  Embodiments of the present invention will be described below with reference to the drawings. Here, a vehicle display device is taken as an example. In the drawings referred to below, the same or corresponding parts are denoted by the same reference numerals.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram of a display device (vehicle display device) according to Embodiment 1 of the present invention. In FIG. 1, a sensor 10 is various sensors that detect the state of a vehicle and output instrument information, such as a vehicle speed sensor 11, a water temperature sensor 12, a rotation speed sensor 13, and a fuel amount sensor 14, for example. Hereinafter, an image for presenting the state of the vehicle to the driver based on the instrument information is referred to as an instrument image.

  The navigation system 20 is a device that performs route guidance based on a GPS (Global Positioning System) signal or the like, and outputs a guidance image (also referred to as a navigation image). The camera 30 is a device that captures the outside of the vehicle and outputs a captured image (also referred to as a camera image). Here, the navigation system 20 and the camera 30 are shown as examples of devices that output images, and the present invention is not limited to these devices.

  Hereinafter, an image of a device such as the navigation system 20 or the camera 30 is referred to as a device image. Since the device images of the navigation system 20 and the camera 30 do not always need to be displayed by the user, the devices are operated to output images when the user needs to display them. Shall.

  The instrument information output from the sensor 10 is input to the instrument image generation unit 41 of the display image generator 40. The instrument image generation unit 41 generates an instrument image based on the input instrument information. Here, the instrument image is an image for presenting the vehicle state to the driver as described above, such as a speedometer image, an engine tachometer image, and a warning image for notifying the driver of the vehicle abnormality. It is an image.

  The instrument image generation unit 41 outputs the generated instrument image to the image composition unit 42. In addition, device images output by devices such as the navigation system 20 and the camera 30 are input to the image composition unit 42. The image synthesis unit 42 synthesizes the input instrument image and the device image, generates a display image to be displayed on the screen 51 of the display device 50, and outputs it. The display 50 displays the input display image on a screen 51 such as a liquid crystal panel.

  The image composition unit 42 detects the change in the type and number of instrument images and device images that are input in the composition of the display image, determines the display position of each input image as an opportunity, and the screen configuration of the display image To decide. Regarding the determination of the screen configuration, for example, the screen configuration pattern corresponding to the type and number of images to be displayed simultaneously is stored in advance in the storage device, and the screen configuration pattern is specified using the type and number of images to be displayed as an index. What should I do?

  The images output from the navigation system 20 and the camera 30 to the display image generator 40 and the images output from the display image generator 40 to the display 50 are general such as an image based on the RGB color model or the YUV color model. The present invention is not limited to the image technology including the format of the image data. For example, it may be image data compressed by an image compression technique.

  FIG. 2 shows a state in which only the instrument image is displayed on the screen 51 of the display 50 (FIG. 2A), and the driver performs an operation of displaying the navigation image on the display 50 to display the instrument image and the navigation image. It is a display example of a screen in a state of being displayed (FIG. 2B). In FIG. 2, the warning area displays 190a and 190b are indicated by broken lines for convenience in order to make the description of the position of the warning area clear and easy to explain, and are not actually displayed. Here, the warning area is an area for displaying a warning image that indicates to the driver that there is no abnormality because the light is normally turned off and that is turned on when there is an abnormality to give a warning to the driver.

  In FIG. 2A, the display 50 displays a fuel gauge 210, a speedometer 220, an engine tachometer 240, and a water temperature gauge 250 on a screen 51. In FIG. 2B, the display device 50 displays a navigation image 260 on the screen 51, and the warning area display 190 b is rearranged below the navigation image 260.

  2A and 2B, the warning area displays 190a and 190b are not actually displayed. For example, when the display changes from FIG. 2A to FIG. It is difficult for the driver to recognize the position of the warning area (the position of the warning area display 190b) in FIG. 2B, and when the warning image is displayed, the driver overlooks this, or the driver confirms the warning. There is a problem that driving is distracted by looking for the display position of the warning image and moving the line of sight on the screen 51.

  In the vehicular display device of this embodiment, when the arrangement of the warning area on the screen 51 is changed, the display image generator 40 generates a display image including the warning area image (display area image) and displays the display 50. The warning area image is displayed on the screen 51. Here, the warning area image is an image for presenting the position of the warning area to the driver.

  FIG. 3 shows an example of the warning area image 200 (200a, 200b) in this embodiment. The warning area image 200 of this embodiment is a frame line image surrounding the warning area. The warning area image 200a is an image showing the warning area display 190a of FIG. 2 (a) to the driver, and the warning area image 200b is an image showing the warning area display 190b of FIG. 2 (b) to the driver. The border color may be a specific color that is easily recognized by the driver. Further, it may be set by the user. Note that FIG. 3 also shows a warning image displayed in the warning area for easy understanding.

  The image composition unit 42 of the display image generator 40 requests the instrument image generation unit 41 for a warning area image when moving the position of the warning area in the generation of the display image. The instrument image generation unit 41 generates a warning area image 200 and inputs it to the image composition unit 42, and the image composition unit 42 that has received the image generates a display image including the warning area image.

  When the warning area image differs depending on the position of the warning area on the screen 51 as in the warning area image 200 shown in FIG. 3, a warning area image having a necessary pattern is defined in advance, and an instrument image is generated from the image synthesis unit 42. The warning area image to be used may be designated for the part 41. Alternatively, the warning area image can be designated by coordinates on the screen 51. It is also possible to generate a warning area image by the image composition unit 42. Here, it is assumed that the image composition unit 42 designates and requests the warning area image 200a or 200b shown in FIG.

