Canon New DSLR Rumors, Variable Low Pass Filters, and Selling Sensors to Non-Canon Customers?

by planetMitch1 Comment

While there’s been a lot of conversation about whether Canon is on the bleeding edge of camera tech or not, Canon’s quietly (or maybe not so quietly if you look at their booths at the big shows) continuing to push the envelope. Here’s a round up of some of the rumors and news from Canon lately.

The two stories below the camera rumor are most interesting to me…

While I admit I don’t totally understand the patent on the variable optical low pass filter, the concept based on the title is indeed intriguing. I’m kind of tired of people complaining about the OLPF Canon puts in the DSLRs. And maybe Canon’s got some great experience with the concept considering the Canon EOS 5Ds R has an OLPF but also includes a cancellation filter to reduce the affect of the OLPF – so it isn’t like some cameras that simply remove the filter. My point being that Canon’s very invested and has complete knowledge of the impacts of these filters and therefore probably is very knowledgeable about how to make one be variable.

It is also very interesting that Canon is branching out and offering DSLR and video sensors to other vendors. The 120mp sensor was first demonstrated back in 2010 so it has been around for a long time!

New Rebel DSLR Coming for CES in January [CR2]

Via Canon Rumors:

The next DSLR from Canon will apparently be a Rebel (or two) for CES in January of 2017. Canon generally announces consumer DSLRs and PowerShot cameras for the show in Las Vegas.

The source told us that there is some talk internally about the camera(s) coming with a new type of viewfinder for a Canon DSLR.

We don’t know if the Rebel T6 series is being replaced, or if the Rebel SL1 is going to finally see a direct replacement.

Patent: Canon Develops Variable Optical Low Pass Filter

Via Canon Rumors:

Canon has patented a variable optical low-pass filter, or (OLPF) which uses the autoexposure sensor to change the low-pass effect up or down.

Patent Publication No. 2016-173437 (Google Translated)

  • Published 2016.9.29
  • Filing date 2015.3.17
  • Performing object recognition using an image sensor AE sensor
  • Using a variable OLPF for false color reduction
  • Image quality decreases when focus deviation occurs is generated by the temperature, is detected object recognition is erroneous
  • It suppresses the effect of the variable OLPF according to the temperature, suppressing the influence of the deterioration in image quality

Canon Inc. to Sell Sensors to Third Parties

Via Canon Rumors:

As reported back in August, Canon is going to be selling sensors for OEM use. It’ll be interesting to see who is the first to use the 120mp CMOS sensor.

Keep in mind these image sensors will likely be used for something other than still cameras, and could appear in things like cars, robots and other pieces of technology.

    An optical low-pass filter in a digital camera does exactly the same thing a low-pass filter does in digital audio. It removes information above twice the sample rate that would otherwise be aliased into the image or audio.

    If you get the sensor’s resolution high enough, there’s no need for a low-pass filter, because no lens would deliver sufficiently high resolution to create aliasing.

    I don’t understand what Canon is talking about — specifically, why variability is needed. I suspect this is a relatively trivial patent whose abstruseness is intended to impress.
