Qib grayscale ntawm tag nrho -xim LED zaub screen yog hais txog tus naj npawb ntawm cov qib brightness nws tuaj yeem pom, thiab yog ib qho tseem ceeb qhia txog kev ua tau zoo ntawm cov xim.
Lus Txhais thiab Kev Ua Haujlwm ntawm Qib Greyscale: Qib Greyscale qhia txog cov qib ci ntsa iab uas lub vijtsam zaub tuaj yeem paub qhov txawv ntawm qhov tsaus ntuj tshaj plaws (dub) mus rau qhov ci tshaj plaws (dawb). Qhov siab dua qib grayscale, qhov smoother lub brightness hloov, lub richer cov xim theem, thiab lub zog ntawm cov duab nthuav dav. Piv txwv li, lub vijtsam qis qis qis qis yuav pom cov xim banding lossis tawg thaum tso tawm cov duab gradient, thaum lub siab greyscale muaj peev xwm nthuav tawm qhov kev hloov pauv ntawm ntuj thiab du.
Lub hauv paus ntsiab lus ntawm Grayscale Level: Grayscale theem feem ntau yog txiav txim siab los ntawm tus lej ntawm cov khoom hauv lub kaw lus A / D hloov dua siab tshiab, thiab tseem yuav tsum tau txhawb nqa kev ua yeeb yaj kiab chips, nco, thiab kis kab mob. Qhov siab dua tus naj npawb ntawm cov khoom hauv A / D hloov dua siab tshiab, qhov ci ntsa iab ntau tuaj yeem sawv cev. Piv txwv li:
8-ntsis system: Muab 256 (2π) grayscale theem, uas yog, 256 brightness variations ntawm dub mus dawb. Tom qab sib txuas 256 qib greyscale rau txhua qhov ntawm peb lub ntsiab xim ntawm RGB, kwv yees li 16.77 lab xim (256 × 256 × 256) tuaj yeem tso tawm . 10-ntsis system: Muab 1024 (21?) qib grey, thiab tuaj yeem tso tawm kwv yees li 1.07 billion xim (1024 × 1024 × 1024 × 1024 × 1024GB) ua ke kev yug me nyuam.
Greyscale qib xaiv thiab tus nqi sib npaug: qib greyscale siab dua tsis yog ib txwm zoo dua; ob qho tib si tib neeg qhov muag kev daws teeb meem thiab cov nqi them nqi yuav tsum tau txiav txim siab:
Tib neeg lub qhov muag daws teeb meem: Tib neeg lub qhov muag muaj qhov txwv tsis pub muaj peev xwm paub qhov txawv qhov ci ntsa iab. Cov qib grayscale siab dhau heev tuaj yeem dhau qhov ntau ntawm tib neeg kev nkag siab, ua rau cov khoom siv khib nyiab.
Tus nqi thiab tus nqi-kev ua tau zoo: Kev nce qib grayscale yuav tsum tau hloov kho cov kev ua yeeb yaj kiab, khaws cia, thiab xa mus, ua rau tus nqi nce ntxiv. Piv txwv li, 10-ntsis system raug nqi ntau dua li 8-ntsis system, tab sis kev txhim kho xim yuav tsis pom zoo rau cov neeg saib nruab nrab.
Application scenario adaptation:
Cov neeg siv khoom lag luam / cov khoom lag luam: Feem ntau siv 8-ntsis system (256 theem ntawm greyscale), ua tau raws li cov kev xav tau ntawm cov zaub txhua hnub thiab muab cov txiaj ntsig zoo.
Tshaj tawm / Cov Khoom Qib Siab: Ua haujlwm 10-ntsis system (1024 qib greyscale), tsim nyog rau kev tsim yeeb yaj kiab thiab TV, kev tshaj tawm siab kawg, thiab lwm yam xwm txheej uas yuav tsum tau muaj xim zoo heev.
Kev cuam tshuam ntawm Grayscale Qib ntawm Cov Khoom Siv
Xim Richness: Qhov siab dua ntawm qib grey, ntau qhov nthuav dav ntawm cov xim uas tuaj yeem ua ke siv RGB thawj xim, ua rau cov duab muaj tseeb dua.
Kev Qhia Txog Tus Neeg Sawv Cev: Cov qib grey nplais siab txo qhov ci ntsa iab, ua cov ntsiab lus xws li duab ntxoov ntxoo thiab gradients kom pom tseeb.
Dynamic Range: Greyscale qib thiab qhov sib piv piv ua ke txiav txim siab qhov ntau yam ntawm lub vijtsam zaub. Cov qib grey nplais siab pab nthuav cov xim dub thiab ci dua.
Cov ntsiab lus: Lub greyscale qib ntawm tag nrho -xim LED zaub screen yog ib qho tseem ceeb qhia ntawm tus naj npawb ntawm cov qib brightness, txiav txim los ntawm tus naj npawb ntawm cov khoom nyob rau hauv lub A / D hloov dua siab tshiab, ncaj qha cuam tshuam rau xim kev ua tau zoo thiab cov duab nthuav dav. Thaum xaiv qhov system, qhov sib npaug yuav tsum raug ntaus ntawm qhov txwv ntawm tib neeg kev pom kev pom thiab tus nqi. Cov xwm txheej ntawm cov neeg siv khoom feem ntau siv 8-ntsis system, thaum cov xwm txheej kev tshaj lij tuaj yeem xaiv 10-ntsis system rau kev tsim cov xim zoo dua.
