a display system for a cockpit of an aircraft configured to allow information to be displayed on a display unit in such a way that this information is visible to a pilot of the aircraft overlayed with an outside environment of the aircraft; and
an image acquisition system, comprising at least one image sensor and provided to acquire images of the outside environment of the aircraft,
wherein the display system is configured to receive images produced by the image acquisition system and to display these images on the display unit,
wherein the image acquisition system is configured to associate ancillary information with at least a part of the images produced, and
wherein the display system is configured to:
check an integrity of an image received from the image acquisition system, based on ancillary information associated with that image; and
in an absence of the integrity, deactivate the display on the display unit of at least said image received from the image acquisition system,

wherein the ancillary information corresponds to a predefined pattern and the display system is configured to:
when the display system receives an image from the image acquisition system, search for the predefined pattern in the received image and determine a position of the predefined pattern in the received image;
determine a deviation between the position of the predefined pattern in the received image and a reference position;
determine either an integrity of the received image if this deviation is less than a predetermined value, or an absence of integrity of the received image if this deviation is greater than or equal to said predetermined value.
