Chigamulochi chimalongosola chiwerengero cha madontho, kapena pixelisi, chomwe chithunzi chili ndi kapena chingawonetsedwe pa makompyuta, TV, kapena chipangizo china chowonetsera. Machaputala awa ali mu zikwi kapena mamiliyoni, ndipo kumveka kukuwonjezeka ndi chisankho.
Kutsimikizika mu Oonera Ma kompyuta
Chisankho cha pulogalamu ya makompyuta chimatanthauzira kuchuluka kwa madontho awa omwe chipangizochi chikhoza kuwonetsera. Zimafotokozedwa ngati chiwerengero cha madontho osakanizidwa ndi chiwerengero cha madontho owoneka; Mwachitsanzo, chisankho cha 800 × 600 chikutanthauza kuti chipangizochi chingasonyeze madontho 800 kudutsa madontho 600 pansi-choncho, kuti madontho 480,000 awonedwe pawindo.
Pofika m'chaka cha 2017, makompyuta ambiri omwe amagwiritsa ntchito makompyutawa akuphatikizapo:
- 1366 x 768
- 1600 x 900
- 1920 x 1080
- 2560 x 1440
- 3840 x 2160
Kutsimikiza mu TV
Kwa ma televizioni, kuthetsa ndi kosiyana kwambiri. Mtengo wa chithunzi cha TV umadalira kwambiri kuchuluka kwa pixel kusiyana ndi kuchuluka kwa pixelisi. Mwa kuyankhula kwina, chiwerengero cha ma pixels pa unit of area chimaimira khalidwe la chithunzi, osati chiwerengero cha pixel. Motero, chisankho cha TV chikufotokozedwa mu pixels per inch (PPI kapena P). Pofika m'chaka cha 2017, malingaliro ambiri a TV ndi 720p, 1080p, ndi 2160p, zonse zomwe zimatengedwa kutanthauzira kwakukulu.
Kusintha kwa Zithunzi
Chisankho cha fano lamagetsi (chithunzi, chithunzi, etc.) chikutanthauza chiwerengero cha pixels zomwe zili ndi, zomwe zimawonetsedwa ngati ma pixel mamiliyoni (megapixels, kapena MP). Chigwirizano chachikulu, khalidwe labwino kwambiri. Mofanana ndi oyang'anira kompyuta, chiyerocho chimafotokozedwa ngati m'lifupi ndi kutalika, kuwonjezeka kuti chibweretse chiwerengero cha mayina a megapixels. Mwachitsanzo, chithunzi chomwe chili ndi pixel 2048 pozungulira 1536 pixels (2048 x 1536) chili ndi pixel 3,145,728; m'mawu ena, ndijambula 3.1-megapixel (3MP).
Mtsinje
Mfundo yofunika: Kaya mukuwongolera makompyuta, ma TV, kapena mafano, chiganizo ndizowunikira momveka bwino, momveka bwino, ndi kuyeretsa kwa chiwonetsero kapena fano.