  The instrument image generation unit 41 continues the output of the warning area image 200 to the image composition unit 42 until a predetermined time elapses, and stops outputting after the elapse of time. At this time, the time when the output of the warning area image 200 is started is set to 0, and the luminance of the warning area image 200 is displayed as shown in FIG. 4 using predetermined times T1 and T2 (0 ≦ T1 ≦ T2). The luminance may be gradually changed from 0 at the start to 0. Such a canceling method can be realized by simple processing, and the warning area image 200 gradually becomes dark, so that it is easy to remain in the driver's impression, and effectively presents to the driver that the display content has changed. Can do.

  Here, the output of the warning area image 200 is stopped after a predetermined time has elapsed. For example, an operation indicating that the driver has confirmed is performed and this information is input to the display screen generation unit 40. You may make it cancel a display by another opportunity, such as triggered by this.

  FIG. 5 is a flow of display image composition processing of the image composition unit 42 in this embodiment. The image composition unit 42 first receives an image input (instrument image, warning area image, device image) to the image composition unit 42 in S10. Here, the warning area image and the device image are received when there is an input to the image composition unit 42.

  Next, it is determined whether or not there is a change in the presence or absence of input of the device image (S20). If there is no change in the presence or absence of input of the device image, the image composition unit 42 generates a display image using each received image (S30). The generated display image is output to the display device 50 (S40).

  If there is a change in the presence / absence of device image input in S20, the image composition unit 42 selects one configuration from predetermined display image configurations based on the input image, and displays a warning area on the screen 51. It is determined whether or not the arrangement change is necessary (S50). For example, when a new image is input from the navigation system 30 from the state shown in FIG. 2A, the arrangement of the warning area needs to be changed in order to obtain the configuration shown in FIG. When the layout change is unnecessary, the process of S30 is performed, a display image is generated using the received image, and the display image 50 is output by the process of S40.

  If it is determined in S50 that the warning area needs to be changed, the warning area image (warning area image 200a or 200b) to be displayed when the arrangement is changed is selected (S60), and the selected warning area image is displayed as the instrument image generation unit 41. (S70). Then, a warning area image is received from the instrument image generation unit 41 (S80), the process of S30 is performed using each received image, a display image is generated, and the display image 50 is output by the process of S40.

  FIG. 6 is a flow of warning area image generation processing of the instrument image generation unit 41 in this embodiment. Here, the brightness of the warning area image 200 is not gradually lowered, but the output is stopped after a lapse of a specified time.

  The instrument image generation unit 41 first checks whether or not there is a request for the warning area image 200 from the image composition unit 42 (S110). If there is no request, there is no particular processing. If there is a request, the requested warning area image 200 is generated (S120), and the generated warning area image 200 is output to the image composition unit 42 (S130). The output of the warning area image 200 to the image composition unit 42 continues until a predetermined time elapses. Therefore, the instrument image generation unit 41 determines whether or not the specified time has elapsed after starting the output of the warning area image 200 (S140). When the specified time has elapsed, the output of the warning area image 200 is stopped (S150).

  In addition, the process which produces | generates an instrument image separately from the process of FIG. 6, and outputs it to the image synthetic | combination part 42 shall be performed regularly.

  About the processing flow shown in FIG. 5 and FIG. 6, as long as it becomes an equivalent processing result, each processing content and procedure may differ.

  Next, the operation of the vehicular display device according to this embodiment will be described using a case where a navigation image is displayed as an example. The instrument image generation unit 41 of the display image generator 40 generates an instrument image of each instrument based on the instrument information input from the sensor 10 and inputs the instrument image to the image composition unit 42. The image composition unit 42 generates a display image using the instrument image and the device image from the instrument image generation unit 41 and outputs the display image to the display 50. The display device 50 displays the input display image on the screen 51. This process is repeatedly performed to update the display image presented to the driver.

  If the driver is not performing an operation for displaying a navigation image, a camera image, or the like on the display device 50, the display device 50 displays an instrument image on the screen 51 as shown in FIG. Here, when the driver performs an operation of displaying a navigation image, the navigation image is input from the navigation system 20 to the display image generator 40. The display image generator 40 to which the navigation image is input inputs it to the image composition unit 42. The image composition unit 42 to which the navigation image is input performs processing according to the flow shown in FIG.

  The image compositing unit 42 that has received the input image in S10 detects that a new device image (navigation image) has been input (S20), and the warning area is the position of the warning area display 190a shown in FIG. From this, it is determined that the layout needs to be changed to the warning area display 190b shown in FIG. 2A (S50). Then, the warning area image 200b is selected (S60), the warning area image 200b is requested from the instrument image generating section 41 (S70), the warning area image 200b is received from the instrument image generating section 41 (S80), and displayed. An image is generated (S30), and the generated display image is output to the display device 50 (S40).

  Further, the processing in the instrument image generation unit 41 that has requested the warning area image 200b from the image synthesis unit 42 is performed according to the flow shown in FIG. It is detected that the warning area image 200b is requested from the image composition unit 42 (S110), and the warning area image 200b is generated (S120). Then, the generated warning area image 200b is output to the image composition unit 42 (S130). The output of the warning area image 200b to the image composition unit 42 is stopped after a predetermined time (S140) is continued (S150).
