Abstract

In an aspect there is provided a method for controlling an image stabilization, system of an image capturing device, wherein the IS system comprises an optical image stabilization, OIS, system compensating for vibrational movement of the image capturing device based on a motion signal output by a motion sensor of the image capturing device, and wherein the OIS system has at least a first control parameter with a value being adjustable to adapt a responsiveness of the OIS system to vibrational movement, the value being adjustable between a first value causing a lower responsiveness of the OIS system, and a second value causing a higher responsiveness of the OIS system; the method comprising, while the OIS system is in an active state and performs OIS; determining a signal-to-noise estimate for the motion signal; and determining the value of the first control parameter based on the signal-to-noise estimate, comprising setting the first control parameter to the first value responsive to determining that the signal-to-noise estimate is in a lower range, and to the second value responsive to determining that the signal-to-noise estimate is in an upper range.
