In this case, an arbitrary part is cut out, and the resolution is further adjusted to be used as wallpaper for a mobile phone as shown in FIG. In addition, a function has been developed in which an original image of such a wallpaper is taken in, a main part is discriminated and cut into a predetermined shape to obtain a wallpaper.

  Mobile phones in recent years have become multi-functional as described above and have functions as audio devices, and various types of information fetch operations are frequently performed through Internet connection. On the other hand, there is a monitor screen of the navigation device in the vehicle on which the user is boarded, so that various operations of the navigation device and various in-vehicle devices such as the audio and air conditioner of the vehicle can be comprehensively performed. When selected, various selection operations are displayed on the screen of the monitor, but the wallpaper as the background is often set to select an arbitrary image from images provided by the manufacturer in advance. .

  For this reason, the wallpaper of the monitor mounted on the vehicle is, for example, the wallpaper of the mobile phone as shown in FIG. 3B, which is based on the image of FIG. In the case of the image as shown in FIG. 6C, the images of both images are greatly different from each other, so that the user may feel uncomfortable and may feel a device that is difficult to handle.

  This is not limited to the relationship between the mobile phone and the vehicle-mounted monitor as described above. For example, a personal computer, a mobile phone, a personal digital assistant (PDA), a portable audio player, or a portable TV / video player, an in-vehicle head unit. This also occurs in the same manner.

  Therefore, the present invention provides an in-vehicle monitor that is used for performing various operations when driving a vehicle, for example, wallpaper that a user of a device that is used on a daily basis is a favorite without requiring any special operation by the user. It can be automatically transferred to the screen of various devices, etc., and the favorite wallpaper can be automatically displayed on the in-vehicle monitor, etc., thereby making it a device that feels familiar and using various functions. The main object is to provide a wallpaper display device that can be an easy-to-use device.

  In order to solve the above problems, the wallpaper display device according to the present invention is configured to connect the external device connection unit connected to an external device having wallpaper data so that data communication is possible, and the wallpaper data of the external device captured by the external device connection unit. A wallpaper size adjusting unit that adjusts the size of the wallpaper so as to be adapted to the image display unit, and an image output unit that outputs the image adjusted by the wallpaper size adjusting unit to the image display unit.

  Further, another wallpaper display device according to the present invention includes a wallpaper data recording unit that records wallpaper data of an external device captured by the external device connection unit in the wallpaper display device, and a device connected to the external device connection unit When the wallpaper data already exists in the wallpaper data recording unit, the wallpaper data recorded in the wallpaper data recording unit is used for display.

  Another wallpaper display device according to the present invention is characterized in that the wallpaper display device is used in an in-vehicle device.

  Another wallpaper display device according to the present invention is characterized in that, in the wallpaper display device, the external device is any one of a mobile phone, a portable player, a portable information terminal, and a personal computer.

  Since the present invention is configured as described above, the wallpaper that the user of the device that is used on a daily basis is favorite is automatically used when using another device without any special operation by the user. These devices can be taken in and used, and these devices can be devices that can feel familiarity as well as devices that are used everyday.

  The present invention has the purpose of automatically capturing and using the wallpaper of the device as a user's favorite wallpaper for the purpose of automatically connecting the external device having the wallpaper data so that data communication is possible, and the external device. The wallpaper size adjustment unit that adjusts the wallpaper size to match the image display unit with the wallpaper data of the external device captured by the connection unit, and the image output that outputs the image adjusted by the wallpaper size adjustment unit to the image display unit It was realized by having a part.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows that a wallpaper display device according to the present invention is used for a function part for displaying an in-vehicle monitor 2 such as a navigation device of an in-vehicle device 1, and a mobile phone 21 as a mobile device 20 is communicably connected to the in-vehicle device 1. At the time, the function part which takes in and displays the wallpaper data of the mobile phone 21 in the in-vehicle device 1 is mainly shown. In addition to the vehicle-mounted monitor 2 as described above, the vehicle-mounted device 1 shows an example that can be used in the same manner when wallpaper is used for the operation function display section of the head unit 3.

  When the mobile phone 21 is brought into the vehicle of FIG. 1 and can be wirelessly communicated by, for example, Bluetooth or wireless LAN, or connected by a function of performing wired communication, the in-vehicle device 1 is connected to an external device. Data can be exchanged in the section 4. The data capturing unit 5 captures wallpaper data used by the mobile phone 21, particularly in the wallpaper data capturing unit 6. At this time, it is assumed that the mobile phone 21 has a function of outputting wallpaper data to the outside as its own function, and output is permitted. In addition, when the wallpaper data at that time is used in the memory, especially when the favorite wallpaper is taken from a photograph or the like, if the original image data of the photograph exists in the memory, the original image data is captured as much as possible. Thereby, even a wallpaper having a relatively small screen and a specially shaped screen like the mobile phone 21 can be easily used for the monitor 2 of the in-vehicle device 1, for example. However, this is not particularly necessary when the wallpaper is just a color or pattern.

