Abstract: A method for improving image quality of images captured by a camera system having an image sensor and implementing optical image stabilisation (OIS) comprises receiving image data representing an image captured by the camera system, receiving stabilisation position data from an OIS device in the camera system, the stabilisation position data indicating a position where an optical axis of the optical path intersects with the image sensor, and includes the step of applying a lens correction function to the received image data, wherein the application of the lens correction function is adjusted based on the received stabilisation position data, and outputting the corrected image data.
