The main CPU and its peripheral circuit 3 serve as a control circuit for controlling the entire system. The flash memory 4 is a portion in which moving image data and character data for displaying information on a selected device and its function (hereinafter, referred to as a function) are stored in advance. The moving image data is, for example, a set of a plurality of image data having different angles with respect to a character representing each device, and displaying the plurality of image data sequentially at a fixed time interval to display a moving image. An image can be constructed. The character data is, for example, character shape data (font data) constituting a character string (hereinafter, referred to as a function title) representing each device or its function, and is defined as three-dimensional point data assuming a 3D space. ing.

As a specific example of a character and a character string, C
In the case of a D player, a moving image of a CD and “CDPLAY
In the case of an MD player, a moving image of an MD and a character string of “MDPLAYER” are used, and in the case of a radio, a moving image of a microphone and a character string of “TUNER” are used. The contents of the flash memory 4 are written at the time of shipment from the factory, and are always retained even when the power is turned off.

The graphic memory 5 is a portion where data to be displayed on the display unit 7 is written. The graphic chip 6 is a part that sends a video signal to the display unit 7 with reference to the graphic memory 5 in which data is written in response to a display command from the main CPU and its peripheral circuit 3. The display unit 7 is a unit that displays a moving image based on a video signal from the graphic chip 6, and may use, for example, an LCD. The display unit 7
Also functions in the same manner as the input unit 2.

[1-2. Role of Main CPU and its Peripheral Circuit] Further, the main CPU and its peripheral circuit 3
The software is configured to function as the following components shown in FIG. 1 by the operation of the software described above. That is, the function detection unit 30 is
This is a means for detecting the function selected and input by. The search unit 31 is a unit that searches the flash memory 4 for image data (including moving image data and character data) corresponding to the function detected by the function detection unit 30. For example, when it is detected that one function is selected, character data constituting a character string corresponding thereto and moving image data representing a character are searched.

The three-dimensional moving image calculation section 32 is means for performing a calculation for displaying a three-dimensional moving image based on the retrieved character data. In this calculation, the character is theoretically moved in the 3D space by setting and changing the viewpoint, the distance, the light source, and the like for the character, and the character is converted into plane coordinates and drawn. For example, it can be realized by geometry operations such as coordinate transformation and perspective transformation used in graphics such as computer games.

Is displayed, but details thereof are omitted.

[2. Operation of Embodiment] [2-1. Overall Processing] The procedure of the image display processing according to this embodiment as described above will be described below. First, the overall flow of the processing will be described with reference to the flowchart in FIG. That is, after turning on the power of the system or using a specific function, the user selects and inputs a desired function using the input unit 2 when switching from the currently selected function to another function (step S1). 201). Then, the function detection unit 30 detects the selected and input function (step 202). The search unit 31 searches the image data stored in the flash memory 4 for image data corresponding to the detected function (Step 203). If the searched image data is character moving image data (step 204), the moving image data is written to the graphic memory 5 by the writing control unit 33 (step 206).

If the retrieved image data is character shape data corresponding to the selected function and needs to generate a three-dimensional moving image (step 204), a three-dimensional moving image calculation is performed based on the shape data. The operation by the unit 32 is performed (step 205), and the data of the operation result is written into the graphic memory 5 (step 20).
6).

Further, the display controller 34 instructs the graphic chip 6 to display (step 207). Graphic chip 6 receiving display instruction
Is a graphic memory 5 in which image data is expanded.
, The video signal is sent to the display unit 7, so that the display unit 7
In, display based on the video signal is performed (step 208).

Here, the timing at which the still image and the moving image are displayed is in accordance with an instruction from the display timing control unit 34a. The position where the image is displayed on the display unit 7 follows the instruction of the display position control unit 34b. At the same time as the above-mentioned display is performed, the main CPU and its peripheral circuit 3 also issue a command to the selected electronic device 1 and, for example, in the case of switching from a television to a CD player, Function switching is performed.

[2-2. Moving Picture Display Example] Next, an example of a concrete moving picture display will be described with reference to the flowchart of FIG. 3 and screen display examples of FIGS. First, when a function is selected, a function title (for example, CDPLAYER) corresponding to the function is displayed in FIG.
As shown in (1), a large three-dimensional display is first performed over the entire surface (step 301). Next, this function title:
As shown in FIG. 5, the user retracts from the near side to the back near the center of the screen (step 302), and then temporarily stops (step 303). Then, as shown in FIG. 6, the characters making up the function title are further retracted further into the back while being scattered for each character (step 30).
4). The mode of the movement and the character spacing at the time of the fragmentation may be a preset pattern or may be random. Further, as shown in FIG. 7, the function titles go deeper and align, and stop at a certain place (step 305).

During the stop, the moving picture data of the character corresponding to the function is developed in the graphic memory 5 (step 306). And FIG.
As shown in the figure, first, the front image of the character is displayed at the center of the screen, and the function title starts moving from the left back of the screen toward the front. ) Is displayed (step 307). Here, the front image (first frame) of the character is displayed for a predetermined period of time so that it is recognized as a still image so that the user can identify what image. Thereafter, as shown in FIG. 9, the character starts to rotate (step 308). On the other hand, the function title is displayed so as to flow from the back left side of the screen toward the front so as not to overlap with the central character, and stops when the front of the screen is fully filled (step 309).

It should be noted that, for example, the character is stored as a picture in which the character makes one rotation divided into 24 patterns, and the characters are rotated in a frame-by-frame manner. Displaying in such a way as to make one round in about 1.5 seconds is considered as one example. Further, the display time of the still image at the beginning of the character display can be freely set. For example, the display time can be set as follows.
That is, the moving image data is once read into the graphic memory 5 for drawing and then displayed.
Since it takes time to read a plurality of pieces of image data, the reading time is such that a moving image is displayed by displaying the first still image and repeating the display sequentially after the reading is completed.

That is, instead of simply displaying the still image of the first frame until the predetermined time elapses, the remaining 23 frames of data are stored in the graphic memory 5 using the display time of the still image. To expand to By doing so, the character display can be performed quickly because only the first frame need be developed immediately after the function switching, instead of developing 24 frames at a time. Thereafter, a moving image is displayed by displaying the second and subsequent frames at a fixed time interval, and until the function is switched again, the moving image display is always performed at a constant interval.

The function title flowing to the viewer at the same time as the display of the character is stopped when it reaches the position near the front of the screen. Are displayed so as not to overlap each other.

[3. Effects of Embodiment] According to the above-described embodiment, since the function title and the character representing the selected function are displayed as a moving image, the function selected by the user can be easily recognized and visually enjoyed. And help create a comfortable feeling of operation and the atmosphere inside the car. In addition, since the function title and the character are displayed as a still image at the beginning of the display, the function can be easily confirmed when the function is selected.
In particular, by writing moving image data to the graphic memory 5 using the still image display time, the first still image can be quickly displayed immediately after the function switching, so that a moving image display that requires a memory or the like can be displayed. Even if there is, display delay can be prevented.

Also, since the function can be recognized by the meaning represented by the function title and the function can be intuitively recognized by the character, the user can recognize the function regardless of the viewing position, the angle, the state of the moving image, and the like. Function can be recognized accurately. Further, since the display of the function title and the character do not overlap, mistakes such as erroneous recognition of the function are prevented.