  The above-described wallpaper data captured by the wallpaper data capturing unit 6 is stored in the image display processing unit 7 for displaying various images on the in-vehicle monitor 2, particularly in the wallpaper display processing unit 8 for performing wallpaper display processing. Input to the wallpaper size adjustment unit 9. In the wallpaper size adjusting unit 9, the display range setting unit 10 cuts out a predetermined range from the wallpaper data.

  In that case, for example, the range of the main part of the image is selected from the original image data of the wallpaper made up of the photograph taken by the user as shown in FIG. When a wallpaper having a predetermined resolution is displayed with a size as shown in FIG. 5A, the range of the same shape as that shown in FIG. The display range setting unit 11 performs processing for setting the shape range. Further, the resolution adjustment unit 10 forms a wallpaper having a predetermined resolution with the size of the in-vehicle monitor as shown in FIG. 3C for the image data in the shape range of FIG. Note that FIG. 3B shows a comparative example in which the in-vehicle monitor displays a wallpaper provided in advance when the present invention as described above is not used.

  When a predetermined wallpaper is created by the wallpaper size adjustment unit 9 in this way, the wallpaper display processing unit 8, which is a function unit of the image display processing unit 7, outputs wallpaper display data via the image output unit 13. The wallpaper is displayed on the in-vehicle monitor 2. Such a wallpaper display function can also be used as wallpaper for the display unit when the operation function display unit is present in the head unit 3 of the in-vehicle device.

  In the example shown in FIG. 1, when the in-vehicle device 1 is provided with a data recording medium 15 such as a memory and the data fetched by the data fetching unit 5 can be recorded, the wallpaper data fetching unit 6 When the wallpaper data is taken in as described above, it can be recorded in the wallpaper data recording unit 16 of the data recording medium 15. In that case, when the wallpaper selection unit 12 of the wallpaper display processing unit 8 selects and displays an arbitrary wallpaper, data is read from the wallpaper data recording unit 16 by the data reading unit 17 and used. In this example, an arbitrary wallpaper is selected according to a user's instruction and the like, and the above-described processing in the wallpaper size adjusting unit 9 is performed, and then the display on the in-vehicle monitor 2 can be performed.

  By using the wallpaper data recording unit 16 for storing such wallpaper data, when the connection of the mobile phone 21 is detected by the external device connection unit 4, the ID number of the connected device is output to the image display processing unit 7. Then, the image display processing unit 7 detects whether the wallpaper of the connected device has already been stored from the wallpaper selection unit 12 through the data reading unit 17, and if it already exists, reads it immediately and performs wallpaper display processing. To enable output. At that time, if the wallpaper size adjusted data itself is recorded in the wallpaper data recording unit 16, it can be directly output to the image output unit 13, and the repeated capture and size of the wallpaper data from the mobile phone can be performed. Adjustment is also unnecessary.

  In the example shown in FIG. 1, when the mobile phone 21 is brought in as the mobile device 20, the same wallpaper is displayed on the in-vehicle monitor 2 using the wallpaper data of the mobile phone. Similar processing can be performed when a portable player 22 such as an audio player, a portable TV / video player, or a personal digital assistant (PDA) 23 is brought into the vehicle. Furthermore, portable navigation devices have been used due to recent downsizing of navigation devices. Therefore, when such a portable navigation device is brought into the vehicle and used, when the portable navigation device is directly connected to the personal computer 24 or connected so as to be communicable, the portable type as the in-vehicle monitor 2 is similarly used. It is also possible for the navigation device to capture the wallpaper data of the personal computer 24 and use it as wallpaper as described above.

  FIG. 2 shows an example of an operation flow for implementing the on-vehicle monitor wallpaper display device composed of the functional blocks as described above. In the wallpaper display process of the in-vehicle monitor shown in FIG. 2, it is determined whether or not connection of an external device that can communicate first is detected (step S1). That is, in the example of FIG. 1, when a mobile phone 21 having a function capable of communicating with each other such as Bluetooth is brought into the vehicle, the external device connection unit 4 of the in-vehicle device 1 detects this by communicating with each other, At that time, in step S1, it is determined that the connection of the communicable external device is detected. Here, when it cannot be detected yet, this detection operation is repeated and the system waits.

