Abstract: An input interface acquires a first distance image including a plurality of pixels, each of the plurality of pixels indicating a distance value from an image capture device to each point of an object. An image divider divides the first distance image into a plurality of pixel groups based on the distance values of the pixels, such that each of the plurality of pixel groups includes pixels having distance values falling within one of a plurality of distance intervals different from each other. A noise filter individually processes the plurality of pixel groups using a plurality of filter parameters different for the plurality of pixel groups, to reduce noises in the plurality of pixel groups. An image combiner combines the plurality of pixel groups processed by the noise filter, with each other, to generate a second distance image.
