Canon’s Blue Spectrum Refractive Optics technology explained (video)

Interesting short clip by Canon Imaging Plaza on YouTube about how Canon’s new Blue Spectrum Refractive Optics (BR) technology works. Pretty interesting.

The Blue Spectrum Refractive Optics (BR) lens is a compound lens that uses Blue Spectrum Refractive (BR) optics. BR optics are made from an organic optical material developed by Canon, and have anomalous dispersion properties equal to or greater than fluorite. When combined with concave and convex lenses, they can correct chromatic aberration to a degree greater than previously achievable.

BR technology is featured on Canon’s new, and highly regarded, EF 35mm f/1.4L II lens. More insights and information about Canon Blue Spectrum Refractive Optics at Canon Asia.

Samsung Galaxy S7 and S7 Edge use Dual Pixel Auto-Focus technology (is this Canon’s tech?)

Samsung Galaxy S7

Samsung announced their new Samsung Galaxy S7 and S7 Edge. The interesting point: Samsung touts both smartphones to have DUal Pixel Auto-Focus (DPAF) on board. DPAF is a technology developed by Canon and introduced first on the Canon EOS 70D in 2013.

Now, while Samsung doesn’t mention Canon anywhere, there are some statements that indirectly point to Canon. Like the following sentence taken from Samsung’s Galaxy S7 product page (emphasis mine):

Dual Pixel technology, which is utilized in selective, high-end DSLR camera models, as well as those of the Galaxy S7, sends light from the lens to two image sensors separately to adjust the focus, much in the same way that the human eye does.

Did Canon license their DPAF technology to Samsung? Or did Canon build the imaging sensor found in the Galaxy S7? I couldn’t find any pertinent information on the web. However, I guess it is an almost safe bet to say that Canon is in some way involved in the imaging sensor of the Galaxy S7.

Look how Samsung presents Dual Pixel AF:

That’s pretty similar to how Canon presents DPAF.

Below are Samsung’s Galaxy S7 introduction video as well as a video about Samsung’s implementation of DPAF.

Canon’s 250MP APS-H sensor presented at ISSCC 2016

ISSCC 2016

ISSCC 2016, the International Solid‑State Circuits Conference held in San Francisco, just closed its doors. This is a specialist conference about circuits technology, something Canon with their newly developed sensors would not miss for sure. Indeed, Canon presented their 250MP APS-H sensor, a piece of technology I reported a few times in the past.

The folks at Harvest Imaging posted a summary of the presented tech. About Canon’s 250MP sensor:

Hirofumi Totsuka of Canon presented a 250 Mpixel APS-H size imager : 1.5 um pixel pitch (4 sharing) made in 0.13 um technology node.   The device is consuming 1.97 W at full resolution 5fps.  An interesting build-in feature of this sensor is the following :  ALL pixel signals are converted by column SS-ADCs with a single ramp, but in front of the ADC, each column has its own PGA that can be switched to 4x or 1x gain, depending on the signal level.  So when the pixels are sampled, a first check is done to look whether the signal is above or below a particular reference level, and then the right gain of the PGA is set to 1x or 4x.  Simple method, but I think that the issues pop up in the reconstruction of the signal at the cross-over point between the two settings of the PGA.

I wonder when we will see this sensor technology go into production.
