Further, when the display color of the content is other than white, the display control ECU sets the display luminance of the border of the content to a second predetermined value or more or sets the brightness of the border of the content to a third predetermined value or more. The display control unit, when the color of the display of the content is white, the display luminance of the border of the content is less than the second predetermined value or is larger than the second predetermined value fourth predetermined value, or the brightness of the border of the content is less than the third predetermined value. ## Claims ### Claim 1 A vehicle display control device, comprising: a display control unit configured to control a display of a content on a display device, wherein the content is superimposed on a background displayed in the display device, and at a position where a windshield glass of a vehicle is provided, change a display color of the content in accordance with a detail of the content to be displayed, wherein the display control unit is further configured to, in response to the display color being other than white and a color of the background of the content being same as the display color, set a display luminance of a border of the content to be a second predetermined value or higher, or a brightness of a color of the border of the content to be a third predetermined value or higher, and in response to the display color being white and the color of the background being white, set the display luminance of the border of the content to be less than the second predetermined value or to be a fourth predetermined value or higher, the fourth predetermined value being larger than the second predetermined value, or the brightness of the color of the border of the content to be less than the third predetermined value. ### Claim 2 (depends on 1) The vehicle display control device according to claim 1, wherein the display control unit is configured to cause the display device to display the content and the border of the content within a range including a range equal to or higher than a height of an eye of an occupant in the vehicle. ### Claim 3 (depends on 1) The vehicle display control device according to claim 1, wherein the display control unit is configured to cause an augmented reality glass or an augmented reality contact lens serving as the display device to display the content and the border of the content. ### Claim 4 (depends on 1) The vehicle display control device according to claim 1, wherein the display control unit is configured to cause a head-up display serving as the display device to display the content and the border of the content. ### Claim 5 (depends on 1) The vehicle display control device according to claim 1, wherein the display control unit is configured to select the display color of the content based on a degree of urgency. ### Claim 6 (depends on 5) The vehicle display control device according to claim 5, wherein the display control unit is configured to, in response to the degree of urgency being higher than a first predetermined degree, select the display color of the content to be red or orange, in response to the degree of urgency being equal to or higher than a second predetermined degree and lower than the first predetermined degree, select the display color of the content to be white, and in response to the degree of urgency being lower than the second predetermined degree, select the display color of the content to be blue or green. ### Claim 7 (depends on 1) The vehicle display control device according to claim 1, wherein the display control unit is configured to, in response to the display color being other than white and the color of the background of the content being same as the display color, set the display luminance of the border of the content to be the second predetermined value or higher, and in response to the display color being white and the color of the background being white, set the display luminance of the border of the content to be less than the second predetermined value or to be the fourth predetermined value or higher. ### Claim 8 (depends on 1) The vehicle display control device according to claim 1, wherein the display control unit is configured to, in response to the display color being other than white and the color of the background of the content being same as the display color, set the display luminance of the border of the content to be the second predetermined value or higher, and in response to the display color being white and the color of the background being white, set the brightness of the color of the border of the content to be less than the third predetermined value. ### Claim 9 (depends on 1) The vehicle display control device according to claim 1, wherein the display control unit is configured to, in response to the display color being other than white and the color of the background of the content being same as the display color, set the brightness of the color of the border of the content to be the third predetermined value or higher, and in response to the display color being white and the color of the background being white, set the display luminance of the border of the content to be less than the second predetermined value or to be the fourth predetermined value or higher. ### Claim 10 (depends on 1) The vehicle display control device according to claim 1, wherein the display control unit is configured to, in response to the display color being other than white and the color of the background of the content being same as the display color, set the brightness of the color of the border of the content to be the third predetermined value or higher, and in response to the display color being white and the color of the
