Canon Super-35mm Cinema Sensor Explained
« on: January 02, 2012, 07:57:00 AM »
Canon EOS C300 Whitepapers Canon has released two whitepapers for the upcoming Canon EOS C300 video camera. The first one talks about the sensor and its design considerations.

New 35mm CMOS Image Sensor for Digital Cine Motion Imaging

Conclusion

A novel new CMOS large-format single-sensor imager has been developed. It is intended to originate very high quality HD video, and it embodies a number of important technologies that collectively should support the goal to allow image capture that comes closer to the superlative imaging qualities of 35mm motion picture film.

The second whitepaper talks mostly about the system processing of the digital signal.

Sensitometric Characteristics of the EOS C300 Digital Cinema Camera

Conclusion

An important new 35mm single image sensor has been developed. It offers video imaging attributes reflective of the most contemporary in CMOS imager technology, and has elevated HD digital motion imaging to a plane that offers a viable creative alternative to 35mm motion picture film.

A great breakdown can be read at Image Sensor World.

So, no one is bothered with Canon movie equipment? :)

Are you just trolling, or do you have something about the design of the C300 sensor to contribute?

So it looks to be similair in surface area to a and aps-c sensor, but with a wide screen 1920 x 1080 style format.
The “rolling shutter” effect is reduced with higher sampling rates of 1/60th sec for 1/24 &30 frame rates.

To me it does not look to be much different from current d-SLR technology and i'm not in awe of it, but i'm not a video person.

Could someone explain why they didn't go for a larger sensor that maintains the 1.78 aspect ratio, but would still be compatible with their lenses? For example why not a 35X20mm sensor?

It seems like the industry has settled on this size (super-35) why?

Well because there is so much legacy support for that size.

The sensor technology is pretty amazing.  The way it is read and how the color values are deemed is different from DSLRs... mainly there is no debarring happening.  Combined with larger photo sites, should make for pretty amazing imagery.

I'm hoping to get a loaner from my Canon contact in the next couple weeks to see if it really is awesome :)
