I-greycale ibhekisa kwingcinga ebalulekileyo esetyenziselwa ukumela utshintsho lophawu lwemibala ekuqhubeni imifanekiso. Amanqanaba amaGreycale ahlala ukusuka kwi-0 ukuya kwi-255, apho i-0 imele emnyama, i-255 imele imhlophe, kwaye amanani aphakathi amele amanqanaba ahlukeneyo engwevu. Ngaphezulu kwexabiso ledle, okuqaqambileyo komfanekiso; Ixabiso eliphantsi lexabiso le-grayscale, kumnyama umfanekiso.
Amaxabiso amancinci abonakaliswa njengeenombolo ezilula, avumela iikhompyuter ukuba zenze izigqibo kunye nohlengahlengiso xa kusenziwa imifanekiso. Olu lungiselelo lwamanani lubenza lula ubunzima bendlela yokusebenza yomfanekiso kwaye banika amathuba okumelwa kwemifanekiso eyahlukeneyo.
I-greycale isetyenziswa ikakhulu ekuqhubeni imifanekiso emnyama nemihlophe, kodwa ikwadlala indima ebalulekileyo kwimifanekiso yemibala. Ixabiso le-greyccale lomfanekiso wombala ubalwa ngumndilili wezinto ezintathu ezinomthi ohlukeneyo we-RGB (ibomvu, iluhlaza, kunye neblowu). Lo mgangatho wobuninzi oqhelekileyo usebenzisa imilinganiselo emithathu ye-0.299, 0.14, ihambelana nemibala emithathu yebomvu, eluhlaza, kunye neblowu. Le ndlela yobunzima bayo ivela kwimvakalelo eyahlukileyo yeliso kwimibala eyahlukeneyo, esenza umfanekiso oguqulweyo oguqulweyo ngakumbi kunye neempawu ezibonakalayo zeliso lomntu.
I-Greyscale yoMboniso we-LED
Umboniso we-LED sisixhobo sokubonisa sisetyenziswa ngokubanzi kwintengiso, ukuzonwabisa, ukuthutha kunye namanye amasimi. Iziphumo zayo zokubonisa zihambelana ngqo namava omsebenzisi kunye nefuthe lokuhambisa ulwazi. Kwisibonisi se-LED, umxholo we-greyscale kubaluleke ngakumbi kuba ichaphazela ngokuthe ngqo intsebenzo yombala kunye nomgangatho womfanekiso wesibonisi.
I-greycale yomboniso we-LED ibhekisa kwintsebenzo ye-pixel enye ye-LED kwinqanaba elahlukileyo lokukhanya. Amaxabiso ahlukeneyo amaGreycale ahambelana nenqanaba lokukhanya elihlukileyo. Ngaphezulu inqanaba le-greyscale, isityebi semibala kunye neenkcukacha ezinokubonisa ngazo umboniso.
Umzekelo, inkqubo ye-greycale eyi-8 inokubonelela amanqanaba angama-256 amaGreysCale, ngelixa inkqubo ye-gbi-bi-bit ye-gbitscale inokubonelela ngamanqanaba angama-4096 amaxabiso. Ke ngoko, amanqanaba amaGraycale aphezulu anokwenza i-LED ye-LED yoBoniso loBoniso kunye nemifanekiso yendalo engaphezulu.
Kwimiboniso ye-LED, ukuphunyezwa kwe-greyscale kuhlala kuxhomekeke kwi-PWM (i-pullse yemozulu) yeTekhnoloji yeTekhnoloji. I-PWM ilawula ukuqaqamba kwe-LED ngokuhlengahlengiswa komlinganiso wexesha kunye nokufumana ixesha ukufezekisa amanqanaba amabi. Le ndlela ayinakuwulawula ngokuchanekileyo ukuqaqamba, kodwa inciphise ukusetyenziswa kwamandla. NgeTekhnoloji ye-PWM, imiboniso ye-LED inokuthi ifumane utshintsho lwegraycale ngesityebi ngelixa igcina ukuqaqamba okuphezulu, ngaloo ndlela ibonelela ngefuthe lomfanekiso obukhali ngakumbi.
I-greycale
Ibakala leMali libhekisa kwinani lamanqanaba amadlelo, oko kukuthi, inani lamanqanaba ahlukeneyo okubonisa ukuba umboniso unokuboniswa. Ukuphakama kwebakala lebakala lebakala, ityebile intsebenzo yombala wesibonisi kunye neyona fihlakalo iinkcukacha zomfanekiso. Inqanaba le-Greyscale ngokuthe ngqo ichaphazela ingqiqo yohlobo lombala kunye nawochaseneyo nomboniso, ngaloo ndlela ichaphazela isiphumo sokubonisa.
