Grayscale waxaa loola jeedaa fikrad muhiim ah oo loo adeegsado in lagu matalo isbedelka iftiinka midabka ee sawirka muuqaalka. Heerarka Grayscale badanaa waxay u dhexeeyaan 0 illaa 255, halkaasoo 0 matalayo madow, 255 uu matalayo caddaan, iyo tirooyinka u dhexeeya wakiil ka mid ah heerar kala duwan oo cawlan. Qiimaha sare ee qiimaha gray, muuqaalka ifaya; Qiimaha hoose ee grayscale, muuqaalka mugdiga ah.
Qiimaha grayscale qiimayaasha waxaa loo muujiyaa inay yihiin isugeyn fudud, taasoo u oggolaaneysa kombiyuutarada inay si dhakhso ah u sameeyaan go'aanno iyo is-waafajin marka ay ka baaraandegaan sawirrada. Tacliintani waxay si weyn u fududeynaysaa kakanaanta kakanaanta muuqaalka sawirka waxayna siisaa suurtagalnimada matalaad muuqaal ah oo matalaya.
Grayscale inta badan waxaa loo isticmaalaa ka baaraandegida sawirrada madow iyo caddaan, laakiin waxay sidoo kale door muhiim ah ka cayaartaa sawirada midabka. Qiimaha grayscale ee sawirka midabka waxaa lagu xisaabiyaa celcelis ahaan culeyska culeyska saddexda qaybood ee midabada ee RGB (casaan, cagaar, iyo buluug). Iskucelcelinta miisaanka ah waxay badanaa isticmaashaa saddex culeys oo ah 0.299, 0.587, iyo 0.114, oo u dhigma saddexda midab ee cagaarka, cagaarka, iyo buluuga, iyo buluuga. Qaabkan miisaanka ah wuxuu ka soo qaadayaa dareenka kala duwan ee isha bini-aadamka midabbo kala duwan, taasoo ka dhigeysa sawirka grayscale-ka ah ee la soo rogay oo la jaan qaada astaamaha muuqaalka ee isha bini-aadamka.
Grayscale ee soo bandhigida LED
Bandhigga LED waa aalad soo bandhigeysa oo si balaadhan loogu isticmaalo xayeysiinta, madadaalada, gaadiidka iyo meelaha kale. Saamaynta soo bandhigga ayaa si toos ah ula xiriirta khibradda isticmaale iyo saamaynta gudbinta macluumaadka. Bandhigga LED, fikradda Grayscale ayaa si gaar ah muhiim u ah maxaa yeelay waxay si toos ah u saamaysaa waxqabadka midabka iyo tayada muuqaalka muuqaalka muuqaalka.
Grayscale ee shaashadda hogaaminta waxaa loola jeedaa waxqabadka hal pixel oo keliya heerar dhalaalaya oo kala duwan. Qiimaha kala duwan ee grayscale waxay u dhigantaa heerar dhalaalaya oo kaladuwan. Heerka sare ee Grayscale, oo ah mid ka sareeya midabka iyo tafaasiisha uu soo bandhigi karo.
Tusaale ahaan, nidaamka 8-bit Grayscale wuxuu bixin karaa 256 heerar Grayscale, halka 12-bit Grayscale uu bixin karo heerar 4096 heerar Grayscale ah. Sidaa darteed, heerarka sareeya ee grayscale waxay ka dhigi karaan shaashadda hogaamisa inay muujiyaan sawirro dabiici ah oo jilicsan iyo kuwa kale oo dabiici ah.
Bandhigyada LED-ka, hirgelinta Grayscale badanaa waxay ku tiirsan tahay PWM (Pull ballaadhis) tikniyoolajiyadda. PWM waxay xakameysaa iftiinka hogaaminta iyadoo la hagaajinayo saamiga waqtiga iyo ka damida si loo gaaro heerar kala duwan oo grayscale ah. Qaabkani kaliya uma xakamayn karo iftiinka, laakiin sidoo kale wuxuu si wax ku ool ah u yareeyaa isticmaalka korantada. Iyada oo loo marayo tikniyoolajiyadda PWM, soo bandhigida hogaaminta waxay gaari kartaa isbeddelo hodanka leh ee Grayscale inta ay sii wadeen dhalaalka sare, taas oo ku siinaysa saameyn muuqaal muuqaal badan oo jilicsan.
Grayscale
Grayscale Fasalka Grayscale waxaa loola jeedaa tirada heerarka Grayscale, taasi waa, tirada heerarka iftiinka kaladuwan ee muujinaya in muujinta ay soo bandhigi karto. Waxa kor u kacaya darajada Grayscale, oo ka sareysa waxqabadka midabka ee muujinta iyo wax faahfaahinta muuqaalka muuqaalka. Heerka Grayscale Fasalka si toos ah wuxuu u saameeyaa fadhiga midabka iyo isbarbardhiga shaashadda, taas oo saameyn ku yeelanaysa saameynta guud ee soo bandhigida.
