<p>A portable facial image synthesiser consisting of a box 1 containing a small T.V. camera 2 directed towards a device (7) which temporarily supports alternative illustrations of eyes, noses and mouths. Controls outside the box allow a witness, or a police-operator, to alter the mutual orientation, or distance apart of the facial parts, so altering the apparent width, separation and size of the facial elements as seen on an external television screen, which may be situated in the witness's home or in a police station, until the witness is satisfied that a likeness has been achieved. Two voltage controls (6) outside the box allow the adjustment of the relative illumination of the facial features and the background so as to assist the illusion of coalescence of the separate parts of the facial image. A permanent record of the synthesised face is obtained by photographing the television screen. <IMAGE></p> |
