Matrix yog qhov tseem ceeb ntawm tus yam ntxwv ntawm lub koob yees duab digital niaj hnub, thiab qhov zoo ntawm cov duab ncaj qha nyob ntawm nws zoo. Txawm hais tias muaj lub tswv yim tias kev tsim kho qhov muag zoo thiab muaj txhua yam ntawm cov khoom siv - los ntawm lub teeb lim mus rau sab nraud flashes - yog qhov tseem ceeb tshaj li "lub cev tuag" ntawm lub koob yees duab, koj yuav tsum them nyiaj tshwj xeeb rau hauv matrix thaum yuav khoom.
Lub ntsiab ntawm cov koob yees duab digital matrices
Thaum xaus ntawm lub xyoo pua 20, cov qauv digital hloov pauv cov koob yees duab zoo sib xws. Lawv lub ntsiab sib txawv yog kev siv cov khoom tsim hluav taws xob ua kom zoo nkauj es tsis txhob siv thev naus laus zis. Lub koob yees duab digital sensor hloov cov duab kho qhov muag los ntawm lub lens mus rau hauv lub teeb liab digital. Ob qhov nthuav dav thiab qhov zoo ntawm tag nrho cov txiaj ntsig cov duab nyob ntawm nws.
Txhua qhov chaw sib tw ua los ntawm ntau qhov me me ntawm lub teeb pom kev zoo - pixels, txhua tus ntawm cov uas los ua ib qho duab. Cov ntsuas hluav taws xob sib txawv hauv cov qauv tsim: lawv muaj tag nrho cov thav duab, rov qab ua kom pom kev zoo, thav duab lossis kem ua paug, muaj kev vam meej lossis cuam tshuam.
Ib tug ntawm cov yam ntxwv tseem ceeb ntawm digital lub koob yees duab matrices yog kev daws teeb meem, uas yog, tus naj npawb ntawm pixels. Raws li tau hais los saum toj no, txhua tus ntawm cov pixels pom tau tias lub teeb thiab hloov nws mus rau ib qho taw tes hauv cov duab. Cov pixels ntau dua, qhov ntau dua qhov nthuav dav. Txawm li cas los xij, nws yuav tsum raug sau tseg tias kev nrhiav cov ntawv luam nrog qhov daws teeb meem siab tshaj plaws yog qhov tsis muaj qab hau, vim nws tsis tuaj yeem pom qhov sib txawv ntawm cov duab thaij nrog 10 lub koob yees duab loj thiab hais tias, 12 megapixels nrog lub qhov muag tsis pom.
Qhov loj me muaj teeb meem
Lwm qhov tseem ceeb rau kev ntsuas lub cev yog qhov ntev ntawm lub cev. Qhov loj dua nws yog, qhov zoo dua, txij li ntau lub teeb ntog rau hauv kev ntsuas loj dua. Tias yog vim li cas compact pib xyaum ua "DSLRs" yog ho qis zoo nyob rau hauv zoo rau oversized kev koob yees duab kev. Lub teeb ci ntau dua rau lub ntsuas, lub nqus tsev ntxhua khaub ncaws thiab ntau lub ntuj xim yuav saib thiab lub suab nrov tsis zoo yuav. Txawm li cas los xij, cov tuam ntxhab tau siv los daws cov teeb meem suab nrov nrog kev pab ntawm cov thev naus laus zis ntxiv (suab nrov txo lub tswv yim).
Thaum kawg, cov koob yees duab nrog lub ntsuas loj loj muab qhov tob tob hauv daim teb. Hauv kev xyaum, qhov no txhais tau hais tias tus kws thaij duab muaj peev xwm cais tawm qhov kev kawm los ntawm kev kho qhov tob ntawm daim teb. Ntawd yog, nyob rau hauv cov ntsiab lus yooj yim, txhua yam superfluous yuav pleasantly plooj.
Hmoov tsis zoo, cov tuam ntxhab tsis tshua pom qhov loj me ntawm qhov sib npaug hauv millimetres, tab sis qhia cov tsis muaj nyob hauv vidicon nti, piv txwv li, 1 / 3.2 ", 1 / 1.8", thiab lwm yam. Ntawm no nws yog qhov tseem ceeb rau cov neeg yuav khoom yooj yim kom paub ib qho - tus lej loj hauv tus lej hauv qab, me me qhov loj.
