A IMX291 Se so solves the u de lyi g p oblem on the pixel stage, so the got here a module ca ely o whateve ambie t mild is al eady p ese t athe tha addi g a light-weight sou ce that d aws atte tio to itself.
The Bolt-291CRS is constructed a ou d the So y STARVIS IMX291 Got here a se so , a 1/2.8 i ch Again-Aspect Illumi ated CMOS system with a 2.9-mic o pixel pitch that delive s 2MP esolutio i 1920 by 1080 pixels. Positio i g the wi i g laye behi d the photodiode laye athe tha i f o t of it lets mo e i comi g photograph s every every pixel, which is the co e e gi ee i g easo a So y STARVIS Got here a captu es a clea picture at mild ranges that ove whelm a f o t-illumi ated se so of simila esolutio .
This pixel a chitectu e pai s with a IMX291 Low Gentle Se so g ade sig al chai that retains ead oise low eve as gai i c eases to compe sate fo da ok ess. The esult is a Low Gentle MIPI Got here a that p oduces a steady picture athe tha a g ai y o e whe the se so is pushed to its se sitivity limits.
Rathe tha outi g picture information th ough a USB co t olle , the Bolt-291CRS exposes its output di ectly ove a 2-la e MIPI CSI-2 i te face to the host p ocesso . This emoves a e ti e stage of se ializatio a d powe co ve sio f om the captu e path, which lowe s system powe d aw a d educes late cy betwee se so eadout a d the f ame eachi g the picture p ocessi g pipeli e. A MIPI CSI-2 Low Gentle Got here a a chitectu e like this fits embedded su veilla ce platfo ms whe e eve y compo e t i the powe funds matte s.
The IMX291 makes use of a olli g shutte eadout properly suited to the la gely static f ami g typical of a hard and fast su veilla ce got here a o a pe imete mo ito i g statio . The module is ated ac oss a ope ati g a ge of egative 30 deg ees Celsius to 70 deg ees Celsius, so the identical desig ca be deployed i a outdoo e closu e th ough seaso al tempe atu e swi gs with no sepa ate the mal qualificatio cycle.
The Bolt-291CRS is Vadzo Imagi g’s ewest additio to its Bolt MIPI got here a se ies a d its fi st e t y constructed particularly a ou d So y STARVIS fo low mild pe fo ma ce. As a IMX291 MIPI Got here a, the module pai s the se so with a facto y-calib ated S-Mou t le s i a compact fo m facto desig ed fo di ect i teg atio i to embedded su veilla ce a d visio techniques.
System i teg ato s buildi g a Embedded Visio Low Gentle Got here a deployme t eed a se so that pe fo ms on the edges of accessible mild with out addi g system complexity. Co figu ed as a Low Gentle Embedded Visio Got here a, the Bolt-291CRS delive s that pe fo ma ce di ectly ove MIPI CSI-2 so e gi ee i g groups ca focus o the su veilla ce applicatio athe tha compe sati g fo a se so that st uggles afte da ok.
Co ve tio al f o t illumi ated se so s lose a mea i gful sha e of i comi g mild to the wi i g laye sitti g o prime of the photodiode. A STARVIS Low Gentle Got here a avoids that loss e ti ely by placi g the photodiode above the wi i g laye , so ea ly eve y accessible photograph eaches the light-se sitive a ea. The Bolt-291CRS makes use of this back-side illumi ated a chitectu e to fu ctio as a Ult a Low Gentle Got here a able to p oduci g colo element at mild ranges near moo mild with no y added illumi atio .
Addi g i f a ed illumi ato s to every usable se sitivity is a commo wo ka ou d, however it i c eases price, wi i g complexity, a d powe to d aw. A Excessive Se sitivity Low Gentle Got here a solves this atively on the se so stage. The Bolt-291CRS fu ctio s as a Evening Visio Se so Got here a that elies o ative pixel se sitivity athe tha a exte al mild sou ce, which retains the overall i stallatio easy a d much less expe sive to deploy at scale.
Resolutio a d low mild se sitivity wo ok agai st every othe o a hard and fast se so dimension as a result of smalle pixels a e eeded fo highe esolutio to gather much less mild. Vadzo Imagi g tu es this t ade-off delibe ately, choosi g a Low Gentle CMOS Got here a pixel geomet y that favo s se sitivity ove pixel cou t. The esult is a 2MP MIPI Got here a that stays clea a d usable lo g afte a highe esolutio se so is ove whelmed by oise.
