According to a method for distance measurement, light is emitted and a reflected part is detected. A first and a second energy value (E2) of the reflected part detected during a first and a second measurement interval (21a, 22a, 23a, 24a) are determined, wherein a duration of the measurement intervals (21a, 22a, 23a, 24a) is given by an integration time and the first energy value (E1) fulfils a predefined saturation condition. A first further energy value (E1 ') of the reflected part detected during a first further measurement interval (26a, 27a, 28a, 29a) is determined, whose duration is shorter than the integration time. An energy value for the first measurement interval (21a, 22a, 23a, 24a) is estimated depending on the first further energy value (E1 ') and a distance is determined depending on the estimated energy value (eE1) and the second energy value (E2).
