Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for dynamically determining an exposure time for capturing an image implemented with a drone having a substantially vertical view.SOLUTION: The method comprises a step 21 of measuring the horizontal speed of displacement of the drone, a step 22 of measuring a distance (Z) between the drone and the ground, and a step 23 of determining the duration of exposure based on the measured speed of displacement of the drone, the distance (Z) measured between the drone and the ground, a predetermined quantity of blurring (du) and the focal length (f) of a camera.SELECTED DRAWING: Figure 2 【課題】実質的に鉛直視のカメラを有するドローンで実施される画像の撮像のための露出時間を動的に決定する方法を提供する。【解決手段】ドローンの水平変位速度を測定するステップ２１と、ドローンと地面との間の距離（Ｚ）を測定するステップ２２と、ドローンの測定された変位速度と、ドローンと地面との間の測定された距離（Ｚ）と、予め定められたぼかし量（ｄｕ）と、カメラの焦点距離（ｆ）とに基づいて、露出時間を決定するステップ２３を備える。【選択図】図２
