Abstract
An image detection system comprises a camera (2) for generating an electrical output signal representative of the detected image. The camera is carried by a headset (1, 3) for attachment to the head of a user, and comprises a transducer (6; 106) for generating an electrical output in response to light incident thereon. Magnifying means (22) are situated in the path of light to the transducer, and is arranged to magnify the detected image. The transducer and magnifying means are positioned in such a way that, in use, the portion of the path of light passing through the magnifying means extends laterally across the front of the user's head, enabling the system to be of a relatively compact construction. The camera may include focusing means which is operatively linked to the camera body in such a way that changing the attitude of the camera alters its focus, so that tilting the camera downwards causes it to focus on proximate objects, whilst focused images of distant objects can be obtained by tilting the camera upwards.
