The same applies when an input operation is performed using an input interface such as another mouse or remote controller.

  Next, details of the display operation of the icon acquired from the information terminal in the present embodiment will be described. FIG. 7 shows a main flow of the icon display operation. First, when a terminal mode connection is established, icon image data from the information terminal 110 is acquired in the electronic device 130 (S201). Next, the file format determination unit 310 determines whether or not the icon image data can be transparently processed. Here, it is determined that transparency processing can be performed when the icon image data file is in PNG (Portable Network Graphics) format, and transparency processing is performed when the file format is any other file format, bitmap format, or JPEG format. It is determined that it cannot be performed (S202). The file extension is used to identify the file format.

  When the icon image data is in the PNG format, that is, when it is determined that the transparency processing can be performed, the transparency processing unit 340 displays the background of the icon 10 as shown in FIG. Transparent processing is performed so that the portion 14 matches the background color of the screen (S203). Next, the icon size adjustment unit 330 determines the display size of the icon 10 from the data size of the icon image data, and compares the display size of the icon on the electronic device side with respect to whether or not the display size should be changed. Is determined (S204). However, the determination of such a change in display size is not necessarily an essential step. If it is determined that the display size needs to be changed, the icon size adjustment unit 330 changes the icon display size (S205), and the icon is displayed on the screen (S206).

  On the other hand, when the image data of the icon is other than the PNG format, that is, when it is determined that the transparency process cannot be performed, the pedestal generating unit 320 prepares a pedestal for displaying the icon (S207), Next, the icon size adjustment unit 330 determines whether or not to change the icon display size (S208). As will be described later, the icon size adjustment unit 330 adjusts or changes the icon display size so that a border or a frame is formed on the pedestal when the icons are combined on the pedestal (S209). Next, the pedestal composition unit 340 synthesizes the icon image data and the pedestal image data (S210), and the display control unit 220 displays the icon synthesized on the pedestal on the screen (S211).

  Next, details of the pedestal generating unit 320 will be described. As shown in FIG. 8A, the pedestal generating unit 320 generates a pedestal 400 that is rectangular two-dimensional image data. The image data of the pedestal 400 may be generated at a timing when it is determined that the transparency process cannot be performed, or the pedestal image data may be stored in a memory or the like in advance and the transparency process may be performed. The image data may be read from the memory when it is determined that it cannot be performed.

  Preferably, the base 400 has a display size of vertical H × width W, and the display size of the base 400 is preferably somewhat larger than the display size of the icon on the electronic device side, in other words, such an icon. Is set to such a size that an edge of the pedestal is formed. Alternatively, the display size of the pedestal may be approximately the same as the display size of the icon of the electronic device. When the icon on the electronic device side is rectangular, the display size of the pedestal 400 is set to be similar to such an icon. For example, the aspect ratio of the icon on the electronic device side and the aspect ratio (W: H) of the pedestal 400 are made equal.

  The color of the pedestal 400 is set to a color having a contrast with the background color of the screen of the electronic device 130. The color of the pedestal 400 may be fixed in advance or may be variable. For example, when a table in which the relationship between the background color of the screen and the color of the pedestal 400 is defined in advance is stored in a memory or the like, and the pedestal 400 is generated, the table corresponding to the background color of the screen is referred to 400 colors can be selected. Furthermore, when the color information of the background part unrelated to the design can be detected from the icon image data, the color of the pedestal 400 can be set to a color that causes contrast with the background part. Also in this case, it is possible to select a desired color of the pedestal 400 by previously defining a color relationship in which contrast is generated in a table and referring to the table.

  The icon size adjustment unit 330 determines the display size (vertical H1 × width W1) of the icon from the data size of the image data of the icon 10 as shown in FIG. However, when the display size information of the icon can be acquired from the information terminal 110, the display size (vertical H1 × width W1) is determined from the size information. The icon size adjustment unit 330 compares the display size (H × W) of the pedestal 400 generated by the pedestal generation unit 320 with the display size of the icon 10 (H1 × W1), and changes the display size of the icon 10. It is determined whether or not. As shown in FIG. 8C, this determination criterion is whether or not a border 410 having a certain size is formed around the icon 10 when the icon 10 is combined on the pedestal 400. The border 410 is expressed by ΔH = (H−H1) / 2 and ΔW = (W−W1) / 2, and the icon size adjusting unit 330 has a relationship of h1 ≦ ΔH ≦ h2 and w1 ≦ ΔW ≦ w2, for example. If satisfied, it is determined that it is not necessary to change the display size of the icon 10, and if it is outside this range, it is determined that the display size of the icon 10 needs to be changed, and the icon 10 is within the range. Change the display size of. The display size can be changed using a known means such as thinning out data or interpolating data.

  As shown in FIG. 8C, the image composition unit 340 composes the icon 10 on the pedestal 400 and provides it to the display control unit 220. As a result, the icon 10 is displayed on the screen via the pedestal 400. FIG. 9A shows an example in which the icon 10 that cannot be transparently processed is displayed via the pedestal 400. The icon 10 is surrounded by a frame-shaped border 410, which is somewhat larger than the other icons 22 to 32 or similar in size, and has a contrast with the background color of the display screen 20. Displayed. For this reason, compared with the conventional icon display shown in FIG. 1B, the uncomfortable feeling with the other icons 22 to 32 is reduced, the unity with those icons is increased, and the appearance or design of the icon 10 itself is improved. Will also improve.

  Next, a second embodiment of the present invention will be described. In the above embodiment, when the icon acquired from the information terminal 110 cannot be transparently processed, such an icon is displayed via the pedestal. In the second embodiment, FIG. 9B is displayed. As shown in FIG. 5, the icons 22 to 32 on the electronic device side may be displayed via the pedestal 400 in the same manner as the icon 10. By doing so, a sense of unity between the icons 22 to 32 on the electronic device side and the icon 10 acquired from the information terminal is further improved.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the present invention described in the claims. Deformation / change is possible.
