Abstract

To realize a change in a volume that does not give a user a feeling of strangeness even when a great processing load is put on a volume determining unit. A volume controller performs a process for determining a new volume of an audio signal based on an alternate pulse interval that is based on a counting time and the number of pulses counted by a counting section within the counting time and a current volume stored in a storage section, and storing the determined new volume as the current volume in the storage section, the same number of times as the number of pulses counted by the counting section every counting time, and outputs last information stored as the current volume in the storage section to an electronic volume.

First claim

What is claimed is:

1. A quantity adjusting apparatus comprising:
an operating section for instructing a quantity of a subject to be adjusted;
a pulse output section for outputting a pulse according to an operating speed of the operating section;
a storage section for storing a current quantity of the subject to be adjusted;
a counting section for counting a number of the pulses output from the pulse output section within a counting time;
a quantity controller for performing a process for determining a new quantity of the subjects to be adjusted based on a pulse interval that is an interval of an output start time of the two pulses and the current quantity stored in the storage section and storing the determined new quantity as the current quantity in the storage section, the same number of times as the number of the pulses counted by the counting section every counting time and for outputting last information stored as the current quantity in the storage section; and
a quantity changing section for changing the quantity of the subject to be adjusted based on information about the current quantity output from the quantity controller, wherein
the quantity controller uses an alternate pulse interval that is based on the counting time and the number of pulses counted by the counting section within the counting time as the pulse interval.

2. The quantity adjusting apparatus according to claim 1 , wherein the quantity controller divides the counting time by the number of pulses counted by the counting section, to calculate the alternate pulse interval.

3. The quantity adjusting apparatus according to claim 1 , wherein when a value obtained by dividing the counting time by the number of pulses counted by the counting section is a value after a decimal point, the quantity controller adjusts the divided value to an integer and calculates the alternate pulse interval.

4. The quantity adjusting apparatus according to claim 1 , wherein the subject to be adjusted is an audio signal, and the quantity is a volume.
