Computer-readable program, audio controller, and wireless audio system
First Claim
1. A program readable by a computer, for causing the computer to function as an audio controller,the program stored on a non-volatile memory comprising:
- output characteristic storage means for storing an output characteristic of a playback signal for each usage environment of a speaker;
picked-up image data acquisition means for acquiring picked-up image data on an installation area of the speaker, which includes the speaker;
usage environment identification means for identifying the usage environment of the speaker based on the picked-up image data acquired by the picked-up image data acquisition means; and
output characteristic determination means for determining an output characteristic stored in the output characteristic storage means in association with the usage environment identified by the usage environment identification means, as the output characteristic of the playback signal to be output from the speaker;
wherein the picked-up image data acquisition means is configured to acquire, as first picked-up image data, picked-up image data obtained by picking up an image of the installation area of the speaker so that boundaries on both sides of a wall behind the speaker are aligned with both edges of an angle of view, andwherein the usage environment identification means is configured to obtain a ratio between a width of the wall behind the speaker and a width of the speaker from the first picked-up image data, and to identify, as the usage environment of the speaker, a size of the installation area of the speaker based on the ratio.

Abstract
To provide a technology capable of changing an output characteristic of music data more efficiently with a simpler operation irrespective of whether or not the music data is being played back, an audio controller (2) identifies a usage environment of a wireless speaker (1) from picked-up image data on an installation room of the wireless speaker (1). Then, an output characteristic suitable for the identified usage environment is selected, and the selected output characteristic is set as an output characteristic of music data to be output from the wireless speaker (1). In this case, a ratio between a width of a wall behind the wireless speaker (1) and a width of the speaker is obtained from the picked-up image data obtained by picking up an image of the installation room of the wireless speaker (1) so that boundaries between the wall behind the wireless speaker (1) and both sides thereof are aligned with both edges of an angle of view, and a size of the installation room of the wireless speaker (1) is identified based on this ratio to be used as the usage environment. Further, an installation position of the speaker is identified based on a display position of the speaker in the picked-up image data to be also used as the usage environment.
