Kev sib raug zoo ntawm cov xim rendering yog dab tsi yog qhov kev sib raug zoo ntawm cov xim rendering Performance index thiab xim rendering?ing Performance index thiab xim rendering?

Thaum muaj me me los yog tsis muaj lub ntsiab nthwv dej tshwm sim los ntawm cov khoom hauv qab siv lub teeb ci hauv qhov spectrum ntawm lub teeb ci, cov xim yuav tsim cov xim sib txawv. Qhov ntau dua qhov sib txawv xim, qhov xim rendering ntawm lub teeb pom kev zoo rau cov xim ntawd. Cov xim rendering index coefficient (Kau fman) tseem yog ib txoj hauv kev los txhais cov xim rendering ntawm lub teeb ci.
Cov xim rendering Performance index ntawm tshav ntuj yog txhais li 100, thiab cov xim rendering Performance index ntawm incandescent teeb yog heev ze rau nruab hnub, yog li nws yog suav hais tias yog ib qho zoo tagnrho siv lub teeb qhov chaw. Cov txheej txheem no siv 8 tus qauv xim qauv nrog nruab nrab chroma los kuaj, sib piv qhov sib txawv ntawm cov 8 xim nyob rau hauv qhov ntsuas lub teeb thiab cov ntaub ntawv siv nrog tib xim kub los ntsuas cov xim rendering Performance index ntawm lub teeb qhov chaw, thiab coj qhov nruab nrab deviation tus nqi. Ra20-100, nrog 100 raws li qhov siab tshaj. Qhov ntau dua qhov nruab nrab xim sib txawv, tus nqi qis dua Ra. Lub teeb ci hauv qab 20 feem ntau tsis haum rau kev siv dav dav.

Lub theoretical xim rendering Performance index ntawm incandescent teeb yog 100, tab sis muaj ntau ntau hom ntawm incandescent teeb nyob rau hauv lub neej tiag tiag thiab txawv daim ntawv thov, yog li lawv Ra qhov tseem ceeb tsis zoo ib yam. Nws tsuas tuaj yeem hais tias lawv nyob ze rau 100, uas yog qhov zoo tshaj plaws xim rendering teeb. Cov xim rendering Performance index qhov tseem ceeb ntawm cov teeb tshwj xeeb tuaj yeem pom hauv cov lus hauv qab no.
