Abstract:     A camera display system displays information via a matrix display element mounted within a housing that is positioned relative to at least eye of a user. The display is connected to a video or image sensor such that the user can view information or images shown on the display. The display can be mounted to a housing so that the user can move the display in and out of the user's field of view.
