To determine a criticality limit, the image is divided into N image areas (120), a Shapley value is calculated for each of the N image areas, and the N image areas are sorted according to importance based on the Shapley value. Starting with the most important image area, a progressively less important image area is removed (130), and an object classification is performed for each remaining image. This is repeated until the object classification for an i-th remaining image yields no result (140), and the criticality limit is determined using a divisor i / N and averaging over several images.During a test drive, a standard criticality threshold is established. During a standard drive, a current criticality threshold is continuously calculated.
