Grayscale yog hais txog lub tswvyim tseem ceeb siv los sawv cev rau kev hloov xim xim zoo nkauj hauv cov duab ua. Grayscale theem feem ntau yog li ntawm 0 txog 255, qhov twg 0 sawv cev dub, 255 sawv cev rau dawb, thiab tus lej hauv nruab nrab ntawm cov grey sib txawv ntawm grey. Lub siab dua cov muaj nqis grayscale, cov duab ci ci; Qhov qis dua lub Grayscale tus nqi, tus tsaus nti daim duab.
Grayscale cov nuj nqis yog qhia raws li cov lej yooj yim, pub cov khoos phis tawm kom nrawm nrawm txiav txim thiab kho kom haum thaum ua cov duab. Cov lej no tau yooj yim yooj yim ua kom yooj yim ntawm cov kev ua kom zoo ntawm cov duab ua thiab muab cov peev txheej rau cov duab sib raug zoo.
Grayscale feem ntau yog siv nyob rau hauv kev ua cov duab dub thiab dawb, tab sis nws tseem ua lub luag haujlwm tseem ceeb hauv cov duab xim. Cov muaj nuj nqis grayscale ntawm cov xim duab tau muab xam los ntawm qhov hnyav ntawm qhov peb lub cheeb tsam ntawm RGB (liab, ntsuab, thiab xiav). Qhov hnyav no feem ntau siv peb txoj kev hnyav ntawm 0.299, 0.587, thiab 0.114, coj mus rau peb xim ntawm liab, ntsuab, thiab xiav. Qhov hnyav no txoj kev sib txawv ntawm cov neeg sib txawv ntawm tib neeg cov xim sib txawv, ua rau cov duab hloov dua siab tshiab ntau dua hauv cov yam ntxwv ntawm tib neeg lub qhov muag.
Grayscale ntawm LED Zaub
LED Zaub yog cov zaub ua khoom siv dav siv hauv kev tshaj tawm, kev lom zem, tsheb thauj mus los thiab lwm thaj teb. Nws cov txiaj ntsig tshwm sim ncaj qha cuam tshuam nrog cov neeg siv kev paub thiab cov ntaub ntawv xa cov nyhuv. Hauv LED Zaub, lub tswvyim ntawm Grayscale yog qhov tshwj xeeb tshaj yog vim tias cuam tshuam rau cov xim ua tau zoo thiab cov duab zoo ntawm cov zaub.
Lub Grayscale ntawm cov zaub coj hais txog kev ua tau zoo ntawm ib tus coj LED pixel ntawm cov xim zoo sib txawv. Txawv grayscale nqi sib haum rau qib sib txawv. Qhov siab dua cov gayscale qib, tus nplua nuj cov xim thiab cov ntsiab lus uas cov zaub tuaj yeem ua yeeb yam.
Piv txwv li, lub kaw lus gayscale muaj peev xwm muab 256 gayscale ntau ntau, thaum 12-ntsis gayscale system tuaj yeem muab qib 4096 Grayscale. Yog li no, qib crayscale ntau dua tuaj yeem ua rau cov zaub LED qhia smoother thiab ntau cov duab ntuj.
Hauv LED cov lus qhia, kev ua haujlwm ntawm Grayscale feem ntau nyob ntawm PWM (mem tes dav ntsuas ntsuas). PWM tswj lub ci ci ntawm tus coj los ntawm kev kho cov feem sib piv ntawm lub thiab tawm sijhawm kom ua tiav cov qib grayscale ntau. Hom qauv no tsis tuaj yeem tswj tau qhov tseeb ntawm qhov ci ci, tab sis kuj ua kom zoo txo qis kev noj haus. Los ntawm PWM Technology, LED cov lus tuaj yeem ua tiav nplua nuj Grayscale hloov thaum tswj lub ntsej muag siab kaj lug, yog li muab cov duab me me uas pom cov duab nyhuv.
