Description

  The present invention relates to a video apparatus such as a television receiver, and more particularly to a video apparatus in which a setting screen is displayed on a monitor by an OSD (On Screen Display).

  In a television receiver (hereinafter, referred to as “TV”), a setting screen is OSD-displayed over a main video so that a user can set menu items even while viewing a program. The user operates the remote controller on this setting screen to make various settings such as screen brightness, contrast, hue, language, channel, timer recording, and change the settings.

  By the way, such a setting screen (hereinafter referred to as “OSD setting screen”) displayed by the OSD is displayed so as to be superimposed on the main video, so that the main screen is displayed while the OSD setting screen is displayed. It is inevitable that part of the video is hidden and disappears. For this reason, there is no problem if the main video can be partially hidden. However, if the main video is a scene that the user wants to see, it is inconvenient for the user to hide a part of the main video on the OSD setting screen. is there.

  Therefore, when a scene to be viewed appears in the middle of the setting, the desired scene can be viewed without being disturbed by the setting screen by operating the remote controller to delete the OSD setting screen once. However, with the conventional TV, if the OSD setting screen is deleted by operating the remote control, the previous setting information is also deleted at the same time, so if you try to reset after the scene you want to watch, You have to start over, which is very cumbersome for users.

  As a countermeasure, it is conceivable that the OSD setting screen is made transparent (that is, the transparency is set to 100%) while keeping the setting information as it is. Patent Documents 1 to 3 described later describe the transparency of the OSD display. Japanese Patent Application Laid-Open No. 2004-228561 discloses a video device in which the size, position, and transmittance of the OSD setting screen can be freely changed to a user-desired level so that the program video being viewed is not hindered. In Patent Document 2, when a program video being viewed and an information display screen such as an EPG (Electronic Program Guide) are superimposed and displayed, information requiring visibility is transmitted through the program video. A broadcast receiving apparatus has been disclosed in which the display information is displayed and the other information is displayed in a transparent manner with respect to the program video, thereby improving the visibility of the display information while maintaining the visibility of the program being viewed. In Japanese Patent Laid-Open No. 2004-228688, television reception is achieved by ensuring the visibility of the OSD without being affected by the brightness of the main image by changing the transparency of the OSD according to the brightness of the main image in the display area of the OSD. A machine is disclosed.

  If the OSD transparency processing is performed while retaining the setting information, the OSD setting screen is made invisible (erased) by remote control operation, and the setting screen is displayed again after the scene to be viewed is finished, and then resetting is performed. Since there is no need to re-set from the beginning, it is possible to save the user's trouble.

  However, once you clear the OSD settings screen and view the desired scene, if you forget to redisplay the settings screen by operating the remote control, the settings remain suspended until the user notices them. Will not be changed. In addition, some users may be suspicious that the settings are not reflected because they misunderstand that the settings have been completed even though the settings are in a suspended state. For such a problem, no effective solution is presented in Patent Documents 1 to 3 described above.

  In view of the above-described problems, the present invention provides a video device that can be reliably reset by the user even if the OSD setting screen is made transparent and erased, and the setting screen is forgotten to be re-displayed. The purpose is to do.

A video device according to the present invention includes a tuner that extracts a signal of a predetermined channel from a broadcast signal, a signal processing unit that processes the signal extracted by the tuner, and a video based on the video signal processed by the signal processing unit. A monitor to be displayed, an OSD processing unit that generates an OSD (On Screen Display) setting screen that is displayed on the monitor so as to be superimposed on the video, an operation unit for performing settings on the OSD setting screen, and the operation unit And a control unit that controls the display on the monitor based on the above operation, and the operation unit has a delete button for deleting the OSD setting screen. When the delete button is operated during the setting on the setting screen, the control unit makes the OSD setting screen invisible while keeping the setting information set on the operation unit. Thereafter, when a predetermined operation is performed on the operation unit, the OSD setting screen immediately before erasure is displayed on the monitor at that time. When a predetermined operation is not performed on the operation unit, the OSD setting screen immediately before deletion is displayed on the monitor when the broadcast content is changed after the OSD setting screen is deleted.

In this way, when the delete button is operated in the middle of setting, the OSD setting screen becomes transparent and the main video is displayed unobstructed on the setting screen, and the OSD setting screen immediately before deletion is displayed by a predetermined operation thereafter. Is displayed on the monitor, the user does not need to set again from the beginning, and the troublesomeness is eliminated. In addition, even if you had forgotten that you once erase the OSD setting screen, at the time when the OSD setting screen there is a change in the broadcast content after it has been deleted, since the OSD setting screen of erase just before is displayed on the monitor, for example When the broadcast content is shifted to commercials, the user can reliably perform resetting.

