Description

  The present invention relates to a display device and a display method for displaying selection items on a display unit using a hierarchical menu.

  In an information device such as a digital television device, when various functions are selected and executed by a user operation, each function is displayed on the screen as a menu item. A desired function is executed by a selection and determination operation using the operation means. As a conventional example of such a menu, a hierarchical menu composed of a plurality of layers is known. In this case, for example, when performing menu display in a state where the items of the first layer are determined, if only the currently selected lower layer (second layer) is displayed, the selection history (first layer) is not displayed. So difficult to use. Therefore, in the technique shown in Patent Document 1, the first hierarchy and the second hierarchy are displayed on the same screen, and when the selection is made on the first hierarchy, the items not selected on the first hierarchy are displayed lightly. At the time of selection, the lower third layer is displayed on another screen.

JP 2003-108280 A

  In the above-described technique, when a menu is selected in the second and subsequent layers, the next layer corresponding to the currently selected item is not known. For this reason, when the item which the user intended in the next hierarchy is not found, it is necessary to perform an operation to display the previous hierarchy again. In the above-described technique, when items in the second hierarchy are selected, the first hierarchy and the second hierarchy are clearly displayed by thinly displaying the items of the first hierarchy that are not selected. However, when selecting an item from the third layer onward, the items of the next layer related to the selected layer and the currently selected item are not displayed, so that the selection process is unknown and the user may be confused.

  Therefore, an object of the present invention is to display a plurality of layers on the same screen and display items by changing the transparency and display color of each layer, thereby providing a display device and a display method excellent in visibility and operability. Is to provide.

In order to solve the above-described problem, a display device according to the present invention includes a display unit that displays a plurality of hierarchical menus configured from a plurality of layers, a selection unit that selects an arbitrary menu item in each hierarchical menu, Control means for setting transparency for each hierarchical menu. The selection means makes a transition from the selected state for the arbitrary menu item to the selected state by performing a predetermined operation in the selected state for the arbitrary menu item, and the display means When an arbitrary first menu item in the first hierarchical menu is being selected by the predetermined operation, a second hierarchical menu corresponding to the arbitrary first menu item being selected is displayed. When the arbitrary first menu item being selected is selected, the control means determines the transparency of the first hierarchical menu to which the selected first menu item has been selected in the selected state. The transparency of the second hierarchical menu corresponding to the selected arbitrary first menu item is set higher than the transparency of the first hierarchical menu, and the transparency of the second hierarchical menu in the selected state is set. Control to set lower than the transmittance is performed.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes easy to judge the item which belongs to a several hierarchy visually instantly, and can improve a user's operativity.

  FIG. 1 is a block diagram showing a configuration example of a broadcast receiving apparatus to which the present invention is applied. Broadcast receiving apparatus 100 receives a broadcast signal at tuner 101. With respect to the received broadcast signal, the signal processing unit 102 performs channel selection, demodulation processing, and the like, and video data, audio data, and the like are separated and extracted. The extracted video data is decoded by the decoding unit 103, supplied to the output unit 104, and displayed on the monitor 200. The audio data is decoded by the decoding unit 103, supplied to the output unit 104, and output by audio output means such as a speaker (not shown). These processes are performed according to a control instruction of the control unit 105 using a CPU (Central Processing Unit) or the like.

  The input unit 108 receives an instruction from a user operation and transmits the instruction to the control unit 105. When a menu display instruction is issued, the control unit 105 acquires display data for menu items stored in the memory 107. The data is processed into a signal suitable for the display form by the display processing unit 106, and after the transparency related to the screen display is changed by the transmission processing unit 109, the data is output to the monitor 200 via the output unit 104. Here, “transparency” represents the degree to which an item or area is displayed through and can be expressed, for example, as a percentage (non-transparent at 0%).

