The block diagram which shows the structure of embodiment of this invention. The figure which shows the example of the display transition in embodiment same as the above.

  Embodiments to which the present invention is applied will be described below with reference to the accompanying drawings.

  An example in which the vehicle display device of the present invention is applied to a vehicle instrument mounted on a vehicle will be described. As shown in FIG. 1, the vehicle meter includes a storage unit 1, a drawing unit 2 provided with a still image processing unit 21 and a moving image processing unit 22, a control unit 3, and a display unit 4.

  The storage unit 1 can be a non-volatile storage medium, stores component data such as still images and moving images, and allows the drawing unit 2 to read out the component data based on a control signal from the control unit 3.

The drawing unit 2 is a circuit that performs drawing calculation processing. The drawing unit 2 generates still image display data based on the component data stored in the storage unit 1. The drawing unit 2 stores the component data stored in the storage unit 1. A moving image processing unit 22 that generates moving image display data based on the image data and a combining processing unit 23 that combines the still image display data and the moving image display data so as to overlap each other are provided. The display unit 4 can be driven based on the combined display data combined by the combining processing unit 23 .

  The still image processing unit 21 reads out still image data (component data) stored in the storage unit 1 based on a control signal from the control unit 3 and displays a display position, a display timing, etc. in an image displayed on the display unit 4. The display data corresponding to the display unit 4 can be generated as the still image display data after adjustment.

  The still image processing unit 21 can also generate still image display data by combining a plurality of still image data. For example, the still image processing unit 21 generates still image display data in which a character image is superimposed on a background image. You can also. Note that, when it is not necessary to synthesize moving image display data, which will be described later, the display means 4 can be driven based on the still image display data.

  The moving image processing unit 22 reads the moving image data (component data) stored in the storage unit 1 based on the control signal from the control unit 3, and displays the display position, display timing, and enlargement / reduction in the image displayed on the display unit 4. Display data corresponding to the display means 4 can be generated as moving image display data. In this case, the storage unit 1 stores moving image data defined for the corresponding still image component data and the display transition method, and the moving image processing unit 22 updates the image based on the definition of the moving image data. A frame image for each period is generated as moving image display data. In this case, 60 frame images are generated per second and used as moving image display data.

  The composition processing unit 23 overwrites the display data of the predetermined area overlapping the display data for still image generated by the still image processing unit 21 and the display data for moving image generated by the moving image processing unit 22 in a predetermined order. Then, they are combined as if they are overlapped and generated as combined display data. Therefore, the drawing unit 2 capable of displaying a moving image can be configured with a simple configuration, because a portion having no display change is held as display data for still images, and a process of drawing again when the next frame image is generated can be omitted.

  For example, a microcomputer can be applied to the control means 3. Information from various sensors mounted on the vehicle is input, and various control processes are performed to generate and output a control signal for controlling the drawing means 2. . In this case, the control means 3 can input an operation signal from the start switch of the vehicle, and can control the drawing means 2 so as to produce a display effect when the vehicle is started or stopped, for example.

  As the display means 4, for example, a display panel using liquid crystal or organic EL can be applied, and display output can be performed based on a control signal from the control means 3. In this case, the display means 4 can display and output vehicle information such as a vehicle travel distance and an alarm state based on the image information.

  In addition, the control means 3 can perform the display effect with a moving image by the image display of the display means 4 at the time of vehicle starting as mentioned above, and as shown in FIG. An example of performing this will be described.

  The control means 3 uses the moving picture processing unit 22 to generate first moving image display data A for changing in a predetermined pattern on the basis of the moving picture data stored in the storage means 1, and to the display means 4. Display. In this case, the first moving image display data A is generated for each frame so that the round image becomes a moving image that gradually increases.

In the storage means 1 , still image data (component data) of the same image as that at the end time of the first moving image display data A (final frame image of the moving image) is prepared. The still image display data B based on the image data and the first moving image display data at the end point are superimposed and displayed, and the still image display data is also displayed in the frame image of the next image update cycle. to continue. Note that the display timing of the still image display data is managed by the control means 2 , and the time from the starting point of the display effect is counted so as to start at the end point of the first moving image display data A. .

  Next, second moving image display data C to be changed in a pattern different from that of the first moving image display data A is generated, and an image based on the second moving image display data C is displayed on the display unit 4. Display.

Accordingly, when the first moving image display data A and the second moving image display data C are controlled to be continuously displayed, the display calculation is delayed between the moving image display data A and C. Even when the display data for moving images cannot be supplied to the composition processing unit 23, the display transitions as if continuously by keeping still image data (still image display data B) similar to this in the lower layer. An image like this can be output to the display means 4.

Further, at this time, the control means 1 superimposes the first moving image display data A and the previously prepared still image display data B before the end point of the first moving image display data A, and displays the combined display data. By controlling the drawing means 2 so as to generate D, even when the display data for moving images A and C are not generated unexpectedly due to the load state of the drawing means 2 or the like, the still image to be interpolated is displayed. Display can be prompted.

  Such a vehicular display device includes a storage unit 1 for storing image display component data including a still image and a moving image, and a still image for generating still image display data based on the component data stored in the storage unit 1. The processing unit 21, the moving image processing unit 22 that generates moving image display data based on the component data stored in the storage unit 1, and the still image display data and the moving image display data are combined so as to overlap each other. A display unit for a vehicle provided with a synthesis processing unit 23 and displaying the synthesized display data D synthesized by the synthesis processing unit 23 on the display unit 4. First moving image display data A for changing in a predetermined pattern and second moving image display data C for changing in a pattern different from the first moving image display data A In the subsequent generation, the drawing unit 2 uses the same still image data as the end point image of the first moving image display data A prepared in advance in the storage unit 1 or the start point image of the second moving image display data. The display unit 4 displays the composite display data D in which the same still image data is superimposed between the end point of the first moving image display data and the start point of the second moving image data.

  Therefore, even if a blank time occurs between the time when the display of the first video is stopped and the time when the display of the second video is started, a still image prepared in advance can be displayed. The problem of flickering display can be solved, and continuous video display can be provided. Moreover, since a state in which nothing is suddenly displayed can be suppressed, a display that does not give the vehicle user a sense of incongruity can be performed.

  The vehicle display device of the present invention has been described by way of example in the configuration of the embodiment described above, but the present invention is not limited to this, and the gist of the present invention is also achieved in other configurations. It goes without saying that various improvements and design changes can be made without departing from the scope.

  The present invention can be applied as, for example, a display device for a vehicle mounted on an automobile, a motorcycle, or a moving body including an agricultural machine or a construction machine.
