Kodi zochepa chabe pamalangizo? zitsanzo zosankhidwazi pafupipafupi

Kodi digitization, lero amadziwa katswiri aliyense m'munda wa digito kujambula. Komabe, anthu ambiri amene ayamba chabe kuti ayanjane ndi malowa, sindikudziwa mbali yake yaikulu, kotero kuti akhoza kupewa zolakwa zina.

Ndi chiyani icho?

Kodi zochepa chabe pamalangizo? Izi zotsatira osafunika imbaenda chakuti chithunzi khalidwe liti modziwika sakuyenda. chodabwitsa ukhoza kulumikizidwa ndi chipangizo china chilichonse kapena njira, imene mudziwe lagawidwa zitsanzo zingapo osiyana. Pankhaniyi, zitsanzo zosankhidwazi angathe kuonedwa ngati mtundu wa kusokonezedwa chitsanzo, ngati pali chiyanjano ena pakati pafupipafupi chodabwitsa ndi wapezeka dongosolo zodziwitsa mu deta.

Diso la munthu nthawi zonse amayesetsa kuonetsetsa kuti asazindikire chiŵerengero ena monga kusokonezedwa chitsanzo kuti akhoza zitchinga tanthauzo lenileni la fano. Nkhani zimene zitsanzo zosankhidwazi, ndi kupereka moire chitsanzo, omwe si wolondola ndithu zotsatira zake, koma angasonyeze bwanji munthu kusocheretsedwa choncho pamene chito awiri ayamba kucheza ndi mzake, kupanga lachitatu.

moiré ndi chiyani?

Moire sitingamumvetse wavy chitsanzo, amene poyamba anali sangapezeke pa nkhaniyi. Amenewa ndi zambiri zimachitika pa zithunzi zosiyanasiyana zimene analandira mwa zipangizo yadigito. Ndipo vuto apa ndiye kuti chinthu chitsanzo ndi superimposed pa chitsanzo mayikidwe a pixels pa masanjidwewo ndi, limene pali lachitatu, wotchedwa ndi moire.

Advantageously ambiri a milandu amenewa amapezeka pa Mosiyana zambiri zithunzi okwezeka amene mulibe zizigwirizana chigamulocho poyamba kukhazikitsidwa masensa. Makamaka, angapezeke kawirikawiri zinthu zilili kuchotsedwa monga tsitsi kapena nsalu, komanso ziwembu, yomwe ambiri m'madera chibwereza. Nthawi zambiri, moire sichingapezeke mu chilengedwe, monga kumachitika mafano, amene analandira mwa kamera yadigito kapena aone kenako asamadye.

Nthawi zambiri, mu makamera lero digito, kuti kuchepetsa amenewa, ntchito yapadera kuwala otsika-chiphaso fyuluta, choncho ngati muli zilidi mwaukadaulo ntchito kujambula, mu nkhani iyi, nthawi zonse muyenera kuganizira zitsanzo ndi mbali limene kupezera khalidwe chochuluka malinga sekondale.

Discretization mu makamera zamakono

Masiku ano zipangizo digito, ndi zochepa chabe pamalangizo tingati ndi chifukwa chakuti mfundo lagawidwa zitsanzo zingapo fupipafupi. Makamaka, mmodzi wa dongosolo mu nkhani iyi ndi malo pixels pa masanjidwewo ndi chitsanzo chachiwiri ndi zinthu aliyense mu chifanizo, sipangakhalenso mobwerezabwereza kumbali lalikulu kapena amene udasintha nambala inayake ya pixels mu yopingasa kapena kotenga malangizo.

Kwa amene sadziwa ndi zitsanzo zosankhidwazi ndi zikadzachitika, mungapereke chitsanzo yeniyeni. Pamene pali osakwanira kupezeka kwa chiwerengero cha pixels popereka mauthenga molondola kwa fano, zimene zinachitikira si wabwino. Mu wosasintha zingakhale zokwanira chabe kusankha chikalata apamwamba, motero kuonetsetsa yokonza chiwerengero ofunikira pixels magawo kufala mu chithunzi ndi lolondola ena, ndipo ngati chiwerengero cha pixels sangakhale okwanira, ife tikhoza kumuwona ochepa zinthu za chifanocho.

Komabe, zoona zake n'zakuti zimenezi si zoona. zitsanzo zosankhidwazi chiphunzitso limanena kuti kwenikweni zinthu zambiri zoipa, ndipo ngati tidzapeleka mulibe chiwerengero chokwanira cha pixels kuti kupanga chithunzi chinachake, ndiye chithunzi khalidwe liti poipa mosalekeza.

Kodi pixels ambiri mukufuna?

Mwachitsanzo zinthu pamene pali chithunzi 20 monga wakuda ndi oyera mizere lililonse m'lifupi mwake 5 pixels. Pankhaniyi, ngati mmodzi mapikiselo amaperekedwa kwa aliyense mzere, chithunzi akhoza kulembedwa. Mwachibadwa, ngati pixels musalekane bwino mu mzinda wa aliyense mzere, mu nkhani iyi, wina mapikiselo adzatembenuza imvi, osati kukhala loyera kapena lakuda, ndi mthunzi wake kale mwachindunji kudzadalira mmene mapikiselo ali pabwino wachibale mizere.

