Abstract: An indirect time-of-flight measurement sensor includes a photosensitive pixel array configured to acquire a succession of images of a scene during a given exposure time. The sensor includes a control unit configured to control the acquisition of the succession of images by the pixel array and to define an exposure time for this acquisition based on a pixel saturation rate of the array, distances between the sensor and elements of the scene, and a standard deviation of the distances between the sensor and the elements of the scene.
