Taw qhia
Puas tau thaij duab nrog lub qhov rais ci hauv keeb kwm yav dhau, tsuas yog pom lub qhov rais yog dawb kiag li thiab tus neeg nyob rau pem hauv ntej tsaus dhau? Los yog sim tshuaj xyuas lub ntsej muag zoo nkauj thiab ploj tag nrho cov ntsiab lus hauv qhov tseem ceeb? Qhov ntawd yog qhov teeb meem dynamic range. High Dynamic Range (HDR) technology daws nws. HDR tso cai rau lub koob yees duab sensor los ntes cov ntsiab lus hauv ob qho tib si ci ntsa iab thiab qhov tsaus ntuj ntawm qhov xwm txheej ib txhij. Ntawm Kev Ntseeg, peb tau tsim lub koob yees duab modules rau ntau tshaj 30 xyoo, thiab HDR yog ib qho tseem ceeb ntawm peb cov kev kho mob, kev lag luam, thiab cov neeg siv khoom daws teeb meem. Kab lus no piav qhia tias HDR yog dab tsi, nws ua haujlwm li cas, thiab vim li cas nws tseem ceeb.
HDR yog dab tsi?
HDR stands rau High Dynamic Range. Dynamic ntau yog qhov piv ntawm qhov ci tshaj plaws thiab qhov tsaus ntuj tshaj plaws ntawm cov duab uas lub koob yees duab tuaj yeem ntes tau. Ib qho xwm txheej uas muaj ntau yam muaj zog muaj ob qho tib si ci ntsa iab (xws li lub hnub ci los ntawm lub qhov rais) thiab qhov tsaus ntuj heev (xws li ntxoov ntxoo hauv qab rooj). Cov koob yees duab txheem feem ntau tawm tsam nrog cov xwm txheej zoo li no, txawm tias tshuab tawm qhov tseem ceeb lossis poob duab ntxoov ntxoo nthuav dav.
HDR nthuav dav qhov muaj txiaj ntsig zoo, tso cai rau lub koob yees duab los ntes cov ntsiab lus thoob plaws ntau qhov ci ntsa iab. Qhov tshwm sim zoo li ntau yam uas tib neeg lub qhov muag pom.
Vim li cas HDR teeb meem
Kev kho mob Endoscopy
Teeb pom kev zoo sib txawv heev hauv lub cev. Ahdr endoscope koob yees duabcaptures nthuav dav nyob rau hauv ob qho tib si ci highlights (qhov twg lub teeb qhov chaw yog qhia) thiab tsaus ntxoov ntxoo (nyob rau hauv recessed cheeb tsam). Cov kws phais pom cov ntaub so ntswg hloov pauv hloov pauv uas yuav tsis tuaj yeem plam.
Kev soj ntsuam kev lag luam
Kev tshuaj xyuas cov hlau ci ci, vuam seams, lossis cov khoom cuam tshuam ua rau muaj qhov tseem ceeb heev. HDR captures cov ntsiab lus nyob rau hauv ob qho tib si reflective highlights thiab tsaus crevices.
Kev soj ntsuam kev ruaj ntseg
Sab nraum zoov scenes muaj lub hnub ci ci thiab cov duab ntxoov ntxoo sib sib zog nqus. HDR ua kom lub ntsej muag thiab daim ntawv tso cai pom tau txawm tias muaj teeb pom kev nyuaj.
Automotive
ADAS cov koob yees duab yuav tsum tswj qhov kev tawm ntawm qhov chaw, cov teeb taws yuav los, thiab duab ntxoov ntxoo. HDR yog qhov tseem ceeb rau kev txheeb xyuas cov khoom ntseeg tau.
Consumer USB Cameras
Rau webcams thiab video conferencing, HDR txhim kho cov duab zoo hauv backlit lossis teeb pom kev zoo sib xyaw. Akoob yees duab usb modulenrog HDR tsim cov yeeb yaj kiab zoo tshaj - saib.
HDR ua haujlwm li cas
1. Ntau Qhov Kev Tshaj Tawm (Sequential)
Lub sensor ntes ntau cov duab ntawm qhov sib txawv ntawm qhov sib txawv -underexposed (highlight nthuav dav), raug raug, thiab overexposed (duab ntxoov ntxoo nthuav dav). Cov no tau ua ke los tsim ib daim duab HDR. Ua haujlwm zoo rau cov scenes tseem; kev txav tuaj yeem ua rau cov khoom cuav.
2. Staggered HDR (Kab-Raws li)
Cov kab sib txawv ntawm lub sensor raug nthuav tawm ntawm ntau theem. Txo cov duab kos duab tab sis yuav tsum tau tsim tshwj xeeb sensor.
3. Sensor-Qib HDR (Dual Gain)
Advancedcmos module koob yees duabsensors muaj ob qhov nce hauv ib pixel-ib qho rau qhov tseem ceeb, ib qho rau duab ntxoov ntxoo- ntes ib txhij. Muaj tseeb ib zaug - raug HDR nrog cov khoom siv tsawg tsawg.
4. Digital Overlap HDR (DOL-HDR)
Feem ntau hauv tsheb thiab kev ruaj ntseg, DOL-HDR ntes tau ntau qhov kev nthuav tawm sai sai thiab sib xyaw ua ke. Ua haujlwm zoo thiab ua haujlwm zoo nrog kev txav chaw.
Ntsiab Specifications
Dynamic Range (dB)
Standard sensors: 60dB-70dB. HDR sensors: 100dB–120dB+. Tib neeg lub qhov muag pom txog 120dB hauv ib qho xwm txheej.
Kev daws teeb meem
HDR muaj nyob rau hauv cov kev daws teeb meem. A4k koob yees duab modulenrog HDR muab ultra-siab-txhais yees duab nrog cov dynamic ntau yam.
Form Factor
HDR muaj nyob rau hauv ntau qhov ntau thiab tsawg. Ame koob yees duab modulenrog HDR haum rau hauv cov khoom siv compact xws li endoscopes, drones, lossis wearables.
