A time of flight (TOF) camera comprises a light source for illuminating an object with light and a plurality of light-sensitive pixels for collecting return image light reflected by the object. Further, each light-sensitive pixel of the TOF camera may comprise a photoelectric cathode for generating electrons responsive to return image light incident on the pixel and a plurality of anodes for collecting electrons generated at the photoelectric cathode.
