I'm betting you're scratching your head wondering about this one… but it does have significant potential for planet5D readers.
Yes, you read it right, Canon has developed an APS-H sized sensor that is approximately 250mp. Remember that APS-H is between and APS-C and Full Frame in size so this isn't a monster sensor physically tho it does have a boat load of pixels crammed on that little chip!
Let's put that in perspective, the Canon EOS 5D Mark III is 23mp, the Canon EOS 5Ds is 50mp – so this is 5x the number of pixels as the current Canon megapixel monster.
Quite a feat putting that many pixels on a small chip!
Back in 2010 at the last Canon Expo, Canon showed an APS-C 120mp sensor that wowed the crowd. At that same show, if you recall, they showed their first 4k video camera (which we all affectionately called the “hairdryer”).
Canon isn't aiming this beast 250mp sensor at you and I tho. It is more for security or military use (see the PR below)… but as with Formula 1 racing, the manufacturers are all testing bleeding edge (maybe I shouldn't use that word for F1 racing? HA) technologies that sometimes make it into consumer vehicles and sometimes don't – but they're testing all that stuff out to help future generations of tech. And that's what is going on here too.
Something like “ultra-high signal readout speed of 1.25 billion pixels per second” can certainly trickle down to consumer and pro grade cameras – we all want more data coming down the pipes for our video right?
Of course, questions come up about lenses, and bodies, and all kinds of other things, but that we'll find out down the road.
Plus, we'll get a peek at this at the Canon Expo this week!
So what do you think? Cool? Crazy? Waste of time? Sound off below!
Canon Develops APS-H-Size 250mp Sensor
Via Canon Rumors:
TOKYO, September 7, 2015—Canon Inc. announced today that it has developed an APS-H-size (approx. 29.2 x 20.2 mm) CMOS sensor incorporating approximately 250 million pixels (19,580 x 12,600 pixels), the world’s highest number of pixels (1) for a CMOS sensor smaller than the size of a 35 mm full-frame sensor.
When installed in a camera, the newly developed sensor was able to capture images enabling the distinguishing of lettering on the side of an airplane flying at a distance of approximately 18 km from the shooting location.(2)
With CMOS sensors, increases in pixel counts result in increased signal volume, which can cause such problems as signal delays and slight discrepancies in timing. The new Canon-developed CMOS sensor, however, despite its exceptionally high pixel count, achieves an ultra-high signal readout speed of 1.25 billion pixels per second, made possible through such advancements as circuit miniaturization and enhanced signal-processing technology. Accordingly, the sensor enables the capture of ultra-high-pixel-count video at a speed of five frames per second. Additionally, despite the exceptionally high pixel count, Canon applied its sensor technologies cultivated over many years to realize an architecture adapted for miniaturized pixels that delivers high-sensitivity, low-noise imaging performance.
Video footage captured by the camera outfitted with the approximately 250-megapixel CMOS sensor achieved a level of resolution that was approximately 125 times that of Full HD (1,920 x 1,080 pixels) video and approximately 30 times that of 4K (3,840 x 2,160 pixels) video. The exceptionally high definition made possible by the sensor lets users crop and magnify video images without sacrificing image resolution and clarity.
Canon is considering the application of this technology in specialized surveillance and crime prevention tools, ultra-high-resolution measuring instruments and other industrial equipment, and the field of visual expression.
