Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a media image display method, and more particularly to a media image display method of a system that displays a media image on a display screen and outputs a media corresponding to the image by instructing a predetermined image.
[0002]
[Prior art]
There is a system that displays a number of media images on a display screen, selects a desired media image, and causes a system (apparatus) to perform an operation according to the media image. For example, a CD, TV broadcast, radio broadcast, or the like to be selected for listening or viewing is a medium, a CD player with changer, a TV tuner, a radio tuner, or the like, which converts the media into a visual / audio signal. Is a case where a plurality of media images are displayed on a display screen, a desired media image is selected, the media is converted into a visual / audio signal, and output.
In such a system, a media image can be moved from an initial display position to an arbitrary position by an operator operation, and the media images can be grouped according to the type, or can be displayed in an overlapping manner according to the frequency of use of the media images. It has become.
[0003]
FIG. 7 is a schematic explanatory diagram of the movement and overlay display method. In the figure, 51a to 53a are media images, 51b to 53b are layers (layer 1 to layer 3), and 54 is a display screen. The media images 51a to 53a displayed so as to be superimposed on the display screen 54 are managed as existing on independent layers, that is, layers 1 to 3 respectively. Each layer has a layer number, and the image on the display screen 54 is displayed on the front side of the display screen with priority given to those existing in the upper layer. In FIG. 7, the media image 53a of layer 3 which is the highest layer is displayed on the near side with respect to the display screen, and then displayed in the priority order of the media image 52a and the media image 51a. Accordingly, the overlapping parts on the display screen are displayed with priority on the one with the highest priority (in the highest layer). That is, for each picture element constituting each media image, it is checked whether it overlaps with the media image of the upper layer. If it does not overlap, “display” is displayed, and if it overlaps, “display is not performed”, display region data Is created.
[0004]
Each media image moves on the layer to which the image belongs. For example, the media image 52a moves on the layer 2 and is displayed on the display screen according to the above rules. In addition, when the moving media image and the media image overlapping on the display screen are completely different before and after the movement, the moving media image has been changed to the highest layer, and has existed in the highest layer. For the media image, the existence layer is changed to the next lower layer, and thereafter, the existence layer is similarly changed for all media images up to the media image existing in the layer one layer higher than the layer where the moving media image exists.
Thereby, the moving media image can be displayed on the front of the display screen. Therefore, the media image can be moved from the initial display position to an arbitrary position by an operator's operation, and the media images can be grouped according to the type, or can be freely superimposed and displayed depending on the usage frequency of the media image.
[0005]
Each media image is provided with a media table. (1) Media ID unique to the media image, (2) Layer number of the layer to which the media image belongs, (3) Media image data, (4) Display position data , (5) display area data (data indicating visible and invisible areas) and the like are stored. Therefore, the layer number stored in the media table is referred to in order of priority, and the layer to which the member belongs at the time of movement is changed.
[0006]
Each media image is input to the system control unit from the input device, displayed at an initial position on the display screen, and then moved to a predetermined position by an operator operation. That is, when a new outputable medium is generated, the input device notifies the system control unit and sends a media image. The system control unit creates a media table and displays the media image on the forefront of the initial position of the display screen that is predetermined for the input device. Thereafter, the operator moves and displays the media image at a predetermined position by operating the mouse or the like. For example, in an in-vehicle audio-visual system, if the received electric field strength of a certain TV broadcast channel becomes equal to or higher than a set value and reception of the TV channel broadcast (media) becomes possible, the TV tuner notifies the system control unit accordingly. And send a media image. The system control unit creates a media table and displays the media image on the forefront of the initial position of the display screen corresponding to the TV tuner. After that, the media controller makes it easy to operate the media. The images are moved to a position where the same type of media image is displayed and grouped, and the other media images of the same group are superimposed and displayed at that position. The same type includes, for example, a classical music group, a pop music group, a news program group, a sports program group, a traffic information group, and the like.
[0007]
[Problems to be solved by the invention]
By the way, a media image corresponding to all media that can be output from each input device is displayed on the display screen, and is further displayed in groups according to the contents of the media. For this reason, it may be difficult for the user to grasp the correspondence between the media image and the input device. For example, when it is desired to listen to news output from a radio tuner, a large number of media images using news as media are displayed, making it difficult to select media images corresponding to radio news.
In view of the above, an object of the present invention is to provide a media image display method that can clarify the correspondence between an input device and a media image and can easily select a media of a desired input device.
[0008]
[Means for Solving the Problems]
According to the present invention, a plurality of media images that specify media that can be output are displayed on a display screen, and the image is specified by indicating one of the plurality of media images. In a media image display method of a system for outputting media, for each media, a table is provided to hold a relationship between the media and an input device that converts the media into an audio signal or a visual signal, and images of a plurality of input devices are provided on a display screen. When an image of one input device among the images of the plurality of input devices is designated, the table is searched for media that is converted into an audio signal or a visual signal by the input device. Only the media image of the selected media is left on the display screen, Erase the media images from the display screen, the return operation is achieved by a media image display method for displaying media image the erased display screen.

When the above standby information setting is completed for all the input devices, the user operates the input unit 16 to display the system screen. When there is a system screen display request from the input unit 16, the input device controls the input / output switching unit 17 to connect the display unit 15 and the input unit 16 to the system control unit 12. Notify that there was an operation request.
When receiving the notification, the system control unit 12 redisplays the system screen 15a immediately before switching to the input device screen on the display unit 15.
[0021]
In the state where such a system screen is displayed, when any medium cannot be output, the system control unit 12 refers to the standby information of the media ID stored in the media table 13. When the standby information indicates that the management is to be abandoned, the media save screen is displayed at the display position of the media image to delete the media image, and all the management information of the media is stored from the media table 13. delete.
On the other hand, when the standby information indicates continuation of management, the system control unit 12 deletes the media image of the media from the system screen, but retains the management information of the media without deleting it from the media table 13.
Then, when the media that can no longer be output can be output again, the display position data and display area data registered corresponding to the media ID of the media are obtained by referring to the media table 13, and the media is stored at the position. The media image is displayed. That is, the media image is displayed again at the display position of the media image displayed previously.
[0022]
Further, when the user selects the target media input device using the input unit 16 and requests the display of only the media image of the input device while the system screen is displayed, the system control unit 12 Searches for the device ID of the input device selected from the device management table 14. When the device ID is obtained, the system control unit 12 determines whether all media in the media table 13 have an input device ID that matches the obtained device ID. Then, the media image continues to be displayed for the media having the matching input device ID, and the saved image is displayed at the media image position and erased from the display screen for the media not having the input device ID.
[0023]
FIG. 6 shows a change in display screen display before and after the request when a predetermined input device image is selected and display of only the media image of the input device is requested. The dotted line indicates the media image position that has been displayed so far for convenience, and is not actually displayed.
As described above, if only a media image related to the target media input device is displayed on the display screen and a desired media is selected, the input device outputs the audio output of the media corresponding to the media image. Or perform visual output.
If the same input device is selected again and the return is instructed, the system control unit 12 refers to the media table and displays the erased media image at the original display position.
The present invention has been described with reference to the embodiments. However, the present invention can be variously modified in accordance with the gist of the present invention described in the claims, and the present invention does not exclude these.
