Abstract
A filtering device () includes an acquirer () and a filtering unit (). The acquirer () acquires an input value that is repeatedly input. The filtering unit () obtains an output value by filtering for reduction of noise included in the input value. When a difference between the current input value and the past output value exceeds a first threshold, the filtering unit () obtains a new output value by weighting the current input value with a weight greater than a weight for obtaining the past output value.
