By inserting an SD card or USB memory storing map information into these slots, the control unit 20 reads the map information from the SD card or USB memory and outputs the map information to the navigation unit 19.

  When the portable device 10 is mounted on the in-vehicle device 100, the power source of the portable device 10 is turned on / off under the control of the in-vehicle device 100. Further, when the portable device 10 is used alone after being detached from the in-vehicle device 100, the power is operated based on the on / off operation of the power button 55.

  Furthermore, on the back side of the portable device 10, a connector 30 for making an electrical connection with the in-vehicle device 100, and an engagement portion 58 that engages with a lock mechanism (not shown) provided on the in-vehicle device 100 side. Is provided.

  Details of the first embodiment will be described below. FIG. 9 is a block diagram in which main blocks are extracted from FIG. 5 and described in detail with a focus on the control unit 140 of the in-vehicle device 100. Referring to FIG. 9, the control unit 140 includes an image processing unit 200 (image processing unit), a display method detection unit 204 (display method detection unit), and a data method detection unit 202 (data method detection unit). The display method detection unit 204 detects an image method that can be displayed on the portable device 10 and outputs display method information to the image processing unit 200. The data method detection unit 202 detects the data method from, for example, DVD playback image data, and outputs the data method information to the image processing unit 200. The image processing unit 200 transmits the image data to the portable device 10 without conversion or conversion based on the display method information and the data method information.

  FIG. 10 is a flowchart showing the control performed by the control unit 140. Referring to FIG. 10, when the portable device 10 is mounted and image data is input to the control unit 140, the display method detection unit 204 informs the control unit 20 of the portable device 10 whether the display method is NTSC method or PAL method. Information (display method information) is requested, and the display method information of the portable device 10 is acquired from the display method detection unit 204 (step S10). Upon receiving a request for display method information from the control unit 140, the control unit 20 reads the display method information from the memory 18 such as a non-volatile memory, and transmits the display method information to the display method detection unit 204. The display method detection unit 204 outputs display method information to the image processing unit 200. As a result, the image processing unit 200 can acquire the display method information of the portable device 10 from the display method detection unit 204.

  When the image data is input to the control unit 140, the data method detection unit 202 detects whether the data method is the NTSC method or the PAL method from the image data. The data method detection unit 202 outputs information on whether the data method is the NTSC method or the PAL method (data method information) to the image processing unit 200. As a result, the image processing unit 200 can acquire the data method information of the image data from the data method detection unit 202 (step S12).

  The image processing unit 200 determines whether the display method can be the NTSC method, the PAL method, or the NTSC method and the PAL method based on the display method information (step S14). When the display method is the NTSC method, the image processing unit 200 determines whether the data method of the image data is the NTSC method or the PAL method based on the data method information (step S16). When the data method is the PAL method, the image processing unit 200 converts the image data to the NTSC method (step S18), and transmits the image data to the portable device 10 (step S30). If the data system is the NTSC system in step S16, the image processing unit 200 does not convert the data system of the image data (step S20), and transmits it to the portable device 10 in the NTSC system (step S30).

  In step S14, in the case of the PAL method, the image processing unit 200 determines whether the data method of the image data is the NTSC method or the PAL method based on the data method information (step S22). When the data system is the NTSC system, the image processing unit 200 converts the image data to the PAL system (step S24), and transmits the image data to the portable device 10 (step S30). When the data method is the PAL method in step S22, the image processing unit 200 does not convert the image data (step S26) and transmits it to the portable device 10 in the PAL method (step S30).

  If the display of the portable device 10 is possible in either the NTSC system or the PAL system in step S14, the image processing unit 200 does not convert the image data (step S28) and transmits it to the portable device 10 in the NTSC system or the PAL system ( Step S30).

  According to the first embodiment, the image processing unit 200 changes the image method of image data to the portable device 10 when the data method and the display method are different (in the case of the PAL method in Step S16 and in the NTSC method in Step S22). Is converted to a display method that can be displayed (step S18 or step S24), and the image data is transmitted to the portable device 10 (step S30). On the other hand, when the data method and the display method are the same image method (in the case of the NTSC method in step S16 and the PAL method in step S22), the image data is not converted (step S18 or step S26), and the image data is transferred to the portable device 10. (Step S30). Thereby, the portable device 10 can display an image regardless of whether the display method of the portable device 10 is the NTSC method or the PAL method. Therefore, the portable device 10 can be attached to the in-vehicle device 100 regardless of the display method.

  When the portable device 10 can display regardless of the image format (when the NTSC format or the PAL format is possible in step S14), the image processing unit 200 does not convert the image data (step S28), and the image data Is transmitted to the portable device 10. As described above, when the portable device 10 can display both the NTSC system and the PAL system, the image processing unit 200 does not convert the image system of the image data and can perform no extra processing.

  In the first embodiment, the NTSC system or the PAL system has been described as an example of the image system. The image system may be a SECAM (Sequential Courier A Memory) system in addition to the NTSC system and the PAL system. Further, for example, an analog system and a digital system, or a standard television system and a high-definition television system may be used.

  In the first embodiment, the portable portable navigation device (portable navigation device) has been described as the display portable device. The display portable device may be any portable device that displays an image. Further, the data output from the DVD / CV playback unit 135 as image data has been described as an example. The image data may be data output from a tuner, a video tape recorder, a storage card, or the like.

  Furthermore, in the first embodiment, the example in which the image processing unit 200, the data method detection unit 202, and the display method detection unit 204 are provided in the in-vehicle device 100 has been described. In the case of this configuration, the portable device 10 may convert the image data based on the data method of the image data input via the connectors 150 and 30 and the display method of the portable device 10. In the first embodiment, the in-vehicle device is described as an example of the electronic device, but the present invention is not limited to this.

  The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims.・ Change is possible.
