Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a media image display method, and more particularly, to a media image of a system for displaying a media image on a display screen and instructing a predetermined image to output the media according to the image. Regarding display method.

[0002]

2. Description of the Related Art There is a system in which a large number of media images are displayed on a display screen, a desired media image is selected, and a system (apparatus) performs an operation according to the media image. For example, a media, a CD player with a changer, a TV tuner, a CD, a TV broadcast, a radio broadcast, or the like, which is a selection target for listening or viewing,
In an audio-visual system having an input device that converts the above media into a visual / audio signal, such as a radio tuner, a plurality of media images are displayed on a display screen, and a desired media image is selected to visualize the media. This is a case of converting into an audio signal and outputting. In such a system, a media image can be moved from an initial display position to an arbitrary position by an operator operation, the media images can be grouped according to the type, and the media images can be freely overlapped and displayed depending on the frequency of use. Has become.

FIG. 7 is a schematic explanatory view of the moving and superposing display method. In the figure, 51a to 53a are media images, 5
1b to 53b are layers (layers 1 to 3), and 54 is a display screen. The media images 51a to 53a displayed in an overlapping manner 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 images on the display screen 54 are 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 front side of the display screen, and then the media image 52a and the media image 51a are displayed in order of priority. Therefore, in the overlapping portion on the display screen, the one having the highest priority (in the highest layer) is preferentially displayed. That is, for each picture element that constitutes each media image, it is checked whether or not it overlaps with the media image of the upper layer. If it does not overlap, it is “displayed”.
By doing so, the display area data is created.

The movement of 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 rule. If the moving media image and the overlapping media image on the display screen are completely different before and after the movement,
The existing layer of the moving media image changes to the uppermost layer, and the existing media image of the uppermost layer changes the existing layer to a layer one layer below, and thereafter, one layer higher than the layer where the moving media image existed. Similarly, the existing layer is changed for all the media images up to the media image existing in the layer. This allows the moving media image to be displayed in front of the display screen. Therefore, the media image can be moved from the initial display position to any position by operator operation,
Media images can be grouped according to the type, and can be freely overlapped and displayed depending on the frequency of use of the media images.

A media table is provided for each media image, and a media ID unique to the media image,
Layer number of the layer to which the media image belongs,
Media image data, display position data, display area data (data indicating a visible area and an invisible area), etc. are stored. Therefore, referring to the layer numbers stored in the media table, the layers are displayed in order of priority, and the layer to which the user belongs when moving is changed.

Each media image is input to the system control unit from an input device, displayed at an initial position on the display screen, and then moved and displayed at a predetermined position by an operator's operation. That is, when a new outputable medium is generated, the input device notifies the system control unit of that fact and sends a media image. The system control unit creates a media table and displays the media image on the foreground of the initial position of the display screen which is predetermined corresponding to 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 TV field broadcast (media) can be received when the reception electric field strength of a TV broadcast channel exceeds a set value, the TV tuner notifies the system control unit to that effect. And the media image is sent. The system control unit creates the media table and displays the media image on the foreground of the initial position of the display screen that is predetermined corresponding to the TV tuner, and thereafter, the media is displayed for easy operation by the operator. The image is moved to a position where a media image of the same type is displayed and grouped, and the image is superimposed and displayed at the position on another media image of the same group. The same type is, for example, a classical music group, a pop music group, a news program group, a sports program group, a traffic information group, and so on.

[0007]

By the way, on the display screen, media images corresponding to all media that can be output from each input device are displayed, and further, they are grouped and displayed according to the contents of the media. Therefore, it may be difficult for the user to grasp the correspondence between the media image and the input device. For example, when listening to news output from a radio tuner, a large number of media images with news as media are displayed, and it becomes difficult to select a media image corresponding to radio news. From the above, it is an object of the present invention to provide a media image display method which can clarify the correspondence between an input device and a media image and can easily select the medium of a desired input device.

[0008]

According to the present invention, there are provided means for displaying a media image corresponding to a medium that can be output on a display screen, and conversion of the media into an audio signal or a visual signal at a predetermined position on the display screen. Means for displaying images from multiple input devices,
When a predetermined input device is instructed, only the media image of the medium converted into the audio signal or the visual signal by the input device is left on the display screen, and the means for deleting other media images from the display screen, output by the return operation Means for displaying possible media images on the display screen.
