Description

  The present invention relates to a display device having an operation menu display function.

  In recent years, with the advancement of performance and multi-functionality of television receivers, etc., a microcomputer is used to display a device operation menu on the CRT, and menu items are selected by a remote controller or the like to operate the device. However, it has been widely practiced.

  By the way, conventional display devices with menus for operation have little experience since they are used, and the performance of microcomputers is low, so the operation procedure is complicated and the menu structure is difficult. For this reason, there are problems that it takes a long time to operate and an operation error tends to occur.

  Here, an example of a conventional display device with a menu for operation will be described.

  FIG. 14 shows a block diagram thereof. In FIG. 14, reference numeral 401 denotes an input device, which includes an infrared remote controller or the like, and a user, for example, a television viewer, can input an operation to the device by pressing a key on the remote controller or the like. Reference numeral 407 denotes a display device that includes a CRT and displays video images and menus. Reference numeral 402 denotes an input receiving unit that receives a key input from the input device 401. Reference numeral 406 denotes an internal state control unit, which controls the internal state of the device, for example, changing the selected channel of the television. A menu structure management unit 404 manages the structure of the operation menu and the internal state and display data corresponding to the menu items.

  A menu control unit 403 generates, changes, and deletes an operation menu according to the menu structure managed by the menu structure management unit 404 in accordance with an instruction from the input reception unit 402, and displays the operation menu on the display device 407. The display content is controlled, and at the same time, the internal state control unit 406 is requested to change the internal state. Reference numeral 405 denotes an operation guidance display control unit. The menu structure management unit 404 obtains an operation guide related to the menu item being operated in the operation menu being displayed by the menu control unit 403, and the operation guide is displayed on the operation menu 403. Are displayed on the display device side by side, and the display contents are controlled. In addition, the display device generally requires various components, but they are omitted because they are not the gist of the present invention.

  The specific operation of the conventional display device with an operation menu configured as described above will be described with reference to FIGS. FIGS. 15 and 16 are flowcharts showing an example of the operation of the display device with an operation menu according to the conventional technique. FIGS. 17 to 20 specifically show an example of a change in the display screen of the display device with an operation menu according to the prior art. 17 to 20, the same reference numerals are used for the same parts.

  In this conventional example, the operation menu basically has a two-level tree type hierarchical structure. As shown in FIG. 17, the input device 410 has at least an up / down cursor key 611 for changing the selected menu item, a left / right cursor key 612 for changing the content of the selected menu item, and goes down the menu hierarchy. There is a determination key 613 for returning and a menu key 614 for returning to the highest menu hierarchy.

  The menu display unit 602 in the display device 601 already displays the highest level of the operation menu, and “sound adjustment” is the currently selected menu item. The operation guidance display unit 603 displays operation guidance corresponding to the currently selected menu. At this point, the user does not know what menu is included in the lower hierarchy of each menu item unless the menu item is entered.

  On the other hand, menu items that are used infrequently and menu items that are used frequently are included in the same second layer, which causes a large amount of information to be displayed on the screen and causes confusion for the user.

  Here, when the “change of the selected menu item by the user” shown in FIG. 15 occurs when the up / down cursor key 611 of the input device 401 is pressed, the “selection menu item by the user” is transferred from the input receiving unit 402 to the menu control unit 403. The menu control unit 403 refers to the menu structure management unit 404, updates the display of the selected menu, requests the operation guidance control unit 405 to update the operation guidance display, The operation proceeds to “change operation guidance” shown in FIG. 15, and the display screen is in the state shown in FIG. In this case, “video adjustment” is selected. If such a change of the selection menu item is repeated continuously, the change of the operation guidance is repeated at the same time, and the display is rewritten at a high speed, which hinders the user's operation.

  Furthermore, when the operation is advanced by pressing the enter key 613 and enters the hierarchy of the “video adjustment” menu, the display screen becomes the state shown in FIG. In this case, “color density” is selected, and its internal state is “+30”. At this point, it is difficult for the user to recognize in which hierarchy the currently displayed menu is located in the menu structure. In addition, when each menu item is operated for the user, it is necessary to read the instruction manual attached to the device to determine what effect the actual item has on the device.

  In order to display a menu other than “adjust video”, the menu key 614 is pressed once to return to the highest menu level, and the menu item is selected again by pressing the up / down cursor key 611 and determined. A complicated operation of pressing the key 613 is required.

