Yes I know that but they also have accelerometers.
The accelerometers are used for things such as setting the orientation of the image in EXIF and horizon correction (gyroscopes cannot do that, at least not without help from accelerometers).
The gyroscopes are used for the shake reductioon, but gyroscopes are only good for reduction of angular shake. For shake reduction at close distance, in particular macro you need linear accelerometers
in addition to the gyroscopes. The gyroscopes take care of the angular motion and the accelerometers would be needed to measure the sideways (translational) motion.
What I was discussing was whether the already existing
gyroscopes accelerometers in Pentax cameras could be used for the second part of shake reduction, that part which is specifically needed for close range and macro shake reduction. The normal shake reduction has no use at all for accelerometers.
