Fahamka xuduudaha guud ee Ultra HD High Speed Camera iyo pa la xiriira
qiyaasaha kamaradaha warshaduhu waxay naga caawin karaan inaan si fiican u fahanno hawlaha kamaradaha oo sidaas awgeed gacan ka geystaan habka xulashada. Sida loo maahmaahdo, caalimku waxa uu arkayaa muuqaalka, khabiirku waxa uu arkayaa tafaasiisha; Faahfaahinta kamaradaha warshadaha waxay ku bilaabmaan cabbirkooda.
1. Qaraarka: Dareemaha kamaradku waxa uu ka kooban yahay pixels badan oo lagu habeeyey matrix. Xallinta waxaa lagu muujiyey iyadoo loo eegayo tirada pixels ee jihooyinka toosan iyo kuwa toosan. Mar kasta oo xalku sareeyo, tirada pixels ee sawirka ayaa sare u kacaysa, waana sii cadeynayaa sawirka. Kaamirooyinka iskaanka goobaha warshadaha ee inta badan la isticmaalo waxay leeyihiin xallinta 1.3 megapixels, 2 megapixels, iyo 5 megapixels; kamaradaha sawirida laynka ah, xalintu waa tirada pixels ee jihada toosan ee dareenka, caadi ahaan 1K, 2K, iyo 6K.
Markaad dooranayso xallinta kamarad-qeexidda sare-yar, waxay kuxirantahay baahida mashruucayaga. Xallinta sare mar walba ma fiicna. Xallinta sare waxay keentaa tiro badan oo xogta sawirka ah, kordhinta kakanaanta algorithms-ka-bacdi-socodka. Intaa waxaa dheer, kamaradaha leh xallinta sare guud ahaan waxay leeyihiin heerar hoose.
2. Cabbirka dareemayaasha
Cabbirka dareemayaasha waxa lagu muujiyay aag la isticmaali karo (dhererka x ballac) ama cabbirka xajmiga (inji). Cabbirrada dareemayaasha caadiga ah waa sida soo socota:
Cabbirka dareemayaasha weyn wuxuu guud ahaan tilmaamayaa in kamaradu ay qaadi karto pixels badan, taasoo keentay cabbirka sawirka weyn.
3. Cabbirka Pixel
Cabbirka Pixel waa aagga pixel kasta. Meelaha pixel-ka yar ee shakhsi ahaaneed waxay keenaan pixels ka badan halkii cutubba, kordhinta xallinta kamarada iyo fududaynta ogaanshaha cilladaha yaryar iyo muuqaal ballaaran. Si kastaba ha ahaatee, marka aagga pixel uu hoos u dhaco, awoodda ceelka buuxa ayaa sidoo kale hoos u dhacda, taas oo horseedaysa hoos u dhaca dhaqdhaqaaqa firfircoon ee kamarada.
4. Qoto dheer ee Pixel
Qoto dheer ee Pixel waxa ay tilmaamaysaa tirada bits ee loo isticmaalo in lagu matalo pixel kasta. Guud ahaan, tirada sare ee jajabyada halkii pixel waxay muujinaysaa awood xoog leh oo lagu muujinayo faahfaahinta sawirka, taasoo keentay in qiimaha midabkiisu sarreeyo, iyo midab qoto dheer. Kaamirooyinka warshaduhu waxay caadi ahaan leeyihiin qoto dheer oo pixel ah 1-bit, 8-bit, 16-bit, 24-bit, iyo 32-bit.
Qoto dheer ee 1-bit waxay isticmaashaa matalaad binary, oo sidoo kale loo yaqaan bandhiga monochrome.
Qoto dheer ee pixel 8-bit waa mid caadi ah, iyadoo la adeegsanayo 8 bits binary si ay u matalaan midabka, oo awood u leh inay matalaan 256 midab; Tani waa waxa inta badan loo yaqaan bandhiga cabbirka cawl.
16-bit waxay isticmaashaa 16 binary bits, oo awood u leh inay matalaan 65,536 midab, taas oo u oggolaanaysa muujinta midabka.
24-bit iyo 31-bit waxay ka dhigan yihiin xitaa macluumaadka midabka qani ah.
5. Dhaqdhaqaaqa Range Dynamic Kala duwanaanshaha wuxuu qeexayaa heerarka cabbirka cawl ee uu pixel kasta kala saari karo. Waa saamiga korantada saturation iyo buuqa wax soo saarka kamarada Kala duwanaansho firfircooni ballaaran ayaa u oggolaanaysa faahfaahinta aagagga aadka u dhalaalaya iyo aadka u madow ee goobta in si cad loo soo bandhigo. Guud ahaan, kamaradaha leh kala duwanaansho firfircooni yar ayaa leh buuq badan, taasoo keentay in sawirro ay ka maqan yihiin tafaasiisha aagagga dhalaalaya iyo kuwa madowba.
