Zusammenfassung:	A distance camera includes at least one photo element, a trigger generator activating the photo element during a temporal integration gate, a light source illuminating an object with light pulses having a predetermined temporal intensity profile with a duration Tp, and an intensity sensor determining the intensity Ip of the light pulses arriving on the photo element. The integration gate has a predetermined delay to the light pulse emission start point in order to capture the light pulses back reflected from the object. The photo element outputs a signal value U at an integration end point in time T1e and in accordance with an intensity Ip and a duration of the light pulse arriving on the photo element during its activation.
