Abstract
The drone comprises a camera, an inertial unit measuring the drone angles, and an extractor module delivering data of an image area (ZI) of reduced size defined inside a capture area (ZC) of the sensor. A feedback-control module dynamically modifies the position and the orientation of the image area inside the capture area, in a direction opposite to that of the angle variations measured by the inertial unit. The sensor may operate according to a plurality of different configurations able to be dynamically selected, with a base configuration using a base capture area (ZCB) for low values of roll angle (θ), and at least one degraded mode configuration using an extended capture area (ZCE) of greater size than the base capture area (ZCB), for high values of roll angle (θ).
