Abstract
A photon detecting 3D imaging sensor device for detecting a distance information for pixels in an image includes an array of detector units. Each detector unit is configured to receive a light signal pulse and to provide a detection signal pulse on receipt of the light signal pulse. The 3D imaging device further includes a pulse selection unit including a decision tree with one or more stages. Each of the stages has one or more decision makers which are cascaded to propagate the earliest detection signal pulse of one of a respective detector unit as a timing signal. The 3D imaging device further includes a time-to-digital converter configured to receive the timing signal and to provide a time stamp depending on the timing signal. The time stamp indicates the distance information for a pixel of the image.
