Patent ID: 8619030

Claim:
A method of controlling a display of a portable electronic device comprising a processor, a first motion sensor, a second motion sensor and the display, the method comprising: controlling the display to generate a representation; receiving at the processor, from the first motion sensor, first motion data representing movement of an external object relative to the portable electronic device; in response to movement of the portable electronic device including a jitter component, receiving at the processor, from the second motion sensor, second motion data representing the movement of the portable electronic device independent of the external object; generating, at the processor, third motion data by removing the jitter component from the second motion data to produce jitter-free second motion data, and determining a difference between the first motion data and the jitter-free second motion data, the third motion data representing movement of the external object independent of movement of the portable electronic device; and, controlling the display to update the representation based on the third motion data, such that the updated representation generated by the display reflects the movement of the external object independent of the portable electronic device.
