Erekana Electronic Yerekana ifite pigiseli nziza, ntakibazo cyangwa ijoro, iminsi yimvura cyangwa imvura,Iyoboweirashobora kureka abumva kubona ibirimo, kugirango bahure nabantu basaba sisitemu yo kwerekana.
Ikoranabuhanga ryo kugura Ishusho
Ihame ryingenzi ryo kwerekana elegitoronike ni uguhindura ibimenyetso bya digitale mubimenyetso byerekana ibimenyetso hanyuma tukabishyikiriza muri sisitemu. Uburyo gakondo nugukoresha ikarita yo gufata amashusho hamwe nikarita ya VGA kugirango igere kumikorere yerekana. Imikorere nyamukuru yikarita yo kugura amashusho ni ugufata amashusho yerekana amashusho yumurongo, amanota yumurongo hamwe na Pixel hamwe na VGA, hanyuma ubone ibimenyetso bya digitale cyane cyane mugukoporora amabara. Mubisanzwe, software irashobora gukoreshwa mugihe cyo kwigana-nyaburanga cyangwa ubujura bwibikoresho, ugereranije nubujura bwibikoresho birakora neza. Ariko, uburyo gakondo bufite ikibazo cyo guhuza na VGA, kiganisha kumpande zituje, ireme ryiza ryishusho nibindi, kandi amaherezo, kandi amaherezo byangiza ishusho yerekana amashusho ya elegitoroniki yerekana amashusho ya elegitoroniki yerekana amashusho ya elegitoroniki yerekana amashusho yerekana amashusho ya elegitoronike.
Dukurikije iyi mpuguke mu nganda zashizeho ikarita ya videwo yeguriwe JMC, ihame ry'ikarita rishingiye ku muvuduko wa PRA na VGA Icya kabiri, kubona ibyemezo byemejwe muburyo bwuzuye bwo kwemeza imiterere yuzuye ya videwo, igice cyimpande ntikiri fuzzy, kandi ishusho irashobora gupimwa no kwipimisha ikangukwa no kwimuka kugirango duhuze ibisabwa. Hanyuma, amabara atatu yumutuku, icyatsi nubururu birashobora gutandukana neza kugirango duhuze ibisabwa nibara rya elegitoroniki yerekana electronic yerekana ecran ya elegitoroniki.
2. Ishusho Yukuri Ibara
Ihame ryibitabo byuzuye-ibara risa nubwa televiziyo mubijyanye n'imikorere igaragara. Binyuze muburyo bwiza bwo guhuza amabara atukura, icyatsi namabara yubururu, amabara atandukanye yishusho arashobora kugarurwa no kubyara. Isuku y'amabara atatu umutuku, icyatsi nubururu bizagira ingaruka muburyo bwo kubyara ibara ryishusho. Twabibutsa ko kubyara ishusho atari ihuriro ridasanzwe ryamabara atukura, icyatsi n'amabara yubururu, ariko harasabwa ikiremwa runaka.
Ubwa mbere, igipimo cyurumuri rwumutuku, icyatsi nubururu bigomba kuba hafi ya 3: 6: 1; Icya kabiri, ugereranije nandi mabara abiri, abantu bafite ubukana runaka kumutuku mubyerekezo, birakenewe rero gukwirakwiza umutuku mumwanya werekana. Icya gatatu, kubera ko abantu icyerekezo cyabantu bitabira umurongo udasanzwe wumucyo, icyatsi nubururu, birakenewe gukosora urumuri rwasohotse imbere ya TV kurumuri wera hamwe nuburemere butandukanye. Icya kane, abantu batandukanye bafite ubushobozi bwo gukemura amabara butandukanye mubihe bitandukanye, birakenewe rero kumenya ibimenyetso bifatika byororoka amabara yororoka amabara, muri rusange nkibi bikurikira:
(1) uburebure bwamabuye yumutuku, icyatsi nubururu byari 660nm, 525nm na 470nm;
.
(3) urwego rwimbuto rwamabara atatu yibanze ni 256;
(4) Gukosorwa kudakurikiza umurongo bigomba kwemezwa gutunganya pigiseli.
Sisitemu yo kugabanuka gutukura, icyatsi nubururu burashobora kugerwaho na sisitemu yimyanya cyangwa na software ya sisitemu yo gukina.
3. Umuzunguruko udasanzwe
Hariho uburyo bwinshi bwo gushyira pigiseli ubu: (1) umushoferi; (2) dc disiki; (3) Inkomoko ihoraho. Ukurikije ibisabwa bitandukanye bya ecran, uburyo bwo gusikana buratandukanye. Kuri Musoor Guhagarika ecran, uburyo bwo gusikana bukoreshwa cyane. Kuri ecran ya pigiseli
Iyobowe kare ryakoreshejwe cyane cyane kuri voltage yamashusho hamwe nuburyo bwo guhindura, ubu buryo bufite amakuru yumucuruzi menshi, kwizerwa cyane hamwe nibindi bidahuje, iyi ngingo idahuye nizindi terambere ryerekanwe mugihe runaka. Kugirango ukemure amakosa yavuzwe haruguru ya Erekana Electronike, Isosiyete yo muri Amerika yateje imbere ishyirwa mu bikorwa rya porogaramu, cyangwa asic, rishobora kuba riri mu masomo yo gutwara ibi bikurikira: Gutwara ibiruhuko birimo, bigatuma habaho ubushobozi bwo gutwara, hashobora gusubizwa muri iyo ngabo. Ibinini binini kandi voltage, intera nini, muri rusange birashobora kuba hagati ya 5-15V Guhitamo byoroshye; Urukurikirane rwabakurikira-rusarure ruri runini, insakoro ya none hamwe ni ukurenga kuri 4ma; Umuvuduko wihuse wamakuru, akwiriye kurubuga rwinshi-gray yayoboye imikorere yumushoferi.
