Abstract: There is provided in accordance with an aspect of the presently disclosed subject matter a range imaging camera including a light source configured to emit a modulated light pulse towards an object; a shutter configured to modulate the portion of the light pulse with a modulation corresponding to the modulated light pulse; a detector having an array of photodiodes each of which being configured to detect a portion of the light pulse reflected from the object and transmitted through the shutter and to generate a signal, wherein the detector is configured to output a plurality of differential signals each of which being obtained by determining a difference between two signals generated by two adjacent photodiodes; and a controller configured for calculating distance between the light source and the object in accordance to the differential signals.
