and display a line image extending toward a vehicle front side and having a base end in a vicinity of the vehicle by displaying the line image in a predetermined display region so as to appear in front of the vehicle, and perform emphasized display further toward a leading end side of the line image as the vehicle speed increases. ## Claims ### Claim 1 A vehicular display device comprising a processor, wherein the processor is configured to: acquire vehicle speed information regarding a speed of a vehicle; and display a line image extending toward a vehicle front side of the vehicle by displaying the line image in a predetermined display region so as to appear in front of the vehicle, the line image having a base end and a leading end, the base end being displayed to appear closer to the vehicle than the leading end such that the leading end appears to be farther in front of the vehicle than is the base end, the processor being configured to perform emphasized display of the line image further toward a leading end side of the line image than at a base end side of the line image as the vehicle speed increases. ### Claim 2 (depends on 1) The vehicular display device of claim 1, wherein the processor is configured to: acquire image information regarding a captured image of an area in front of the vehicle; and display the line image superimposed on the image of the area in front of the vehicle. ### Claim 3 (depends on 1) The vehicular display device of claim 1, wherein the processor is configured to display the line image superimposed on a scene ahead of the vehicle as seen by an occupant of the vehicle, by projecting the line image onto a windshield glass of the vehicle. ### Claim 4 (depends on 1) The vehicular display device of claim 1, wherein the processor is configured to perform display such that a length of the line image becomes longer as the vehicle speed increases. ### Claim 5 (depends on 4) The vehicular display device of claim 4, wherein the processor is configured to: display a pair of line images at positions corresponding to both width direction sides of the vehicle; and cause the line images to curve along a trajectory corresponding to a steering angle of the vehicle. ### Claim 6 (depends on 1) The vehicular display device of claim 1, wherein the processor is configured to perform the emphasized display such that the line image becomes a darker shade further toward the leading end side than at the base end side as the vehicle speed increases. ### Claim 7 (depends on 1) The vehicular display device of claim 1, wherein the processor is configured to perform the emphasized display by displaying the line image with a color saturation that is higher further toward the leading end side than at the base end side as the vehicle speed increases. ### Claim 8 (depends on 1) The vehicular display device of claim 1, wherein the processor is configured to perform the emphasized display such that the line image becomes thicker further toward the leading end side than at the base end side as the vehicle speed increases. ### Claim 9 (depends on 1) The vehicular display device of claim 1, wherein the processor is configured to display the line image as transparent. ### Claim 10 (depends on 1) A vehicular display system comprising: the vehicular display device of claim 1; and a display provided inside a vehicle cabin or outside the vehicle cabin and configured to display an image of an area in front of the vehicle and the line image. ### Claim 11 A vehicular display method comprising: acquiring vehicle speed information regarding a speed of a vehicle; and displaying a straight line-shaped mark extending in a direction of progress of the vehicle in front of the vehicle in a predetermined display region, the line-shaped mark having a base end and a leading end, the base end being displayed to appear closer to the vehicle than the leading end such that the leading end appears to be farther in front of the vehicle than is the base end, and performing emphasized display of the mark further toward a leading end side of the mark than at a base end side of the mark as the vehicle speed increases. ### Claim 12 A non-transitory storage medium storing a program executable by a computer to perform processing comprising: acquiring vehicle speed information regarding a speed of a vehicle; and displaying a straight line-shaped mark extending in a direction of progress of the vehicle in front of the vehicle in a predetermined display region, the line-shaped mark having a base end and a leading end, the base end being displayed to appear closer to the vehicle than the leading end such that the leading end appears to be farther in front of the vehicle than is the base end, and performing emphasized display of the mark further toward a leading end side of the mark than at a base end side of the mark as the vehicle speed increases.
