  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The vehicle display device 100 includes an image processing unit 11 and a control unit 21.

  The image processing unit 11 is composed of a graphic control microcomputer. A video signal from the portable information device 200 is input to the image processing unit 11. The control unit 21 includes a vehicle information processing microcomputer. Vehicle information from the vehicle ECU group 300 that controls the engine and the transmission is input to the control unit 21. The control unit 21 is connected to the portable information device 200, and a control signal of the portable information device 200 is input / output.

The control unit 21 is connected to a ROM 22 for storing a program, a RAM 23 for a processing work area, and an EEPROM 24 for storing an accumulated mileage of the vehicle and a color adjustment set value. A predetermined process is executed in accordance with the stored program.
In the predetermined processing, the remaining fuel, the accumulated distance of the vehicle, the vehicle speed, and the engine speed are calculated based on the vehicle information from the vehicle ECU group 300, and the display vehicle information is transmitted to the image processing unit 11. The control unit 21 transmits interrupt display information to the image processing unit 11 when the remaining fuel is reduced.

The control unit 21 transmits the RGB control information stored in the ROM 22 or the EEPROM 24 to the image processing unit 11. The RGB control information indicates the RGB color limit values and correction formulas for the first display area of the display 15 and the RGB color limit values and correction formulas for the second display area.
The control unit 21 uses various input information from the connected portable information device 200 (for example, terminal model information, remaining battery amount, GPS information, operation information of the portable information device 200 by the user, and the like). For example, when the remaining battery is low, the charging function is enabled, the user operation information is reflected in the operation of the display unit 15 and the meter unit, and the like.

  The image processing unit 11 is connected to a ROM 12 for storing a program, a RAM 13 for a work area for processing, and a VRAM 14 for a work area for image data to be displayed on the display 15. The RAM 13 serves as a work area for the process and the VRAM 14 Is used as a display image work area, and image processing is executed in accordance with the drawing program and component image stored in the ROM 12.

The image processing unit 11 displays each vehicle information in the first display area 15 a based on the display vehicle information transmitted from the control unit 21.
When the portable information device 200 is connected, the image processing unit 11 displays the video or image input from the morphological information device 200 in the second display area 15b.
Based on the interrupt display information transmitted from the control unit 21, the image processing unit 11 performs an interrupt display such as a remaining fuel warning in the second display area of the display unit 15.

  Based on the RGB control information transmitted from the control unit 21, the image processing unit 11 performs a correction process on the RGB values of the display images displayed in the first display area 15 a and the second display area 15 b. The display image has a value of 8 bits (0 to 255) in R (red), G (green), and B (blue) for the display resolution (for example, 800 × 480 pixels) of the display unit 15, so-called RGB format. It consists of pixel data.

  The system configuration is not limited to this embodiment. For example, a microcomputer in which the image processing unit 11 and the control unit 21 are integrated may be used. In the present embodiment, the processing performed by the control unit 21 may be performed by the image processing unit 11, or the processing performed by the image processing unit 11 may be performed by the control unit 21.

  The display screen of the display device 15 includes a first display area 15a for displaying vehicle system information and a second display area 15b for displaying information from an external device. The first display area 15a includes a remaining fuel meter that displays the remaining fuel, a running accumulator, an engine tachometer, a red zone that indicates the danger, and a speed display. The second display area 15b includes an image display of an external device displayed from the external device. Since the second display area 15b depends on the display of the external device, navigation display is performed in the present embodiment, but the present invention is not limited to this.

  For example, a jacket display of audio information is performed in the second display area 15b. If the displayed image contains a bright red or bright orange color, there is a possibility that it may be mistaken as if urgent interrupt warning information is displayed there. Therefore, in the second display area 15b, the gray scale image is first displayed by the chromaticity step control means included in the image processing unit 11, and the color image is gradually displayed. Also, the RGB value of the display information in the second display area 15b is changed by the color limiting means so as not to exceed the color limit value stored in the volatile memory in order to avoid the external device information being displayed too vividly. To display.

  When the warning information is generated, an interrupt display is performed on the second display area 15b having a low priority. At that time, the chromaticity level control means and the color restriction means are not used for the interrupted warning information.

  FIG. 5 is a chart showing a state in which the image processing unit 11 controls the chromaticity information of the image. The image processing unit 11 gradually increases the chromaticity information after the deviation scale image is displayed. If the chromaticity is higher than the warning information, the image processing unit 11 performs RGB of the display information in the second display area 15b by the color limiting unit. Control the numerical value below the color limit value. In the present embodiment, although it is a constant change, it may be a curvilinear change or a step change.

  Next, the flow of processing in the present embodiment will be described with reference to FIG. First, based on the vehicle display information transmitted from the control unit 21, an image to be displayed in the first display area 15 a is generated using a drawing program or a component image stored in the ROM 12. Next, a process for determining whether or not there is an interrupt display request is performed. If there is an interrupt display, an image to be displayed in the second display area 15b is displayed based on the interrupt display information transmitted from the control unit 21. It is generated using a drawing program or a component image stored in the ROM 12.

  When there is no interrupt display, an image to be displayed in the second display area 15b is generated based on the video signal transmitted from the portable information device 200. Further, based on the RGB control information transmitted from the control unit 21, correction processing is executed on the RGB values. The correction processing in this embodiment is performed by the chromaticity level control means and the color restriction means. For example, when the setting time of the chromaticity step control means is 2 seconds and the color limit value is 80%, the image of the portable information device 200 displayed in the second display area 15b is 2 from the grayscale image with chromaticity 0. A process of gradually increasing the chromaticity to 80% of the chromaticity that can be expressed by the display unit 15 over a second is executed. In addition, the RGB values are individually corrected in consideration of the color balance. Alternatively, chromaticity scaling may be performed with the color limit value set to the maximum value. Further, instead of the limit value, a correction formula (for example, simply reducing the R value to 1/2) may be used.

  Next, an image to be displayed on the display 15 is generated based on the image to be displayed on the first display area 15a and the image to be displayed on the second display area 15b. Finally, a process for displaying the display image on the display 15 is executed.

  According to this embodiment, the interrupt information not including the warning information is gradually changed from the gray scale image to the color image, so that the display can be easily distinguished from the interrupt information including the warning information.
