A sensor device (10) for photon-based imaging, comprising: one or more photon detectors for generating a plurality of photon detection signals in response to a plurality of photon detection events, where each photon detection event has a respective detection time, and where each photon detection event has a respective detection time; the detection times of the plurality of photon detection events are distributed over time; and processing circuitry to perform a generalization process with timing information for the plurality of photon detection events to obtain a compressed representation of the temporal distribution, where the generalization process comprises: generating a plurality of feature values with one or more feature functions according to the timing information for the plurality of photon detection events; combining the generated plurality of feature values to obtain the compressed representation of the temporal distribution, where the feature function has one or more characteristics, and where the c