In FIG. 19, when the “change of the selected menu item content by the user” of FIG. 16 is generated by pressing the left / right cursor key 612 of the input device 401, the “input menu selection by user” is displayed from the input reception unit 402 to the menu control unit 403. The menu control unit 403 refers to the menu structure management unit 404 to obtain the internal state corresponding to the currently selected menu item, and sends the internal state to the internal state control unit 406. Is requested, and the display is updated at the same time, the display screen becomes the state shown in FIG. In this case, “color density” is selected, and its internal state is “+29”. At this point, assuming that the internal state of “color tone” has been rewritten from an external device by a system input terminal such as that provided in a television receiver, for example, the menu control unit 403 in FIG. There is a discrepancy between the “color tone” information and the “color tone” internal state of the actual device.

When the menu switch key 315 is pressed again, the display of the “image automatic adjustment” menu is deleted, and the display screen returns to the state shown in FIG.

  (2) Next, another operation of the present invention will be described. When the display screen is in the state shown in FIG. 7 and the “request for handling explanation by user” shown in FIG. 4 is generated by pressing the handling explanation key 313, the internal state management unit shown in FIG. Handling instructions corresponding to 109 are displayed, and the display screen is in the state shown in FIG. Since this handling explanation reflects the internal state of the device of the internal state management unit 109 in FIG. 1, the display contents differ depending on the internal state.

  (3) Other operations will be described. The index display section 304 in FIG. 7 indicates that there are four types of menus that can be selected with the index key 314: “Frequently Used”, “Sub-screen”, “Adjustment”, and “Setting”, and in particular, “Adjustment” is highlighted. Indicates that the menu is currently selected. When the “menu selection by index” shown in FIG. 5 occurs when the index key 314 is pressed from the state shown in FIG. 7, the menu display is switched according to a specific rule, and another menu in the same hierarchy is displayed. And it will be in the state of FIG. In this case, “Frequently Used” is the currently selected menu. Note that “menu selection by index” can be generated from the menu control unit 103 in FIG. 1 in addition to user input from the input device 101 in FIG. 1.

  (4) As another embodiment, when the “change in internal state” shown in FIG. 6 occurs from the state shown in FIG. 12, the internal state management unit 109 shown in FIG. 1 changes and the display is updated. The display screen is in the state shown in FIG. The “change in the internal state” is generated independently of the input device 101 from the user, for example, by control from an external device such as a system input terminal equipped in the television receiver. In this case, although the menu selection item is “BS reservation”, the display of the “tone-to-speech” menu item is changed from “stereo” to “monaural”.

  (5) Further, as shown in FIG. 11, the menu display unit 302, the operation guidance display unit 303, the index display unit 304, and the handling explanation display unit 305 are displayed in a continuous area with an image like “book”. It is displayed. The display content of each display unit is once received by the display content synthesis unit 110 of FIG. 1 and is synthesized into a “book” image in a continuous area and displayed on the display device 301.

  (6) Finally, the operation of the embodiment shown in FIG. 9 will be described. In the state of FIG. 9, operation guidances “value change” and “detailed setting” are indicated on the operation guidance display unit 303. Here, when the up / down cursor key 311 is pressed and the "change of the selected menu item by the user" shown in FIG. 2 occurs and the selected menu item moves down, the state returns to the state of FIG. The display of 303 is only “change value”. The time measurement unit 114 starts time measurement from the time when the up / down cursor key 311 or the left / right cursor key 312 is pressed.

  Therefore, when such an operation is continuously performed, the operation time interval of the up / down cursor key 311 or the left / right cursor key 312 is shorter than the time during which an interrupt request is sent from the time measurement unit 114 to the operation guidance control unit 105. In this case, the operation guidance control unit 105 does not update the display. However, if the time interval until the next operation becomes longer than the time during which an interrupt request is sent from the time measurement unit 114 to the operation guidance control unit 105, the display is updated.

As described above, in the display device with an operation menu according to the present invention, the menu can be configured so that frequently used menu items can be changed immediately, and the less frequently used menu depends on the proficiency level of the user. Can be used. In addition, handling instructions and operation guidance according to the current state of the device can be shown without disturbing the screen. In addition, the index allows a menu to be easily and immediately selected from a complicated menu hierarchy.
