Indlela yokulinganisa i-CRI?
1- Ukulinganisa i-CRI yokukhanya kwemini
Kufuneka ulandele indlela ye-industry-standard ye-CIE ukulinganisa i-CRI yanoma yimuphi umthombo wokukhanya. Apha, i-radiator yomzimba omnyama kunye nenqaku eligqibeleleyo le-CRI le-100 lithathwa njengesampuli yereferensi. Kufuneka uthelekise unikezelo lombala womthombo wovavanyo kunye nale sampuli. Ukubala ukulinganisa kwe-CRI ngokubanzi, kufuneka ukhethe iisampulu zereferensi ezili-15 eziphambili ngokuqwalasela Iqondo lobushushu yokukhanya okuvavanyiweyo.
I-CIE (1999) ilungelelanise ngokwamanani ezi sampuli zesalathiso kwitshati yoMhloli weMbala. Oku kuqala nge-TCS01, ekubhekiselwa kuyo njenge-'Light Grayish Red,' kwaye iphele nge-TCS15, ekubhekiselwa kuyo 'njengesikhumba sase-Asia.' Ngokusondeleyo umthombo ovavanyiweyo uhambelana nesampulu yereferensi, iphezulu ireyithingi ye-CRI eya kuba nayo.
Sithelekisa imibala ebonakalisiweyo kwaye simisela ngokwefomula isitshixo sombala ngasinye amanqaku “R”.
Ixabiso le-R lombala othile libonisa amandla omthombo wokukhanya ukunika ngokuthembekileyo loo mbala uthile. Ngoko ke, ifomyula ye-CRI ithatha umndilili wamaxabiso e-R ukubonisa amandla onikezelo lombala womthombo wokukhanya.
- I-Ra yi-avareji yexabiso le-R1 ukuya kwi-R8.
- I-AvgR yi-avareji yexabiso le-R1 ukuya kwi-R15.
- Ixabiso elikhethekileyo: R9
Ngokubanzi, kubalo lwe-CRI, iRa yi-avareji ye-R1–R8. Apha, amaxabiso ukusuka kwi-R9 ukuya kwi-R15 awabalwa. Nangona kunjalo, kwizicelo ezifuna isalathiso sombala ophezulu, i-R9 ibalulekile. Imisela amandla omthombo wokukhanya ukubonisa umbala obomvu ngokuchanekileyo. Oko kukuthi, ixabisa umthombo wokukhanya ovavanyiweyo ngokusekelwe kumandla ayo okusondela kwi-TCS 09 yetshathi yeColorChecker.