4. Umucyo ugenzura D / T Ikoranabuhanga ryo Guhindura
Yerekanye yerekana ko elegitoronike igizwe na pigiseli nyinshi zigenga na gahunda no guhuza. Ukurikije ikintu cyo gutandukanya pigiseli kuri mugenzi wawe, byerekana ko elegitoronike yerekana gusa ishobora kwagura uburyo bwo kugenzura igenzura ryayo binyuze mubimenyetso bya digitale. Iyo pigiseli imurikirwa, leta yayo iragenzurwa ahanini numugenzuzi, kandi itwarwa yigenga. Iyo videwo igomba gutangwa mubara, bivuze ko umucyo n'amabara ya buri pigiseli akeneye kugenzurwa neza, kandi imikorere yo gusikana irasabwa kuzuzwa mugihe cyagenwe.
Ibitekerezo binini bya elegitoronike bigizwe nibihumbi byibihumbi bya pigiseli, byongera cyane ibintu bigoye muburyo bwo kugenzura ibara, bityo bisabwa gusa kugirango ushyireho amakuru. Ntabwo bifatika gushiraho d / a kuri buri pigiseli muburyo bwo kugenzura nyirizina, ni ngombwa rero kubona gahunda ishobora kugenzura neza sisitemu igoye pigiseli.
Mugusesengura ihame ryiyerekwa, urasanga ko impuzandengo ya pigiseli ahanini biterwa nigipimo cyacyo cyiza. Niba igipimo cya Bright-Off gihinduwe neza kuriyi ngingo, kugenzura neza umucyo birashobora kugerwaho. Gushyira mu bikorwa iri hame kugirango uhindure uburyo bwa elegitoronike bisobanura guhindura ibimenyetso bya digitale mugihe ibimenyetso, ni ukuvuga guhinduka hagati ya D / A.
5. Kwiyubaka amakuru no kubika tekinoroji
Kugeza ubu, hariho uburyo bubiri bwo gutegura amatsinda yo kwibuka. Imwe ni uburyo bwa pigiseli ya pigiseli, ni ukuvuga ingingo zose za pigiseli ku ishusho ibitswe mumubiri umwe wibuka; Ubundi nuburyo bwindege but, ni ukuvuga ingingo zose za pigiseli ku ishusho ibitswe mumibiri itandukanye yo kwibuka. Ingaruka zitaziguye zo gukoresha ubwinshi bwumubiri nukumenya ibintu bitandukanye bya Pixel icyarimwe. Mubijyanye n'imiterere ibiri yo kubika haruguru, uburyo bwindege but bufite ibyiza byinshi, nibyiza mugutezimbere ingaruka zo kwerekana ziyobowe na ecran. Binyuze mu kubaka amakuru kugirango ugere ku guhindura amakuru ya RGB, uburemere bumwe hamwe na pigiseli zitandukanye zirahuzwa mu buryo busanzwe kandi gishyirwa muburyo bubikwa.
6. Ikoranabuhanga rya ISP mububiko bwumuzunguruko
Ububiko bwa elegitoronike buke bwerekana ko kugenzura umuhanda byateguwe ahanini numuzunguruko usanzwe wa digitale, muri rusange igenzurwa numuzunguruko wumuzunguruko. Mu ikoranabuhanga gakondo, nyuma yo gushushanya umuzunguruko igice cyarangiye, ikigo cy'akarere kigizwe mbere, kandi ibice bifatika byashyizweho kandi ingaruka zirahinduka. Iyo imikorere yumuzenguruko ibikorwa idashobora kuzuza ibyifuzo nyabyo, bigomba gukorwa kugeza byujuje ingaruka. Birashobora kugaragara ko uburyo bwa gakondo bufite urwego runaka rwibihe rwose, ahubwo binafite uruziga rurerure, rugira ingaruka ku iterambere ryiza ryibikorwa bitandukanye. Iyo ibice binaniwe, kubungabunga biragoye kandi ikiguzi ni kinini.
Aha hashingiwe, sisitemu ya sisitemu ya gahunda (ISP) yagaragaye, abakoresha barashobora kugira imikorere yo guhindura inshuro nyinshi ibishushanyo mbonera hamwe na gahunda ya porogaramu ya software kuri gahunda ya seriveri, sisitemu ya digitale ishingiye kuri sisitemu ya sisitemu. Hamwe no gutangiza sisitemu ya sisitemu yo guterimo porogaramu, ariko kandi ikoreshwa ryibigize iraguka cyane, kubungabunga umurima kandi ibikoresho byibikoresho byoroshe. Ikintu cyingenzi cya sisitemu tekinoroji ya sisitemu ni uko bidakenewe gusuzuma niba igikoresho cyatoranijwe gifite imbaraga mugihe ukoresheje software ya sisitemu yo kwinjiza logique. Mugihe cyinjiza, ibice birashobora gutoranywa kubushake, ndetse nibice bihuye birashobora gutorwa. Nyuma yinjiza irangiye, guhuza n'imihindagurikire y'ikirere birashobora gukorwa.