  Next, an initial menu display operation in the broadcast receiving apparatus 100 having a hierarchical display function will be described with reference to FIGS. FIG. 2 is a flowchart showing an operation example of the broadcast receiving apparatus 100 when the user gives a menu display instruction. FIG. 3 shows an example of a display area including a plurality of hierarchies on the display screen, and items 1 to 5 of the second hierarchy related to item 1 are displayed together with items 1 to 5 of the first hierarchy. Show the state.

  First, a menu display instruction is notified to the control unit 105 via the input unit 108 by a user operation using a remote controller or the like (S201). The control unit 105 acquires the menu item data related to the first layer from the menu item display data stored in advance in the memory 107 (S202). The data is sent to the display processing unit 106, converted into an appropriate display form, and output to the monitor 200 via the output unit 104 (S203). The menu items in the first layer are displayed with the transparency defined by the transparency processing unit 109. For example, the menu items 1 to 5 are displayed on the monitor 200 in a non-transparent state.

  The control unit 105 determines from the menu item display data stored in advance in the memory 107 whether or not there is a next layer (second layer) for the first selection item of the first layer (S204). As a result, when the second hierarchy exists for the initial selection item of the first hierarchy, the process proceeds to S205. If the second hierarchy does not exist, the process ends.

  In step S <b> 205, the control unit 105 acquires display data for the menu items related to the second hierarchy from the memory 107. The data is converted into an appropriate display form by the display processing unit 106, and the transparency is changed to a predetermined value, for example, 20% by the transmission processing unit 109. Then, a signal indicating the menu item related to the second hierarchy is output to the monitor 200 via the output unit 104 (S206).

  FIG. 3 shows a state in which menu items in the first hierarchy are displayed as menu items 301 to 305 in a non-transparent manner. At this time, the initial selection item of the first hierarchy is the menu item 301, and in the figure, the selection state is distinguished by a thick frame line. Then, the menu items in the second layer related to the initial selection items in the first layer are displayed as the menu items 306 to 310 with a transparency of 20%. At this time, the menu items 306 to 310 are displayed so as to be superimposed on the menu item of the first hierarchy so that the user can easily understand the hierarchical structure. Note that the menu items 306 to 310 are indicated by a horizontal line in the drawing that they are displayed with a transparency of 20%.

  Next, using FIG. 4 and FIG. 5, an operation when the selection item of the first layer is changed with respect to the menu display in the broadcast receiving apparatus 100 will be described. FIG. 4 is a flowchart illustrating an operation example of the broadcast receiving apparatus 100 when a change instruction is given to a selection item on the first layer by a user operation. FIG. 5 shows an example of the display screen, in which the items 2-1 to 5 of the second layer related to the item 2 are displayed together with the items 1 to 5 of the first layer.

  An instruction to change the selection item by a user operation using a remote controller or the like is notified to the control unit 105 via the input unit 108 (S401). The control unit 105 changes the selection item of the first hierarchy. In FIG. 5, the change to the item 2 of the first hierarchy is indicated by a thick frame line. After the changed data is converted into an appropriate display form in the display processing unit 106, a signal indicating the menu item of the first hierarchy is output to the monitor 200 via the output unit 104 (S402).

  Based on the menu item display data stored in advance in the memory 107, the control unit 105 determines whether or not there is a next layer (second layer) with respect to the changed selection item of the first layer (second layer) ( S403). As a result, if there is a second hierarchy regarding the selection item of the first hierarchy, the process proceeds to S404. If the second hierarchy does not exist, the process ends.

  In S404, the control unit 105 acquires display data for menu items related to the second hierarchy from the memory 107 (S404). The data is converted into an appropriate display format by the display processing unit 106, and then the transparency is changed to a predetermined value, for example, 20% by the transmission processing unit 109. A signal indicating the menu item of the second hierarchy is output to the monitor 200 via the output unit 104 (S405).

  In the example of FIG. 5, menu items in the first hierarchy are displayed as menu items 301 to 305, and a thick frame line indicates that the selected item is the menu item 302. Menu items in the second layer corresponding to the menu item selected in the first layer are displayed as menu items 306 to 310 with a transparency of 20% (indicated by a horizontal line in the figure). The menu items 306 to 310 are displayed so as to be superimposed on the menu items in the first hierarchy so that the user can easily grasp the hierarchical structure.

