Abstract
A sound pickup device includes a plurality of microphones, and at least one processor configured to implement stored instructions and execute a plurality of tasks, including: a first gain controlling task controlling a gain of each of the plurality of microphones, an adding task adding a sound signal to be output from the first gain controlling task with a predetermined gain, a second gain controlling task controlling a gain of the sound signal to be output from the adding task; and a gain setting task setting each gain of the first gain controlling task based on gain setting in the second gain controlling task.
Claims20
A sound pickup device, comprising:
- a plurality of microphones;
- and
- at least one processor configured to implement stored instructions and execute a plurality of tasks, including:
- a first gain controlling task controlling a first gain of each of the plurality of microphones;
- an adding task adding a sound signal to be output from the first gain controlling task with a predetermined gain;
- a second gain controlling task controlling a gain of the sound signal to be output from the sound pickup device;
- and
- a gain setting task setting each first gain of the first gain controlling task based on gain setting in the second gain controlling task.
A sound pickup device, comprising:
- a plurality of microphones;
- a first gain controller controlling a first gain of each of the plurality of microphones;
- an adder adding a sound signal to be output from the first gain controller with a predetermined gain;
- a second gain controller controlling a second gain of the sound signal to be output from the adder;
- and
- a gain setter setting each first gain of the first gain controller based on gain setting in the second gain controller.
A sound pickup method comprising the steps of:
- picking up sound by each of a plurality of microphones;
- controlling a first gain of each of the plurality of microphones in a first gain controller;
- adding each sound signal that has been controlled in the first gain controller, in an adder, with a predetermined gain;
- controlling a second gain of the sound signal that has been added in the adder, in a second gain controller;
- and
- setting gain setting in the first gain controller based on gain setting in the second gain controller, in a gain setter.
