1. A method of displaying an image recorded by a digital camera system, said method comprising:

  • providing information identifying a roll angle of the recorded image, said information being provided by first and second accelerometers sensitive to accelerations in respective first and second directions to identify angles of roll, the second direction being different from the first direction;

    providing information identifying a pitch angle of the recorded image, said information being provided by a third accelerometer and the first and/or second accelerometers, the third accelerometer being sensitive to accelerations in a third direction normal to the first and second directions;

    using the provided roll angle information to determine an orientation by which the recorded image is to be displayed and/or stored, the orientation comprises portrait and landscape orientations; and

    using the provided pitch angle information to prevent unintended switching between the portrait orientation and the landscape orientation.
