RGB - chii chakakosha kuziva?

Iwo mafungu emagetsi emagetsi ari pakati pe380 kusvika 780 nanometers ane tsananguro dzakawanda dzemasvomhu muchimiro chenzvimbo yemavara matatu-dimensional. Izvi zvakakosha nekuti ziso remunhu riri kushanda pano. Munyaya yekugadzira mavara pamasikirini uye monitors, iyo RGB system inoshandiswa.

Chii chinonzi RGB modhi?

RGB - imwe yemhando huru yemuvara wenzvimbo ine hukama nechiedza chinooneka, nekuda kwemavara anogona kurekodhwa pamhando dzese dzemwenje-emitting zvishandiso.

Iro zita pacharo chidimbu chemavara ekutanga emavara matatu muChirungu:

• R mutsvuku zvinoreva tsvuku
• G - girini, i.e. girinhi
• B - bhuruu, zvinoreva bhuruu

Iyo sisitimu ndiyo mhedzisiro yekuona kwakananga kweruvara neziso remunhu. Chokwadi ndechekuti mavara ese anonzwisiswa neziso anogona kumiririrwa nemazvo semugumisiro wekusanganisa kuyerera kwechiedza muzvikamu zvakafanira mumavara matatu aya. Iyo RGB yekurekodha nzira inonyanya kushandiswa kumidziyo yemazuva ano yekufungidzira, i.e. monitors, LCD skrini, smartphone uye piritsi skrini, uye mapurojekita. Inoshandawo zvakanaka pamidziyo yekuona semakamera edhijitari uye scanner, pamwe nesainzi yekombuta, sezvo pendi yemavara emafaira mazhinji yakanyorwa muRGB se24-bit notation - 8 bits pachikamu chimwe nechimwe.

Ko mavara anoburitswa sei muRGB system?

Kuti uwane zvikamu zvemavara muRGB, imwe nzira yekuwedzera synthesis inoshandiswa, iyo inosanganisira kugadzira mavara ega ega nekusanganisa mwenje wemwenje neakanyatsosarudzwa intensity. Nekuda kweizvozvo, mifananidzo ine mavara-akawanda inoonekwa pane monitors kana zvimwe zvishandiso zvataurwa pamusoro apa. Nemamwe mashoko, kana maranzi echiedza chemavara matatu ekutanga akawira pamusoro pechidzitiro, anongoerekana agadzira mavara matsva anotorwa neziso remunhu, akaiswa pamusoro peumwe neumwe. Izvi zvinokonzerwa nemhando chaiyo yeziso, iyo isingakwanisi kusiyanisa pakati pezvikamu zvega, asi inozviona pamwe chete, semuvara mutsva. Mwaranzi yechiedza kubva pachiratidziro inoenda zvakananga mumaziso uye haina kuratidzwa kubva kune chero chinhu munzira.

Kuwedzerwa kwezvimwe zvikamu mukuwedzera synthesis kunoitika pane dema kumashure, nekuti izvi ndizvo zvakaita mamonitor. Izvi zvakasiyana chaizvo pane iyo CMYK color palette, umo kumashure kune chena ruvara rwebepa uye rinoiswa pariri nekufukidza zvikamu uchishandisa nzira yehalftone. Iyo RGB modhi inopa mikana yakawanda, asi yeuka kuti zvishandiso zvinoshandiswa ndizvo zvakakosha pakubereka kwemavara. Mumwe nemumwe wavo anogona kuve neakasiyana spectral maitiro uye saka mutsauko mukuonekwa kwemavara zvichienderana nechidzitiro icho maziso ari pairi.

Nzira yekuwana sei ruvara rwakasiyana?

Zvakakosha kusimbisa kuti ruvara rwega rwega muRGB system inogona kuva nechero kukosha kubva pa0 kusvika ku255, i.e. kuratidza kupenya kwemamwe mavara. Kana chikamu chacho chaiswa ku 0, skrini haizokwanisa kupenya muvara iwoyo. Kukosha 255 ndiyo yakanyanya kupenya inogoneka. Kuti uwane yero, R uye G anofanira kunge ari 255 uye B anofanira kunge ari 0.

Kuti uwane mwenje chena muRGB, mavara akatarisana anofanirwa kusanganiswa pakunyanya kusimba, i.e. mavara ari kumativi akasiyana - R, G uye B anofanira saka ane kukosha kwe 255. Dema rinowanikwa pane zviduku zvishoma, i.e. 0. Z, zvakare, grey ruvara inoda kugovera kune chimwe nechimwe chikamu kukosha pakati pechiyero ichi, i.e. 128. Nokudaro, nekusanganisa kubudiswa kwemavara mavara, chero ruvara runogona kuratidzwa.

