It is characterized by that.

  According to the present invention having such a feature, when the user is familiar with the device, the user can display the next screen by pressing the enter key before a predetermined time (for example, 5 to 10 seconds) elapses. Since the process proceeds, the corresponding part (for example, the corresponding page) is not displayed. On the other hand, for those who are unfamiliar with the device, if you get lost looking at the menu screen, the corresponding page of the instruction manual will be displayed when a certain time has elapsed, so the user can open the corresponding page of the instruction manual, It becomes possible to know the contents of the item. That is, according to the present invention, it is possible to display the corresponding page in consideration of the user's proficiency with respect to the electronic device, that is, the user's operation status. That is, the corresponding page of the instruction manual can be displayed only when the user is really at a loss in selecting an item.

  In this case, the display control means may be configured to display the corresponding item of the instruction manual for all items while displaying the item on which the cursor is located differently from the other items. . If the cursor is at one item position, it is considered that the user is at a loss as to whether or not that item is acceptable. In this case, the display color of the corresponding page of the instruction manual is displayed only for that item. Make it different. For example, the other items are displayed in black, and the item where the cursor is positioned is displayed in red. As a result, the corresponding page can be highlighted in accordance with the operation status of the user.

  Further, according to the present invention, the display control means displays an inquiry screen as to whether or not to refer to a corresponding location (corresponding page) being displayed. A configuration may be adopted in which the display state of the screen is controlled so as to ensure a time longer than a predetermined time. The menu screen or the like is normally stopped (erased from the screen) when a predetermined time (for example, 1 minute) elapses without any operation. However, if it is selected to refer to the corresponding page of the instruction manual, naturally, it takes time to read the page, and during that time, the user does not operate the menu screen. In such a case, if the display is erased from the screen just after the predetermined time has elapsed, when the user finishes reading the manual and proceeds to the next operation, the menu screen is displayed again.

The corresponding page of the instruction manual for the item is displayed beside each item on the menu screen when a certain time has elapsed. At this time, in this embodiment, the cursor is positioned. Items are displayed with different display colors from other items. That is, in the example shown in FIG. 2C, the cursor 51 is positioned at the item “PICTURE”, and therefore “page 12” of the corresponding page displayed next to “PICTURE” is displayed in red, for example. Then, “page 9” and “page 23” of the corresponding page displayed beside the other items “CH SETUP” and “TIMER” are displayed in black, for example. As a result, it is possible to highlight the corresponding page of the item that the user thinks he or she is confused about.

  The fifth embodiment is an embodiment when the user selects on the menu screen to refer to the corresponding page displayed in each of the first to fourth embodiments. Normally, the menu screen or the like is set in advance so that the display is stopped (erased from the screen) when a predetermined time (for example, 1 minute) elapses without any operation. The fifth embodiment is an embodiment relating to the handling of the predetermined time. However, the case where the fifth embodiment is applied to the display example of the first embodiment will be described.

  That is, after the menu screen is displayed, when a certain time has elapsed without pressing the enter key (when it is determined Yes in step S4 in FIG. 2), the microcomputer 21 passes the certain time as shown in FIG. Sometimes the corresponding page of the instruction manual for the item is displayed next to the item on which the cursor 51 is positioned on the menu screen, and “reference” is written to confirm whether or not to refer to the corresponding page. The confirmation button is displayed together. In this example, it is displayed next to “PICTURE” (page 12) where the cursor 51 is located.

  Here, when the user operates the remote control transmitter 41 and selects the “reference” button, the microcomputer 21 sets a predetermined time (for example, 1 minute) that is a default value of the display time of the menu screen (that is, the menu off time). Etc.) is changed to a longer period such as 3 minutes. In other words, the display state of the menu screen is maintained for 3 minutes without any operation on the menu screen. This time change is made to return to the normal default value (1 minute or the like) again when an arbitrary item is selected on the menu screen.

  If it is selected to refer to the corresponding page of the instruction manual, naturally, it takes time to read the page, and during that time, the user does not operate the menu screen. In such a case, if a predetermined time (for example, 1 minute), which is the default value, has passed and the display is erased from the screen, the user has finished reading the instruction manual and proceeds to the next operation. At that time, the menu screen must be displayed again. In the fifth embodiment, in order to save such a user's trouble, when referring to the corresponding page of the instruction manual is selected, the display duration of the menu screen is set from a normal predetermined time (for example, 1 minute). For example, 3 minutes or longer. Thereby, the screen display according to a user's operation condition is attained.

  The sixth embodiment is an embodiment where the corresponding page is displayed in each of the first to fourth embodiments, and then the item displaying the corresponding page is selected. However, the case where the sixth embodiment is applied to the display example of the first embodiment will be described.

  That is, as shown in FIG. 2B, when the corresponding page is displayed next to the item at the cursor 51 position, when the user selects the item on which the corresponding page is displayed (in this example, “PICTURE”), The microcomputer 21 controls the OSD circuit 24a, and proceeds to an image quality adjustment screen for items such as “TINT (color)”, “COLOR (color)”, and “BRIGHT (brightness)” as shown in FIG. . In this case, as shown in FIG. 2B, if the corresponding page is displayed next to “PICTURE” on the menu screen, when the image quality adjustment screen is displayed, as shown in FIG. In addition, each corresponding page may be displayed next to each item at the same time. That is, the subsequent screen display may be sequentially performed in accordance with the display state of the previous screen.

  On the other hand, as shown in FIG. 7B, when the process proceeds to the next image quality adjustment screen, the corresponding page may not be displayed at that time and the process of FIG. 2 may be executed again. That is, the page may be displayed as shown in FIG. 7C only when the enter key is not pressed even after a predetermined time has elapsed. In this example, the corresponding page is displayed only beside the “COLOR (color)” item where the cursor 51 is located. This is a display example according to the second embodiment, and all the items are displayed. The corresponding page may be displayed on the side.

  Also, when returning from the image quality adjustment screen to the previous menu screen, two display modes can be considered. One is to return to the screen with the corresponding page displayed as shown in FIG. 2 (b), and the other is to display the corresponding page as shown in FIG. 2 (a). In this case, the screen returns to the conventional menu screen.

  In each of the first to sixth embodiments, the fixed time is described as being set in advance. However, the fixed time may be arbitrarily set by the user. This makes it possible to display the corresponding page of the instruction manual according to the usage of each individual user.

  Further, in each of the first to sixth embodiments described above, the configuration is described in which the corresponding page of the instruction manual, which is a booklet, is displayed as the corresponding portion corresponding to each item on the menu screen. 29 is stored as electronic data and is displayed on the display unit 26 for reference, as shown in FIGS. 8A and 8B, it corresponds to each item on the menu screen.
