The object of the invention is a method for securing a vehicle comprising a critical system including a display, the method comprising the following steps:

Method for securing a vehicle comprising a display, electronic security device and associated computer program product

The invention relates to a method and system for validating the graphical generation of symbols to display, comprising a graphical generation of symbols to display to form a video stream comprising a plurality of rasters, comprising a pixel generation, with the attribution of at least one associated symbol attribute for each pixel contributing to one of said symbols. The method comprises, for at least one raster of said video stream: obtaining at least one reference symbol attribute associated with at least one symbol to be monitored; identifying pixels having the reference symbol attribute(s), during a scan of the pixels of said raster in a predetermined course direction, these pixels contributing to said at least one symbol to be monitored, and calculating associated characteristic information; validating the display of the symbol(s) to be monitored based on the calculated characteristic information and of source information associated with said symbols to display.

Method and system for validating the graphical generation of symbols to display

This method for generating graphic surfaces to be displayed on a screen is implemented by a graphics processor and comprises:

Method for generating graphic surfaces to be displayed on a screen, related graphics processor

Graphics processor and related method for displaying a set of pixel(s), related platform and avionics system

Techniques for generating images with information windows including variable display priorities, the technique including selecting pixels of active windows at a given area of the image and reconstituting an image on the basis of the pixels of the selected windows. The techniques ensure mixing of the pixels and transparency between windows. The techniques apply to aircraft flight displays and any other image generating devices.

Device and method for generating variable priority multiwindow images

A display device that comprises a flag memory containing state flags of pixel areas of the image is provided. The display device comprises a display screen and a graphical generation unit implementing at least three functions for displaying an image, i.e. a first data erasure function, a second function for generating an image comprised of pixels in a first memory, and a third function for displaying the image by reading the pixels in said memory and controlling the screen, in which an image is divided into a plurality of separate pixel areas and in that each area is addressed by a flag, wherein the display device further includes a memory that stores the flag states so that the graphical generation unit can execute the display function on the basis of the flag states. The generation of images having a predominantly uniform background can, in particular, be used for application in aeronautics.
