VOLUME INDICATION CONTROL DEVICE AND VOLUME INDICATION CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To indicate a volume indication value approximate to an actual volume value even when the volume value is changed at an accelerating pace.;SOLUTION: Whether a difference between the volume value and the volume indication value is greater than a first prescribed value or not is determined in every prescribed time, and if the difference is greater, the variation to change the volume indication value is made to increase according to the difference between the volume value, and the volume indication value. The fresh variation is added to the present volume indication value to calculate the fresh volume indication value and is displayed in a display element. Accordingly, if the difference between the volume value, and the volume indication value is above the prescribed value, and is relatively great, the variation of the volume indication value is greatly increased. If the difference between the volume value, and the volume indication value is above the prescribed value, or is relatively small, the variation of the volume indication value is slightly increased. If the difference between the volume value, and the volume indication value is below the prescribed value, the variation is not increased.;COPYRIGHT: (C)2009,JPO&INPIT
