A rotary-wing drone, comprising: - a camera, including a hemispherical field lens of the fisheye type pointing in a fixed direction (Δ) with respect to the drone body, as well as a digital sensor collecting the image formed by the lens and delivering raw pixel data; - image processing means, receiving as an input the raw pixel data and delivering as an output corrected pixel data, compensated for the geometric distortions introduced by the fisheye lens; - means for delivering as an output corrected pixel data, for transmission to a video recording or display device; - an inertial unit, adapted to measure the Euler angles (φ, θ, ψ) characterizing the attitude of the drone with respect to an absolute terrestrial system; and - automatic control means, receiving as an input at least one Euler angle delivered by the inertial unit, and adapted to window the pixel data delivered as an output by the delivery means as a function of changes of attitude of the drone detected by the inertial unit, characterized in that: - the digital sensor is a scanning sensor delivering said raw pixel data line by line; - the drone further includes means for extracting a fraction of the pixels from the image formed on the sensor, these extractor means: • receiving as an input a selection signal defining over the sensor extent the position of a capture area of reduced size, and • transferring to said image processing means, for compensation for the geometric distortions, only said raw pixel data corresponding to the capture area of reduced size; - the automatic control means are means adapted to modify dynamically said selection signal, defining the extent of said capture area of the extractor means, in a direction opposite to that of a change of attitude of the drone detected by the inertial unit and characterized by a corresponding variation of said at least one Euler angle. - a camera, including a hemispherical field lens of the fisheye type pointing in a fixed direction (Δ) with respect to the drone body, as well as a digital sensor collecting the image formed by the lens and delivering raw pixel data; - image processing means, receiving as an input the raw pixel data and delivering as an output corrected pixel data, compensated for the geometric distortions introduced by the fisheye lens; - means for delivering as an output corrected pixel data, for transmission to a video recording or display device; - an inertial unit, adapted to measure the Euler angles (φ, θ, ψ) characterizing the attitude of the drone with respect to an absolute terrestrial system; and - automatic control means, receiving as an input at least one Euler angle delivered by the inertial unit, and adapted to window the pixel data delivered as an output by the delivery means as a function of changes of attitude of the drone detected by the inertial unit, characterized in that: - the digital sensor is a scanning sensor delivering said raw pixel data line by line; - the drone further includes means for extracting a fraction of the pixels from the image formed on the sensor, these extractor means: • receiving as an input a selection signal defining over the sensor extent the position of a capture area of reduced size, and • transferring to said image processing means, for compensation for the geometric distortions, only said raw pixel data corresponding to the capture area of reduced size; - the automatic control means are means adapted to modify dynamically said selection signal, defining the extent of said capture area of the extractor means, in a direction opposite to that of a change of attitude of the drone detected by the inertial unit and characterized by a corresponding variation of said at least one Euler angle. - the digital sensor is a scanning sensor delivering said raw pixel data line by line; - the drone further includes means for extracting a fraction of the pixels from the image formed on the sensor, these extractor means: • receiving as an input a selection signal defining over the sensor extent the position of a capture area of reduced size, and • transferring to said image processing means, for compensation for the geometric distortions, only said raw pixel data corresponding to the capture area of reduced size; • receiving as an input a selection signal defining over the sensor extent the position of a capture area of reduced size, and • transferring to said image processing means, for compensation for the geometric distortions, only said raw pixel data corresponding to the capture area of reduced size; - the automatic control means are means adapted to modify dynamically said selection signal, defining the extent of said capture area of the extractor means, in a direction opposite to that of a change of attitude of the drone detected by the inertial unit and characterized by a corresponding variation of said at least one Euler angle.
