Abstract

A drop in visibility of display information is prevented while securing a clear view outside a vehicle. A display information extracting unit is configured to extract a particular portion from display information, which is displayed on a transparent display provided in a vehicle, based on a color-by-color pixel count of the display information. A display information output unit is configured to output to the transparent display the display information in which the particular portion extracted by the display information extracting unit has been changed in luminance.

Claims

1. A system, comprising:

a vehicle;

a transparent display provided in a vehicle; and

a processor that is configured to

extract a particular portion from display information, which is displayed on the transparent display, based on a color-by-color pixel count of the display information,

output to the transparent display the display information in which the particular portion extracted has been changed in luminance,

count a number of pixels of the display information for each color separately, and to extract a portion of one color that has the highest pixel count as the background portion,

store display'"'"'s information about a display, to which the display information is output, layer information that indicates layers of the display information to be output to the display, and color conversion regulation information that lays down a color conversion regulation for each of the layers, in association with one another,

the processor is configured to convert colors of the layers by referring to the color conversion regulation information, and to composite the layers of the display information to be output to the display, by referring to the layer information,

extract the background portion of the display information as a background layer when no background layer is included in the display information output from a navigation device.

2. A system according to claim 1, wherein the processor is configured to change the luminance of the background portion.

3. A system according to claim 2, wherein the processor is configured to lower the luminance of the background portion when a luminance of a color of the display information that has a highest pixel count is higher than a given threshold.

4. A system according to claim 3, wherein the processor is configured to raise luminances of other colors of the display information than the color that has a highest pixel count when an average luminance value of the other colors than the color that has the highest pixel count is lower than a given threshold.

5. A system according to claim 2, wherein the processor is configured to hold back from changing a luminance of a given color of the background portion when the display information is a specific type of information.

6. A system according to claim 5, wherein the specific type of information comprises information that warns a user or that calls a user'"'"'s attention.

7. A display control method for a display control device a system, comprising:

providing a vehicle;

mounting a transparent display in the vehicle;

extracting a particular portion from display information, which is displayed on the transparent display, based on a color-by-color pixel count of the display information;

outputting to the transparent display the display information in which the particular portion extracted has been changed in luminance;

counting a number of pixels of the display information for each color separately, and to extract a portion of one color that has the highest pixel count as the background portion;

storing display'"'"'s information about a display, to which the display information is output, layer information that indicates layers of the display information to be output to the display, and color conversion regulation information that lays down a color conversion regulation for each of the layers, in association with one another;

converting colors of the layers by referring to the color conversion regulation information, and to composite the layers of the display information to be output to the display, by referring to the layer information; and

extracting the background portion of the display information as a background layer when no background layer is included in the display information output from a navigation device.
