I just read that article, and there is no way at all whatsoever to post comments on that page. So, I am posting a comment here.

The article completely missed a third type of image stabilization which uses a hybrid of the digital and optical methods, as used in many entry-level Sony HD camcorders. This method uses motion sensors in the lens while recording an image onto a sensor with more pixels than the image itself contains (using the extra pixels as a stabilization buffer). The motion sensor in the lens “tells” the recorder to shift the capture to another part of the sensor as soon as it detects camera shake - much in the same manner as a mechanical (sensor-shift) image stabilization system that’s used in some cameras (the only difference being that in the electronic stabilization described above, the sensor remains stationary relative to the camera and lens). This is true digital image stabilization (or electronic image stabilization); the “digital image stabilization” described in the article is actually only simulated (manipulating the already captured image as opposed to an electronic frame shift on sensor) - much less effective than either true digital stabilization or optical stabilization, and pure marketing BS.
