What is evidenced by this situation is that whilst many componentscan be miniaturised, it may not be possible to continue this trendwith power supplies. The fact is you still need to store batterycharge somewhere, and if you reduce the size of a battery youreduce its capacity to some degree. So, if it isn t possible to keep shrinking batteries, what elsecan be done? One answer to this conundrum is provided in GB patent no. 2452352,granted on 11 April 2012 to Samsung Electronics Co. Ltd andentitled, Motion triggered power saving mode for a cameradisplay . This patent addresses the power issue by identifyingthose components which have the largest drain on the battery andattempting to make them more efficient. The invention achieves this aim by turning off the display screenwhen it is not needed. Whilst 'standby after a period ofinactivity' is a widespread feature of many electronic devices,Samsung s invention goes a step further by making a more informeddecision about turning off the power-draining display screen of thecamera. The decision to cut power to the display is based on feedback froma motion sensor incorporated in the camera. For example, after a session of photos have been taken, the photographer may maketheir way to a new location and continue to shoot photos there. Byincorporating a movement sensor in the camera, the camera scontroller can determine if it is being moved (and not used) aftera photograph has been taken and, if so, the display screen is putin power-saving mode. If the display screen is an LCD, then the backlight may be turnedoff whilst the image may is maintained in the liquid crystals, orthat may also be turned off. Alternatively, the motion sensing maybe undertaken by analysing an image received on the image detectorto see if it is changing. A simple and neat idea indeed, but have any readers come acrossthis feature in their cameras? Michael Jaeger is a patent attorney at leading UK patent and trademark attorneys, Withers & Rogers LLP.