  As a predetermined operation for displaying the OSD setting screen immediately before the deletion on the monitor, for example, it is conceivable to operate the deletion button again. According to this, after erasing the OSD setting screen by operating the erasing button once and then operating the erasing button once more, the setting screen immediately before erasing is displayed on the monitor.

In the above video equipment, the control unit prompts the user to select whether or not to continue the setting together with a warning that the setting remains interrupted when the broadcast content is changed after the OSD setting screen is deleted. When the display is performed and the setting continuation is selected, the OSD setting screen immediately before erasure may be displayed on the monitor. According to this, it is possible to reliably notify the user that the setting has been interrupted, and the subsequent processing can be smoothly performed by selecting whether or not to continue setting by the user.

  According to the present invention, it is possible to provide a video device that can be reliably reset by the user even if the user forgets to redisplay the setting screen after clearing and erasing the OSD setting screen.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In this example, an LCD is used as the monitor 5, but a monitor such as a CRT (cathode ray tube) or a PDP (plasma display panel) can be used instead of the LCD.

  8 is a microcomputer for controlling the operation of the television 100 (hereinafter referred to as “microcomputer”), 9 is a remote control receiving unit for receiving a signal transmitted from the remote controller 15, 10 is a memory composed of ROM, RAM, etc., 11 Is a display unit made up of an LED (light emitting diode) or the like provided in the main body of the television 100, 12 is an operation unit also provided in the main body of the television 100, 13 is a power supply unit that supplies power to each unit, and 14 is a signal processing unit 3. An OSD processing unit that generates an OSD (On Screen Display) setting screen that is superimposed on the video signal and displayed on the monitor 5.

  In the above, the microcomputer 8 and the memory 10 constitute one embodiment of the control unit in the present invention, and the remote controller 15 and the operation unit 12 constitute one embodiment of the operation unit in the present invention.

  Although only the configuration of the television is shown in FIG. 1, the television 100 may be a composite television incorporating a DVD (Digital Versatile Disk) deck or a VCR (Video Cassette Recorder) deck, for example. In this case, a DVD block including a DVD recording / reproducing unit and a VCR block including a video tape recording / reproducing unit are added to the configuration of FIG.

  FIG. 2 is an external view showing an example of the remote controller 15. The configuration of FIG. 2 is also common to the embodiments. 51 is a power button for turning on / off the power of the television 100, 52 is a menu button for displaying a menu screen which is an initial screen of the OSD setting screen (described later) on the monitor 5 of the television 100, and 53 is for erasing the OSD setting screen. An erasing button 54, a cursor button for selecting a predetermined item on the menu screen, 55 a determination button for determining an item selected by the cursor button 54, and 56 a numerical value button. The remote controller 15 is provided with various buttons other than these, but since they are not directly related to the present invention, description of other buttons is omitted.

  Next, the procedure for erasing and redisplaying the OSD setting screen in the television 100 will be described with reference to FIGS. 3A to 3I.

  FIG. 3A shows a state in which the main video 5a of the broadcast program is displayed on the screen of the monitor 5 of the television 100. In this state, when the menu button 52 (FIG. 2) of the remote controller 15 is pressed, the main menu screen 21 which is the initial screen of the OSD setting screen is displayed so as to be superimposed on the main video 5a on the screen of the monitor 5. The main menu screen 21 displays menu items such as channels, settings, and languages.

  Next, when the cursor button 54 of the remote controller 15 is operated to move the cursor to, for example, “setting” among the menu items on the main menu screen 21 and then the enter button 55 is pressed, the screen of the monitor 5 is displayed on the screen. A submenu screen 22 as shown in 3C is displayed. On this submenu screen 22, menu items such as a screen, age, and password are displayed. “Screen” is selected when setting the brightness, contrast, etc. of the screen, “Age” is selected when setting the age when viewing restrictions are set according to the program contents, and “Password” is canceled viewing restrictions Selected when setting the password.

  If the main video 5a of the broadcast program is switched to the main video 5b as shown in FIG. 3D while the submenu screen 22 is displayed, the user disturbs the main video 5b on the submenu screen 22. If the user wants to see the video without being pressed, the user presses the erase button 53 of the remote controller 15 once. Then, the transparency of the OSD constituting the sub menu screen 22 becomes 100%, the sub menu screen 22 becomes transparent, and disappears from the screen as shown in FIG. 3E. As a result, the entire main image 5b is displayed without being partially hidden.

