Abstract

A vehicle-mounted display device includes an input unit, a foreground image acquisition unit, a brightness value calculation unit, a background image conversion unit, a combining unit, and a display unit. The foreground image acquisition unit acquires a foreground image including vehicle information. The brightness value calculation unit calculates a brightness value of a background image input from the input unit. The background image conversion unit converts the background image input from the input unit in accordance with the brightness value of the background image and color information of a theme color. The combining unit combines the foreground image and the background image converted by the background image conversion unit, and the display unit displays an image combined by the combining unit.

Claims

1. A vehicle-mounted display device comprising:

an input unit for inputting a background image;

a foreground image acquisition unit for acquiring a foreground image including vehicle information;

a brightness value calculation unit for calculating a brightness value of the input background image;

a background image conversion unit for converting the background image using the brightness value and color information of a theme color, the brightness value being calculated by the brightness value calculation unit;

a combining unit for combining the background image and the foreground image, the background image being converted by the background image conversion unit; and

a display unit for displaying an image combined by the combining unit.

2. The vehicle-mounted display device according to claim 1, wherein the background image conversion unit makes a color phase component of the background image identical to a color phase component of the theme color.

3. The vehicle-mounted display device according to claim 1, wherein the background image conversion unit specifies a color phase component of the background image to a color phase component closer to the color phase component of the background image within a predetermined range around a color phase component of the theme color.

4. The vehicle-mounted display device according to claim 2, wherein a color phase component of the converted background image is H of an HSV model.

5. The vehicle-mounted display device according to claim 3, wherein a color phase component of the converted background image is H of an HSV model.

6. The vehicle-mounted display device according to claim 2, wherein a color phase component of the converted background image is H of an HSL model.

7. The vehicle-mounted display device according to claim 3, wherein a color phase component of the converted background image is H of an HSL model.

8. The vehicle-mounted display device according to claim 2, wherein a color phase component of the converted background image is Cr of a YCrCb model.

9. The vehicle-mounted display device according to claim 3, wherein a color phase component of the converted background image is Cr of a YCrCb model.

10. The vehicle-mounted display device according to claim 1, wherein the background image conversion unit makes the brightness value of the background image identical to a brightness value of the converted background image.

11. The vehicle-mounted display device according to claim 1, further comprising:

a brightness value determination unit for comparing the brightness value of the background image with a threshold; and

a brightness value reduction unit for reducing the brightness value of the background image in accordance with a result of determination performed by the brightness value determination unit,

wherein the background image conversion unit converts the background image in which the brightness value is reduced.

12. The vehicle-mounted display device according to claim 1, further comprising a theme color acquisition unit for acquiring a theme color of a vehicle,

wherein the background image conversion unit converts the background image using the theme color acquired by the theme color acquisition unit.

14. A method for controlling the vehicle-mounted display device according to claim 11, wherein, when the background image is converted, a color phase component of the background image is made identical to a color phase component of the theme color.

15. A method for controlling the vehicle-mounted display device according to claim 11, wherein, when the background image is converted, a color phase component of the background image is made identical to a color phase component closer to the color phase component of the background image within a predetermined range around a color phase component of the theme color.

13. A method for controlling a vehicle-mounted display device, the method comprising the steps of:

inputting a background image;

acquiring a foreground image including vehicle information;

calculating a brightness value of the input background image;

converting the background image using the brightness value of the calculated background image and color information of a theme color;

combining the converted background image and the foreground image; and

displaying the combined image.
