Abstract: The timing when the operation state of an operation unit is changed is detected by a timing detection unit. A difference between a sound signal on which operation sound is superimposed or is highly likely to be superimposed and a sound signal on which operation sound is not superimposed is calculated based on the timing signal to obtain the operation sound information of the operation unit.
