Claim:
Automated camera apparatus comprising: an electronic camera, the camera comprising a photoelectric sensor optically coupled to imaging optics for providing a video signal representative of sequential frames of an image viewed by the camera, and at least the imaging optics being adapted for securing on the head of a wearer with its axis generally parallel to the normal forward line of sight of the wearer; a video signal processor arranged to receive said video signal for judging the degree of interest shown by the wearer in a feature in the scene and for providing a related saliency signal, the video signal processor including: a video signal analyser for identifying a presence of features and their respective locations in a frame within each of a plurality of frames in a time window of the video signal, and a movement analyser coupled to the output of said video signal analyser for analysing relative movement of at least one said feature over said plurality of frames to provide said saliency signal; and a video signal delay for delaying the video signal relative to the saliency signal.
