Grayscale zvinoreva pane chakakosha pfungwa inoshandiswa kumiririra shanduko yemavara kupenya mumufananidzo. Grayscale mazinga anowanzo kubva 0 kusvika 255, apo 0 inomiririra nhema, 255 inomiririra chena, uye nhamba dziri pakati dzomiririra madhigirii akasiyana. Yakakwira kukosha kweGraycle kukosha, iyo inopenya chifananidzo; iyo yakadzika iyo grayscale kukosha, yakasviba mufananidzo.
Tsika dzeGrayscale dzinoratidzwa semhando dzakareruka, uchibvumira makomputa kuti zvikurumidze kuita marongero uye kugadzirisa kana kugadzirisa mifananidzo. Iyi inomiririra nhamba yehuwandu nyore nyore nyore kuoma kwemifananidzo yekugadzirisa mifananidzo uye inopa mikana yemumiriri wemifananidzo wakashata.
Graycale inonyanya kushandiswa mukugadzirisa kwemifananidzo nhema uye chena, asi inoitawo basa rakakosha mumifananidzo yemavara. Iko kukoshesa kweguva yemufananidzo wemuenzaniso unoverengwa nehuremu hwakaenzana hwezvinhu zvitatu zvemavara zveRGB (tsvuku, girini, uye bhuruu). Iyi yakaenzana avhareji inowanzo shandisa zviyero zvitatu zve0.299, 0,14, uye inoenderana nemavara matatu ezvitsvuku, girini, uye bhuruu. Iyi nzira inorema inobvambura kubva mukunzwa kwakasiyana kwemaziso emunhu kusvika kune akasiyana mavara, achigadzira iyo inoshandurwa chifananidzo chifananidzo zvakanyanya mukuenzanisa nehunhu hweziso remunhu.
Grayscale ye lED kuratidza
Red Ratiratidziro chiratidzo chechiratidzo chinoshandiswa zvakanyanya mukushambadzira, varaidzo, kutakura uye mimwe minda. Yayo inoratidza maitiro yakanangana zvakananga kune iyo mushandisi ruzivo uye ruzivo rwekuendesa zvinogadzirisa. Mu LED Ratidza, pfungwa yeGraycale inonyanya kukosha nekuti inobata zvakananga kuitwa kwemavara uye mufananidzo wemufananidzo wekuratidzira.
Iyo grayscale yeiyo LED inoratidzira inoreva chiitiko cheimwe yakatungamirwa pixel pixel pane dzakasiyana kwazvo. Dzakasiyana grayscale kukosha kunoenderana nekupenya kwakasiyana. Iyo yakakwira iyo geyscale level, iyo pfuma iyo ruvara uye ruzivo rwunogona kuratidza.
Semuenzaniso, iyo 8-bit Grayscale system inogona kupa 256 grayscale mazinga, nepo gumi nemaviri-grayscale system inogona kupa 4096 grayscale mazinga. Naizvozvo, yepamusoro grayscale mazinga anogona kuita kuti LED kuratidza ratidza zvinyowani uye zvimwe zvakasikwa mifananidzo.
Mu LED inoratidza, kushandiswa kweguva kazhinji kunowanzove kunoenderana nePWM (Pulse Yakarongedzwa Modulation) Tekinoroji. PWM inodzora kupenya kweiyo inotungamirwa nekugadzirisa iyo chiyero cheiyo uye kubva nguva kuti uwane akasiyana maGiriyscale mazinga. Iyi nzira haigone kudzora chaizvo kupenya, asi zvakare inoderedza simba rekushandisa. Kuburikidza nePWM tekinoroji, inoratidzwa inotaridzika inogona kuwana yakapfuma Grayscale ichichengetedza kupenya kwakanyanya, nekudaro ichipa iyo yakaomarara mufananidzo unoratidza.
