  • From wearable cameras to addressing developing nations

    A wearable camera is one idea to come out of the "casual capture" programme at HP's Bristol labs, which silicon.com visited this week.

    There are currently no product plans for the device but the latest prototype being demonstrated here consists of a camera integrated into the centre of the glasses which can simultaneously capture 1.3 megapixel stills at 7.5 frames per second and 0.3 megapixel video footage at 30 frames per second.

    The data is stored on a processing unit worn around the waist that can store three hours of footage on its two 20GB disk drives.

    The camera is continuously recording footage but the user presses a button on the processing unit when something of interest happens that they want to capture. At this point the machine saves the previous 20 seconds and the next five minutes of camera footage.

  • The quality of the images is surprisingly good - as seen here from footage taken using the prototype wearable camera by HP's Phil Cheatle on a family holiday climbing in the Italian Dolomites.

    Cheatle said: "We wanted something that's ridiculously easy to use."

    Of course there is too much raw footage for the user to process and select manually so HP developed image filtering and automatic analysis technology to do the hard work for them.

    The saved footage is downloaded to a PC where sophisticated head motion detection algorithms determine which bits are most likely to be of interest to the user and whether a still, panorama or video clip is the most appropriate format.

    The user can then review the edited footage and raise the "interest threshold" rating so that only highlights are selected or lower the threshold so that more footage is shown.
