Osiyana The RGB mtundu?

Pasanapite nthawi yaitali, pafupifupi aliyense anakumana pafupifupi kompyuta me pali chofuna kudziwa zomwe ndi mtundu chitsanzo. Mfundozi lipindulitsa kukuza M'maso komanso.

Choncho, pansi pa chitsanzo mtundu ambiri amadziwira chinthu umboni zimenezi, umene aliyense mtundu ukufanizidwa ndi ya manambala. Kodi mtundu uwu chitsanzo, kumene, ali ndi makhalidwe ake komanso kufooka. Mtundu chitsanzo amaganizira chinenero. Mwachitsanzo, mawu akuti "tebulo" kwalembedwa mu zinenero zonse, ndipo zikumveka osiyana, koma zamalankhulidwe katundu ndekha.

Tikumbukenso kuti lero pali zinthu zosiyanasiyana zitsanzo mtundu, koma m'nkhani ino tikambirana yekha mtundu RGB.

nkhani

Mu 1861, Maxwell anapanga maganizo chidwi ntchito mu njira yopangira ochiritsira mtundu chithunzi chomwe pambuyo chinasinthidwa shirokoizvesten monga "zowonjezera maphatikizidwe wa mitundu." Iwo anali zimatanthawuza kuti mitundu ochiritsira maphatikizidwe ndi dongosolo zowonjezera mtundu powonjezera aliyense wakuda. Kachitidwe zowonjezera ndi salembedwa ogaŵikana amamva ndi hardware amadalira.

Kale mu 1931 dongosolo RGB mtundu wakhala bwinobwino yovomerezeka. pa nkhani za Commission la International watenga mtundu danga "CIE 1931 XYZ", amene ankaona m'munsi mpaka lero.

Choyamba, tiona kuti mitundu chitsanzo RGB ndi mmodzi wa anthu otchuka pa mphindi. Mu pempheroli, mitundu RGB zimawoneka mwa prism a mitundu itatu: chofiira (Red), buluu (Blue) ndi zobiriwira (Green). Komabe, pali mitundu iwiri osiyana chitsanzo ichi: eyiti-bit chitsanzo, limene n'chakuti chiwerengero cha makaka osiyanasiyana kuchokera 0 kuti 256, ndipo shestnadtsatibitnaya kumene RGB mtundu anapereka manambala aliyense, koma kuchokera 0 kuti sizinathandize.

Waukulu kusiyana zitsanzo deta ndi zimene zinachitikira m'mbuyo, pakuti m'munsi lililonse (waukulu) mumtundu ndi mzake ntchito sikelo osiyana, ndipo mu Baibulo chachiwiri - mwachindunji anayambitsa hue.

RGB mtundu chitsanzo Mbali kuti pali mtundu watsopano analandira powonjezera mithunzi kale zilipo mitundu chachikulu, ie, pali yotsatana awo "kuyanjana".

Nkofunika kudziwa kuti chitsanzo ichi kawirikawiri amagwiritsidwa ntchito mawonekedwe n'zosangalatsa kumva, koma osati masomphenya. Komanso kufufuza zithunzi ntchito zitsanzo zingapo mumtundu. Chinthu ndi kuti zithunzi RGB mtundu chitsanzo ndi kyubu yaing'ono miyeso itatu, amene si yabwino zokwanira ntchito pa ntchito Mwachitsanzo, mapulogalamu kapena mlengi.

Inde, chitsanzo ichi, RGB ali ndi zovuta zake. The chopambana - ndi kudalira wa panopa hardware wosuta. Chinthu ndi chifaniziro chake pa oyang'anira osiyana amaoneka mosiyana (osiyana khalidwe). Aliyense polojekiti amagwiritsa otchedwa phosphor - ndi chuma chapadera chimene otembenuka mphamvu odzipereka mu alipidwa umuna kuwala, choncho, kuti khalidwe la thunthu ndi kudzadalira fano kenako anasonyeza.
