Provided are a computer system, a drone control method, and a program that can obtain information about the object while reducing the power consumption. When the computer system acquires an image captured by a drone, the computer system performs image analysis on the acquired image, extract, in a result of the image analysis, a point whose an edge variation amount is equal to or greater than a predetermined threshold, acquires a position coordinate of the extracted point; and controls the drone to fly towards the acquired position coordinate and perform capturing with a camera using light other than visible light.
