Abstract
A sound collection direction is decided based upon an area of an object in a captured image obtained by image capturing of a periphery and a sound collection target position input as a position of a sound collection target. A noise direction is decided based upon an arrangement of the object in the captured image. A sound collected from the periphery is separated into a sound in the sound collection direction and a sound in the noise direction, and noise canceling on the sound in the sound collection direction is performed using the sound in the noise direction.
Claims11
A sound collection apparatus comprising:
- a first decision unit configured to decide a sound collection direction based upon an area of an object in a captured image obtained by image capturing of a periphery and a sound collection target position input as a position of a sound collection target;
- a second decision unit configured to decide a noise direction based upon an arrangement of the object in the captured image;
- and
- a noise canceling unit configured to separate a sound collected from the periphery into a sound in the sound collection direction and a sound in the noise direction, and perform noise canceling on the sound in the sound collection direction using the sound in the noise direction.
A method of controlling a sound collection apparatus, the method comprising:
- deciding a sound collection direction based upon an area of an object in a captured image obtained by image capturing of a periphery and a sound collection target position input as a position of a sound collection target;
- deciding a noise direction based upon an arrangement of the object in the captured image;
- and
- separating a sound collected from the periphery into a sound in the sound collection direction and a sound in the noise direction, and performing noise canceling on the sound in the sound collection direction using the sound in the noise direction.
A non-transitory computer-readable storage medium storing a computer program for causing a computer to function as:
- a first decision unit configured to decide a sound collection direction based upon an area of an object in a captured image obtained by image capturing of a periphery and a sound collection target position input as a position of a sound collection target;
- a second decision unit configured to decide a noise direction based upon an arrangement of the object in the captured image;
- and
- a noise canceling unit configured to separate a sound collected from the periphery into a sound in the sound collection direction and a sound in the noise direction, and perform noise canceling on the sound in the sound collection direction using the sound in the noise direction.
