Cov Duab Cov Qauv Ntsuam Xyuas thiab Kev Ntsuam Xyuas Kev Ntsuam Xyuas
Nrog rau kev nce qib ntawm digital technology, cov hauj lwm ntawm kev lag luam luam hauv kev tau txais cov duab tau raug tag nrho digitized. Vim yog qhov tseeb uas yog cov duab pom hauv lub cev xws li zaj duab xis thiab zaj duab xis yog kim, nqaim hauv daim ntawv thov, thiab qis hauv kev muag khoom, cov tuam txhab tsis muaj tswv yim coj tus cwj pwm zoo thiab cov ntaub ntawv loj loj. Xwb, lawv yog cov khoos kas thiab pheej yig cov koob yees duab. Kev ua ke ntawm digital rov qab thiab theem nrab vaj huam sib luag scanners ntau yoog raws thiab siv rau hauv kev siv tswv yim hauv kev lag luam luam.
Peb yog ib lub lag luam loj hauv Shenzhen Tuam Tshoj. Peb muab txhua phau ntawv nthuav tawm, cov duab thaij duab, cov duab kos duab, cov tsiaj ntawv, lub thawv ntawv, daim ntawv qhia hnub, txhua yam ntawm PVC, cov khoom ntawv, ntawv sau, Cov menyuam phau ntawv, cov ntawv nplaum, txhua yam ntawv tshwj xeeb xim xim luam ntawv, daim card cardand li.

Nyob rau hauv hnub no lub xov tooj txawb, cov koob yees duab nrog ntau lab ntawm pixels pib nkag mus rau lub billion-pixel era. Cov kev yees duab yuav tsis ntseeg tias yog lub hauv paus. Qhov zoo ntawm digital imaging txiav txim seb qhov zoo ntawm daim luam cov duab luam los ntawm lub hauv paus. . Kev paub ntawm cov duab digital thiab cov txheej txheem replication yog nyob rau hauv qhov tseem ceeb ntawm kev tsim cov qauv kom zoo ntawm cov luam cov duab tau raug tswj, ntsuas thiab ntsuas.
Txoj kev ntsuam xyuas duab zoo
Qhov kev luj xyuas ntawm qhov zoo tshaj plaws ntawm cov ntawv luam tawm yog qhov kev tshuaj ntsuam xyuas tus qauv rau qhov zoo ntawm kev luam ntawv. Cov kev tshuaj ntsuam xyuas rau cov duab zoo li cas yog los ntawm txoj kev ntsuas tus qauv thiab muab los ntawm lub hom phiaj kev ntsuam xyuas. Lub tswv yim tseem ceeb ntawm qhov kev ntsuam xyuas tus kheej yog pom tau los ntawm kev soj ntsuam ib puag ncig ntawm cov teeb pom kev zoo; lub hom phiaj kev ntsuam xyuas lub hom phiaj yog siv cov ntaub ntawv pab ntsuas cov ntaub ntawv, thiab lub hom phiaj kev ntsuam xyuas lub hom phiaj rau kev tswj kev lag luam hauv kev luam ntau yog muab faib ua peb hom:
1. Kev sib nraus. CMYK qhov tseem ceeb yog nyeem siv Konica Minolta FD-7 Densitometer los sis X-Rite pes densitometer. Cov xim ntawm cov ntsiab lus hauv cov qauv hauv cov qauv ntaub ntawv sau tseg, thiab cov ntaub ntawv khaws tseg rau hauv cov ntaub ntawv rau cov zauv los ntawm cov zauv, kev sib tw, thiab tw.
2. Spectrophotometry. Siv X-Rite XRite intellitrax los yog Konica Minolta FD-9 thiab lwm yam khoom siv rau kev nyeem ntawv tsis zoo nyeem nyeem cov ntawv Lab, cov qhab nia ntsuas zauv. Tus Intellitrax muaj kev ntsuas loj tshaj thiab tsis tua cov qauv kuaj, tab sis FD-9 muaj ib hom ntawv me me.
