What just happened? Canon has announced a 410-megapixel CMOS image sensor, setting a new record for the most number of pixels on a 35mm full-frame sensor. Before getting too excited, you should know that the sensor is destined for applications like surveillance, industrial imaging, and medicine that demand extreme resolution rather can consumer-grade cameras. The 410-megapixel (24,592 x 16,704 pixels) sensor boasts a resolution that is 198 times greater than Full HD, and 12 times higher than 8K. With it, users should be able to crop any part of an image without a significant drop in quality.Canon said the new sensor utilizes a back-illuminated stacked formation in which the signal processing element and pixel segment are interlayered. The imaging specialist also had to redesign the circuitry pattern, which enabled a super fast readout speed of 3,280 megapixels per second.Super-high pixel count sensors already exist in medium- or larger formats, but fitting this level of resolution into a 35mm sensor is unprecedented and will help contribute to the miniaturization of shooting equipment, Canon said.Full-color and monochrome versions of the sensor will be available. The latter will additionally feature a four-pixel binning function that effectively treats four pixels as one a trick we've seen smartphone image sensors use to boost performance, especially in low light situations. Canon said that when this feature is in use, the sensor can capture 100-megapixel video at 24 frames per second. Otherwise, video is limited to eight frames per second.Canon has been pushing the bounds of what's possible with imaging tech for a while now. Late last year, the company showed off a 250-megapixel APS-H CMOS sensor intended for industrial inspection applications. On the consumer side, we got a new EOS R series camera aimed at entry-level photographers wanting to step up from a smartphone. // Related StoriesCanon will showcase its new sensor at the SPIE Photonics West conference for optics and photonics. The show starts on January 28 and runs through the 30th in San Francisco.
