It is a figure which shows a prior art example. It is a figure which shows another prior art example. It is a figure which shows another prior art example.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram of a divided screen display method and apparatus according to the present invention, and shows a functional block diagram in which the present invention can be implemented in various modes. In addition, in the same figure, the function part which performs each function can be said to be a means which performs each function.

  In the illustrated embodiment, an example in which a mobile device connection device such as a navigation device or a personal computer and a mobile device 10 such as a mobile phone, a smartphone, a PDF, or a mobile personal computer are connected by the connection unit 2 is shown. The connection unit 2 can be connected wirelessly such as wired or Bluetooth.

  The image capture unit 3 captures an image from the portable device connected by the connection unit 2 and displays it on the screen by the image matching unit 8 described later. The screen division display detection unit 5 detects a state in which the screen is divided and displayed. Thereby, for example, in FIG. 3A, various divided screens are detected.

  The split screen aspect ratio detection unit 4 detects the ratio of length to width in each split screen, and X / Y = 1.35 is the portion for capturing audio information, and the length (Y) is longer. I understand. In addition, although the part which takes in camera information is X / Y = 0.658 and the width is long and the fuel consumption information is X / Y = 0.699 and the width is long, the part combining the camera information and the fuel consumption information is X / Y It can be seen that Y = 1.20 and the longitudinal direction (Y) is long.

  The portrait image converter 6 performs a function of converting a landscape image sent in the normal terminal mode into a portrait screen. As a result, when the split screen is a portrait screen, when a landscape screen is sent in the terminal mode, it can be made a portrait screen and can be matched to the portrait screen. The image is sent to the image matching unit 8 and matched according to the size of the divided screen. This image can be used effectively for explanations.

  The portrait / landscape screen request unit 7 requests the mobile device 10 for either the landscape display 11 or the portrait display 12 via the connection unit 2, and the mobile device 10 outputs an image in accordance with the request. To do. In this case, the divided image aspect ratio detection unit 4 determines that the length is long when the aspect ratio is greater than 1, and requests a vertically long image. On the other hand, when it is 1 or less, it is detected that the length and width are the same or the width is long, and when the length is long, the image of the portrait display 12 is requested, and when the length is long, the image of the landscape display 11 is requested.

  In general, when a portable device such as a smartphone is used by connecting it to another device such as a navigation device, a horizontally long screen is output as a terminal mode. Therefore, on a screen with the same length and width as described above, or a landscape screen, the smartphone outputs a landscape screen in the normal mode, whereas on a portrait screen, the screen is forced to change from a regular landscape screen to a portrait screen. The operation to change to will be performed. In response to the request, the image capturing unit 3 captures the image of the landscape display 11 or the image of the portrait display 12 and outputs it to the image matching unit 8.

  In the image matching unit 8, matching is performed so that, even if the sizes of the horizontally long screen and the vertically long screen are different, the furniture is included. Thereby, all the images can be fitted into all the divided screens, but depending on the shape, there may be a remainder in the horizontal direction or the vertical direction, and the portion is blank. In this way, the display unit 9 can fit the image of the portable device 10 in the divided image.

  The mobile device 10 includes an attitude sensor 13 that detects whether the mobile device body is currently in portrait orientation or landscape orientation. The current landscape orientation screen outputs a landscape display 11 screen as an image, and the portrait orientation screen is displayed. Then, the screen of the portrait display 12 is output as the image. Accordingly, when a portrait screen is requested by the portrait / landscape screen request unit 7, a portrait display 12 screen can be output, and when a landscape screen is requested, the landscape display 11 screen can be output immediately.

  In the present invention comprising the functional block diagram as described above, the present invention can be implemented by operating according to an operation flow as shown in FIG. 2, for example. In the example of the split screen display process of the mobile device shown in FIG. 2, it is determined whether or not the mobile device is initially connected. This is performed by detecting whether or not the mobile device 10 such as a mobile phone or a smartphone and the mobile device connection device 1 such as a navigation device are connected by the connection unit 2 in FIG.

  When the mobile device 10 is not yet connected, this operation is repeated to stand by. When the mobile device 10 is connected, the process proceeds to step S2 to determine whether the screen is divided. If it is determined that the screen is not divided, the process proceeds to step S9 to request a landscape display screen and display a landscape display image on the screen (step S10). Since this is a normal terminal mode and the screen of a general device is horizontally long, the horizontally long screen is sent to the mobile device connecting apparatus side accordingly, and this is displayed.

  On the other hand, when it is determined that the image is divided, the aspect ratio (X / Y) of the portable device image display area is detected (step S3). Thereafter, it is determined whether or not the aspect ratio (X / Y) is greater than 1 (step S4). When it is determined that it is greater than 1, that is, when it is determined that the height is large, it is determined whether or not to convert the image ( Step S5). For example, a screen such as a simple explanation as shown in FIG. 7 can be solved only by making the horizontal direction vertical, so the horizontal screen is converted into a vertical screen (step S8). On the other hand, when an explanatory text is placed at a specific position in the navigation drawing as shown in FIG. 10, the explanatory text may disappear, so the horizontal screen is not converted into the vertical screen. At that time, the process proceeds to step S6, and the portable device is requested to output a vertically long display screen.

  On the other hand, when the aspect ratio (X / Y) is determined to be other than that, that is, when the aspect ratio is the same or smaller, a horizontally long image is requested (step S7), and the horizontally long image is displayed on the screen. (Step S8). This can also be done in terminal mode. Thereafter, the process proceeds to step S9, matching processing is performed (step S9), and all the processes are completed.

  With the above processing, in an apparatus comprising a large number of divided screens as shown in FIG. 3A, the aspect ratio (X / Y) of each divided screen is obtained as shown in FIG. As a result, when putting the screen of the portable device in the audio information part, a portrait display screen is requested and the matching process is performed. As a result, the portrait screen is inserted with a little blank at the right end.

  Also, when fitting into the camera information part, X / Y = 0.658 is obtained, and it can be seen that the part is a horizontally long screen. Therefore, by requesting a horizontally long screen and matching it, Although a part of the space is created underneath, a horizontal screen is formed in which the entire space can enter.

  On the other hand, when the screen of the portable device is pasted on both the camera information and fuel consumption information divided screen portions, the aspect ratio of this portion is X / Y = 1.20, and a vertically long screen is required. As a result, as shown in FIG. 5 (a), although a little space is left on the left side, a screen as shown in FIG. 5 can be displayed. Similarly, the altitude information portion is extremely horizontally long as X / Y = 0.392, and as a result of requiring a horizontally long screen, a large space is opened on the lateral side.

  FIG. 6 shows an example in which the screen of the portable device is pasted on both the camera information and the fuel consumption information, and this portion is a vertically long screen with X / Y = 1.20 as described above. Further, since it is an explanatory text, it is only necessary to convert a horizontal image into a vertical image, but an example in which a vertically long image is requested is shown and an example in which a vertically long screen is pasted is shown. However, unlike the case of FIG. 5A, the image matching processing is displayed on the entire screen so as not to generate a blank. However, although only a part of the portable device is displayed, the next page can be viewed by scrolling the screen as shown in FIG.

  On the other hand, FIG. 7 shows an example in which all the vertically long images of the mobile device are displayed. On this screen, however, a space is formed on the left side for convenience of matching. Further, as shown in FIG. 5B, more information can be flowed on a small screen. However, the image becomes smaller and difficult to see. As shown in FIGS. 6 and 7, the screen can be displayed in various modes by the matching process.
