Patent: Fingerprint ID on Your Cameras and Lenses
« on: January 29, 2018, 10:00:43 AM »
Here’s an interesting patent from Canon. This patent covers fingerprint ID on your cameras and lenses that can control custom functions such as IS, AF and likely anything else you can think of. It also offers the ability to customize the camera and/or lens for multiple users as well as offering a complete lockout of the gear.

Below is a flowchart showing how it works.

You can see the patent at the USPTO web site.

It better work better than iPhone finger print ID.

It’s a camera, for goodness sake – FaceID, Canon.  C’mon...innovate!

it's all about identifying who took - or might be about - to take "unwanted photographs". At least the "function" can be can shut-down with a strip of gaffer tape ... or at worst a strip of clean tape with somebody's finger print.

+1. We don't need a "function" like this. Even GPS should be removed from all cameras and phones. Canon should work hard on a sensor that is able to decrease diffraction and has better noise performance instead of stupid things like this.

No, no... super high resolution iris scan as you put your eye to the viewfinder :D

Unlock your phone!

It would be cool if it could be rolled into anti-theft.  Lens won't AF or AE if it's not unlocked; camera won't take pictures.

I’ve had the 5s and 7, while the 5s fingerprint recognition was a bit fussy (first generation) I find the 7´s to be rock solid. It’s just works-it’s reliable, and super fast.  Fast enough that if I just want to get to the camera from lock screen I need to wake it up with the power button or a different finger.  With my thumb it turns on and unlocks all in an instant.  I’ve not really had an issue to be able to say it needs improvement asides from being fussy with water like every other touch screen I’ve ever tried.

A sensor to decrease diffraction.  Please explain this to me..?

Always remember to lock your rental lenses before sending them back to Roger :o

Way to go! Give the people what they want. Who needs IBIS or Nikon level dynamic range across the entire lineup. This is much, much more useful.  ;)

I'd love to be the first person to explain to an art director that my camera is locked and I can't take photos since it's attached to my assistant's fingerprint, who isn't on set.

Yea, poor Roger & LR folks, they'd need a magic reset'er for use because you know that a firmware reset to defaults is done on every return.

That's where the innovation kicks in... After you brick your gear, you will be able to use an online "un-bricker" which will be neatly placed behind a toll booth. Cha-Ching!! Roger will of course enjoy a volume discount.

A sensor to decrease diffraction.  Please explain this to me..?
Diffraction depends on aperture and the pixel size of the sensor. The smaller the pixel size the smaller the DLA (Diffraction Limited Aperture). It is about f/9 on an APS-C camera with an 18 MP sensor and about f/14 on a FF camera with a 24 MP sensor. Probably the DLA could be increased to f/13 and f/22 if the sensor has some larger pixels at the center area and some smallers near the edge. I don't know if this can be done, just thinking about it. :)

Is it not the case that, while diffraction is more apparent at a pixel level at a given aperture with higher resolution sensors, for the same size sensor output to the same size (printed or on screen, i.e. NOT viewed at 100% magnification), it affects the image to the same degree? Which is to say, that although the DLA for the 5Ds is lower, it does not affect the image any more than it does on a 1Dx?

As for variable pixel size, wouldn't that mean subjects in the centre were less megnified than at the edges, causing weird distortion?

A solution in search of a problem...... no thanks!

Just because you can do something, does not mean that you should do it.....
