Abstract

A display control apparatus includes an acquisition unit configured to acquire information about directivity of a sound collection unit that collects sound from a sound-collection target area, and a control unit configured to cause a display unit to display a display image in which an area image and a range image are superimposed on one another, the area image representing the sound-collection target area, and the range image having a shape expressing a sound collection range according to the directivity of the sound collection unit identified by the information acquired by the acquisition unit and representing loudness of sound in the sound collection range.

Claims

1. A display control apparatus comprising:

one or more hardware processors; and

one or more memories which store instructions executable by the one or more hardware processors to cause the display control apparatus to perform at least;

acquiring information about directivity of a microphone that collects sound from a sound-collection target area; and

controlling to cause a display unit to display a superimposed image in which an area image and a range image are superimposed on one another, the area image representing the sound-collection target area, and the range image having a shape representing a sound collection range according to the directivity of the microphone identified by the acquired information and the range image representing loudness of sound in the sound collection range.

2. The display control apparatus according to claim 1, wherein the controlling includes causing the display to display the superimposed image in which the area image, the range image, and a sound collection unit image representing a position of the microphone are superimposed on one another.

3. The display control apparatus according to claim 2, wherein the controlling includes determining a color of the sound collection image based on the loudness of sound in the sound collection range.

4. The display control apparatus according to claim 2, wherein the controlling includes determining a size of a part to be colored in the sound collection unit image based on the loudness of sound in the sound collection range.

5. The display control apparatus according to claim 2, wherein the sound collection unit image indicates both the position of the microphone and the orientation of the microphone.

6. The display control apparatus according to claim 1, wherein the controlling includes determining the shape of the range image based on a directional beam pattern of the sound collection, with reference to an orientation of the microphone.

7. The display control apparatus according to claim 1, wherein the controlling includes determining the shape of the range image based on an angle formed by a direction of a directional beam pattern of the microphone and a plane of the sound-collection target area.

8. The display control apparatus according to claim 1, wherein the controlling includes determining the shape of the range image based on an attenuation of sound collection sensitivity according to a distance from the microphone.

9. The display control apparatus according to claim 1, wherein the loudness of sound in the sound collection range is loudness of sound obtained by normalizing loudness of sound collected by the microphone by using a predetermined gain adjustment amount.

10. The display control apparatus according to claim 1, wherein the loudness of sound in the sound collection range is loudness of sound obtained by normalizing loudness of sound collected by the microphone by using an area of the sound collection range.

11. The display control apparatus according to claim 1, wherein the loudness of sound in the sound collection range is loudness of sound obtained by normalizing loudness of sound collected by the microphone by using a distance between the sound collection unit and the microphone.

12. The display control apparatus according to claim 1, wherein the controlling includes determining a color of the range image based on the loudness of sound in the sound collection range.

13. The display control apparatus according to claim 1, wherein the controlling includes determining a size of a part to be colored in the range image based on the loudness of sound in the sound collection range.

14. The display control apparatus according to claim 1, wherein the acquiring includes acquiring information about directivity of each of a plurality of microphones that collect sound from the sound-collection target area, and

wherein the controlling includes causing the display to display the superimposed image in which the area image and a plurality of range images corresponding to the plurality of microphone are superimposed on one another.

15. The display control apparatus according to claim 14, wherein the controlling includes causing the display to display the superimposed image in which the area image, the plurality of range images, and a plurality of sound collection images representing positions of the plurality of microphones are superimposed on one another.

16. The display control apparatus according to claim 15, wherein the controlling includes bringing a first range image corresponding to a first microphone, and a first sound collection image corresponding to the first microphone into correspondence with each other, in terms of at least one of a color, a line type, and a thickness of a line forming each of the range image and the sound collection image.

17. A display control method comprising:

acquiring information about directivity of a sound collection unit that collects sound from a sound-collection target area; and

performing control for causing a display unit to display a superimposed image in which an area image and a range image are superimposed on one another, the area image representing the sound-collection target area, and the range image having a shape representing a sound collection range according to the directivity of the sound collection unit identified by the acquired information and representing loudness of sound in the sound collection range.

18. The display control method according to 17, wherein the controlling causes the display unit to display the superimposed image in which the area image, the range image, and a sound collection unit image representing a position of the sound collection unit are superimposed on one another.

19. The display control method according to 17, wherein the loudness of sound in the sound collection range is loudness of sound obtained by normalizing loudness of sound collected by the sound collection unit by using a predetermined gain adjustment amount.

20. A non-transitory computer readable storage medium storing a program for causing a computer to execute a display control method, the display control method comprising:

acquiring information about directivity of a sound collection unit that collects sound from a sound-collection target area; and

performing control for causing a display unit to display a superimposed image in which an area image and a range image are superimposed on one another, the area image representing the sound-collection target area, and the range image having a shape representing a sound collection range according to the directivity of the sound collection unit identified by the acquired information and representing loudness of sound in the sound collection range.
