This week, Canon showcased a 250-megapixel APS-H CMOS picture sensor that’s housed in a box-like physique and accessible in each RGB and monochrome configurations. It maybe serves as a great instance of Canon’s sensor know-how however don’t anticipate finding it deployed right into a shopper digicam. The sensor and field digicam it’s housed in made an look this week on the China Worldwide Public Safety Merchandise Expo. “At this yr’s CPSE, the main focus was on the 250-megapixel high-pixel CMOS picture sensor LI8020SA, which can be utilized for high-precision flat show inspection, industrial inspection, and large-scale monitoring,” Canon says. This sensor isn’t new — Canon showcased its capabilities going again at the very least three years — but it surely may be the primary time Canon featured it so prominently in a commerce present setting. The LI8020SA is a 250-megapixel APS-H format sensor that makes use of a sq. pixel association of 1.5µm x 1.5µm pixels and might assist as much as 5 frames per second taking pictures. APS-H is a quite uncommon sensor dimension in trendy shopper pictures and sits between APS-C (Canon’s measures 22.4 by 14.9 mm) and full-frame (which measures between 35.9 by 23.9 and 36 by 24mm, relying on the producer) with a measurement of 27.9mm by 18.6mm. Picture through Wikipedia Whereas smaller than full-frame sensors, Canon’s LI8020SA has 19,568 by 12,588 efficient pixels, making it extremely excessive decision.
“The Canon LI8020SA CMOS sensor minimizes noise with out sacrificing velocity by sharing floating diffusion capacitance between a number of pixels, leading to shrunken readout circuitry and bigger photodiode sizes. Progressive studying of small 1.5µm pixels happens throughout 16 digital output channels to deal with the large quantity of picture knowledge created by roughly 250 million efficient pixels,” Canon explains. “At full decision, the LI8020SA CMOS sensor achieves a quick body fee of 5 FPS. With single Area of Curiosity (ROI) windowing, sooner body charges might be achieved by lowered decision, creating flexibility in efficiency.” As a lot as this sensor could be wanted by many photographers, it’s not meant for the creation of artwork. Canon describes it as finest used for flat-panel-display inspection (4K, 8K panel), industrial inspection, video manufacturing, safety, wide-area surveillance, aerial mapping, digital archiving, and microscopes. Like a lot of Canon’s impressive-sounding industrial sensors, this one doesn’t appear sure for shopper use. Picture credit: Canon