  Thereafter, when the video of the broadcast program is switched again and the main video 5c as shown in FIG. 3F is displayed, if the user does not particularly need the main video 5c, the user presses the erase button 53 once again. . Then, the transparency of the OSD constituting the submenu screen 22 becomes 0%, the submenu screen 22 returns to the original state, and the submenu screen 22 immediately before erasure (FIG. 3D) is the main video as shown in FIG. 3G. 5c is displayed in an overlapping manner. Therefore, the user does not need to operate the menu button 52 of the remote controller 15 again to display the main menu 21 (FIG. 3B) and perform the operation again from the beginning, and continues setting on the redisplayed submenu screen 22. Just do it.

  By the way, as described above, if the delete button 53 is operated again after deleting the submenu screen 22, the submenu screen 22 is displayed. If the user forgets to operate the delete button 53 again, Until the user notices it and operates the delete button 53, the menu item setting remains suspended. However, in this embodiment, even if the user forgets to re-operate the delete button 53, when a button operation is performed on the remote controller 15 such as channel switching or volume adjustment after that, the message screen 23 as shown in FIG. Is superimposed on the currently viewed main video 5d and displayed in OSD.

  On this message screen 23, a “Yes” or “No” button prompting selection of whether or not to continue is displayed together with a warning “Settings are still suspended. Do you want to continue?”. Here, when the user operates the remote controller 15 to select “Yes”, as shown in FIG. 3I, the submenu screen 22 immediately before erasure (FIG. 3D) is displayed again superimposed on the main video 5d. Settings can be continued on the menu screen 22. Even in this case, the user does not need to perform setting again from the beginning. On the other hand, when “No” is selected on the message screen 23, the submenu screen 22 is not displayed, and the setting contents up to that point are cancelled.

  As described above, in this embodiment, when the delete button 53 is pressed once during the setting, the OSD setting screen (here, the submenu screen 22) becomes transparent, and the main video is displayed on the setting screen without being disturbed. Then, by pressing the erasing button 53 once again, the OSD setting screen immediately before erasing is displayed on the monitor 5, so that the user does not need to redo the setting from the beginning, and the troublesomeness is eliminated. Even if the user has forgotten that the OSD setting screen has been erased, the message screen 23 is displayed when the next button is operated, so that the user knows that the setting has not been completed. Since the setting screen is redisplayed by selecting the setting continuation on the message screen 23, the setting can be completed with certainty.

  FIG. 4 is a flowchart showing a procedure for deleting and redisplaying the OSD setting screen described above. This procedure is executed by the microcomputer 8 based on a program stored in a predetermined area of the memory 10.

  When the broadcast of the program is started (step S1), it is monitored whether or not the setting operation has been performed (step S2). If the setting operation has not been performed (step S2: NO), the process returns to step S1. If the setting operation is performed by pressing the menu button 52 of the remote controller 15 during the program broadcast (step S2: YES), the process proceeds to step S3 to monitor the OSD setting screen (in this case, the main menu screen 21). (FIG. 3B). Then, it is determined whether or not the setting by the operation of the remote controller 15 has been completed (step S4). If the setting has not been completed (step S4: NO), the delete button 53 of the remote controller 15 is pressed in the next step S5. It is determined whether or not it has been done. If the delete button 53 is not pressed (step S5: NO), the process returns to step S3, and steps S3 to S5 are repeatedly executed while the setting is not completed and the delete button 53 is not pressed.

  When the setting is completed in step S4 (step S4: YES), the process proceeds to step S9, executes processing according to the setting content, and then returns to step S1. Further, when the setting is not completed (step S4: NO) and the delete button 53 is pressed (step S5: YES), the process proceeds to step S6, the transparency of the OSD setting screen is set to 100%, and the setting screen is made transparent. It becomes invisible (FIG. 3E). At this time, the setting information up to that point is retained in the memory 10 without being erased.

  Thereafter, it is monitored whether or not the delete button 53 of the remote controller 15 is pressed again (step S7), and if it is not pressed (step S7: NO), it is monitored whether or not any other button is pressed (step S7). If no other button is pressed at step S10a) (step S10a: NO), the process returns to step S7, and steps S7 and S10a are repeatedly executed until there is a button operation.

