Porojekita ni igikoresho cyo kwerekana amashusho cyangwa amashusho ku buso burambuye nka ecran cyangwa inkuta hakoreshejwe amahame y'urumuri.

Projekteri ni igikoresho cyo kwerekana amashusho cyangwa amashusho ku buso burambuye nka ecran cyangwa inkuta hakoreshejwe amahame y'urumuri. Inshingano yacyo y'ingenzi ni ukwagura amashusho kugira ngo abantu benshi bayabone cyangwa kuyatanga mu buryo bunini bwo kureba amashusho. Yakira ibimenyetso bivuye ku bikoresho nka mudasobwa, telefoni zigendanwa,TVudusanduku, na disiki za USB, kandi binyuze mu bufatanye bw'amasoko y'urumuri rw'imbere, lenseri, na modules zo gutunganya amashusho, bitanga amashusho. Ingano y'icyerekezo ishobora guhindurwa hakurikijwe intera n'ibipimo bya lenseri, kuva kuri santimetero mirongo kugeza kuri santimetero zirenga ijana, bigatuma yoroha mu buryo butandukanye bwo kuyikoresha.

Ibice by'ingenzi bya porojekita birimo isoko y'urumuri (amatara ya halogen mu minsi ya mbere, ubu ahanini amatara ya LED n'amatara ya laser), chip yo gufata amashusho (nka LCD, DLP, cyangwa LCoS chips), lens, n'icyuma gitunganya ibimenyetso. Dukurikije uko ikoreshwa, ishobora kugabanywamo porojekita zo mu rugo (zikwiriye kureba filime no gukina), porojekita z'ubucuruzi (zikoreshwa mu biganiro n'amahugurwa mu nama), porojekita z'uburezi (zikoreshwa mu kwigisha mu ishuri, zishimangira urumuri n'ituze), na porojekita z'ubuhanga (zikoreshwa ahantu hanini no hanze, zifite urumuri rwinshi cyane kandi zikoresha ikigereranyo kinini cyo kujugunya).

Ibyiza byayo biri mu buryo bworoshye gutwara (imwe mu nzu n'ubucuruzi ni nto kandi byoroshye gutwara), ikoreshwa ry'umwanya munini (nta mpamvu yo gufata umwanya uhamye wo ku nkuta, yemerera kugenda neza), kandi ihendutse ku buryo bworoshye gukoresha ecran nini ugereranije na televiziyo zingana. Byongeye kandi, porojekiteri nyinshi zishyigikira imirimo nko gukosora inkingi, kwibanda ku buryo bwikora, no kugenzura ijwi mu buryo bw'ubwenge kugira ngo byorohere gukora. Hamwe n'iterambere ry'ikoranabuhanga, urumuri, ubushobozi bwo kwerekana (4K byahindutse ikintu gikuru), kandi itandukaniro rya porojekiteri ryakomeje gutera imbere, bituma amashusho agaragara neza ndetse no mu bidukikije bifite urumuri rwinshi. Yabaye igikoresho cy'ingenzi mu myidagaduro yo mu rugo, ubufatanye mu biro, no mu burezi no mu mahugurwa.
