Abstract
A digital camera system has integrated accelerometers for determining static and dynamic accelerations of the digital camera system. Data relating to static and dynamic accelerations are stored with recorded image data for further processing, such as for correcting image data for roll, pitch and vibrations and for displaying recorded images with a predetermined orientation using information about, e.g., roll. Data may also be used on-the-fly for smear suppression caused by vibrations.
