara yose agaragara mumaso yumuntu.

Kurundi ruhande ni CIE XYZ. Yateguwe na komisiyo mpuzamahanga ishinzwe kumurika (CIE) mu 1931, XYZ ntabwo ari umwanya wamabara uhujwe nigikoresho icyo aricyo cyose. Ahubwo, ni imibare yimibare yagenewe gukubiyemo amabara yose umuntu asanzwe ashobora kubona. Ikora nkibisobanuro rusange, "Ibuye rya Rosetta" kubumenyi bwa siyansi. Guhindura ibara kuri XYZ ni nko guhindura ijambo mururimi rusange; kuva aho, irashobora guhindurwa neza mururimi urwo arirwo rwose (cyangwa umwanya wamabara).

Igipimo cya 2021: Gutunganya inzira y'imibare

Inzira yo guhindura kuva sRGB kuri XYZ ikubiyemo urukurikirane rwimibare. Mbere ya 2021, formulaire yo guhindura yari yarashizweho neza ariko ishingiye kubiciro byihariye. Igitabo cya 2021 cyanditswe na CIE, cyiswe "CIE 248: 2021 Gukoresha Umwirondoro wa ICC kuri Data wa sRGB Colorspace Data," ntabwo byagaruye uruziga ahubwo byatanze ibisobanuro byingenzi kandi byerekana indangagaciro nyazo zizakoreshwa mukubara. Ibi byakuyeho ibidasobanutse kandi byemeza ko abategura porogaramu n’abakora ibyuma ku isi hose bakoresha resept imwe.

Inzira yo guhindura ikubiyemo ibyiciro bibiri byingenzi:

• Intambwe yambere nugushira mubikorwa imikorere ya gamma ihindura indangagaciro za sRGB mumurongo wumucyo.
• Guhindura Matrix: Imirongo ya RGB itondekanye noneho igwizwa na matrix yihariye 3x3. Iyi matrisa, isobanuwe neza cyane mubipimo bya 2021, ihindura umurongo wa sRGB kumurongo ugereranije nagaciro ka XYZ gashingiye kumyemerere yumvikanyweho na primaire.

"Icyifuzo cya 2021 gitanga ibisobanuro nyabyo byo guhindura amakuru ya sRGB, bigahuza buri gihe muri sisitemu n'amashusho atandukanye. Ni ikintu cy'ingenzi ku muntu wese ukora mu gucunga amabara." - Incamake ya CIE 248: 2021 akamaro.

Buri kimwe muri ibyo bisohoka gikoresha amabara atandukanye (sRGB kurubuga, CMYK yo gucapa). Mugukoresha impinduka zikomeye, zisanzwe nkinzira ya sRGB-kuri-XYZ, Mewayz irashobora kwemeza ko ibara ryibanze ryibara ryabitswe neza nkuko ritemba hagati ya module nuburyo busohoka. Ibi bivanaho amakosa ahenze, bigabanya inzinguzingo zisubiramo, kandi bikomeza ubudakemwa bwumwuga bwikirango, byose nta mukoresha bigikeneye kumva imibare ishingiyeho.

Mubyukuri, 2021 gutunganya sRGB kuri XYZ ihinduka birenze ibisobanuro bya tekinike; ni ikintu fatizo gishyigikira imicungire idahwitse, yuzuye, kandi yumwuga yibikoresho bya digitale mubucuruzi bwu munsi. Ku mbuga ziyemeje guhinduka no kwizerwa, ubwo busobanuro ntabwo ari ubushake-ni ngombwa.