  In step S7, when the delete button 53 is pressed again (step S7: YES), the process proceeds to step S8, and the OSD setting screen immediately before the deletion is displayed on the monitor 5 (FIG. 3G). Then, the process returns to step S4. If the setting is not completed (step S4: NO), steps S5, S3, and S4 are repeatedly executed. If the setting is completed (step S4: YES), step S9 is executed. After that, the process returns to step S1.

  In step S7, if the delete button 53 is not pressed again (step S7: NO) and any other button is pressed (step S10a: YES), the process proceeds to step S11 and the message screen 23 is displayed on the monitor 5. Is displayed and a warning is given (FIG. 3H). Then, it is determined whether or not to continue the setting (step S12). When “Yes” is selected on the message screen 23 in FIG. 3H, it is determined that the setting is continued (step S12: YES), the process proceeds to step S8, and the OSD setting screen immediately before the deletion is displayed on the monitor 5 (FIG. 3I). ). Then, the process returns to step S4, and the procedure described above is executed thereafter. On the other hand, if “No” is selected on the message screen 23 in FIG. 3H, it is determined that the setting is not continued (step S12: NO), and the setting is canceled (step S13). At this time, the previous setting information stored in the memory 10 is deleted. After executing step S13, the process returns to step S1 to execute the above-described procedure.

  FIG. 5 is a flowchart showing another embodiment of the present invention. In the present embodiment, step S10a in FIG. 4 is replaced with step S10b. In step S10b, it is determined whether or not a predetermined time has elapsed since the OSD setting screen was deleted. The time is measured by, for example, a timer (not shown) built in the microcomputer 8. When the predetermined time has elapsed (step S10b: YES), the message screen 23 is displayed on the monitor 5 (step S11), and by selecting to continue the setting (step S12: YES), the OSD setting screen is displayed. (Step S8). The other steps are the same as those in FIG.

  According to the present embodiment, if the user forgets to erase the OSD setting screen once, the message screen 23 is automatically displayed after a predetermined time even if no operation is performed thereafter. It can be seen that the setting is incomplete. Since the setting screen is redisplayed by selecting the setting continuation on the message screen 23, the setting can be completed with certainty.

  FIG. 6 is a flowchart showing still another embodiment of the present invention. In the present embodiment, step S10a in FIG. 4 is replaced with step S10c. In step S10c, it is determined whether or not the broadcast content has been changed after the OSD setting screen has been erased. As a change of the broadcast content, for example, a case in which a commercial is included in a program can be considered. In order to detect the shift to the commercial, a method for detecting switching to the sound multiplex mode (for example, Japanese Patent No. 2858758) or a method for detecting by using a silent section and a scene change (for example, Japanese Patent Publication No. 6). No. -66738) can be used. When the broadcast content is changed (step S10c: YES), the message screen 23 is displayed on the monitor 5 (step S11). By selecting setting continuation (step S12: YES), the OSD setting screen is displayed. It is displayed (step S8). The other steps are the same as those in FIG.

  According to the present embodiment, even if the user forgets to delete the OSD setting screen once, the message screen 23 is automatically displayed when the broadcast content is changed, so the user has not completed the setting. I understand that. Since the setting screen is redisplayed by selecting the setting continuation on the message screen 23, the setting can be completed with certainty.

  In the present invention, various embodiments other than those described above can be adopted. For example, in the above embodiment, when the OSD setting screen is deleted, the screen is made completely transparent and invisible, but as shown in FIG. 7, while the OSD setting screen is being deleted, the outline 30 of the setting screen is displayed. May be displayed in an inconspicuous color to notify the user that the setting is incomplete.

  In each of the above embodiments, when the predetermined timing is reached (steps S10a to 10c), the message screen 23 is first displayed (step S11), and whether or not to continue setting is selected on the screen (step S12). Although the OSD setting screen is redisplayed (step S8), steps S11 and S12 may be omitted and the OSD setting screen may be redisplayed immediately when a predetermined timing is reached.

  4 to 6 are integrated, and when the delete button 53 is not operated again in step S7, (1) any button other than the delete button 53 is operated, and (2) OSD. A message screen 23 is displayed when any of the following conditions is met: a certain time has elapsed since the setting screen was deleted, or (3) the broadcast content was changed after the OSD setting screen was deleted. Or a specification that directly redisplays the OSD setting screen may be adopted.

  Furthermore, in the above-described embodiment, a television is taken as an example of a video device, but the present invention is not limited to a television and can be applied to other video devices such as a DVD recorder.
