    Abstract: Reinterpretable cameras are defined by their
    post-processing capabilities that exceed traditional imaging. We
    present "SoDaCam" that provides reinterpretable cameras at the
    granularity of photons, from photon-cubes acquired by
    single-photon devices. Photon-cubes represent the spatio-temporal
    detections of photons as a sequence of binary frames, at
    frame-rates as high as 100 kHz. We show that simple
    transformations of the photon-cube, or photon-cube projections,
    provide the functionality of numerous imaging systems including:
    exposure bracketing, flutter shutter cameras, video compressive
    systems, event cameras, and even cameras that move during
    exposure. Our photon-cube projections offer the flexibility of
    being software-defined constructs that are only limited by what
    is computable, and shot-noise. We exploit this flexibility to
    provide new capabilities for the emulated cameras. As an added
    benefit, our projections provide camera-dependent compression of
    photon-cubes, which we demonstrate using an implementation of our
    projections on a novel compute architecture that is designed for
    single-photon imaging.
