Canon gets into the consumer VR game


Canon might not be a contender in the field of consumer VR right now, but a prototype seen on the show floor at this week's Canon Expodefinitely promises good things in that arena. The development unit sports two 5.5-inch LCD panels, each coming in at 2,560 x 1,440 for a total 5K resolution -- topping many devices already on the market (or coming soon).

The VR unit isn't ready for primetime just yet, though. The current model lacks any kind of built-in audio, requiring users put on a pair of external headphones to get the full experience. And it's not a headset so much as it is a handset -- grips on each side allow users to hold it in front of their face. The plus side to this arrangement is that the eyepiece is way more comfortable for glasses-wearers.
The demo video placed me in a large golden room with a domed ceiling, placed in the center of a flamenco performance. The VR unit sports a 120 degree view, and to that effect I was able to turn my head all around to look at each performer individually, including one particularly intense guitar player situated directly behind me. The image was incredibly bright and sharp, as befitting its high resolution, but there was a disconcerting bit of blur whenever I redirected the handset to look at something new -- not as bad as say, earlier versions of the Oculus Rift, but still a noticeable flaw in an otherwise attractive experience.
Like many products at Canon Expo, the VR unit is still a work-in-progress with no set release plans. But given the amount of design polish and ergonomic consideration present in the demo unit, I wouldn't be surprised if the company has something to offer consumers soon.

Canon's 250-megapixel sensor can read the side of a plane 18km away

And you thought 12 megapixels on a camera was pretty good? Canon has developed a 250 megapixel sensor that could fit inside a DSLR.
The APS-H-size (29.2 x 20.2 mm) CMOS sensor incorporates approximately 250 million pixels(19,580 x 12,600) - the largest number of pixels crammed into a CMOS sensor smaller than a 35mm full-frame sensor, according to Canon.
The sensor is able to capture images so detailed that it would allow you to see the lettering on the side of an airplane flying 18km from the camera, Canon said.
With such sensors, increases in pixel counts result in a larger signal volume, which can cause problems such as signal delays and slight discrepancies in timing, but Canon said its CMOS sensor manages a signal readout speed of 1.25 billion pixels per second. This means it can capture "ultra-high-pixel-count" video at a speed of five frames per second.
A camera outfitted with the sensor can shoot video at around 125 times the resolution of full HD (1920 x 1080 pixels) video and about 30 times that of 4K (3840 x 2160 pixels) video.
It's a good example of the state of the art, but don't expect to see this sensor appearing in your DSLR (or your smartphone) anytime soon: Canon said the sensor could be used in specialized surveillance and crime prevention tools or ultra-high-resolution measuring instruments and other industrial equipment.
