Abstract
Disclosed is an image pickup apparatus 100 including a sound obtaining section 6 to obtain a sound emitted from the main subject and a central control section 71 to specify an image region of the main subject based on the sound obtained by the sound obtaining section 6 in order to specify the image region of the main subject from an obtained image.
Claims13
An apparatus to detect a main subject from an obtained image, comprising:
- an image obtaining unit which obtains the image including the main subject;
- a sound obtaining unit which obtains a sound emitted from the main subject;
- and
- a main subject detection unit which detects an image region of the main subject in the image based on the image obtained by the image obtaining unit and the sound obtained by the sound obtaining unit;
- wherein the main subject detection unit comprises:
- a determination unit which determines whether or not the sound obtained by the sound obtaining unit has at least a predetermined volume;
- a detection information specification unit which specifies sound related information for detecting the main subject based on the sound obtained by the sound obtaining unit, when the determination unit determines that the sound has at least the predetermined volume;
- a first detection unit which detects the image region of the main subject in the image based on the image obtained by the image obtaining unit and the sound related information specified by the detection information specification unit, when the determination unit determines that the sound has at least the predetermined volume;
- and
- a second detection unit which detects the image region of the main subject in the image based on the image obtained by the image obtaining unit, and not based on any sound related information specified by the detection information specification unit, when the determination unit determines that the sound does not have at least the predetermined volume.

A method of detecting a main subject of an image, comprising:
- controlling an image obtaining unit to obtain the image including the main subject;
- controlling a sound obtaining unit to obtain a sound emitted from the main subject;
- and
- detecting an image region of the main subject in the obtained image based on the image obtained by the image obtaining unit and the sound obtained by the sound obtaining unit;
- wherein the detecting the image region of the main subject in the obtained image comprises:
- determining whether or not the sound obtained by the sound obtaining unit has at least a predetermined volume;
- specifying sound related information for detecting the main subject based on the sound obtained by the sound obtaining unit, when it is determined that the sound has at least the predetermined volume;
- detecting the image region of the main subject in the image based on the image obtained by the image obtaining unit and the specified sound related information, when it is determined that the sound has at least the predetermined volume;
- and
- detecting the image region of the main subject in the image based on the image obtained by the image obtaining unit, and not based on any specified sound related information, when it is determined that the sound does not have at least the predetermined volume.

A non-transitory computer-readable medium having stored thereon a program which controls a computer to detect a main subject of an obtained image by performing functions comprising:
- controlling an image obtaining unit to obtain the image including the main subject;
- controlling a sound obtaining unit to obtain a sound emitted from the main subject;
- and
- detecting an image region of the main subject in the obtained image based on the image obtained by the image obtaining unit and the sound obtained by the sound obtaining unit;
- wherein the detecting the image region of the main subject in the obtained image comprises:
- determining whether or not the sound obtained by the sound obtaining unit has at least a predetermined volume;
- specifying sound related information for detecting the main subject based on the sound obtained by the sound obtaining unit, when it is determined that the sound has at least the predetermined volume;
- detecting the image region of the main subject in the image based on the image obtained by the image obtaining unit and the specified sound related information, when it is determined that the sound has at least the predetermined volume;
- and
- detecting the image region of the main subject in the image based on the image obtained by the image obtaining unit, and not based on any specified sound related information, when it is determined that the sound does not have at least the predetermined volume.