I-8-bit greycale
Inkqubo ye-8-bit ye-greycale inokubonelela amanqanaba angama-256 amaGreycale (2 ukuya kwi-8 yamandla e-8), elilona nqanaba liqhelekileyo le-graycale kwimiboniso ye-LED. Nangona amanqanaba amaGreycale angama-256 anokuhlangabezana neemfuno zokubonisa ngokubanzi, kwezinye iinkqubo eziphezulu, izicelo ezi-8-bit zisenokungabinakho ukuba zityhafile ngokwaneleyo, ngakumbi xa zibonisa uluhlu oluphezulu (i-HDR).
I-10-bit graycale
Inkqubo ye-10-bit ye-greyccale inokubonelela amanqanaba e-1024 amaGreycale (2 ukuya kwi-10), enomtsalane ngakumbi kwaye itshintshe i-8-bit rayccale. Iinkqubo ezili-10-bit graycale zihlala zisetyenziswa kwezinye izicelo eziphezulu zokubonisa, ezinjengeengcinga zonyango, ukufota kwevidiyo, kunye nemveliso yevidiyo.
I-12-bit graycale
Inkqubo ye-12-bit ye-greycale inokubonelela amanqanaba angama-4096 amaGreycale (2 ukuya kwi-12), eli linqanaba eliphezulu kakhulu kwaye linokubonelela ngendlela yomfanekiso omkhulu. Inkqubo ye-12-bit ye-greyccale ihlala isetyenziswa kwezinye izicelo zokubonisa ezinyanzelekileyo, ezinje nge-aerospace, ukubeka iliso lomkhosi kunye namanye amasimi.
Kwizikrini zokubonisa i-LED, i-Greyscale intsebenzo ayixhomekekanga kwinkxaso ye-harwere, kodwa ifuna ukubambisana kwesoftware yesoftware. Ngomfanekiso ophambili we-algorithms of Algorithms, ukusebenza kwe-greyscale kunokubakho ngakumbi, ukuze isikrini sokubonisa sinokubuyisela ngokuchanekileyo imeko yokwenene kwinqanaba le-grayscale ephezulu.
Ukuqukumbela
I-greycale yintsingiselo ebalulekileyo kwi-intanethi yokulungisa imifanekiso kunye netekhnoloji yokubonisa, kwaye isicelo sayo kwizikrini zokubonisa i-LED sibaluleke kakhulu. Ngolawulo olusebenzayo kunye nentetho yesikrini esibonisa ukuba, isikrini sokubonisa sinokubonelela ngemibala esisityebi kunye nemifanekiso ecekeceke, ngaloo ndlela ukuphucula amava abonakalayo yomsebenzisi. Kwisicelo esisebenzayo, ukukhetha amanqanaba amabizo ahlukeneyo kufuneka kumiselwa ngokweemfuno ezithile zokusetyenziswa kunye neemeko zesicelo zokufezekisa ezona ziphumo zibonakalayo.
Ukuphunyezwa kwe-greycale kwezikrini zokubonisa ezi-LED ikakhulu kuxhomekeke kubuchwepheshe be-PWM, elawula ukuqaqamba kwee-LED ngokuhlengahlengiswa kwexesha lokukhutshelwa kwe-LED yokufezekisa amanqanaba ahlukeneyo e-LED. Inqanaba le-rayscale ichaphazela ngokuthe ngqo intsebenzo yombala kunye nomgangatho womfanekiso wesikrini sokubonisa. Ukusuka kwi-8-bit graycale ukuya kwi-12-bit greyscale, ukusetyenziswa kwamanqanaba amaGrayili ahlukeneyo ahlangabezana neemfuno ezibonisiweyo kumanqanaba ahlukeneyo.
Ngokubanzi, uphuhliso oluqhubekayo kunye nenkqubela phambili yetekhnoloji yegraycale ibonelela ngokubanziisicelo Ithemba lokufumana izikrini ze-LED. Kwixa elizayo, ngokuphuculwa kwetekhnoloji yokuqhubela imifanekiso kunye nokuphuculwa okuqhubekayo kwesixhobo se-Hardware, ukusebenza kwe-Greyscale kwezikrini zokubonisa i-LED kuya kuba yinto ebalaseleyo, yokuzisa abasebenzisi ngakumbi amava abonakalayo. Ke ngoko, xa ukhetha kwaye usebenzisa izikrini zokubonisa i-LED, ukuqonda okunzulu kunye nokusetyenziswa okufanelekileyo kwetekhnoloji yeGreyscale iya kuba yeyona nto iphambili ekuphuculeni isiphumo.