  Next, using FIG. 6 and FIG. 7, the operation when the selection item of the first hierarchy is determined for the menu display in the broadcast receiving apparatus 100 will be described. FIG. 6 is a flowchart showing an operation example of the broadcast receiving apparatus 100 when the user gives an instruction to determine a selection item of the first hierarchy. FIG. 7 shows an example of the display screen. Items 1 to 5 relating to the first hierarchy, items 2-1 to 5 relating to the second hierarchy, and items 2-1-1 to 5 relating to the third hierarchy are displayed. The state that was done is shown.

  An instruction to determine a selection item by a user operation using a remote controller or the like is notified to the control unit 105 via the input unit 108 (S601). The control unit 105 instructs the display processing unit 106 to convert the data of the menu items related to the first hierarchy into an appropriate display form, and then the transparency processing unit 109 sets the transparency to a predetermined value, for example, 70%. To change to. A signal indicating the menu item of the first layer is output to the monitor 200 via the output unit 104 (S602).

  The control unit 105 instructs the display processing unit 106 to convert the data of the menu item related to the second hierarchy into an appropriate display form, and then the transparency processing unit 109 sets the transparency to zero, that is, non-transparency. Instruct to change. A signal indicating the menu item in the second hierarchy is output to the monitor 200 via the output unit 104, and the menu item is displayed in a non-transparent manner (S603).

  Based on the menu item display data stored in advance in the memory 107, the control unit 105 determines whether or not there is a next layer (third layer) for the initial selection item of the second layer (S604). . If there is a third hierarchy for the initial selection item of the second hierarchy, the process proceeds to S605. If the third hierarchy does not exist, the process ends.

  In step S <b> 605, the control unit 105 acquires display data for menu items related to the third hierarchy from the memory 107. The data is converted into an appropriate display form by the display processing unit 106, and the transparency is changed to a predetermined value, for example, 20% by the transmission processing unit 109. A signal indicating the menu item of the third hierarchy is output to the monitor 200 via the output unit 104 and displayed on the screen (S606).

  In the example of FIG. 7, menu items in the first layer are displayed as menu items 301 to 305 with a transparency of 70%. At this time, an item determined in the first hierarchy is indicated by reference numeral 302, and the determined state is indicated by being surrounded by a dotted thick frame. Note that the state in which the menu items 301 to 305 are displayed with a transparency of 70% is indicated by vertical lines in the drawing.

  Menu items in the second layer corresponding to the menu items determined in the first layer are displayed as non-transparent menu items 306 to 310, and these are superimposed on the first layer so that the user can easily grasp the hierarchical structure. Is displayed. At this time, the selection item of the second hierarchy is indicated by reference numeral 306, and the selection state is indicated by being surrounded by a thick frame line. Menu items in the third layer corresponding to the menu items selected in the second layer are displayed as menu items 311 to 315 with a transparency of 20% (indicated by a horizontal line in the figure). These are displayed superimposed on the menu item of the second hierarchy so that the user can easily understand the hierarchical structure.

  Thereafter, in the same manner, each time a menu item of the next layer is selected and a determination operation is performed, each layer is displayed on the screen with a different transparency. For example, if the selected hierarchy is displayed with a transparency of 70%, the currently selected hierarchy is displayed as non-transparent, and there is a next hierarchy corresponding to the currently selected item, the next hierarchy is transparent. Displayed at 20%. If there is no next hierarchy corresponding to the currently selected item, this is not displayed, so the user can immediately recognize that it is the last hierarchy.

