Abstract: A color sequential display method and apparatus that reduces or eliminates color breakup. In a given frame an illumination source provides a first illumination color in a first subframe, a second illumination color in a third subframe, and both the first and second illumination colors simultaneously in a second subframe to provide a third mixed illumination color. A pixel is driven either: (a) during the first subframe to display the first color; or (b) during the third subframe to display the second color; or (c) at least during the second subframe to display the third color.

Abstract: A method and system are disclosed for enhancing the visibility of features of an image. The method comprises the steps of acquiring image data corresponding to at least one image feature using sensing means; processing the image data to identify changes in adjacent data points corresponding to a boundary of the at least one image feature; and, generating modified image data corresponding to the processed image data.

Abstract: A monitoring system is disclosed which includes at least one experiment node at which, in use of the system, a user participates in a study, and a control node. The experiment node includes communication devices operable to communicate with the user, a user input operable to record the response of a user to a prompt, a user interaction device operable such that the user can interact with the experiment node, and a device to record data relating to such user interactions. The control node is remote from the experiment node and in communication therewith to receive information including user responses and recorded user interaction data therefrom. The control node is also operable to configure the at least one experiment node to execute a plurality of human factors tests on the participant at predetermined times. The monitoring apparatus also includes a co-ordination device operable to co-ordinate the information with the predetermined times.

Abstract: In a head-mounted display system a viewed scene is optically compressed before being incident on a detector so that the peripheral regions of the image, which will appear in the viewing person's peripheral vision, are compressed more than the central region. The image is relayed to a display where an inverse optical expansion is applied, so that a wide field of view with high resolution at the centre is obtained from a relatively small display.