Sei tsvuku, girini uye bhuruu mavara anoshandiswa?

Nyaya iyi yakambokurukurwa zvishoma. Mushure mezvose, hazvina kuitika kuti mavara matatu aya anoshandiswa mumuenzaniso uyu, uye kwete mamwe. Zvese zvinotsamira pane chaiwo kugona kweziso remunhu. Iyo ine yakakosha photoreceptors yekuona, inosanganisira retinal neurons. Muchirevo chezvifungidziro izvi, macones anokonzera photopic vision, i.e., maonero eruvara muchiedza chakanaka, anonyanya kukosha. Kana chiedza chakanyanyisa, kunzwisiswa kwechiratidzo kunoderera nekuda kwekuzara kwepamusoro kweiyi neuroni nayo.

Saka, suppositories inotora chiedza chine mafungu akasiyana-siyana ewavelength, uye zvinoitika kuti kune mapoka matatu makuru e suppositories - rimwe nerimwe rawo rinoratidza kunzwisiswa kwakakosha kune chaiyo yavelength. Nekuda kweizvozvo, wavelengths akatenderedza 700 nm vane basa rekuona zvitsvuku, zvakatenderedza 530 nm zvinopa ratidziro yebhuruu mukuona, uye wavelengths ye420 nm inokonzera girinhi. Iyo yakapfuma yeruvara palette mhedzisiro yemaitiro ega ega emapoka e suppositories kune anooneka wavelengths echiedza.

Kana chiedza chikapinda zvakananga munhengo yechiratidzo uye chikasaratidzwa pane chero chinhu chiri munzira yacho, ipapo mamwe mavara anogona kuratidzwa zviri nyore, izvo zvinoitika pamamonitor, skrini, mapurojekita kana makamera. Basa rekuwedzera rataurwa pamusoro rinoshandiswa, iro rinosanganisira kuwedzera mavara ega kune yakasviba kumashure. Chiri chimwe chinhu apo ziso romunhu rinoona chiedza chakaratidzirwa. Mumamiriro ezvinhu akadaro, maonero eruvara anova mhedzisiro yekutorwa kwemafungu emagetsi ehumwe hurefu nechinhu. Muuropi hwomunhu, izvi zvinotungamirira pakuonekwa kwerimwe ruvara. Izvi zvinonyatsopesana nemusimboti wekuwedzera, apo mavara anobviswa kubva kune chena kumashure.

Iyo RGB color palette inoshandiswa sei?

RGB inonyanya kukosha mumamiriro ezvinhu ane chokuita nemunda weInternet marketing. Chokutanga pane zvose, tiri kutaura nezvekugadzira webhusaiti yekugadzira purojekiti uye mamwe mabasa ose paInternet ane chokuita nekuwedzera mapikicha nemifananidzo kune zvakadhindwa zvinyorwa (somuenzaniso, pamagariro evanhu), pamwe nekugadzira mifananidzo kana infographics. Pasina ruzivo rwakakwana rwekugadzira mavara muRGB modhi, zvingave zvakaoma kuwana zvakakwana zvinogutsa mhedzisiro, kunyanya sezvo yega yega graphic inotaridzika zvishoma pane yega yega michina yemagetsi. Kunyangwe kushanduka kuri nyore mukupenya kwechidzitiro kunokonzera maonero akasiyana emavara (izvo zvinokonzerwa nekunzwa kwemakoni).

Zvakakosha kuyeuka kuti zvigadziriso zvekutarisa zvinokanganisa maonero emavara uye nekudaro dzimwe nguva misiyano mikuru mumumvuri. Ruzivo urwu zvirokwazvo runodzivirira kusanzwisisana kwakawanda pamwe nemutsara wemifananidzo uye vatengi. Ndosaka zvakakosha kuti uone purojekiti chaiyo pane angangoita mamonitor akati wandei. Ipapo zviri nyore kunzwisisa izvo vateereri vanoona. Ikoko hakuzovi nechinetso chokuti, mushure mekubvumirwa, purojekiti ichazviratidza pachayo zvakasiyana, nokuti mutengi akangoerekana achinja zvirongwa zvekucherechedza.

Imwe nzira yekubuda mumamiriro ezvinhu ndeyekushanda nemugadziri wemifananidzo ane dhizaini yemhando inobvumidza iwe kunyatso kuratidza mavara maererano nekubuda paramita. Panguva imwecheteyo, inofanira kusimbiswa kuti munyaya yezvigadzirwa zvakadhindwa, zvinetso zvakadaro hazvimuki. Zvakakwana kugadzirira kudhinda bvunzo pachine nguva kuti uone kuti kudhinda kwese kuchaita sei.
