Patent Images

1. A viewing device comprising, in succession and connected in series, a screen, a display unit and one or more graphic generation units connected to the display unit by means of a switch, the graphic generation units and the display unit having a means for detecting corruption or loss of the image, in that case initiating their reconfiguration, wherein the viewing device also comprises an electronic block and an associated memory, these two components recording in a loop, in nominal operation, a series of images of approximately ten images so that it comprises one valid image originating from one graphic generation unit, one valid image being an image formed before the detection of the failure by an alarm signal, and when an incident is detected and is signaled to the electronic block, the electronic block transmits to the screen, for a period of reconfiguration of the electronic unit in question, the last valid image recorded in the memory, the duration of display of the last valid image being sufficiently short for the image-freezing effect to be imperceptible.
