*UPDATE* Canon Patents

Aren’t patents fun? One thing I hate about patents is I can’t read them. I read through the 4 of these and still had no idea what they were.

One of our commenters did however.

“The first patent is describing a read out shift which only is useful in video recording. The patents 2 and 3 rely on the optical IS element doing the dirty work and the third describes a way of moving the relevant lens elements in an IS lens. So nothing, as in not a single thing, is implicating more than the presence of sensors that detect motion inside the body – the chore of correcting for that motion falls to the IS group.”

So there you have it. Thanks Karl. I love when these things are explained in english.

Canon is apparently top 5 every year for patents awarded. They were #2 in 2005 behind Big Blue.

In Body & In Lens Stabilization Patents
I haven’t had any time to read through these patents thoroughly, I only have my phone. However, I’m told the following 4 patents may be of great interest to Canon users.

  1. People has measued that Canon camera’s noise is mostly generated during the Read phrase, so the first patent might be able to greatly improve image quality.

    The 3 patent is almost the same as 2nd one might be more detailed.

    The 4th patent is the machinery of patent No.2 and 3, which looking like a powershot or camcorder lense to me.

  2. One thing’s for sure: given the exploded diagram and nature of lens groupings as visible in very detailed patent drawings on the 20090232483.PDF – this is certainly no SLR lens.

    Given the nature of others’ comments regarding video feed, it could be a highly-integrated video component of a point-and-shoot variety, or a new video camera about to be released.

    Anyway, it’s non-SLR, so I’m not that piqued.