  As described above, according to the present embodiment, in the hierarchical menu, the selected first hierarchy, the currently selected second hierarchy, and the third hierarchy that is the next hierarchy of items belonging to the selected second hierarchy are the same screen. Display with different transparency for each level in the area. For example, in the above-described embodiment, the currently selected hierarchy is displayed in a non-transparent manner, and the next hierarchy corresponding to the currently selected item is displayed lighter than the currently selected hierarchy (transparency 20%). The selected hierarchy is displayed lighter than the next hierarchy of the currently selected item (transmittance 70%). Thus, the user can instantly and easily grasp menu items of three levels including the selected level, the level currently selected, and the next level corresponding to the selected item. Therefore, user operability is improved.

  In the present embodiment (first embodiment), the transparency 70% and 20% of each layer is merely an example, and any value can be used as long as each layer can be visually distinguished. . In the above example, the transparency of the selected hierarchy is all displayed at 70%. However, the present invention is not limited to this, and the transparency in the selected hierarchy may be changed and displayed. For example, when the third hierarchy is currently selected, the first hierarchy and the second hierarchy are the selected hierarchies. In this case, it is not necessary to uniformly define the transparency of the first hierarchy and the second hierarchy as 70%, and the transparency of the first hierarchy may be 80% and the transparency of the second hierarchy may be 70%. That is, it is preferable that the transparency of the selected hierarchy is changed and displayed within a range in which the next hierarchy corresponding to the item being selected can be distinguished. This makes it easier for the user to visually determine the hierarchy order of the selected hierarchy due to the difference in transparency.

  Further, the present invention is not limited to the embodiment in which the layers are displayed in a superimposed manner, and the layers may be displayed adjacent to each other. The display size of each hierarchy is not specifically mentioned, but the size of the selected hierarchy, the currently selected hierarchy, and the next hierarchy corresponding to the selected item are different so that the size of each display area is different. May be changed.

  Next, a second embodiment of the present invention will be described. In the first embodiment, display is performed by changing the transparency of each layer in the hierarchical menu. On the other hand, in the second embodiment, in the selected hierarchy in which the transparency is changed, the color of the selected item and the item not selected is changed and displayed. Since the initial display operation of the menu is the same as that in the first embodiment, detailed description thereof is omitted.

  FIG. 8 is a flowchart showing an operation example of the broadcast receiving apparatus 100 when the user gives an instruction to determine a selection item in the first hierarchy. FIG. 9 shows an example of the display screen. Items 1 to 5 related to the first hierarchy, items 2-1 to 5 related to the second hierarchy, and items 2-1-1 to 5 related to the third hierarchy are shown. It is displayed.

  An instruction to determine a selection item by a user operation using a remote controller or the like is notified to the control unit 105 via the input unit 108 (S901). The control unit 105 instructs the display processing unit 106 to convert the data of the menu item related to the first hierarchy into an appropriate display form, and then the transparency processing unit 109 sets the transparency to a predetermined value, for example, 70%. (S902). Thereafter, the display processing unit 106 changes the display color of the menu item determined in the first hierarchy to a predetermined color. A signal indicating the menu item of the first layer is output to the monitor 200 via the output unit 104 (S903).

  The control unit 105 instructs the display processing unit 106 to convert the data of the menu item related to the second hierarchy into an appropriate display form, and then instructs the transparent processing unit 109 to change to non-transparent. . Then, a signal indicating the menu item in the second hierarchy is output to the monitor 200 via the output unit 104, and the item is displayed (S904).

  The control unit 105 determines whether or not there is a next layer (third layer) corresponding to the initial selection item of the second layer based on the menu item display data stored in the memory 107 in advance ( S905). As a result, if there is a third layer corresponding to the initial selection item of the second layer, the process proceeds to S906. If the third hierarchy does not exist, the process ends.

  In step S <b> 906, the control unit 105 acquires menu item data related to the third hierarchy from the memory 107. The data is converted into an appropriate display form by the display processing unit 106, and the transparency is changed to a predetermined value, for example, 20% by the transmission processing unit 109. A signal indicating the menu item of the third hierarchy is output to the monitor 200 via the output unit 104, and the item is displayed (S907).

