Abstract

A communication device for communicating with an external is connectable to a navigation apparatus. The navigation apparatus includes a display portion, an input portion for inputting memo information, an outgoing/incoming call determination portion, and a display control portion for controlling the display portion. The outgoing/incoming call determination portion determines whether or not the communication portion conducts an outgoing call and determining whether the communication portion receives an incoming call. When the outgoing/incoming call determination portion concludes that the communication portion conducts the outgoing call or that the communication portion receives the incoming call, the display control portion splits the display portion into a memo screen on which content of the memo information is displayed and a navigation screen.

Claims

1. A navigation apparatus to which a communication device for communicating with an external is connectable, the navigation apparatus comprising:

a display portion;

an input portion for inputting memo information;

an outgoing/incoming call determination portion for determining whether the communication portion conducts an outgoing call and determining whether the communication portion receives an incoming call; and

a display control portion for controlling the display portion,

wherein when the outgoing/incoming call determination portion concludes that the communication portion conducts the outgoing call or that the communication portion receives the incoming call, the display control portion splits the display portion into a memo screen on which content of the memo information is displayed and a navigation screen.

2. The navigation apparatus according to claim 1, further comprising:

a memo input processing portion for conducting a predetermined process based on a predetermined input signal from the input portion.

3. The navigation apparatus according to claim 2, wherein the predetermined process includes a process for starting to take notes on the memo screen and a process for terminating to take notes on the memo screen.

4. The navigation apparatus according to claim 1, wherein the input portion includes a touch panel for drawing the memo information on the memo screen in accordance with a touch operation,

the navigation apparatus further comprising:

a character recognition portion for recognizing the memo information drawn on the memo screen as character data;

a memo information storage portion; and

a first storage control portion for storing the character data recognized by the character recognition portion into the memo information storage portion.

5. The navigation apparatus according to claim 4, wherein the display control portion display the character data recognized by the character recognition portion on the memo screen.

6. The navigation apparatus according to claim 1, wherein the input portion includes a voice acquiring portion for acquiring voice as voice data,

the navigation apparatus further comprising:

a voice recognition portion for recognizing as character data the voice data acquired by the voice acquiring portion and voice data received by the communication portion;

a memo information storage portion; and

a second storage control portion for storing the character data recognized by the voice recognition portion into the memo information storage section.

7. The navigation apparatus according to claim 5, wherein the display control portion display the character data recognized by the voice recognition portion on the memo screen.

8. The navigation apparatus according to claim 6, further comprising:

a memo input processing portion for conducting a predetermined process based on a predetermined input signal from the input portion; and

an operation keyword registration portion for registering an operation keyword,

wherein when the voice data acquired by the voice acquiring portion coincides with the operation keyword, the memo input processing portion conducts the predetermined process.

9. The navigation apparatus according to claim 8, wherein the operation keyword registration portion registers the operation keyword for each other person in communication individually.

10. The navigation apparatus according to claim 4, further comprising:

a character-extraction keyword registration portion for registering a character extraction keyword utilized for extracting a predetermined character data from the character data recognized by the character recognition portion.

11. The navigation apparatus according to claim 6, further comprising:

a character-extraction keyword registration portion for registering a character extraction keyword utilized for extracting a predetermined character data from the character data recognized by the voice recognition portion.

12. The navigation apparatus according to claim 10, wherein the character-extraction keyword registration portion registers the character extraction keyword for each other person in communication individually.

13. The navigation apparatus according to claim 11, wherein the character-extraction keyword registration portion registers the character extraction keyword for each other person in communication individually.

14. The navigation apparatus according to claim 10, further comprising:

a character data extraction portion for extracting a predetermined character data from the character data based on the character extraction keyword; and

a character data registration portion for registering the extracted character data by the character data extraction portion in a predetermined data base.

15. The navigation apparatus according to claim 11, further comprising:

a character data extraction portion for extracting a predetermined character data from the character data based on the character extraction keyword; and

a character data registration portion for registering the extracted character data by the character data extraction portion in a predetermined data base.

16. The navigation apparatus according to claim 14, wherein the character data registration portion includes:

an update information determination portion for determining whether update information relating to the predetermined data base is contained in the predetermined character data extracted by the character data extraction portion; and

an update information registration portion for registering the update information in the predetermined data base when the update information determination portion concludes that the update information is contained.

17. The navigation apparatus according to claim 15, wherein the character data registration portion includes:

an update information determination portion for determining whether update information relating to the predetermined data base is contained in the predetermined character data extracted by the character data extraction portion; and

an update information registration portion for registering the update information in the predetermined data base when the update information determination portion concludes that the update information is contained.

18. The navigation apparatus according to claim 14, further comprising:

a character data correction portion for correcting the character data registered in the predetermined data base by the character data registration portion, desirably.

19. The navigation apparatus according to claim 15, further comprising:

a character data correction portion for correcting the character data registered in the predetermined data base by the character data registration portion, desirably.
