Claim One:
1. A method for detecting the ingestion of an object by an aircraft turbine engine during a mission, the method including the steps of: (a) acquiring during the mission of the aircraft, digital images of the operating fan of the turbine engine, these images being acquired at an acquisition frequency proportional to the speed of rotation of the fan and to the number of blades of the fan (E 10 ); (b) identifying the different phases of the mission of the aircraft (E 40 ); (c) for each phase of the mission, comparing the images of the operating fan acquired for this phase of the mission with at least one reference image corresponding to sound operation of the fan for this phase of the mission (E 60 ); (d) if necessary, identifying each abnormal image of the operating fan which differs from the corresponding reference image, the identification of an abnormal image of the operating fan corresponding to the crossing of an alert level for detecting the ingestion of an object by the turbine engine (E 90 ).