Ngati chiwerengero cha pixels m'chifanizo adzakhala ndichepe, ndiye mu Zikatero, ena a iwo kuperekedwa pakati pa mizere, kotero kuti fano limapezeka pamwamba chitsanzo kuti adzakhala mosalekeza ikhoza kusintha kutengera zimene malumikizanidwe ali imeneyi pakati pa mizere ndi chiwerengero cha pixels. Kumene, chithunzichi sadzakhala wofanana kubalana wa pachiyambi, monga dongosolo lokhazikika la mizere kale chimaonekadi chakhungu. Ndi chodabwitsa ichi chotchedwa "deta zitsanzo zosankhidwazi" mabwalo akatswiri.

Kodi kuchita?

Kuti athetse vutoli, m'pofunika kuti afewetse chithunzi pamaso inu kuchepetsa chiwerengero cha pixels. Motero, mungathe kwathunthu tichotse m'mbali lakuthwa pa aliyense mzere, ndi pixels akhoza kutenga mfundo zokhwima. M'mawu ena, fano limakhala lililonse limatisokoneza, koma anapitiriza kuganiza wonse wa fano.

Kodi zimenezi zimakhudza bwanji fano?

Kumene, mobwerezabwereza ndi zonse kapangidwe ka mizere angapezeke yosowa kwambiri ndi zithunzi za zinthu zosiyanasiyana zachilengedwe - pamaso pawo kawirikawiri okha zithunzi za nyumba zosiyanasiyana yokumba monga nyumba ndi zinthu. Komabe, mu Mulimonsemo, kuya zitsanzo zosankhidwazi akhoza chidwi, choncho mawu amenewa nthawi zonse kupewa kuchita zinthu zonse kuwombera.

Dziwani chakuti chifanizo khalidwe angakhale osiyana mwamtheradi, ngakhale nambala yomweyo ya pixels. Ndipotu, mwa zina, kusiyana mafano angakhalenso ndendende mmene zimapezeka. Mwachitsanzo, Ngati munthu, fano Mwina mitigated ndi kudutsa izo kupyolera otsika chikudutsa kutseka kupeza wapakatikati mapikiselo mfundo pamaso kuchepetsa kukula, koma chithu china akhoza kungoyankha yafupika kukula popanda kupangitsa Choncho palibe kusintha osati kupereka mfundo zokhwima pa malire a zinthu pamene pali kusintha mwadzidzidzi kwambiri kuwala.

Kodi kuonanso?

Kumvetsa mmene ntchito, zokwanira basi kutenga chithunzi, ndikuonetsetsa kuti bukuli. Choyambirira fyuluta pamene resizing ndi njira otchedwa zina kuti adzipeza kiyubiki sefa, limene likupezeka muyezo Adobe Photoshop. Choncho, chithunzi adzakhala mitigated. Ngakhale kuchepa Amowabu mu mapikiselo, ndi kusintha pakati tonalities kenako amaoneka yosalala ndi abwino kwambiri kwa chiwerengero kupezeka kwa pixels.

Kenako anapanga buku zithunzi amachepetsa kale, nkuti, 30% ya kukula pachiyambi, pogwiritsa ntchito njira "yapafupi mnansi mfundo" mu dongosolo lomwelo. Kuti ntchito imeneyi potsirizira pake adzakupatsani zochepa chabe pamalangizo tingati zimene zidzaonekera.

Zitsanzo zomvetsera

Audio Zitsanzo - ndi sefa cha phokoso yoweyula pamaso izo adzapulumutsidwa ngati wapamwamba audio. M'mawu ena, chandamale file si buku lenileni la phokoso mafunde, koma idzatha. Pa dzanja limodzi, chitsanzo zomvetsera amapereka yotsimikizika kuchepa file opulumutsidwa, koma Komano pali zambiri Phokoso omveka bwino, amene akhoza sikuti amasunga litayamba mwakhama.

Chotero zosefera phokoso amatchedwa "zitsanzo zosankhidwazi pafupipafupi". Dziwani kuti mfundo yekha mu chikhalidwe palibe phokoso la mawu amenewa, ngakhale pang'ono kudziwa za izo. Zitsanzo zosankhidwazi mlingo - ndi imposition wa gululi yeniyeni phokoso yoweyula, ndi umboni okha zinazake zofunika zinthu.

Lembani kwathunthu zonse phokoso adzakhala kovuta. Ndi chifukwa chake zambiri angapezeke imeneyi ziwiri njira kujambula phokoso anapangidwa ndi zochepa chabe pamalangizo pafupipafupi 44,1 kHz. Yotsirizira zambiri osankhidwa, ili njira yabwino.

Ndipotu, kuganizira processing phokoso, m'pofunika kupereka ulemu wapadera kwa magawo monga wolemba pulogalamu mozama ndi mlingo chitsanzo, chifukwa mitengo ndi apamwamba kwambiri, ndi chizindikiro digito zizigwirizana analogi.
