Abstract: The drone comprises a camera (14), an inertial unit (46) measuring the drone angles, and an extractor module (52) delivering image data of a mobile capture area of reduced size dynamically displaced in a direction opposite to that of the angle variations measured by the inertial unit. Compensator means (52) receive as an input the current drone attitude data and acting dynamically on the current value (54) of an imaging parameter such as auto-exposure, white balance or autofocus, calculated as a function of the image data contained in the capture area.

Abstract: The drone comprises a camera (14), an inertial unit (46) measuring the drone angles, and an extractor module (52) delivering image data of a mobile capture area of reduced size dynamically displaced in a direction opposite to that of the variations of angle measured by the inertial unit. The module analyses the image data elements of the useful area to assign to each one a weighting coefficient representative of a probability of belonging to the sky, and defines dynamically a boundary of segmentation (F) of the useful area between sky and ground as a function of these weighting coefficients. Two distinct groups of regions of interest ROIs are defined, for the sky area and for the ground area, respectively, and the dynamic exposure control means are controlled as a function of the image data of the ROIs of one of these groups, in particular by excluding the ROIs of the sky area.

Abstract: The accessory includes a coupling part configured for the removable coupling of the accessory on the reception support, a connector configured for the electrical connection of the accessory to the reception support, and at least one sensor configured to generate an output signal representative of a physical property. The connector is directly connected at the output of the sensor to transmit the output signal from the sensor to the reception support without processing of the output signal between the sensor and the reception support.
