A viewing device (10) may be utilized to facilitate viewing of a scene or event. The viewing device (10) may continuously record a sequence of frames of predetermined duration. At periodic intervals, the sequence of frames overwrite previously stored sequence of frames. When the user wishes to watch a replay of a previous sequence of frames of predetermined duration, the user can continue looking through the device (10) to see a stored sequence of frames rather than a real time display of an ongoing event. |
