PROBLEM TO BE SOLVED: To provide a parameter control device, a parameter control program and a mobile phone, capable of promptly controlling a parameter such as a volume value of an audio device to a desired value.SOLUTION: The parameter control device detects a long-time operation, a continuous operation of an operation target unit that exceeds a first predetermined time, and also detects a plurality of times of repeated operations of the operation target unit that are performed in repetition at intervals within a second predetermined times, and the number of the repeated operations, that is, the number of times of operations performed in repetition. If the long-time operation is detected, parameter update processing is performed in repetition while the long-time operation is performed. If the long-time operation is performed at the last operation of the repeated operations, the parameter control device determines one or both of a step value of the parameter update processing and the repetition interval of the parameter update processing, on the basis of the number of repeated operations. |
