Description

  The present invention is displayed on the front in information devices such as personal computers, workstations, and mobile phones equipped with a multi-window system capable of displaying a plurality of windows on a display device typified by a liquid crystal or a CRT. The present invention relates to a window transparent display technique in which a window designated in advance can be seen through from a window displayed in front when the background of the window is changed to a transparent display state or a semi-transparent display state.

  Conventionally, in information devices such as personal computers, workstations, and mobile phones, when it is desired to simultaneously display a plurality of screens on a display device such as a liquid crystal or a CRT, the screens are displayed in rectangular areas called a plurality of windows. As an example of such a multi-window system, there is a Windows (registered trademark) of Microsoft Corporation or an X window system which is famous for operating mainly on a UNIX (registered trademark) OS.

  When operating an information device equipped with such a multi-window system, a user can freely operate the display device by performing window operations (display, move, delete, resize, etc.) using an input means such as a mouse or a keyboard. You can select the window to be displayed.

  However, when multiple windows are displayed at the same time, the area where each window overlaps increases, so that information about the window that the user really wants to display is not displayed. It may become.

In the case of displaying such multiple windows at the same time, the front window overlaps the back window and the display of the back window is hidden. Some display information in a transparent state or a semi-transparent state so that window information hidden behind the screen is also visible. (For example, refer to Patent Document 1).
JP-A-6-301505

  However, for example, in an information device having a relatively small screen such as a mobile phone, when displaying a plurality of windows, the windows may be displayed so that the front window covers the entire rear window. However, in such an information device, the user is in a state of being newly visible to the user through the front window until the front window is transparently displayed (hereinafter referred to as “visible state”). I can't know.

  Therefore, when a plurality of (three or more) windows overlap each other and the front window is made transparent, an undesired window may be displayed. Therefore, when the rear window information that has become newly visible is undesired information, the user makes the window in which the desired information is displayed visible through the transparent front window. A window operation using an input means such as a mouse or a keyboard is required. However, in an information device such as a mobile phone with a narrow screen and limited input means, when a plurality of windows overlap each other, there arises a problem that it is difficult for the user to operate the window.

  The present invention solves the above-described conventional problem. When the transparency of a display object that is a window or a drawing object in the window is changed, a display object that is newly visible through the display object is Complex display objects by changing the transparency of other display objects, changing the overlapping state with other display objects, or moving the display position so that a specific display object is set An object of the present invention is to provide an object transparent display device that can display a desired screen state without requiring an operation.

  In order to solve the above-described conventional problems, an object transparent display device of the present invention includes a display device, a display object that is displayed on the display device and is a drawing object inside the window, and display information of the display object. A display object information management unit that manages display object information, and a display object that is displayed on the display device as a visible state, detects a transparency change request of the display object, and displays a preset display through the transparent display object. A display object information update instruction unit that updates display object information so that an object is visible on the display device, and a display update that instructs the display device to update the display object when the display object information is updated. An instruction unit is provided.

  With this configuration, it is possible to display a desired display object through a display object whose transparency has been changed without being obstructed by a plurality of display objects overlapping with a preset display object.

  According to the object transparent display device of the present invention, when the transparency of a display object is changed, a desired display object can be made visible through the display object whose transparency has been changed.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment)
FIG. 1 is a block diagram showing an example of the configuration of an object transparent display device according to an embodiment of the present invention.

  In FIG. 1, a display device 101 is a liquid crystal or a CRT. Based on the display object information held by the display object information management unit 103, the display update instruction unit 102 instructs the display device 101 to display a display object that is a window or a drawing object inside the window.

  FIG. 2 shows an example in which display windows or display objects are displayed on the display device 101 in an overlapping manner. The x coordinate and y coordinate in FIG. 2 are used to represent the display position of the display object. In the display screen 201 of the display device 101 in FIG. 2, a display window 2000 having a display object 20001 is displayed behind a display window 1000 having a display object 10001 and a display object 10002, and the display object 30001 is behind the display window. The display window 3000 is displayed.

  The display object information in FIG. 3 includes a display object ID that identifies each display object, a display window ID that indicates in which window the display object exists, an X coordinate value that defines the display position and display area of the display object, Y The coordinate value, width, height, transparency when displaying the object, visibility indicating whether the display object is actually visible on the display device 101, and transparency of the display object in the visible state were changed. In this case, there are a setting state indicating whether or not the display object is set to be visible through a transparent display object, an overlapping order between the display objects, and the like.

  Here, when “Transparency” is “0”, it is non-transparent, when “1” is transparent, when “Visible” is “0”, it is visible, and when “1” is visible, it is not visible. Suppose there is nothing. Further, when “setting” is “0”, when the transparency of the visible display object is changed, an object that is not set in advance to be visible through the transparent display object, and when “1”, When the transparency of the visible display object is changed, the object is set in advance to be visible through the transparent display object, and the “overlapping order” is “1”, “2”, It is assumed that the number “3”.

  Here, the display window that is currently visible is the display window A, or the display object is the display object A. If the transparency of the display object that is visible is changed, the display window that is preset to be visible is displayed. Hereinafter, the display window B or the display object is referred to as a display object B.

