Urugero rw’Imvi Urugero rw’imvi, ruzwi kandi nk’urugero rw’ibara canke urugero rw’imvi, rwerekeza ku gukayangana kw’ibara. Ku buhinga bwo kwerekana amabara, ibara ry’umweru ni ryo rigena umubare w’amabara yerekanwa. Muri rusangi, uko urugero rw’ibara ry’umuhondo rugenda rurakura, ni ko amabara yerekanwa arushiriza kuba menshi, ni ko ishusho irushiriza kuba nziza, kandi ni ko vyoroha guserura ibintu vyiza cane. Urugero rw’ibara ry’umuhondo ahanini ruvana n’umubare w’ibice vy’uguhindura A/D kwa sisitemu. Ego ni ko, igikoresho co gukora amasanamu, ubuhinga bwo kwibuka be n’ubuhinga bwo gutanga amakuru bitegerezwa gutanga umubare w’ibice bihuye n’ivyo kugira ngo bifashe. Ivyerekana amatara yo mu rugo ahanini bikoresha uburyo bwo gukora 8-bit, ni ukuvuga ingero 256 (28) z’ibara ry’umuhondo. Mu mvugo yoroshe, hariho uburyo 256 bwo gukayangana kuva ku mwirabura gushika ku mweru. Hakoreshejwe amabara atatu y’intango ya RGB, amabara 256×256×256=16.777.216 arashobora gukorwa. Ni ukuvuga amabara azwi cane ko ari 16 megacolors. Ivyerekana ibimenyetso mpuzamakungu bikoresha cane cane uburyo bwo gukora amabara 10, bisobanura ingero 1024 z’ibara ry’umuhondo, bikaba vyemerera amabara y’intango ya RGB guhingura amabara miliyaridi 1,07.
Naho ibara ry’umweru ari ikintu gihambaye mu kumenya igitigiri c’amabara, si ikibazo c’uko uko amabara ari menshi ni ko ari vyiza. Ica mbere, ubushobozi bw’ijisho ry’umuntu bwo kubona ibintu burafise aho bugarukira. Ica kabiri, kwongerera umubare w’ibice mu burebure bwo gukora amasanamu birimwo amahinduka mu mice itandukanye yo gukora amasanamu, kubika, gutanga, no gucapura, ivyo bikaba bituma habaho kwongerera cane ibiciro kandi bikagabanya ubushobozi bw’ibiciro-. Muri rusangi, ibintu vy'abaguzi canke vy'ubudandaji birashobora gukoresha uburyo bwa 8-bit, mu gihe ibintu vy'urugero rwo gutangaza bishobora gukoresha uburyo bwa 10-bit.
Ingero z’Ivangura ry’Umuco: Ingero z’ivangura ry’umuco zivuga urutonde rw’ingero z’umuco mu gishushanyo ijisho ry’umuntu rishobora gutandukanya, kuva ku ry’umwiza gushika ku ry’umuco. Nk’uko twabibonye, ibimenyetso bimwebimwe birafise urugero rwo hejuru cane rw’ibara ry’umuhondo, bishika ku rugero rwa 256 canke mbere 1024. Ariko rero, kubera ko ijisho ry’umuntu ridashobora gutahura neza umuco, izo nzira z’ibara ry’umuhondo ntizishobora gutandukanywa bimwe bishitse. Mu yandi majambo, ivyicaro vyinshi vy’ibara ry’imvi biri hafi bishobora gusa n’ivyo nyene ku jisho ry’umuntu. Vyongeye, ubushobozi umuntu abona buratandukanye. Ku bijanye n’ibintu vyerekanwa, uko ijisho ry’umuntu rishobora gutandukanya ingero z’ibara ry’umuhondo ryinshi, ni ko bigenda neza, kubera ko ishusho yerekanwa amaherezo ari iyo umuntu abona. Uko ijisho ry’umuntu rishobora gutandukanya urugero rw’umuco, ni ko n’aho ibara ry’ikigaragaza rirushiriza kuba rinini, kandi ni ko n’ubushobozi bwaryo bwo kwerekana amabara menshi buba bwinshi. Ingero z’ivangura ry’umuco zirashobora kugeragezwa hakoreshejwe porogarama zidasanzwe; muri rusangi, igicapo c’iyerekanwa gishika ku rwego 20 canke birenze kibonwa ko gifise urugero rwiza.
Ihinduka ry'umurongo w'ibara ry'imvi: Ihinduka ry'ibara ry'imvi ritari - ry'umurongo ryerekeye guhindura amakuru y'ibara ry'imvi hakurikijwe amakuru y'ivyashikiye canke ubucuti bumwe bumwe bw'imibare butagira umurongo imbere yo kuyatanga ku mugaragaro. Kubera ko ama LED ari ibikoresho vy’umurongo, ibiranga iyerekanwa ryavyo biratandukanye n’ibiranga iyerekanwa ritagira umurongo ry’ibikoresho vy’igenzura vya kera. Kugira ngo umenye neza ko ingaruka y’iyerekanwa ry’amatara y’izuba ihuye n’inkomoko y’amakuru ya kera ata gutakaza ingero z’ibara ry’umweru, uguhindura amakuru y’ibara ry’umweru kutagira umurongo -gukorwa muri rusangi mu ntambwe za nyuma z’uburyo bwo kwerekana ibara ry’umweru. Umubare w'ibice mu makuru yahinduwe uragwira (kugira ngo ntihagire amakuru y'ibara ry'umuhondo atakarira). 4096-urugero canke 16384-urugero rw'imvi canke rwo hejuru ruvugwa n'abaguzi bamwebamwe b'ubugenzuzi bwo mu rugo rwerekeza ku bunini bw'umwanya w'imvi inyuma y'urugero rutari -rw'uguhindura. 4096urugero rukoresha ubuhinga bwa 8-guhindura umurongo-2-bit source 16384 ingero zikoresha 8-bit kugeza kuri 16-bit ubuhinga bwo guhindura butagira umurongo. Ihinduka ritari ry'umurongo rikoresheje inkomoko y'ibice 8 rizotuma ata gukeka haba umwanya munini w'ibara ry'umuhondo kuruta inkomoko y'ibice 8. Muri rusangi, bikwiye kuba nibura ibice 10. Kimwe n'ibara ry'imvi, iyi parametere si ngombwa ko iba nziza uko iba nini; 12 bits ni kenshi bihagije ku mpinduka nyinshi.
