According toNikkei Asia , Canon is poise to shake up the digital tomography industry next year with a new sensor capable of capturing full - colour images at “ one - ten percent the brightness conventional sensors need . ” This could revolutionize self-governing drive and even security system of rules .
Photography in low - light situations , include near darkness , is n’t unimaginable , but it requires particular proficiency that each fall with their own via media . The easiest solution is to ride a tv camera to a sturdy support like a tripod and habituate a long shutter , but that ’s an impractical solution for applications where video footage needs to be captured , or when a flow of mental image needs to be analyze in veridical time . Boosting the sensitiveness of a tv camera ’s sensor is also an selection ( referred to as its ISO ) , allowing images to be captured in the dark with a fast shutter , but that technique introduce rafts of noise in the terminal results which can often obnubilate o.k. point .
The most usual solution to depleted - light picture taking is to trust on night sight technology which seize infrared light rather of the light that falls in the seeable spectrum . It results in high - direct contrast imagery where it ’s prosperous to discern objects and finer details . But there ’s no color information , and that ’s what Canon is endeavor to relieve with its new sensors .

The new sensor Canon plan to mass green goods is based on technology the companyimproved back in 2020that allows it to capture 1 - megapixel image using a Single Photon Avalanche Diode ( or SPAD for unretentive ) . Traditional sensing element make figure of speech ground on the number of photons each pixel detects over a period of time — the more lighter and photon usable , the better the results will be . But a SPAD detector uses an electronic element in every pixel that can multiply and bring forth an electrical pulse when just a unmarried photon hits it ( the effect multiplies like an avalanche , hence the name ) , give it much bang-up sensitivity in near total darkness .
It ’s an approach to sensors that ’s been around for decades , but Canon ’s latest breakthrough , harmonize toNikkei Asia , is that the company has make a SPAD sensing element with 3.2 million pixel , which would make it the world ’s densest , and it would finally be useful for acquire gamy - quality color images even in the dark . But that ’s not a SPAD sensor ’s only neat put-on . It ’s also able-bodied to determine the space to a given object based on the time it takes for light to travel to it , reflect , and then return . That data can be processed to depend distance in three dimensions and father models of what live around a gadget with the detector installed . As a result , while Canon ’s new detector will reportedly initially be used in the company ’s security system and surveillance photographic camera offering , it will also have useful coating when it come to self-directed driving and piloting organization as the need for self - drive vehicles increases in the coming years .
