Grayscale Level Grayscale, inozivikanwawo seyero yeruvara kana grey scale, inoreva kupenya kweruvara. Kune tekinoroji yekuratidzira yedhijitari, greyscale ndiyo inotaridza huwandu hwemavara anoratidzwa. Kazhinji, kukwirira kwemavara machena, kupfuma kwemavara anotaridzwa, mufananidzo wacho unowedzera kutetepa, uye zviri nyore kuratidza zvakapfuma. Iyo grayscale level inonyanya kuenderana nehuwandu hwemabhiti eiyo system A/D shanduko. Ehe, iyo sisitimu yevhidhiyo yekugadzirisa chip, ndangariro, uye yekufambisa sisitimu inofanirwa kupa iyo inoenderana nhamba yemabhiti kuitsigira. Domestic LED inoratidzira inonyanya kushandisa 8-bit processing system, kureva, 256 (28) mazinga egreyscale. Zvichitaurwa zviri nyore, kune 256 kupenya kwakasiyana kubva kutema kuenda kune chena. Uchishandisa mavara matatu ekutanga eRGB, 256×256×256=16,777,216 mavara anogona kuumbwa. Ndiko kuti, iyo inowanzonzi 16 megacolors. Zviratidziro zvepasi rose zvinonyanya kushandisa gumi-bit magadzirirwo masisitimu, zvichireva kuti 1024 mazinga egreyscale, achibvumira iyo RGB yekutanga mavara kugadzira 1.07 bhiriyoni mavara.
Nepo greyscale iri chinhu chakakosha pakuona huwandu hwemavara, haisi nyaya yekumusoro kuri nani. Chekutanga, ziso remunhu harina parinogumira. Chechipiri, kuwedzera huwandu hwemabhiti muhudzamu hwekugadzirisa system kunosanganisira shanduko mune dzakasiyana siyana dzekugadzirisa vhidhiyo, kuchengetedza, kutapurirana, uye scanning, kuwedzera zvakanyanya mitengo uye kudzikisira mutengo-kushanda. Kazhinji, vatengi kana zvigadzirwa zvekutengesa zvinogona kushandisa 8-bit masisitimu, nepo zvigadzirwa zvegiredhi zvekutepfenyura zvichigona kushandisa gumi-bit masisitimu.
Kupenya Kwerusarura Matanho: Kupenya kwerusarura mazinga anoreva huwandu hwemwero wekupenya mumufananidzo unogona kusiyanisa ziso remunhu, kubva kune yakasviba kusvika kune yakajeka. Sezvambotaurwa, mamwe maratidziro ane yakanyanya greyscale mazinga, anosvika 256 kana kunyange 1024 mazinga. Nekudaro, nekuda kwekushomeka kwekunzwa kweziso remunhu kupenya, aya mazinga egreyscale haagone kusiyaniswa zvachose. Mune mamwe mazwi, akawanda ari padyo negreyscale mazinga anogona kuratidzika zvakafanana kuziso remunhu. Uyezve, maonero emunhu ega anosiyana. Kune zviratidziro, iyo yakawanda greyscale nhanho ziso remunhu rinogona kusiyanisa, zvirinani, sezvo iyo inoratidzwa mufananidzo ndeyekupedzisira yekuona kwevanhu. Kuwedzera kupenya kwemazinga ayo ziso remunhu rinogona kusiyanisa, hombe nzvimbo yeruvara yeratidziro, uye yakakura kugona kwayo kuratidza akapfuma mavara. Kupenya kwerusarura mazinga anogona kuongororwa uchishandisa nyanzvi software; kazhinji, skrini yekuratidzira inowana makumi maviri kana kupfuura mazinga anoonekwa seane nhanho yakanaka.
Grayscale Non-linear Transformation: Grayscale isiri-linear shanduko inoreva kushandura greyscale data zvichienderana neempirical data kana imwe arithmetic non{2}}linear relationship usati waipa kuchiratidziro. Nekuda kwekuti maLED midziyo ine mitsetse, maratidziro awo anosiyana neasina-ane mutsara ekuratidza mamonitor echinyakare. Kuona kuti chiratidziro che LED chinopindirana nekwazvino data pasina kurasikirwa negreyscale, kusarudzika kusiri-kwemutsara kwedata regreyscale kunowanzoitwa mune inotevera nhanho yeiyo LED inoratidza system. Huwandu hwemabhiti mune yakashandurwa data inowedzera (kuona kuti hapana greyscale data yakarasika). Iyo 4096-level kana 16384-level grayscale kana yepamusoro inodiwa nevamwe vatengesi vedzimba dzekutonga system zvinoreva saizi ye grayscale space mushure me-kushanduka kwemutsara{12}} nhanho dzinoshandisa 8-bit sosi kuenda ku12-bit 6 nhanho ye8 nhanho, 4 nhanho nhanho ye8, 4 nhanho ye8 kune 16-bit isiri-mutsara shanduko tekinoroji. Shanduko isiri-mutsara uchishandisa 8-bit sosi inonyatso kuguma mune yakakura greyscale nzvimbo pane 8-bit sosi. Kazhinji, inofanira kunge iri 10 bits. Zvakafanana ne greyscale, iyi parameter haisati iri nani iyo yakakura; 12 bits kazhinji inokwana kune dzakawanda shanduko.
