Heerka Grayscale Grayscale, oo sidoo kale loo yaqaan heerka midabka ama miisaanka cawl, waxaa loola jeedaa dhalaalka midabka. Tignoolajiyada soo bandhigida dhijitaalka ah, cabbirka cawl waa qodobka go'aamiya tirada midabada la soo bandhigay. Guud ahaan marka loo hadlo, miisaanka sare ee cawl, ayaa hodan ku ah midabada la soo bandhigay, inta badan sawirka jilicsan, oo ay fududahay in la muujiyo faahfaahin qani ah. Heerka cabbirka cawl wuxuu inta badan ku xiran yahay tirada jajabyada beddelka A/D ee nidaamka. Dabcan, qalabka habaynta fiidyaha ee nidaamka, xusuusta, iyo nidaamka gudbinta waa in ay bixiyaan tirada u dhiganta ee loo baahan yahay si ay u taageeraan. Bandhigyada LED-ka ee gudaha waxay inta badan adeegsadaan nidaamka wax-ka-soo-saarka ee 8-bit ah, taas oo ah, 256 (28) heerar cabbir cawl ah. Si fudud loo dhigo, waxaa jira 256 nuurka kala duwanaanshiyaha madow ilaa caddaan. Isticmaalka saddexda midab ee aasaasiga ah ee RGB, 256×256×256=16,777,216 midab ayaa la samayn karaa. Taasi waa, inta badan loo tixraaco 16 megacolor. Bandhigyada summada caalamiga ah ayaa ugu horreyn shaqaaleysiiya nidaamyada wax qabad ee 10-bit, taasoo la macno ah 1024 heerar cawl, taasoo u oggolaanaysa midabada aasaasiga ah ee RGB inay abuuraan 1.07 bilyan oo midab.
In kasta oo cabbirka cawlku uu yahay arrin muhiim u ah go'aaminta tirada midabada, ma aha kiis kan sare ka wanaagsan. Marka hore, xallinta indhaha bini'aadamku waa xaddidan tahay. Marka labaad, kordhinta tirada jajabyada nidaamka qoto dheer ee habaynta waxay ku lug leedahay isbeddelada dhinacyada kala duwan ee habaynta fiidyaha, kaydinta, gudbinta, iyo iskaanka, si wayn u kordhinaysa kharashaadka iyo yaraynta kharashka-waxtarka Guud ahaan, macaamiisha ama alaabada ganacsigu waxay isticmaali karaan 8 - xoogaa habab, halka alaabada heerka baahinta ay isticmaali karaan nidaamyada 10-bit.
Heerarka Takoorka Iftiinka: Heerarka takoorka dhalaalku waxa ay tixraacaan heerka kala duwan ee dhalaalka ee sawirka ay isha bini'aadamku kala saari karaan, min madow ilaa kan ugu iftiimaya. Sida hore loo soo sheegay, bandhigyada qaarkood waxay leeyihiin heerar cawl aad u sarreeya, oo gaaraya 256 ama xitaa 1024 heerar. Si kastaba ha ahaatee, dareenka xaddidan ee isha bini'aadamka ee dhalaalka awgeed, heerarkan cawl si buuxda looma kala saari karo. Si kale haddii loo dhigo, heerar badan oo cawl oo ku xiga ayaa laga yaabaa inay isku mid ula muuqdaan isha bini'aadamka. Intaa waxaa dheer, muuqaalka muuqaalka shakhsi ahaaneed wuu kala duwan yahay. Bandhigyada, heerarka cawl badan ee isha bini'aadamku kala saari karaan, way ka sii wanaagsan tahay, maadaama sawirka la soo bandhigay uu ugu dambeyntii u yahay daawashada aadanaha. Heerarka dhalaalka badan ee isha bini'aadamka ay kala saari karaan, waa sii weynaanaysaa booska midabka ee shaashadda, wayna sii badanaysaa awoodda ay u leedahay inay muujiso midabyo qani ah. Heerarka takoorka dhalaalka waxaa lagu tijaabin karaa iyadoo la isticmaalayo software khaas ah; guud ahaan, shaashada soo bandhigta oo gaadhaysa 20 ama ka badan ayaa loo arkaa inay leedahay heer wanaagsan.
Beddelka Tooska ah -Beddelka Tooska ah: Beddelka Tooska ah ee Grayscale{1}waxaa loola jeedaa beddelka xogta cabbirka cawrada iyadoo loo eegayo xogta la taaban karo ama qaar ka mid ah xisaabta aan{2}}xidhiidh toos ah ka hor inta aan la siinin shaashadda. Sababtoo ah LED-yadu waa aalado toosan, sifooyinkoodu waxay ka duwan yihiin kuwa aan -sifada soo bandhigida toosan ee kormeerayaasha dhaqameed. Si loo hubiyo in muujinta LED-ku ay la mid tahay isha xogta dhaqameed iyada oo aan la lumin heerarka cawl, isbeddel aan toos ahayn{6} ee xogta cabbirka cawrada ayaa guud ahaan lagu sameeyaa marxaladaha dambe ee nidaamka bandhiga LED. Tirada bits ee xogta la beddelay ayaa kordheysa (si loo hubiyo in xog miisaankeedu aanu lumin). Heerka 4096 -heerka ama 16384{15} heerka cawl ama ka sareeya oo ay sheegtaan qaar ka mid ah alaab-qeybiyeyaasha nidaamka kontoroolka gudaha ayaa tixraacaya cabbirka booska cabirka cawliga ka dib heerarka aan{19}}isbeddelka toosan{12}} ayaa isticmaala 8{21}}bit isha heerarka 12-bit ee aan-line 16-bit tignoolajiyada isbeddelka aan toos ahayn. Isbeddel aan toos ahayn oo la isticmaalayo il 8-bit ah ayaa hubaal ah in ay keeni doonto meel bannaan oo cawl ah oo ka weyn il 8-bit ah. Guud ahaan, waa in ay ahaataa ugu yaraan 10 bits. Si la mid ah cabbirka cawl, halbeeggani maahan mid ka wanaagsan inta uu ka weyn yahay; 12-bit ayaa inta badan ku filan isbeddellada intooda badan.