  The display update instruction unit 102 detects that the display object information managed by the display object information management unit 103 has been updated, and instructs the display device 101 to update the display object.

  The display object information management unit 103 holds the display object displayed on the display device 101 and the display object information of the display window. Further, the display object information update instruction unit 104 updates the display object information. Next, the display update instruction unit 102 detects the update of the display object information.

  The display object information update instruction unit 104 receives a transparency change request for the display object A in the visible state from the display objects managed by the display object information management unit 103. Next, when the display object information update instruction unit 104 changes the transparency of the display object A, the display object B set in advance through the display object A (“display object information managed by the display object information management unit 103” The display object information of the display object information management unit 103 is updated so that the “setting” item is “1”) visible to the display device 101.

  More specifically, whether or not there is a display object “1”, that is, display object B, among the “setting” items of the display object information managed by the display object information management unit 103. Determine whether. When it is determined that there is a display object b, when it is determined that there is no display object B, the visibility determination unit 105 determines the transparency of the display object A managed by the display object information management unit 103. change.

  When it is determined that there is a display object B, the overlap determination unit 106 determines whether there is a display object between the display object A and the display object B. When it is determined that there is an overlap, the overlap determination unit 106 updates the display object information of the display object information management unit 103 so that the display object B becomes visible. When it is determined that there is no overlap, the overlap determination unit 106 changes the transparency of the display object A managed by the display object information management unit 103.

  The display object information update instruction unit 104 can also instruct the display information update instruction unit 102 to update the display on the display device 101 without updating the display object information.

  Further, although the transparency of the display object A is changed, the transparency of the display window A that is in a visible state may be changed. Similarly, the display object B that is set in advance may be used as the display window B.

  FIG. 4 is a flowchart showing an example of the operation of the object transparent display device according to the embodiment of the present invention. The operation of each functional block of the object transparent display device according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

  In step S <b> 401, the display object information update instruction unit 104 detects a transparency change request for the display object A in a visible state from among the display objects managed by the display object information management unit 103. Here, it is assumed that the “transparency change request” includes the display object A to be transparent and the transparency.

  In step S <b> 402, the display object information update instruction unit 104 overlaps display objects other than the display object A on the display object B set in advance from a plurality of display object information managed by the display object information management unit 103. Determine whether or not.

  Here, whether or not a plurality of display objects overlap each other can be determined by the “overlapping order” of the display object information (FIG. 3). Further, which display object is the display object B can be determined by the display object information setting state (for example, the item “setting” in FIG. 3 is “1”).

  Step S403 is a process executed when it is determined in step S402 that a display object other than the display object A does not overlap the display object B. In step S401, the display object information update instruction unit 104 performs the process. Based on the detected display object transparency change request, the display object information update instruction unit 104 changes the transparency of the display object A managed by the display object information management unit 103.

  Here, the description is based on the assumption that there is a display object B. However, if there is no display object (the display object B is not set, the display object B is not displayed, etc.), the display immediately below is displayed. The object may be made visible or the transparency of the display object A may not be changed.

  Step S404 is a process executed when it is determined in step S402 that a display object other than the display object A is superimposed on the display object B. The display object information update instruction unit 104 displays the display object B. The display object information is updated so that the transparency of the display object determined to overlap the display object is transparent or semi-transparent. Note that the transparency of the display object A is the transparency notified by the transparency change request in step S401.

  Step S405 is processing executed after step S403 or step S404. In the display object information management unit 103, the display update instruction unit 102 detects that the display object information update has been executed, and the display object information management unit Based on the display object information 103, the display apparatus 101 is instructed to display the display object B in a visible state.

  The configuration and processing contents have been described above as an example of the object transparent display device according to the present embodiment. Here, we explained only the case of setting the transparency for the display object or setting it to be visible in advance when changing the transparency. However, you can set the transparency for the display window, It may be set in advance to be visible when changing.

  Next, the flowchart processing of FIG. 4 will be described using the specific example of FIG. In the following, in the drawings used for the description, the description of the reference numerals already described is omitted.

  FIG. 5 is a specific example when the object transparent display device according to the embodiment of the present invention is applied to a mobile phone. Note that the present invention can be applied not only to mobile phones but also to portable information terminals and digital cameras.

  In FIG. 5, reference numerals 501 to 504 denote display objects before starting the flowchart processing of FIG. 4, and reference numeral 501 corresponds to the display object A described above, and as an example, a screen of a mail application of a mobile phone. Hereinafter, it is referred to as display object A (501). Reference numeral 504 corresponds to a display object B set in advance, and here, as an example, is a screen of a television application in the weather forecast. Hereinafter, it is referred to as display object B (504).

  Also, display objects 502 and 503 indicate two display objects that are superimposed on the display object B (504). Further, it is assumed that only the display object A (501) is visible on the display device (for example, a liquid crystal screen) of the mobile phone. That is, if the display object A (501) is in a non-transparent state, the display objects 502, 503, and 504 are hidden by the display object A (501) and cannot be viewed by the user of the mobile phone.

