How is digital handycam kept so steady?

    I have a Sony digital Handycam DCR-TRV33.
    Great little camera even though I haven't figured out all the features yet.

    On thing that amazes me is how steady it is.

    I attach it to my powered parachute and have got some good viedo.

    I wonder how the picture is kept steady and vibration free.

    The camera is attached to the machine's frame so it does all the rocking and rolling that the machine does.

    But when the tape is viewed the machine's front end is seen moving around within the picture and the camera view is mostly steady like it's sitting on gyros.

    What a cool feature.:cool:

    How do they do that?

    I hate to say this but
    Read your manual. It explains it very clearly.

    ;f That must be one of the parts I haven't gotten to yet.
    Thanks.

    Nope, doesn't give a clue how they do it.
    Just that "Steady Shot" compensates for camera shake and how to turn it off and on.


    Just think if this technology could be applied to your hand while shooting a pistol.;f

    Basically there are two ways of doing this. First, there is the optical method. It consists of a gyro to detect camera movement and a floating lens or prisms that correct for that movement, thus stabilizing the picture that is recorded onto film. Second is the electronic method. This works by capturing a larger picture on the CCD than is actually recorded and electronically shifting the recorded portion based on slight camera movement, reducing or eliminating the perceived motion.

    The optical method is generally considered superior since the electronic method sacrifices resolution (pixels) to accomplish the image stabilization while the optical method has the same resolution whether the image stablization is on or off.

    Apparently your camcorder uses the electronic method.

    Thanks podwich,

    Interesting.
    I'm sure the electronic method is used.
    I can't imagine little gyros in this little camera.

    Camera Manual quote, "Attachment of a conversion lens may influence Steady Shot"
    It sounds like what you said, "This works by capturing a larger picture on the CCD".


    I'll have to put this camera in an RC airplane and see how it does.:)