  In the example of FIG. 9, menu items in the first layer are displayed as menu items 301 to 305 with a transparency of 70% (indicated by vertical lines in the figure). An item to be determined in the first layer is indicated by reference numeral 302, which is shown as being hatched in the broken line frame as a state where the transparency is 70% and the color is changed. Menu items in the second hierarchy corresponding to the menu items determined in the first hierarchy are displayed as menu items 306 to 310 in a non-transparent manner. The selected item in the second hierarchy is a menu item 306 as shown by a thick frame. Menu items in the third layer corresponding to the menu items selected in the second layer are displayed as menu items 311 to 315 with a transparency of 20% (indicated by a horizontal line in the figure).

  As described above, according to the second embodiment, in the hierarchical menu, the selected hierarchy, the currently selected hierarchy, and the next hierarchy corresponding to the item of the selected hierarchy are different on the display area of the same screen. It is possible to distinguish and display according to transparency and display color. For example, the selected hierarchy is displayed with 70% transparency, the currently selected hierarchy is displayed with non-transparency, the next hierarchy corresponding to the selected item is displayed with 20% transparency, and the selected hierarchy has been selected. Selected items in the hierarchy are displayed in a different color from the other items. Accordingly, the user can visually grasp the selection status of the three layers as a difference in transparency, and in the selected layer where the transparency is changed, only the item selected by the user can be easily visually determined. Therefore, user operability is enhanced.

  In the second embodiment, the display color of the item selected in the selected hierarchy is changed to a color different from that of the unselected item. However, the present invention is not limited to this. As a modified example, a form in which the color (lightness, saturation, hue) of the next layer corresponding to the selected layer, the currently selected layer, and the selected item is changed and displayed may be adopted. . In this case, for the menu display operation, the display processing unit 106 performs color setting, so the transparency processing unit 109 does not change the transparency.

FIG. 10 shows an example of a display screen when the user gives an instruction to determine a selection item in the first hierarchy after the menu is displayed.
In FIG. 10, menu items in the first hierarchy are displayed as menu items 301 to 305 in a predetermined color. As for the determination items in the first hierarchy, as shown by reference numeral 302, the determination state is shown surrounded by a thick dotted line. Menu items in the second hierarchy corresponding to the menu items determined in the first hierarchy are displayed as menu items 306 to 310 in a color different from that in the first hierarchy. The selection item in the second hierarchy is a menu item 306, and the selection state is indicated by being surrounded by a thick frame. Menu items in the third layer corresponding to the menu item selected in the second layer are displayed as menu items 311 to 315 in a color different from that in the first and second layers.

  The display processing unit 106 displays the currently selected hierarchy displayed as the menu items 306 to 310 with a certain reference color. For the next level corresponding to the currently selected item displayed as the menu items 311 to 315, the menu item is displayed in a color having a lower brightness than the currently selected level (the hatched line in the figure). ). In addition, the selected hierarchy displayed as the menu items 301 to 305 is displayed in a color having a lower brightness than the menu items 311 to 315 (indicated by diagonal grid lines in the drawing).

  Thereafter, in the same manner, the menu item color of each layer is changed each time the menu item of the next layer is selected and determined. In other words, when the currently selected layer is displayed in a certain reference color, the menu item of the next layer corresponding to the selected item is displayed in a color having a lower brightness than the display color of the currently selected layer. . The selected hierarchy is displayed in a color having a lower brightness than the display color of the next hierarchy corresponding to the currently selected item. Thereby, it becomes easy for the user to visually recognize the three layers instantaneously, and thus the operability for the user is enhanced.

Note that, as an example of the operation of the broadcast receiving apparatus 100 when an instruction to determine a selection item in the first layer is performed, in each step shown in the flowchart of FIG. 8, the change in the transparency is changed in the change in the brightness of the display color. It should be read and applied.
In addition, the user can visually distinguish the currently selected hierarchy, its upper hierarchy, and lower hierarchy by changing not only the brightness of the display color of each hierarchy but also hue, saturation, or a combination thereof. You may comprise as follows. Further, it is not necessary to display all the menu items of the selected hierarchy with the same brightness, and the brightness, hue, and saturation may be changed and displayed with respect to the display color of each item in the selected hierarchy. Or you may change only the color of the item after selection and determination similarly to 2nd Embodiment.

