Method and a system for processing and displaying images of the surroundings of an aircraft
First Claim
1. A method of processing an image sensed by an image sensor on board an aircraft fitted with an obstacle-locator system, the method comprising:
- determining in the sensed image as a function of obstacle location data delivered by the obstacle-locator system, wherein the zone corresponds to an obstacle indicated by the obstacle location data;
generating at least one parameter as a function of brightness of the zone; and
using said modification parameter to modify the brightness of the zone to increase contrast of the zone and thereby generate a modified image in which visibility of the zone is accentuated for presentation to crew of the aircraft.

Abstract
The invention relates to a method of processing an image sensed by an image sensor on board an aircraft fitted with an obstacle-locator system, in which the position and the extent of a zone in the sensed image, referred to as the zone of interest, is determined as a function of obstacle location data delivered by the obstacle-locator system, after which at least one parameter for modifying the brightness of points/pixels in said zone of interest is determined to enable the contrast to be increased in said zone of interest, and as a function of said modification parameter, the brightness of at least a portion of the image is modified.

17. A system for assisting the piloting of an aircraft, the system comprising:
-
an image sensor configured to generate an image of an environment of an aircraft; an obstacle-locator system configured to generate obstacle location data indicative of obstacles in the environment of the aircraft; a processor configured to receive the image and the obstacle location data and to determine a zone in the image as a function of the obstacle location data, wherein the zone corresponds to an obstacle indicated by the obstacle location data; the processor further configured to generate a parameter as a function of brightness of the zone and use the modification parameter to modify the brightness of the zone to increase the contrast of the zone and thereby generate a modified image in which visibility of the zone is accentuated for presentation to crew of the aircraft.
