Abstract:
A direction detection apparatus is disclosed. The direction detection apparatus includes a distribution obtainment section, an emphasis section, and a direction selection section. The distribution obtainment section obtains a distribution of intensities of sounds in a predetermined directional range. The emphasis section emphasizes sounds in the distribution of the intensities of the sounds obtained by the distribution obtainment section, wherein the emphasis section emphasizes the sounds in a second directional range which is a narrower directional range than the predetermined directional range and a center of the second directional range corresponds to a direction represented by selection information. The direction selection section decides a direction to be selected next based on the distribution of the intensities of the sounds which are output from the emphasis section and outputs the direction decided to be selected next as the selection information.