8-bit Grayscale
Nidaamka 8-bit Grayscale wuxuu bixin karaa 256 heerar Grayscale (2 ilaa 8-da korantada), oo ah heerka ugu badan ee grayscale ee soo bandhigida. In kasta oo heerarka 256 heerarka Grayscale ay buuxin karaan baahiyaha shaashadda guud, codsiyada ugu sareeya ee codsiyada dhamaadka, 8-bit Grayscale waxaa laga yaabaa inaysan noqon mid ku filan, gaar ahaan marka ay soo bandhigaan sawirrada heerka sare (HDR).
10-bit Grayscale
Nidaamka 10-ka-bit Grayscale wuxuu bixin karaa heerar 1024 heerar greenscale ah (2 awooda 10-aad), kaas oo ka sii jilicsan oo uu ka badan yahay wareejinta midab ka badan 8-bit Grayscale. Nidaamyada 10-bit Grayscale waxaa badanaa loo isticmaalaa qaar ka mid ah codsiyada muujinta sare, sida sawirka caafimaad, sawir qaade, sawirro xirfad leh, iyo soo-saarka fiidiyowga.
12-bit Grayscale
Nidaamka 12-ka-bit Grayscale wuxuu bixin karaa 4096 heerar Grayscale (2 illaa awoodda 12-aad), oo ah heer aad u sarreeya oo bixin kara qaab muuqaal aad u jilicsan. Nidaamka 12-bit Grayscale waxaa badanaa loo isticmaalaa qaar ka mid ah codsiyada muujinta aad u baahan, sida aerospace, kormeer milatari iyo garoonno kale.
Shaashadda shaashadda ee hogaaminta, waxqabadka grayscale kaliya maahan oo keliya taageerada qalabka, laakiin sidoo kale waxay u baahan tahay iskaashiga algoritwas-ka software-ka. Iyada oo loo marayo sumcadda Sawirka Sawirka Sawirka ah, waxqabadka grayscale-ka ah si dheeraad ah ayaa loo sii wadi karaa, si shaashadda soo bandhigga ay si sax ah ugu soo celin karto goobta dhabta ah ee heerka grayscale heer sare ah.
Gabagabo
Grayscale waa fikrad muhiim ah oo ku saabsan tikniyoolajiyadda muuqaalka iyo muujinta tikniyoolajiyadda, iyo codsigiisa ku jira shaashadda shaashadda hogaaminta ayaa ah mid muhiim ah. Iyada oo loo marayo kontoroolka wax ku oolka ah iyo muujinta grayscale, shaashadda shaashadda ee hogaaminta waxay bixin kartaa midabyo hodan ah iyo sawirro jilicsan, sidaasna loo wanaajinayo khibradda aragga aragga. Codsiyada wax ku oolka ah, xulashada heerarka kaladuwan ee ghroscale waxay u baahan yihiin in lagu go'aamiyo iyadoo loo eegayo shuruudaha gaarka ah ee isticmaalka iyo seenyada arjiga si loo gaaro saameynta soo bandhigga ugu fiican.
Hirgalinta shaashad ee shaashadda ah ayaa inta badan ku tiirsan tikniyoolajiyadda PWM, kaas oo xakameynaya dhalaalaya ee ku dhacaya iyada oo la qabsanayo saamiga waqtiga wareejinta ee loo yaqaan 'The Times' ee LEDSCALL. Heerka Grayscale wuxuu si toos ah u saarayaa waxqabadka midabka iyo tayada muuqaalka shaashadda shaashadda. Laga soo bilaabo 8-bit Grayscale ilaa 12-bit Grayscale, adeegsiga heerarka kaladuwan ee Grayscale ayaa buuxiya baahiyaha shaashadda heerar kala duwan.
Guud ahaan, horumarka joogtada ah iyo horumarka tikniyoolajiyadda Grayscale ayaa bixiya ballaadhanisticmaal rajada laga qabo shaashadda shaashadda. Mustaqbalka, oo leh horumar dheeraad ah oo ku saabsan tikniyoolajiyadda nidaamka samafalka iyo kobcinta joogtada ah ee waxqabadka qalabka, waxqabadka grayscale ee shaashadda shaashadda ee LED waxay noqon doontaa mid aad u badan, oo adeegsanaya isticmaaleyaasha khibrad muuqaal badan oo naxdin leh. Sidaa darteed, markaad dooranayso oo aad isticmaaleyso shaashadda shaashadda hogaaminta, faham qoto dheer oo codsi macquul ah oo ah tikniyoolajiyadda Grayscale ayaa fure u noqon doonta hagaajinta saamaynta soo bandhigida.
