The invention provides a filtering device that can appropriately derive a difference value of an object by evaluating relative positional relationships of reference blocks and relative positional relationships of comparison blocks. When a positional relationship between reference blocks differs from a positional relationship between comparison blocks, a filtering device replaces the corresponding comparison blocks to update positional relationship information (order of correlations and the positional relationship thereof) into a state where the information should be and, thus, appropriately derives a difference value of an object so that the positional relationship between the reference blocks become identical to the positional relationship between the comparison blocks.
