Canon goes big on resolution with 250-megapixel sensor

Images from the APS-H format CMOS sensor can distinguish lettering on a plane flying 18 kilometers away

If you haven't had enough of camera resolution wars, Canon has developed an image sensor with a resolution of 250 megapixels.

The 19,580 by 12,600 pixels in the APS-H format sensor, measuring about 29.2 millimeters by 20.2mm, constitute the highest pixel count for a CMOS sensor smaller than full-frame 35mm size, the company said.

The resolution is 125 times full HD video, about 30 times 4K video and some 7.5 times 8K, a format with 7,680 by 4,320 pixels that will be used in regular broadcasts in Japan in 2018.

Improvements in signal processing and circuit miniaturization give the sensor a signal readout speed of 1.25 billion pixels per second. The sensor can also capture high pixel-count video at five frames per second.

The sensor was mounted into a prototype camera and was able to capture images in which the lettering on a plane flying some 18 kilometers away can be made out. The stunt involved optical and digital zooming, as well as magnification of a very small area of the photo.

Canon's new sensor was mounted in a prototype camera, seen here with a EF35mm f/1.4 USM lens.

The new sensor follows Canon's development of a 120-megapixel CMOS sensor in the APS-H format in 2010.

"We realized there was a certain amount of demand in the video production and instrumentation fields for even higher pixel counts, which provided us with the impetus to start developing a 250-megapixel sensor," a Canon spokesman said via email.

The company doesn't see any potential for consumer applications of the technology because it would require exceedingly high optical performance to take advantage of the resolution's potential.

Canon envisions potential business uses for the sensor in surveillance, crime prevention and high-resolution measurements.

Security cameras have become a focus for Canon amid wilting demand for compact digital cameras, once a mainstay product.

Earlier this year, it acquired Swedish security camera maker Axis communications and recently announced it will launch a security camera next year with an ultra-telephoto zoom lens and an F-value of 2.4 that can grab color imagery in near-darkness.

Educating from the epicentre - Why distributors are the pulse checkers of the channel

Educating from the epicentre - Why distributors are the pulse checkers of the channel

​As the channel changes and industry voices deepen, the need for clarity and insight heightens. Market misconceptions talk of an “under pressure” distribution space, with competitors in that fateful “race for relevance” across New Zealand. Amidst the cliched assumptions however, distribution is once again showing its strength, as a force to be listened to, rather than questioned. Traditionally, the role was born out of a need for vendors and resellers to find one another, acting as a bridge between the testing lab and the marketplace. Yet despite new technologies and business approaches shaking the channel to its very core, distributors remain tied to the epicentre - providing the voice of reason amidst a seismic industry shift. In looking across both sides of the vendor and partner fences, the middle concept of the three-tier chain remains centrally placed to understand the metrics of two differing worlds, as the continual pulse checkers of the local channel. This exclusive Reseller News Roundtable, in association with Dicker Data and rhipe, examined the pivotal role of distribution in understanding the health of the channel, educating from the epicentre as the market transforms at a rapid rate.
