Abstract:
1. A display system comprising an electronic calculator and an associated semi-transparent display device, said display device intended to be arranged in front of an outside landscape, wherein the display device consists of two overlaid semi-transparent flat display screens and a photo-sensitive sensor intended to be arranged in front of the same outside landscape, a first display screen being passive, its transmission rate being controlled by the electronic calculator as a function of the outside landscape luminance information output by the photo-sensitive sensor, a second display screen being active, its light emission being controlled by the electronic calculator, an image generated by the electronic calculator being displayed on one of the two displays, either on the first display screen or on the second display screen as a function of the outside landscape luminance information output by the photo-sensitive sensor, wherein the display system contains a position detection system intended to be carried by a user head, comprising the electronic calculator to determine a fraction of the outside landscape seen by said user through the semi-transparent display device, the image generated by the electronic calculator being displayed either on the first display screen, or on the second display screen as a function of the luminance information of said fraction of the outside landscape output by the photo-sensitive sensor, and wherein the photo-sensitive sensor being a camera, comprising the electronic calculator arranged so that a spatial transmission rate of said first passive display screen depends on the spatial distribution of the luminance levels in the fraction of the outside landscape.
