Focusing a camera capturing video data using directional data of audio

A focus determiner for focusing a camera capturing video data, the focus determiner comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the focus determiner to:
• obtain audio data and video data, comprising a plurality of sequential images, wherein the audio data and video data overlap in time and cover the same scene;
• determine directional data of a dominant sound source in the audio data;
• match a visual feature spatially, in an image of the plurality of sequential images of the video data, with the directional data, wherein the image corresponds to the directional data in time;
• and
• focus a camera, being the source of the video data, to focus on the visual feature for subsequent capturing of video data.

A computer program for focusing a camera capturing video data, the computer program comprising computer program code which, when executed on a focus determiner causes the focus determiner to:

• obtain audio data and video data, comprising a plurality of sequential images, wherein the audio data and video data overlap in time and cover the same scene;
• determine directional data of a dominant sound source in the audio data;
• match a visual feature spatially, in an image of the plurality of sequential images of the video data, with the directional data, wherein the image corresponds to the directional data in time;
• and
• focus a camera, being the source of the video data, to focus on the visual feature for subsequent capturing of video data.