Grayscale
Qib Grayscale yog hais txog tus naj npawb ntawm gayscale ntau qib, uas yog, tus naj npawb ntawm cov xim sib txawv uas cov zaub tuaj yeem tso tawm. Qhov siab dua cov qib grayscale, tus neeg nplua nuj cov xim ua tau zoo ntawm cov zaub thiab cov ntsiab lus finer. Qeb ntawm cov qib grayscale raws li cov xim muaj xim thiab sib piv ntawm cov zaub, yog li cuam tshuam rau tag nrho cov nyhuv zaub.
8-ntsis grayscale
Lub kaw lus 8-ntsis muaj peev xwm muab 256 Gayscale qib (2 mus rau 8 lub zog muaj txiaj ntsig rau cov khoom lag luam gsplays feem ntau. Txawm hais tias 256 gayscale theem tuaj yeem ntsib cov ntaub ntawv feem ntau, hauv qee qhov kev thov siab high-end
10-ntsis grayscale
Lub cev 10-ntsis gayscale muaj peev xwm muab tau 1024 Grayscale qib (2 mus rau lub zog 10), uas yog cov khoom lag luam muag ntau dua li 8-ntsis grayscale. 10-ntsis grayscale cov tshuab feem ntau siv hauv qee cov ntawv thov siab tshaj plaws, xws li kev kho mob kev kho mob, kev tsim tawm kev tshaj lij, thiab video ntau lawm.
12-ntsis grayscale
Lub 12-ntsis gayscale system tuaj yeem muab cov qib 4096 Grayscale (2 mus rau 12 lub zog (2) Lub 12-ntsis gayscale system feem ntau siv nyob rau qee cov ntawv thov uas xav tau, xws li aerospace, kev saib xyuas tub rog thiab lwm thaj chaw.
Nyob rau hauv LED cov ntxaij vab tshaus, kev ua tau zoo tsis yog nyob ntawm kev pab kho vajtse, tab sis kuj xav tau kev koom tes ntawm software algorithms. Los ntawm cov duab ua kom paub txog cov duab algorithms, cov kev ua tau zoo tuaj yeem tsim tau txuas ntxiv, yog li cov zaub uas pom tau zoo dua ntawm qib siab.

Grayscale yog ib lub tswv yim tseem ceeb hauv kev ua thiab tso duab thev naus laus zis, thiab nws daim ntawv thov hauv LED cov ntxaij vab tshaus yog qhov tseem ceeb. Los ntawm kev tswj tau zoo thiab nthuav tawm ntawm grayscale, LED cov ntxaij vab tshaus tuaj yeem muab cov xim nplua nuj thiab cov duab ntshiab, yog li ua kom cov neeg siv kev pom. Hauv kev siv cov kev siv, xaiv cov qib kev sib tw sib txawv yuav tsum tau txiav txim siab raws li kev siv kev siv thiab daim ntawv teev cov xwm txheej kom ua tiav cov txiaj ntsig zoo tshaj plaws.
Cov kev siv grayscale kev siv ntawm LED cov ntxaij vab tshaus ntawm LEDM thev naus laus zis, uas tswj qhov ci ci ntawm lub sijhawm hloov pauv ntawm cov LEDs kom ua tiav cov kab sib cav sib ceg. Qib ntawm grayscale ncaj qha cuam tshuam cov xim ua tau zoo thiab cov duab zoo ntawm cov zaub vijtsam. Los ntawm 8-ntsis grayscale mus rau 12-ntsis grayscale, daim ntawv thov ntawm cov qib sib txawv sib txawv raws li cov zaub xav tau ntawm cov kev xav tau sib txawv.
Feem ntau, kev txhim kho txuas ntxiv thiab kev nce qib ntawm cov tub rog sib tw ntawm cov thev naus laus zis muab cov dav davdaim ntawv thov kev cia siab rau LED cov ntxaij vab tshaus coj. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho cov duab ua haujlwm ntxiv thiab kev ua tau zoo ntawm cov qauv kev ua tau zoo, kev ua tau zoo tshaj plaws, coj cov neeg siv kev xav tau ntau dua. Yog li ntawd, thaum xaiv thiab siv LED cov ntxaij vab tshaus, ib qho kev nkag siab tob thiab tsim nyog ntawm gayscale technology yuav yog tus yuam sij rau kev txhim kho cov nyhuv pom.
