Canon’s Quad Pixel Might Be the Subsequent Huge Factor


One of many hallmarks of Canon cameras is Twin Pixel AF. First launched on DSLRs at a time when Stay View was usually faltering autofocus, the know-how turns every pixel into two focusing sensors. However, can Canon make the autofocus system that ranks among the many finest, if not the very best, even higher? A know-how referred to as Quad Pixel Autofocus might be Canon’s subsequent large transfer. Current patents have fueled rumors in regards to the know-how. However, simply this week Canon shared that it was the one firm to rank among the many prime 5 for the variety of U.S. patents filed for 36 years in a row. With 3,022 patents filed within the U.S. final 12 months, there are sure to be some concepts that by no means lead anyplace. Will Quad Pixel AF be certainly one of them?

Canon Rumors just lately noticed a patent spelling out further particulars on Quad Pixel Autofocus. As an alternative of dividing every pixel into two separate websites to measure focus, the know-how divides it into 4. The patent documentation says that, in part detection autofocus, the system carried out finest when the refined variations measured are getting in the identical path that the pixel is split in. By having extra divisions of that pixel, the know-how may probably enhance autofocus velocity and accuracy, the patent suggests.

Canon has revealed patents on Quad Pixel autofocus earlier than, fueling rumors that such a system may launch on an R1 physique. In fact, rumors are simply rumors — and Canon Rumors was initially calling for Quad Pixel to reach in 2021. The newest patent introduces further know-how to resolve one of many points Quad Pixel creates: the sunshine gathered by every pixel varies. Having pixels that don’t uniformly collect mild can be dangerous for suppressing noise and will gasoline different points. The brand new patent works to resolve that irregular sensitivity by “rising the division path.”

The patent additionally discusses utilizing an RGBW coloration array over the sensor, modifying the normal RGB sample that permits a digicam sensor to see coloration by including a white sq. within the combine. This design, the patent language suggests, would assist the Quad Pixel system improve accuracy when working in restricted lighting.

Understanding the patent language, which is translated from Japanese, is troublesome. When requested in regards to the know-how, Canon declined to debate future merchandise. It’s unclear when or even when a Quad Pixel AF system would make its strategy to an precise digicam physique. Equally, there might be errors in understanding the translated paperwork. Photographers gained’t get a full take a look at how the know-how works till Canon makes an official product announcement.

Canon usually sits on the prime of the checklist of corporations that publish essentially the most patents per 12 months. Simply this week, Canon mentioned it was third in essentially the most revealed patents within the U.S., with greater than 3,000 patents filed in 2021. Actually, Canon has revealed concepts which have by no means made it past paper. So, the newest patent could not ever make it right into a digicam. However, with a number of patents already revealed on Quad Pixel AF, it reveals the place their innovation is concentrated.

I’ve lengthy been impressed by Canon’s Twin Pixel Autofocus. I used to be blown away once I used autofocus on a jar of fireflies at nightfall with the EOS R6, and impressed once more when the R3 may discover and concentrate on a chook in flight at a second’s discover. Whereas spectacular, it’s good to see Canon isn’t resting smugly with the success of their newest mirrorless cameras. It’s all the time good to see corporations that make the merchandise that permit photographers to be artistic be artistic themselves. Whether or not or not the rumors fueled by the newest patents are appropriate, the patents are an indication that Canon hasn’t stagnated.
