DPI - yog dab tsi? Yuav ua li cas rau configure cov DPI

Txog ntau yam acronyms thiab obscure kev cov ntsiab lus uas. DPI - uas yog? Qhov no yuav txo tau ntawm lub zoo-paub designer, computer science, cov neeg uas ib zaug ua hauj lwm nrog rau cov duab. Qhov no yog ib lub sij hawm hnov thiab gamers nrog lawv txias feature tso. Tam sim no peb yuav ua tiag mus nrog no tsiaj.

xaiv

Yog hais tias koj thov kom lub hauv internet txog DPI, uas yog, thiab qhov uas siv tau, koj yuav tau txais ob peb cov lus teb. Tom qab tag nrho, nws muaj peb decryption ntawm abbreviations:

• Sib sib zog nqus pob ntawv soj ntsuam - muab kev pab ib lub cuab tam uas sau statistics, khij lub lim network packets thiab lawv txheem.
• Discounted profitability Index - yog ib qho nyiaj txiag lub sij hawm uas yog lub luag hauj lwm rau cov rov qab rau lub peev.
• Dots ib nti - nrog English translation li "dots ib nti".

Hais tias kev xaiv kawg nkaus peb yuav xav txog.

daim ntawv tso cai

Yog hais tias peb tham hais txog qhov DPI, nws yuav paub tseeb hais tias nws yog ib chav tsev ntawm kev ntsuas. Tab sis zoo li cas? Nws hloov tawm mus rau kawm duab daws teeb meem thiab siv no tsiaj.

Daws teeb meem rau nws tus kheej - ib tug qhia uas qhia tus naj npawb ntawm cov dots (pixels) ib chav tsev cheeb tsam. Feem ntau cov feem ntau, qhov no Performance index yog muaj feem xyuam rau lub hom digital dluab, tab sis nws yog siv nyob rau hauv lub Granulation photographic films, cov ntaub ntawv thiab thiaj li nyob. N.

Yog li ntawd, yog tias koj yuav tsum txuag cov ntaub ntawv nyob rau hauv cov duab cov ntaub ntawv nrog koj yam loj thiab coj nws tag nrho rau sau, ces feem ntau yuav, DPI yuav tuaj mus rau cawm. Qhov no tus nqi qhia tus xov tooj ntawm dots ib nti. Yog hais tias koj muaj ib tug 300 dpi, ntsig txog, nws yog sib npaug zos rau 300 dots ib nti.

Piv txwv li

Lwm cov piv txwv, kom to taub yuav ua li cas no tus nqi ua hauj lwm. Piv txwv rau koj cov duab muaj ib tug daws teeb meem ntawm 350 dpi. Koj yuav tsum xa mus rau tus ntawv loj ntawm 10 los ntawm 10 cm. Txhais mus rau hauv lub nti koj tau txais ib 3.9 x 3.9 nti. Yuav kom to taub li cas yuav tsum tau qhov luaj li cas ntawm thawj daim duab yuav tsum tau 3.9 multiplied by 300. Yog li ntawd peb tau txais 1170 x 1170 pixels. Nrog rau qhov no Performance index cov duab zoo yog siv tau.

daim ntawv thov

Tam sim no ntau txog qhov twg thiab yuav ua li cas thov DPI. Hais tias yog, peb twb dealt nrog. Tus nqi no yog siv los qhia kom meej rau kev daws teeb meem. Lub Xeem, Lub peb xav tau tus derivation duab cov ntaub ntawv nyob rau hauv ib tug ca them nyiaj yug.

Qhov no tus nqi koj yuav nrhiav tau nyob rau hauv lub specifications ntawm lub tshuab luam ntawv. 600 tej zaum yuav qhia los ntawm 450 dpi. Yog li ntawd nws yog tseeb hais tias tus ntaus ntawv yog muab tej txiaj ntsim nrog ib tug daws teeb meem ntawm uas yog 600 kab rov tav dots thiab 450 ntsug tsuas me me. Nyob rau hauv no qhov chaw ntawm lub square coj lub 1 los ntawm 1 inch.

