Description

  The present invention relates to an image display apparatus capable of remote control, such as a television receiver and a video recorder apparatus.

  In recent years, multi-channel television broadcasting and the combination with video tape recorders have progressed, and a remote control device (hereinafter referred to as a remote control) that can remotely control AV equipment linked to the television device in a unified manner is required. It came to be. For this reason, if only one key is associated with one function of the remote control device, the keys are insufficient, and it is unavoidable that one key has two or more functions, or a large number of keys are arranged in a certain area. In order to do this, measures such as placing a small key were taken.

  However, in this case, it is necessary for the user to learn two or more functions for one key, and it is necessary to select a large number of small keys, which is not easy to operate.

  On the other hand, conventionally, an apparatus has been proposed in which an icon is selected from a touch panel provided on a remote controller and a signal is transmitted to an image display device (see, for example, Patent Document 1). The technique will be briefly described below.

When selecting an icon on the screen with a finger in such a remote control, the support of the finger is not stable, causing a subtle trembling, and for this reason, the selected icon when touching near the boundary between the icon and the icon The display is not stable and the display changes according to the trembling of the finger. In order to solve this problem, the conventional technique is provided with menu display means for displaying a menu composed of a plurality of icons for remote control on the screen, and the menu and coordinates displayed on the screen on the remote control are provided. Correspondingly, there is provided an image display device provided with a touch panel for selecting the icon displayed by the menu display means, and a region that does not reflect a change in the selection state of an icon having a predetermined width on the boundary between adjacent icons ( Intermediate zone).

  The touch panel on the remote control as described above prevents the display from changing according to the trembling of the finger when touching near the border of the icon. If the dead zone is selected, it will be misunderstood that the user does not respond even if the user points. When the pointing cursor is displayed on the screen, it can be recognized that the user is touching the vicinity of the boundary and can be corrected by shifting toward the center of the icon, but cannot be recognized when not displayed.

  In order to solve the above-described problems, the present invention provides an image display device that is remotely controlled by a remote control device, and a menu display that displays a menu including a plurality of icons for remote control on the image display device. In the image display device provided with a touch panel for selecting the icon displayed on the menu display unit corresponding to the menu displayed on the screen and coordinates corresponding to the remote control device, the icons are adjacent to each other. If the icon has an intermediate area with a predetermined width at the boundary with the icon to be touched, and the adjacent icon is not selected when the intermediate area is pointed, the icon corresponding to the coordinates of the touch panel is selected, and the adjacent icon The icon selection state does not change when any of the above is in the selection state.

  According to the image display device of the present invention configured as described above, even when an icon for function operation is selected by touching the touch panel with a finger, the user does not feel uncomfortable in the selection operation and reliably A selection decision operation can be performed.

(Embodiment 1)
An example of an embodiment of the present invention is shown in FIGS. FIG. 1 is a diagram showing the screen states of the remote controller and the image display device in Embodiment 1 of the present invention. FIG. 2 is a diagram showing an example of an operation menu according to Embodiment 1 of the present invention. FIG. 3 is a diagram showing details of the coordinate system of the operation menu according to Embodiment 1 of the present invention.

  First, FIG. 1 is a conceptual diagram showing a concept of operation. In FIG. 1, 1 is a remote control device (hereinafter referred to as a remote controller), and performs remote control of the image display device 2. The remote control signal is not limited to infrared rays, radio waves, and the like.

  The remote controller 1 includes a touch panel 5 and a switch 6. The switch 6 may be a minimum necessary switch such as a power switch. Of course, the switch 6 may be omitted. An operation menu 4 is displayed on the normal screen on the screen 3 of the image display device 2. When the user touches the touch panel 5 while looking at the operation menu 4 and presses the decision switch 7 on the icon to be selected, the operation menu 4 is converted into an icon. A command for executing the function is sent from the remote controller 1 to the image display device 2, and the image display device 2 executes the command.

  In addition, although the determination switch is arrange | positioned on the surface in FIG. 1, the arrangement | positioning in particular is not limited.

  The coordinates (x, y) on the touch panel 5 on the remote controller 1 correspond to (x, y) shown in the operation menu 4 in the screen 3 of the image display device 2.

  Next, details of the operation menu 4 will be shown by way of an example. FIG. 2 corresponds to the operation menu 4 when operating the video recorder. At this time, when the user is reproducing the video recorder, the reproduction menu 8 is displayed. The playback menu 8 includes icon areas 9a to 9d on which icons for executing the respective functions of rewind, fast forward, stop, and still are displayed. When the user touches the touch panel 5 on the remote controller 1, the color of the icon corresponding to the touched portion changes, and the user is notified that the icon is selected. If the determination switch 7 is pressed in a state where an icon of a function operation desired by the user is selected, a desired function is realized.

  Next, FIG. 3 shows a user's selection operation. The intermediate band 10 as an area that does not reflect the change in the icon selection state is arranged with a predetermined width at the boundary of the icon. Hereinafter, the characteristic operation of the present invention will be described with reference to FIG.

  First, when the user touches (x1, y1), since the user touches the icon area 9b that is not on the intermediate band, any of the icon areas 9a to 9d is not selected or any one is selected. Even in this state, the fast-forward operation corresponding to the icon area 9b is selected. As a matter of course, it is determined that the operation is continued when the fast forward is already selected.

  When the user touches (x′1, y′1), the icon region on the intermediate band is touched, so that the following operation is performed. If any of the icon areas 9a to 9d is not selected, the adjacent icon areas 9a and 9b of the intermediate band to which the coordinates belong are not selected. Therefore, the icon area 9b corresponding to the coordinates of the touch panel is displayed. Selected. Here, when either icon region 9a or 9b is in the selected state, the icon selection state does not change because one of the adjacent icons in the intermediate band is in the selected state. When the user touches (x′1, y′1), even if the icon regions 9c and 9d are selected, the adjacent icon in the intermediate band is not selected, so the icon in the icon region 9b Is selected.

  Next, even if the user moves his / her finger to (x2, y2) on the intermediate band and touches the icon area 9a, the icon selection does not change because the icon area 9b adjacent to the intermediate band is selected. You still have selected fast forward.

  Next, when the user moves his / her finger to (x3, y3), the user touches the icon area 9a that is not on the intermediate band, so that the rewind operation corresponding to the icon area is selected.

Although the above operation has been described by taking a specific icon area as an example, it goes without saying that the same operation is performed in the other icon areas as well. One of the icons is selected by the selection operation, and there is no sense of incongruity that the device does not respond to the operation. However, once one of the icons is selected, the user's finger is in the selected icon area, for example when the finger is touching near the border of the icon, the selection will try to respond to a slight movement of the finger. However, as long as it has the structure of this invention, the selection state is stable without reacting. When selecting an icon that is sufficiently distant from the icon area in the selected state, the icon is selected by touching the icon area to which the selected icon belongs. Therefore, the operation is performed with the above-described stability. I don't feel uncomfortable that I don't respond.

  The image display device according to the present invention can be reliably selected and operated without making the user feel uncomfortable, and is useful in an image display device that can be controlled remotely.