3. Kev tshawb nrhiav hauv internet (duab hom). Lub koob yees duab CCD txeeb cov duab thiab tshuaj xyuas qhov RGB xim qhov tseem ceeb ntawm cov ntawv sau thaiv los txiav txim thiab tshuaj xyuas nws. Txoj kev no yog siv los txhim kho cov teeb meem zoo nyob rau hauv cov txheej txheem. Vim tias qhov kev ntsuas ntsuas thiab cov software ua haujlwm tau zoo nyob rau hauv lub xeev, nws muaj kev ntseeg ntau dua li kev paub tseeb.
Vim tias txoj cai chromaticity thiab ntom ntom nti txoj kev sim yog kuaj cov nyhuv ntawm cov xim thaj thaj thiab tej zaum yuav tsis muaj kev cuam tshuam cov flaws nyob rau hauv cov ntsiab lus ntawm cov khoom, txoj kev ntsuas tus qauv zoo raws li kev ntsuam xyuas duab yog dav siv, tab sis cov ntsuas ntsuas coj feem ntau kim, luam Ntawv Kev lag luam tseem tsis tau txaus qhov tob ntawm kev tshawb fawb thiab daim ntaub ntawv.
Qhov kev luj xyuas ntawm kev luam zoo tseem yog raws li qhov kev ntsuam xyuas tus kheej raws li qhov tseem ceeb tshaj plaws, txawm tias qhov kev ntsuam xyuas tus kheej tsis tuaj yeem ua raws li kev tswj cov khoom loj.
Imatest Image Tsom xam Software
Imatest software yog digital duab zoo tsom xam software tsim los ntawm Imatest Corporation raws li MATLAB platform. Nws tau dhau los ua ib qho cuab tam rau cov duab digital zoo. Cov chaw lag luam muaj xws li cov koob yees duab, cov koob yees duab, cov khoom siv kho qhov muag, thiab luam ntawv thiab ntim.
Ntawm lawv, Imatest master software siv rau cov duab zoo li qub thiab khiav ntawm qhov rais, Mac, thiab Linux platforms.
Imatest IT (Industrial Testing) siv rau kev siv duab tsis zoo thiab kuaj hauv internet ntawm cov kab ntau lawm. Nws hu cov duab ua haujlwm thiab cov kev txhawb zog C / C ++, Python, NET c # thiab lwm yam kev tshaj xov xwm programming.
Kev lag luam luam tawm tau siv qhov cuab yeej no siv los ntawm cov tshuab ua Duab R & D rau duab thaij duab.
Imatest tswv software duab duab tsom xam txog kev lag luam luam xws li:
ColorChecker rau kev txheeb xyuas cov duab xim; Stepchart rau kev ntsuam xyuas suab (dynamic response range);
Uniformity for analysis of uniformity; Npoo ntes kom pom tseeb;
Multichart module yuav soj ntsuam cov kab kos xws li IT8.7 nquag siv rau kev tswj xim xim.
Ua ke nrog colorimeters thiab densitometers, kev tshuaj ntsuam ntawm ntau cov ntaub ntawv xim muaj peev xwm ua tau tiav.
Cov duab digital yog maj mam ua cov qauv kev yees duab rau cov duab duab hauv kev lag luam luam. Qhov zoo ntawm daim duab yog txiav txim siab tau los ntawm lub lens, lub teeb ci, kev sib tw shooting, thiab cov duab digital software. Cov kev lag luam uas twb muaj lawm hauv kev lag luam luam tsis tuaj yeem duav tau qhov kev ntsuam xyuas kev lag luam zoo ntawm cov duab digital (xws li HDR dav dluab).
Tus txheej txheem ntawm cov duab digital hauv kev lag luam luam tsis muaj kev lag luam txhim khu kev lag luam, tshwj xeeb tshaj yog rau kev luam cov artworks xws li cov duab thaij duab. Thaum peb cia siab rau cov koob yees duab los mus saib cov duab, qhov kev hu nkauj no yuav yog qhov tseem ceeb. Kev lag luam luam kuj tseem xav tau tshawb ntau txoj hau kev luam thiab ntsuam xyuas cov duab. Kev ntsuam xyuas cov duab zoo tuaj yeem tsim theem siab nrog Imatest thiab lwm yam software, ua qhov kev ntsuam xyuas zoo ntawm digital dluab raws li cov qauv thoob ntiaj teb thiab daim ntawv thov kev lag luam luam.
