In a range imaging camera, a first range image producing unit produces a first range image by calculating a distance to an object on the basis of the delay time or the received light amount of each pixel produced by a light receiving processing unit. A second range image producing unit produces a second range image by performing filtering for each pixel of the first range image using a group of neighboring pixels including its own pixel. In this case, a pixel group selection unit selects a group of pixels used in the filtering such that at least one of produced values including the delay time and the received light amount produced by the light receiving processing unit and the first range image produced by the first range image producing unit is equal to or larger than a noise component value.
