Abstract

A map drawing apparatus has a map information reading section, a level extracting section, and a map information processing section. The map information reading section reads map information. The level extracting section extracts a level of a spectrum over a predetermined frequency range from a signal of input sound. The map information processing section processes the form (height, color, shape) of an object (a building, a cloud in the background, or the like) contained in the map information read by the map information reading section, into map information dynamically changed in cooperation with the spectrum extracted by the level extracting section. The map information processing section converts the processed map information into an image signal that can be displayed on a display device.

Claims

1. A map drawing apparatus comprising:

a map information obtaining section which obtains map information from a map information database;

a level extracting section which extracts a level of a spectrum over a predetermined frequency range from a signal of sound inputted from a sound source;

an inputting section via which a user designates a predetermined item;

a map information processing section which processes the obtained map information into map information in which a form of a predetermined object contained in the obtained map information dynamically changes in cooperation with the extracted spectrum level and with the item designated by the user; and

a converting section which converts the processed map information into an image signal, which can be displayed on a display device,

wherein the map information processing section allocates divisions of the map information to spectra of the input sound.

2. The map drawing apparatus according to claim 1, wherein the map information processing section allocates divisions of the map information to spectra of left and right channels of the input sound.

3. The map drawing apparatus according to claim 2,

wherein the divisions of the map information are two display regions, which are separated across a road on which an own vehicle is travelling;

wherein the left channel of the input sound is allocated to one of the display regions; and

wherein the right channel of the input sound is allocated to the other of the display regions.

4. The map drawing apparatus according to claim 2,

wherein the divisions of the map information are display regions obtained by dividing a display screen of the display device;

wherein the display regions display a plurality of map information;

wherein the left channel of the input sound is allocated to one of the display regions; and

wherein the right channel of the input sound is allocated to the other of the display regions.

5. The map drawing apparatus according to claim 1, wherein the map information processing section allocates divisions of the map information to spectra of high-frequency range and low-frequency range of the input sound.

6. The map drawing apparatus according to claim 5,

wherein the divisions of the map information are a region displaying a side close to a road on which an own vehicle is travelling and a region displaying a side remote from the road;

wherein the high-frequency range of the input sound is allocated to one of the display regions; and

wherein the low-frequency range of the input sound is allocated to the other of the display regions.

7. The map drawing apparatus according to claim 5,

wherein the divisions of the map information are a region displaying a distant view of a displayed map and a region displaying a close view of the map;

wherein the high-frequency range of the input sound is allocated to one of the display regions; and

wherein the low-frequency range of the input sound is allocated to the other of the display regions.

8. The map drawing apparatus according to claim 1, wherein the object is displayed in a form of a wire frame image.

9. The map drawing apparatus according to claim 1, wherein a graphic equalizer is superimposedly displayed in a vacant display region of a background.

10. The map drawing apparatus according to claim 1, wherein the predetermined object is a structure.

11. The map drawing apparatus according to claim 1, wherein the form is at least one of height, color and shape.

12. The map drawing apparatus according to claim 1, where the sound is music.
