Computer Zojambula: kuya mtundu

Chibwenzi luso ndi zipangizo kulola kuti yowala ndiponso yomveka bwino chithunzi kuti adzakhala okongola koposa zinachitika wake weniweni. Khalidwe la fano opatsirana kumatengera zifukwa zingapo: chiwerengero cha megapixels, kukula image, chithunzi ndi zina zotero. Zikuphatikizapo katundu wina - kuya mtundu. Kodi izo, ndi momwe kumasulila ndi kuwerengera?

Mtundu kuya - pazipita chiwerengero cha mithunzi ya mtundu kuti zitha muli fano. kuchuluka Izi amayezedwa Akamva (chiwerengero cha Akamva bayinare kuti kudziwa mtundu ndi hue aliyense mapikiselo mu ndi raster zithunzi image). Mwachitsanzo, munthu mapikiselo, kuya mtundu uli wofanana 1 pang'ono mwina kuganiza mfundo ziwiri: woyera ndi wakuda. Ndipo kufunika koposa kukhala akuya mtundu, fano m'ndime yachiwiri chikukhudza ndi kuchuluka kwa mitundu ndi mithunzi. Iye ali ndi udindo kwa fano sanakhulupirike nayenso. Apa, chirichonse chiri njira yomweyo: apamwamba bwino. Chitsanzo china, gif mtundu chithunzi ndi kuya mtundu wa 8 Akamva, kodi muli 256 mitundu, pamene JPEG mtundu chifaniziro ndi akuya Akamva 24 anaphatikizapo mitundu 16 miliyoni.

A pang'ono RGB ndi CMYK

Childs, onse a akamagwiritsa chithunzi deta ndi mtundu akuya Akamva 8 pa njira imodzi (mtundu). Koma chithunzi akhoza kukhala pano, ndipo njira angapo mtundu. Ndiye kale kujambula njira RGB atatu ndi akuya Akamva 24 (3h8). Kuzama CMYK mtundu mafano mpaka 32 Tinthu (4x8).

Koma pang'ono

Mtundu kuya - chiwerengero cha mithunzi ya mtundu woterewu umene chipangizo mu kukhudzana ndi mafano, angathe kubereka kapena kulenga. chizindikiro ichi ndi udindo kusintha yosalala mithunzi ku mafano. Zithunzi zonse digito ndiyotengera mwa anthu ndi maziro. Ziro - wakuda, Unit - White. Kusunga anasunga mu kukumbukira amayezedwa mabayiti. mamvekedwe uli 8 Akamva, amene amaimira ndi kuya mtundu. Pakuti makamera digito, pali tanthauzo lina la masanjidwewo ndi kuya kwa mtundu. Ichi ndi chizindikiro kuti Mzimuyo mmene chithunzi zonse ndiponso mwa mawu a mumthunzi ndi mitundu zingabweretse kamera, ndipo makamaka masanjidwewo ake. Chifukwa mtengo wapatali wa chizindikiro ichi, zithunzi ndi bulky ndi yosalala.

Ulalo pakati pa mtundu mozama ndi fano khalidwe ndi mapeto ake. Mwachitsanzo, 32-bit fano ndi Maganizo a 800x600 ndi kwambiri woipa kuposa ndi 1440x900 ofanana. Inde, mu nkhani wachiwiri izo nawo nambala wokulirapo wa pixels. Izi n'zosavuta kwambiri kuti anu. Zonse muyenera kuchita - ndi kupita PC mu "Image Kusintha" ndi kuyesa zonse kuchepetsa kapena kuonjezera chigamulocho chophimba. Pa ndondomeko imeneyi, mudzakhala bwino kutsimikizira mmene chigamulocho zimakhudza khalidwe la mafano opatsirana. Kaya mitundu yambiri zikuphatikizapo fano makamaka, adzakhululukidwa okha mtengo pazipita zomwe zimathandiza ndi polojekiti. Mwachitsanzo tikhoza kutenga polojekiti ndi 16 pang'ono mtundu mozama ndi fano ndi 32 Tinthu. chithunzi ichi pa polojekiti ndi adzasonyeza akuya ngati mtundu 16 pang'ono.
