Cov Duab Zoo Tshawb Nrhiav thiab Kev Ntsuam Xyuas Kev Ntsuam Xyuas
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Nrog rau kev nce qib ntawm digital technology, luam tawm kev lag luam tus nrhiav tau ntawm cov duab tau ua tag digital. Kev lig kev cai raws li lub cev thiab tshuaj xyuas lub cev xws li yeeb yaj kiab thiab yeeb yaj kiab, vim tias tus nqi siab, daim ntawv thov nqaim thiab cov khoom muag tsawg, cov tub lag luam tsis muaj cov tub lag luam zoo thiab cov ntaub ntawv loj loj. Xwb, lawv pheej yig thiab pheej yig cov koob yees duab. Kev ua ke ntawm digital rov qab thiab nruab nrab-me me hom ntawv nta scanners ntau dua thiab siv tau hauv cov tswv yim siv hauv kev lag luam luam.
Hnub no lub digital koob yees duab, uas nrov nyob rau hauv txawb tes, tau pib nkag mus rau lub billion-pixel era. Cov qauv kev siv cov txuj ci tseem yuav ua rau cov ntsiab lus tseem ceeb dua ntais. Qhov zoo ntawm digital imaging txiav txim siab qhov zoo ntawm cov duab luam los ntawm lub hauv paus. . Kev paub ntawm cov duab digital thiab cov txheej txheem replication yog nyob rau hauv kev xav tau ntawm kev tsim cov qauv kawm uas ua kom zoo tshaj ntawm cov duab luam tawm cov duab tawm, kev tswj, ntsuas thiab ntsuas tau.
Duab qhov ntsuas kev lag luam
Qhov kev luj xyuas ntawm qhov zoo ntawm cov teeb meem luam tawm yog qhov tseem ceeb ntawm tus txheej txheem rau kev luam ntawv. Kev ntsuam xyuas tus qauv ntawm cov ntawv sau tau zoo yog raws li kev ntsuam xyuas tus kheej thiab txhawb ntxiv los ntawm lub hom phiaj kev ntsuam xyuas. Lub tswv yim tseem ceeb ntawm qhov kev ntsuam xyuas tus kheej yog saib xyuas nyob rau hauv qhov chaw soj ntsuam ntawm cov teeb ci; 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 kom zoo hauv kev luam ntawv 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 catheter meter. Cov xim ntawm qhov ntsuas cov ntsiab lus ntawm qhov kev txaus siab hauv qhov screen yog sampled thiab kaw tseg rau hauv ib qho kev tshawb rau cov zauv, kev nqes tes kos, thiab kos.
2. Spectrophotometry. Qhov ntsuas tus nqi ntawm qhov teeb meem tshwm sim yog nyeem los ntawm kev ntsuas kev ntsuas tsis tu ncua xws li X-Rite XRite intellitrax lossis Konica Minolta FD-9, thiab qhov ntaus nqi ntawm cov zauv. Ntawm lawv, Intellitrax muaj ib qho kev ntsuas ntau, uas tuaj yeem tsis ua kev puas tsuaj, thaum FD-9 muaj ib hom ntawv me me.
3. Kev tshawb nrhiav hauv internet (duab hom). Lub koob yees duab CCD txaws cov duab thiab tshawb xyuas cov RGB xim qhov tseem ceeb ntawm cov ntawv luam tawm xim rau kev txiav txim thiab kev ntsuam xyuas. Txoj kev no yog siv los nrhiav cov teeb meem zoo hauv kev soj ntsuam zoo hauv lub sijhawm. Vim tias qhov ntsuas qhov ntsuas thiab software yuav ua haujlwm nyob rau hauv lub xeev nruam nruj, nws yog kev ntseeg ntau tshaj qhov kev paub tseeb.
Txij li thaum lub hauv paus ntsiab lus ntawm chromaticity thiab ceev yog ntsuam xyuas cov nyhuv ntawm ib thaj xim thaj chaw, qee zaus nws tsis muaj kev cuam tshuam cov flaws hauv cov ntsiab lus ntawm qhov khoom. Yog li, kev ntsuam xyuas tus qauv zoo raws li kev ntsuam xyuas duab yog siv dav, tab sis cov khoom siv sib piv yog feem ntau kim, luam Ntawv Kev lag luam tseem tsis muaj kev tshawb fawb thiab kev siv cov ntaub ntawv txaus.
Qhov kev luj xyuas ntawm kev luam ntawv zoo tseem yog raws li qhov kev ntsuam xyuas tus kheej raws li lub siab tshaj plaws txoj cai, txawm tias qhov kev ntsuam xyuas tus kheej tsis tuaj yeem hloov tau kev tswj cov khoom loj.
Taw qhia rau Imatest Image Tsom Xam Software
Imatest software yog ib qho digital duab zoo tsom xam software tsim los ntawm American Imatest raws li MATLAB platform. Nws tau dhau los ua cov cuab yeej dav dav rau cov duab digital zoo tsom xam. Nws muaj feem xyuam rau cov koob yees duab, cov koob yees duab, kho qhov muag, luam ntawv thiab ntawv ntim.
Tus Imatest master software siv rau cov duab zoo li qub thiab khiav tawm ntawm qhov rais, Mac thiab Linux platforms.
Imatest IT (Kev Tshawb Fawb) yog siv rau cov duab thaij duab thiab kev tsim cov kab xev hauv internet kom paub hu duab duab, kev txhawb C / C ++, Python, NET c # thiab lwm yam kev sib tham nrog programming.
Kev lag luam luam tawm tau siv qhov cuab tam, dav siv los ntawm ntws cov koob yees duab ntawm cov koob yees duab, rau cov duab saib.
Cov duab tsom xam ntawm tus Imatest master software rau kev lag luam luam nrog:
ColorChecker kev txheeb xyuas cov duab xim; Stepchart rau kev ntsuam xyuas cov suab lus (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 feem ntau siv los tswj cov kev tswj xim.
Ua ke nrog ib lub tha xim thiab ib lub densitometer, cov cuab yeej sib tw ntawm ntau cov ntaub ntawv xim muaj peev xwm ua tau.
Kev kuaj pom yog maj maj los ua lub ntsiab ntawm txoj kev duab hauv qhov kev lag luam luam. Qhov zoo ntawm cov duab yog txiav txim tau los ntawm kev sib txuas ntawm lens, lub teeb qhov chaw, shooting system thiab digital duab processing software. Cov kev tswj xim xim hauv kev lag luam luam tsis tuaj yeem npog qhov kev ntsuam xyuas kev lag luam zoo ntawm cov duab digital (xws li HDR dav dluab).
Tus txheej txheem ntawm kis digital cov duab hauv kev luam kev lag luam tsis muaj kev lag luam txhim khu kev lag luam, tshwj xeeb yog rau kev luam ntawm kev tsim duab xws li cov duab thaij duab. Thaum peb cia siab rau cov koob yees duab kom tau cov duab, qhov kev poob haujlwm no yog qhov tseem ceeb. Kev lag luam luam kuj yuav tsum tau tshawb ntau txoj hau kev los luam thiab ntsuam xyuas cov duab digital. Kev ntsuam xyuas duab zoo tuaj yeem tsim kho nrog software xws li Imatest, kom qhov kev ntsuas zoo ntawm digital cov duab tau ua raws li cov qauv thoob ntiaj teb thiab daim ntawv thov kev lag luam luam.