  Under such conditions, when the display object information update instruction unit 103 detects a transparency change request for the display object A (501) according to step S401 described above, in step S402, the display object information update instruction unit 104 With reference to the display object information of the display object information management unit 103, it is determined that a display object other than the display object A (display object 502, display object 503) overlaps with a preset display object B (504). .

  In step S403, the display object information update instruction unit 104 sets the transparency of the display objects 502 and 503 overlapping the display object B (504) to the completely transparent state, and the display object A (501) transparency is set. Instructs the display object information management unit 103 to update the display object information so as to achieve the transparency according to the transparency change request in step S401. Then, the process of step S405 mentioned above is performed, and the transparent display screen (505) of FIG. 4 is displayed.

  The transparent display screen (505) is displayed on the display objects 506 to 508 after changing the transparency (transparent display objects in which the respective transparency of the display objects 501 to 503 are changed) and the display object B (through the flowchart of FIG. 4). 504) are overlapped and displayed on the display device 101. FIG. Hereinafter, the display object 506 corresponding to the display object A (501) after changing the transparency is referred to as a transparent display object A (506).

  From the display result of the transparent display screen (505), the user of the mobile phone simultaneously sees the display object B (504) that is a preset TV application screen through the transparent display object A (506) that is the mail application screen. Can do.

  In this embodiment, in step S404, the transparency of the display object overlapping the display object B set in advance is changed, but the transparency of the area overlapping the display area of the display object B is partially changed. May be. Thereby, the display area of the display object B can be made visible through the display object A without excess or deficiency.

  In step S404, the transparency of only the region overlapping the display object A that overlaps the display object B may be partially changed. As a result, the display object B is displayed only through the display area of the display object A that was originally requested to change the transparency, so that other display objects that are visible and overlap the display object B are unexpectedly transparent. Can be prevented from being changed.

  In this embodiment, in step S404, the transparency of the display object A may be changed after changing the overlapping order between the display objects so that the display object B overlaps immediately below the display object A. . Thereby, the overlapping of the display objects 501 to 504 in FIG. 5 is changed to the overlapping order of the display objects shown in FIG. That is, the overlapping order is changed so that the display object B (601) becomes a display object immediately below the display object A (506). Thus, together with the change in the transparency of the display object A, the transmissive display screen (505) is finally displayed on the display device 101 as a visible state.

  Further, as a present embodiment, in step S404, for a display object that overlaps both display object A and display object B, the display object A may be changed in transparency after the display is finished. Good. As a result, the overlapping of the display objects 501 to 504 in FIG. 5 is only the overlapping of the transparent display object A (506) and the object B (602), as shown in FIG. 6B. Therefore, finally, the transparent display screen (505) is displayed on the display device 101 as a visible state.

  In the process of step S404 described above, when the overlapping area of the display areas of the display object B and the display object A is equal to or smaller than the predetermined area S, the display position of the display object B is increased so as to widen the overlapping area. The display object B may be displayed through the display object A according to the transparency, the overlapping order, the display state, or the combination of the display objects overlapping the display object B.

  As a result, as shown in the upper diagram of FIG. 7, the overlapping portion of the display areas of the display object A (501) and the display object B (504) (the hatched portion indicated by 701 in FIG. 7, S1 is its area) Is extremely narrow, that is, even if the area S1 (701) <the preset area S (S ≧ 0), the display position of the display object B (504) is moved as shown in the lower right diagram of FIG. Then, after changing the overlapping order of the display objects 502 to 503, the transparent display screen (505) in which the display object B (503) is visible is displayed on the display device 101 through the transparent display object A (506). it can.

  Note that the behavior of the display object information change instruction unit 104 in step S404 described above is that the user's desired format is displayed through the display object A when another display object overlaps the preset display object B. In order to make the display object B visible to the display device 101, the processes of the respective steps S404 described above may be combined.

  In the present embodiment, each functional block constituting the object transparent display device is typically realized as a program that operates on a CPU, a memory, or a required information device. All may be realized as an LSI which is an integrated circuit. These LSIs may be individually made into one chip, or may be made into one chip so as to include a part or all of them. The name used here is LSI, but it may also be called IC, system LSI, super LSI, or ultra LSI depending on the degree of integration.

  Further, the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible. An FPGA (FIELD PROGRAMMABLE GATE ARRAY) that can be programmed after manufacturing the LSI or a reconfigurable processor that can reconfigure the connection and setting of circuit cells inside the LSI may be used.

  Further, if integrated circuit technology comes out to replace LSI's as a result of the advancement of semiconductor technology or a derivative other technology, it is naturally also possible to carry out function block integration using this technology. Biotechnology can be applied.

  As described above, according to the object transparent display device of the present invention, when the transparency of the display object is changed, the user does not need a complicated display object operation, and the user desires through the display object whose transparency is changed. The display object to be made can be made visible.

  The object transparent display device according to the present invention has an effect that a preset window is displayed through a transparent or semi-transparent window in a multi-window system in which windows are overlapped and covered. It is useful in a device or system that has a narrow screen such as a mobile phone or a portable information terminal and whose display object often hides another display object. It can also be applied to applications such as digital cameras and in-vehicle devices.
