Automated camera apparatus comprises a head mounted electronic camera 1 for providing a video signal 3 representative of an image 2 viewed by the wearer, video signal processor 51 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 12, the means 51 including image analyser 5 for identifying the presence of features and their locations relative to a reference position (e.g. the center) in the frame within each of a series of frames in a time window of the video signal, and track analysis means 7 coupled to the output of said image analyser for analysing the movement of at least one said feature over said series of frames to provide the saliency signal. As shown saliency signals 8 are provided for each or selected features identified in the scene and are thresholded in circuit 9 to provide binary signals 10, ORed together at 11 to provide a two-level or binary saliency signal 12 which is positive for salient features and zero otherwise. The video signal is delayed 4, and the end (only) of a positive saliency signal 12 is delayed 13 prior to recording 15 of both signals. The signal 12 may be derived in real time or from a video recording. Account may be taken of head and/or eye movement.
