Note that the touch panel provided in the display unit 7 also functions in the same manner as the input unit 2.
[0019]
[1-2. Role of main CPU and its peripheral circuits]
Further, the main CPU and its peripheral circuit 3 are configured to serve as the following parts shown in FIG. 1 by the operation of the software as described above. That is, the function detection unit 30 is means for detecting a function selected and input by the input unit 2. 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 has been selected, character data constituting a corresponding character string and moving image data representing a character are searched.
[0020]
The three-dimensional moving image calculation unit 32 is a means for performing a calculation for displaying a three-dimensional moving image based on the retrieved character data. In this calculation, a character is theoretically moved in 3D space by setting and changing the viewpoint, distance, 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 calculation such as coordinate transformation and perspective transformation used in graphics such as computer games. The write control unit 33 is means for writing data to be displayed on the display unit 7 to the graphic memory 5.
[0021]
The display control unit 34 is a means for instructing the graphic chip 6 to display an image.

Have. When displaying the moving image on the display unit 7, the display timing control unit 34 a can specify the timing for displaying the moving image data for each frame developed in the graphic memory 5 based on the timer function of the system. it can. For example, the moving image display can be realized by displaying the moving image data of 24 frames developed in the graphic memory 5 one frame at a time interval specified by the display timing control unit 34a. Still image display can also be performed by continuing to display a specific frame for a longer time than the interval for moving image display.
[0022]
The display position control unit 34b can control the display positions of characters and characters so as not to overlap each other. Such control is realized, for example, by defining X and Y data for 2D plane coordinates so as not to overlap intentionally. The main CPU and its peripheral circuit 3 control the actual operation of each electronic device 1 (for example, device switching, reproduction, stop, etc.) and the state of each electronic device 1 (for example, reproduction time, reception frequency, etc.). ) Is displayed, but details thereof are omitted.
[0023]
[2. Operation of the embodiment]
[2-1. Overall processing)
The procedure of the image display process according to the present embodiment as described above will be described below. First, the overall flow of processing will be described with reference to the flowchart of FIG. That is, the user selects and inputs a desired function using the input unit 2 when the user wants to switch from the currently selected function to another function after turning on the system or using a specific function (step S2). 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 retrieved image data is character moving image data (step 204), the moving image data is written into the graphic memory 5 by the write control unit 33 (step 206).
[0024]
When the retrieved image data is character shape data corresponding to the selected function and it is necessary to generate a 3D moving image (step 204), the 3D moving image calculation unit 32 performs the processing based on this shape data. An operation is performed (step 205), and data of the operation result is written in the graphic memory 5 (step 206).
[0025]
Further, the display control unit 34 instructs the graphic chip 6 to display (step 207). The graphic chip 6 that has received the display instruction refers to the graphic memory 5 in which the image data is developed and sends a video signal to the display unit 7, so that the display unit 7 performs display based on the video signal ( Step 208).
[0026]
Here, the timing at which the still image and the moving image are displayed follows the instruction of 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. Further, at the same time as the above 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 practice, such as switching from a television to a CD player. The function is switched.
[0027]
[2-2. (Video display example)
Next, an example of a specific moving image display will be described with reference to the flowchart of FIG. 3 and the screen display examples of FIGS. First, when a function is selected, a function title (for example, CDPLAYER) corresponding to the function is initially displayed in large three-dimensional form on the entire surface as shown in FIG. 4 (step 301). Next, as shown in FIG. 5, the function title is retracted from the front to the back near the center of the screen (step 302), and then temporarily stopped (step 303). Then, as shown in FIG. 6, the characters constituting the function title are further retracted while being separated for each character (step 304). The mode of movement and character spacing when falling apart may be a preset pattern or random. Furthermore, as shown in FIG. 7, the function titles go inward and align, and stop at a certain place (step 305).
[0028]
During this stop, the moving image data of the character corresponding to the function is developed in the graphic memory 5 (step 306). Then, as shown in FIG. 8, first, the front image of the character is displayed in the center of the screen, and the function title starts moving from the left back of the screen toward the front, and the state data (for example, the selected function) , Playback time, etc.) are displayed (step 307). Here, the front image of the character (first frame) is continuously displayed for a predetermined time, so that it is recognized as a still image so that the user can identify what image it is. 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 to the front so as not to overlap the central character, and stops when it reaches a position near the front of the screen (step 309).
[0029]
Note that the character, for example, stores a video of one rotation of the character divided into 24 patterns and stores them, and makes them appear to rotate by pasting them together frame by frame. An example of this is to display so as to make one round in about 1.5 seconds. Further, the display time of a still image at the beginning of character display can be set freely, but can be set as follows, for example. That is, the image data for moving images is once displayed after being read into the graphic memory 5 for drawing. However, since it takes time to read a plurality of pieces of image data, the reading time is the first still image. Is displayed, and the moving image is displayed by repeating the display sequentially after the reading is completed.
[0030]
That is, instead of simply continuing to display the still image of the first frame until a predetermined time elapses, the remaining 23 frames of data are developed in the graphic memory 5 using the display time of this still image. Like that. In this way, immediately after the function is switched, it is not necessary to expand 24 frames at a time, but only the first frame needs to be expanded, so that character display can be performed quickly. Thereafter, the second and subsequent frames are displayed at a certain time interval to display a moving image. Until the function is switched again, the moving image display is always performed at a fixed interval.
[0031]
Also, the function title that flows in front of the character display stops when it reaches the front of the screen, but the rotation display of the character and the flow display of the function title are processed in parallel so that they are performed simultaneously and overlap each other. It is displayed so as not to become.
[0032]
[3. Effects of the embodiment
According to the present embodiment as described above, the function title and the character representing the selected function are displayed in a moving image, so that the function selected by the user can be easily recognized, can be enjoyed visually, and is comfortable. Useful for creating a feeling of operation and the interior of the car. Further, since the function title and character are displayed as a still image at the beginning of display, the function can be easily confirmed when selected. In particular, by writing the moving image data in the graphic memory 5 using the still image display time, the first still image can be quickly displayed immediately after the function is switched. Even if it exists, display delay can be prevented.
[0033]
In addition, the function can be recognized by the meaning represented by the function title, and the function can be intuitively recognized by the character, so that the user can accurately recognize the function regardless of the viewing position, angle, video state, etc. Can be recognized. Furthermore, since the function title and the character display do not overlap each other, mistakes such as misidentification of the function are prevented.
[0034]

For example, the format of image data, the image processing method, and the like include all that can be used now or in the future. The display timing can be controlled for a predetermined time. For example, in the case of the character display shown in the above embodiment, the second frame and subsequent memories are expanded. You may set so that it may change from a still image display to a moving image display after detecting that it complete | finished. The display screen illustrated in the above embodiment is an example, and various display positions and sizes, deformation modes, and movement modes of characters and pictures can be applied.
[0035]