  Next, a third embodiment of the present invention will be described. In the first embodiment, items are displayed by changing the transparency of each layer in the hierarchical menu. At this time, depending on the viewing environment of the user, the visibility of the hierarchy displayed with increased transparency may be reduced. Therefore, when the illuminance in the viewing environment of the user deviates from a certain range, it is desirable that the transparency is appropriately adjusted and displayed for the selected hierarchy, its upper and lower hierarchies. In the menu display operation according to the third embodiment, the transparency is changed based on the illuminance of the viewing environment when the transparency processing unit 109 performs the transparency setting process after the display processing unit 106 performs the process. Since matters other than this are the same as in the case of the first embodiment, a detailed description thereof will be omitted.

  FIG. 11 is a block diagram illustrating a configuration example of a broadcast receiving apparatus according to the third embodiment. The difference from the configuration shown in FIG. 1 is that an illuminance sensor 110 is provided to detect ambient illuminance. Therefore, elements similar to those in FIG. 1 are denoted by the same reference numerals and detailed description thereof is omitted.

  In the broadcast receiving device 400, the illuminance sensor 110 detects ambient illuminance and sends the detection result to the control unit 105. Whether the illuminance detection information input from the illuminance sensor 110 is outside the range (allowable range) defined by the threshold value when the control unit 105 displays the menu or receives a menu display instruction from the input unit 108. Determine whether. When it is determined that the illuminance detection information is outside this range, the control unit 105 causes the transmission processing unit 109 to change the transparency of each layer so that the menu is appropriately displayed via the display processing unit 106. . A signal indicating the menu item of each layer whose transparency is adjusted in this way is output to the monitor 200 via the output unit 104.

FIG. 12 is a flowchart illustrating an operation example of the broadcast receiving device 400 when the ambient illuminance changes. The flowchart on the left illustrates menu display processing (S1303 to S1307), and the flowchart on the right illustrates illumination detection information processing (S1301, S1302), which are processed in parallel.
First, the control unit 105 acquires illuminance detection information of the current viewing environment from the illuminance sensor 110 (S1301). Then, the control unit 105 stores illuminance data indicating the current illuminance in the memory 107 (S1302).

  On the other hand, the control unit 105 determines whether or not menu display is currently being performed (S1303). As a result, if it is determined that the menu is being displayed, the process advances to step S1304, and the control unit 105 acquires the illuminance data stored in step S1302 from the memory 107 and advances to step S1305. If the menu is not displayed, the process ends.

  In step S1305, the control unit 105 determines whether or not the illuminance of the current viewing environment is within an allowable range determined by a certain threshold based on the acquired illuminance data. As a result, when the illuminance of the current viewing environment is brighter than the allowable range, the process proceeds to S1306. Here, the control unit 105 instructs the transparency processing unit 109 via the display processing unit 106 to change the transparency of the menu display, and displays the menu in a state where the transparency is lower than the standard value. If the illuminance of the current viewing environment is darker than the permissible range, the process proceeds to S1307. Here, the control unit 105 instructs the transparency processing unit 109 via the display processing unit 106 to change the transparency of the menu display and display the menu in a state where the transparency is higher than the standard value.

After the processes in steps S1306 and S1307, or when it is determined in S1305 that the illuminance of the current viewing environment is within the allowable range, the process returns to S1303.
As described above, according to the third embodiment, when it is determined that the illuminance in the viewing environment is out of a certain range, the transparency of each layer is adjusted and menu display is performed in an appropriate state. That is, by adjusting the transparency of the selected hierarchy, the currently selected hierarchy, and the next hierarchy corresponding to the currently selected item based on the illuminance information, adaptive control with respect to the viewing environment of the user can be realized. Thereby, it is possible to prevent the visibility of the layer on which the transparent display has been performed from being significantly lowered when the user operates the menu.