Yog hais tias peb tham txog cov tshuab luam ntawv, feem ntau nws yog no daim duab no piv rau lub PPI. Cov ob qhov tseem ceeb sawv cev rau ib yam khoom. Siv yog hais tias koj xav mus sib tov cov xim yuav tsum tau luam. Ces 1 yuav sib npaug zos rau 1 dpi ppi. Yog hais tias tus ntaus ntawv yuav tsum tau tsis sib tov number case, qhov no mis yuav zoo sib txawv. Nws yuav siv lub Performance index N, uas qhia rau hauv lub xov tooj ntawm cov xim siv rau printing. Ces dpi ppi sib npaug khoo los ntawm cov xov tooj uas yog nyob rau hauv lub Performance index N.

Qhov no xam yog lub ntsiab kom zoo dua ntawm inkjet printers. Tsis zoo li fotomashin, stringed li muaj loj index nqi sib npaug zos rau cov nqi ntawm DPI PPI. Raws li muab ntsiab lus ntau ntxiv kom dhau rau ib tug pixel.

lwm yam kev ntsuas

DPI duab - tsis yog tus nqi ntawm cov kev tso cai. Raws li peb tau kawm, muaj ib tug kev sib raug zoo nrog lwm yam zoo xws ntsuas. Yog li, nyob rau hauv printers raster point yog sawv cev los ntawm ib tug plurality ntawm me me tsuas me me. Lawv hu ua flash. Tus nab npawb ntawm xws flashes ib nti thiab txhais DPI. Tus nab npawb ntawm raster ntsiab lus uas muab zais rau hauv no mas ib tug nti denote PPI. Raws li, yog hais tias tus piv ntawm ob indices yog ntau dua cov duab zoo.

Muaj yog ib tug ntau qhia - yog LPI. Tus nqi qhia tus xov tooj ntawm cov kab ib nti. Qhov no daws teeb meem qhia txog cov lag luam ntawm lub laser tshuab luam ntawv. Nti nyob rau hauv cov ntaub ntawv no yog sawv cev tsis los ntawm ib tug taw tes, raws li ua ntej, tab sis kab. Qhov ntawd yog, yuav tsum tau ntau leej nyob rau hauv lub formulation, lub LPI - yog tus naj npawb ntawm kab ib linear nti.

Lwm tus nqi yog sawv cev los ntawm lub acronym SPI. Nws qhia tau hais tias cov xov tooj ntawm elementary me ntsis. Lub ntsuas no yog qhov heev nyuab thiab tsis yog li ntawd feem ntau siv nyob rau hauv printing. Tab sis nyob rau hauv kev nws yog siv rau printing gradients. Thiab yog hais tias tus PPI hais txog thaum kawg, cov SPI - yog ib feem ntawm cov txheej txheem. Interestingly, nyob rau hauv kev ob leeg nuj nqis muaj tib lub ntsiab lus nyob rau hauv sib npaug zos tej yam kev mob.

gaming nas

Tab sis nws hloov tawm hais tias tsis yog txhua txhua cov ntaub ntawv hais txog lub DPI. Hais tias yog, peb to taub nyob rau hauv nqe lus dav dav. Yuav ua li cas siv kuj to taub. Tab sis peb tsis tau ib yam. Qhov tseeb hais tias tus nqi yog feem ntau pom nyob rau hauv lub ntim nrog gaming nas. Muab tau txais ua ntej ntaub ntawv los ntawm lub ntxias tsis yooj yim. Tab sis koj muaj peev xwm sim.

Lub fact tias cov dpi, xws li sawv zoo li, tab sis muaj ib tug me ntsis txawv to taub. Yuav kom leej, ib tug nas, qhov no daim duab yog zoo dua rau decipher li cov dots ntawm cursor montion ib nti. Hais tias yog, tus nqi ntawm cov zog ntawm tus cursor dpi. Tom ntej no mus uas tus nqi yog siv cpi. Nws roughly txhais tau tib yam, thiab nws yuav muaj kuab siv nws yog luv luv. Tab sis nyob rau hauv Feem ntau, thiab ib tug thiab lub thib ob nqi no yog lub xov tooj ntawm kis cov kauj ruam uas extends ntxias 1 inch.