Grayscale
Giredhi grayscale rinoreva huwandu hwemagamba ekuGrayscale mazinga, ndiko kuti, huwandu hwehuwandu hwakasiyana hwekupenya hunogona kuratidza. Iyo yakakwira giredhi grayscale, rakapfuma ruvara kuita kwechiratidziro uye iyo yakanakisa iyo mifananidzo yemifananidzo. Chikamu chegiredhi graycle zvakananga zvinobata zvakananga ruvara rwekupedzisira uye musiyano wekuratidzira, nekudaro uchikanganisa zvakazara kuratidza maitiro.
8-bit grayscale
Iyo 8-bit Grayscale system inogona kupa 256 grayscale mazinga (2 kusvika kune 8 simba), iyo ndiyo inonyanya kuzivikanwa maGraycale level ye LED inoratidza. Kunyangwe makumi maviri neshanu maGrayscale mazinga anokwanisa kusangana nezvinodiwa zvekuratidzira, mune imwe nzvimbo yakakwira-yekupedzisira-gungwa inogona kunge isingaitike zvakakwana, kunyanya kana ichiratidza yakakwira dynamic (HDR) mifananidzo.
10-bit grayscale
Iyo 10-bit Grayscale system inogona kupa 1024 grayscale mazinga (2 kusvika kune yegumi simba), iyo inonyanya kuderera uye ine inotsemuka mbozha kupfuura 8-bit grayscale. 10-bit Girysale Systems inowanzoshandiswa mune imwe yakakwira-yekupedzisira kuratidza zvikumbiro, sekufungidzira kwekuratidzira, nyanzvi yekutora mifananidzo, uye vhidhiyo kugadzirwa kwevhidhiyo.
12-bit Giriysale
Iyo 12-bit Grayscale system inogona kugovera 4096 Grayscale mazinga (2 kusvika kune yegumi nemaviri), iyo iri yakanyanya girafu hwemagetsi uye inogona kupa zvakanyanya kuderera kwemifananidzo. Iyo 12-bit Girysia system inowanzoshandiswa mune zvimwe zvakanyanya kuda kuratidza mashandisirwo, akadai seAerispace, mauto ekutarisa uye mamwe minda.
Mu LED Ratidza Screens, maitiro eGraycale haingoenderana nerutsigiro rweHardware, asi zvakare zvinoda kubatana kweSoftware algorithms. Kuburikidza neyakagadziriswa mufananidzo Algorithms, kuita kweGraycale kunogona kuwedzeredzwa, kuitira kuti skrini yekuratidzira inogona kudzoreredza zvakanyatsoshandisa iyo chaiyo chiitiko cheGreycale.
Mhedziso
Graycale inhengo yakakosha mumufananidzo uye kuratidza tekinoroji, uye kunyorera kwayo muRed Ratidza Skrini Screens inonyanya kutsoropodza. Kuburikidza nekudzora kwakabudirira uye kutaura kweGrayscale, LED Ratidza Screens inogona kuvapa mavara akapfuma uye akaomesesa mifananidzo, nekudaro achiwedzera ruzivo rwemushandisi. Mune zvinoshanda zvinoshandiswa, kusarudzwa kwehuwandu hweGrayscale mazinga anofanirwa kutsanangurwa maererano nezvakangoita zvekushandisa uye zviitiko zvekushandisa kuti uwane zvakanakisa kuratidza.
Kugadziriswa kweGreycale kweYairongwa Ratidza Screens inonyanya Kuchengetedza Tekinoroji yePWM Iyo nhanho yeGrayscale zvakananga inokanganisa iyo color maitiro uye mufananidzo wemhando yeratidziro yekuratidzira. Kubva pa8-bit grayscale kusvika ku12-bit Giriyka
Kazhinji, kukura kwekuenderera mberi uye kufambira mberi kweGrayscale tekinoroji inopa yakakuraapplication tarisiro yehurongwa hwekuratidzira skrini. Mune ramangwana, nekuenderera mberi kwekuvandudza kwemifananidzo Naizvozvo, kana uchisarudza uye uchishandisa LED Ratidza Screens, nzwisiso yakadzika uye yekushandisa zvine musoro zveinetsamba yeGrayscale ichave iyo kiyi yekuvandudza iyo yekuratidzira.
