Claim:
1. A time-of-flight camera, comprising: a photosensor and a reference photosensor, each of the photosensors having accumulation gates and being configured as a photomixing detector (PMD); and a readout device connected to the accumulation gates of the photosensor and to the accumulation gates of the reference photosensor, wherein the readout device is configured to read out an electric quantity that corresponds to a charge that is present at respective ones of the accumulation gates, wherein the time-of-flight camera is configured to set, in a calibration phase, an integration time for accumulating charges based on the reference photosensor in that the integration time is dimensioned so as to prevent every pixel of the reference photosensor from reaching saturation during operation of the time-of-flight camera, the integration time being the same for every pixel of the photosensor and for every pixel of the reference photosensor.