Thiab nws yog tsim nyog los nkag siab hais tias peb yuav sib tham txog lub zog ntawm tus nas es tsis txhob ntawm tus cursor. Movement nyob rau hauv cov ntaub ntawv no yog txhais raws li ib tug ruam, ib kauj ruam zoo li lub teeb liab. Yog hais tias lub Performance index dpi siab, lub tsev tsiv ntseeg nkaws.

Marketing?

Qhov kev tshawb xav yog tias qhov no daim duab, uas quaj los ntawm advertising leaflets thiab ntim yog ntau tshaj ib tug li ploy. Qhov tseeb hais tias ob peb tus neeg paub, tab sis rau no heev ceev tsis tau hnov qab txog qhov chaw nres nkoj pov nqi. Nws yog lub npe hu hais tias tam sim no lub siab tshaj plaws nqi ntawm 1000 Hz. Koj yuav xav hais tias yog hais tias tus nas muaj dua ib tug thib ob 2 nti, ces qhov no daim duab yuav ob npaug. Nyob rau hauv qhov tseeb, nws hloov tawm hais tias tus ntoo khaub lig rau lub chaw pib ntawm 1000 Hz tseem yuav tsis ua hauj lwm. Yog li ntawd dab tsi yog qhov kom zoo dua ntawm cov nqi no nyob rau hauv lub keypad?

DPI - qhov no yog ib qho uas qhia hais tias kev hloov cov kev ceev ntawm lub cursor rau ntawm cov zaub. Thiab lub feem ntau zoo nws nyob rau hauv cov ntaub ntawv ntawm high-kev daws teeb meem cov ntxaij vab tshaus. Nws yog ib zajlus kom hais tias yog cov zaub loj, tus nas muaj mus ncig teb chaws ib tug deb xwm yeem mus rau kab pheeb ces kaum ntawm lub monitor. Yog li ntawd, tus nqi yog tsuas ib qho tseem ceeb rau cov players thiab cov neeg uas ua hauj lwm nrog graphics. Rau lawv, lub xam ntawm 1,600 dpi yog siv tau.

Rau lwm cov neeg siv, uas muaj me me thiab tshuaj ntsuam ntawm kev 1600x1200 yuav txaus, thiab 800 dpi. Qhov no tus nqi yog qhov nruab nrab rau hnub tim. Yog hais tias tus saib yog 1200x800, ces nws yuav tsum txaus thiab ib tug nas nrog ib tug daws teeb meem ntawm 400-500 dpi.

tshawb pom

Nws yuav paub tseeb hais tias DPI - ib tug nqi uas yog cov lus feem ntau designers, cov neeg uas ua hauj lwm nrog graphics thiab printing. Qhov no tso cai, uas tso cai rau los mus txiav txim tus naj npawb ntawm dots ib nti thaum displaying rau ib tug ca them nyiaj yug. Yog hais tias peb yuav sib tham hais txog ib tug nas, lub DPI nyob rau hauv cov ntaub ntawv no qhia tau hais tias lub zog ntawm tus nas dpi.

Yog hais tias koj muaj ib tug gamer nas, rau lo lus nug ntawm yuav ua li cas mus kho cov DPI, yuav tsum tsis txhob yuav, vim hais tias nws yog feem ntau yuav tau kho cov kev daws teeb meem nyob rau hauv lub rooj plaub yog ib tug tshwj xeeb khawm. Nyob rau hauv tej rooj plaub, koj muaj peev xwm kho thiab ntawm software. Yog hais tias koj muaj ib tug qub nas, tab sis koj xav kho nws ceev, nws yuav yuav txaus mus rau lub chaw rau cov PC thiab set lub slider rau lub Desired qib.