  When connection of an external device capable of communication is detected in step S1, it is determined whether or not wallpaper data can be captured (step S2). That is, it is determined whether or not the connected communicable device has a function of outputting the wallpaper data stored therein to the outside. If the device does not have the function, the process returns to step S1 and the above operation is repeated. . Further, when it is detected on the in-vehicle device side that the device connected to be communicable as described above has a function of outputting wallpaper data, the wallpaper data currently used by the connected device is captured (step S3). ).

  After that, the captured wallpaper data is stored as one operation (step S16). For example, after changing from the usage state of the captured wallpaper to another wallpaper, whether the same wallpaper exists when capturing the wallpaper of the same device. If it exists, the stored wallpaper can be used immediately. As another operation after step S3, in the example shown in the figure, it is determined whether or not the wallpaper original image data has been taken in (step S4).

  In other words, if the external device that is communicating is a small device with a screen such as a mobile phone, the displayed wallpaper is a small screen and is displayed in a vertically long shape. In many cases, when the wallpaper data is captured, the original wallpaper original image data used as the wallpaper by the external device is captured and used (step S5).

  However, when the original image of the currently used wallpaper does not exist or the output of the original image is prohibited in the external device connected to be communicable, the wallpaper data itself of the connected device is used (step S6). In both cases of step S5 and step S6, the wallpaper data is cut out to the display shape of the monitor thereafter (step S7). That is, when there is a wallpaper original picture as shown in FIG. 3 (f) as described above, the mobile phone cuts out the main video portion in the screen into the shape shown in FIG. 3 (d). In the in-vehicle monitor, as shown in FIG. These operations are performed by the display range setting unit 10 of the wallpaper size adjusting unit in the wallpaper display processing unit 8 of FIG.

  Next, in the illustrated embodiment, it is determined whether or not the resolution of the captured wallpaper is coarser than the resolution of the in-vehicle monitor (step S8). If the resolution of the captured wallpaper is, for example, the wallpaper data currently displayed on the mobile phone is captured and displayed on the in-vehicle monitor, the captured wallpaper resolution is determined to be coarser than the monitor resolution. At that time, the process proceeds to step S10, and correction processing for refining the resolution of the wallpaper data is performed, thereby eliminating the roughness of the edge of the image when displaying a photo with a coarse resolution, and making the wallpaper look good.

  If the resolution of the wallpaper captured in step S8 is not coarser than the resolution of the monitor, that is, if the resolution of the captured wallpaper is the original picture data, the image data is used as it is as the wallpaper of the in-vehicle monitor. Is too large, the resolution is coarsened to an appropriate amount of data and adapted to the size of the monitor (step S9). These resolution adjustments are performed by the resolution adjustment unit 10 of the wallpaper size adjustment unit 9 in the wallpaper display processing unit 8 of FIG.

  After the resolution is adjusted in steps S9 and S10, the wallpaper data is suitable for the vehicle monitor, and the wallpaper data is output to change the wallpaper of the vehicle monitor (step S11). Next, in the illustrated embodiment, it is determined whether or not the process of automatically returning the wallpaper is performed (step S12). That is, after setting the wallpaper of the mobile phone familiar to the user brought into the vehicle as described above as the wallpaper of the in-vehicle monitor, and then using the wallpaper as it is when there is no change instruction from the user, It is determined whether or not there is an instruction to change, and waits in this state until there is an instruction to change wallpaper (step S15). On the other hand, when the setting is made to automatically restore the wallpaper, the process proceeds to step S13 to determine whether or not the communication with the external device has been disconnected.

  If it is determined that the communication has not been disconnected, this state is continued until the communication is disconnected. If it is determined that the communication is disconnected, a change process for returning the wallpaper is performed (step S14). Further, when it is determined in step S12 that the process of automatically returning the wallpaper is not performed, the process proceeds to step S15, the wallpaper change instruction is issued, and the communication with the external device is disconnected in step S13. When it is determined that it has been performed, the process proceeds to step S14 to perform a changing process for returning the wallpaper.

  In the above-described embodiment, an example in which the present invention is applied to the wallpaper display of the monitor of the in-vehicle device is shown. However, when the display unit is present in the head unit 3 of the in-vehicle device as shown in FIG. Is also possible. In addition, as shown in FIG. 1, the device connected to this in-vehicle device can be applied when a portable player 22 other than a cellular phone, a PDA 23 as a portable information terminal, etc. are brought into the vehicle. Is applicable. Further, when the in-vehicle device 1 can be taken outside, for example, as a portable navigation device, the present invention can be applied by communicating with the personal computer 24 or the like at home. Further, in addition to being used for displaying the wallpaper of the in-vehicle device as in the above-described embodiment, the present invention can also be applied to the mutual use of wallpaper between various devices, such as exchange of wallpaper data between the mobile phone 21 and the portable player 22, for example. is there. In that case, the wallpaper display device of the present invention is incorporated as a wallpaper display function of each device.
