A display device includes a projection device RP that projects a notification pattern on a region in the vicinity of a vehicle CAR, an imaging device RC that images the region in the vicinity of the vehicle, and an object detection device OS capable of detecting an object (third party) present in a region which cannot be imaged by the imaging device RC. When the object detection device OS detects the object, the projection device RP projects the notification pattern in a form different from the notification in a normal state, so that the third party can visually recognize the notification pattern. The imaging device RC images a region including a region on which the notification pattern is projected, and displays, on a monitor MO visually checkable by the occupant, a captured image of the notification pattern projected in the form different from the notification pattern in the normal state.

Display device for vehicle

A vehicle drawing device draws a figure on a road surface with a light. When a luminance of the figure is assumed as a road surface drawing luminance, and a luminance in a surrounding environment of a driving vehicle is assumed as a background luminance, the light is irradiated such that a luminance contrast calculated by the road surface drawing luminance and the background luminance is 0.2 or more, and an angle formed by an inclination direction at a tip end of the figure with respect to a light irradiation direction is less than 120 degrees.

Vehicle drawing device

A projected display with improved visibility and understandability of a vehicle behavior. A vehicle projection device includes a projector that forms a projected image on a road surface; and a control unit. The control unit causes the projector to perform flashing projection of the projected image in a first period from start of projection, and causes the projector to perform sequential projection of the projected image in response to transition from the first period to a second period.

Vehicle projection device

A vehicle drawing device draws a sign on a road surface with amber-colored light. When a luminance of the sign is assumed as a road surface drawing luminance, and a luminance in a surrounding environment of a driving vehicle is assumed as a background luminance, the amber-colored light is irradiated such that a luminance contrast calculated by the road surface drawing luminance and the background luminance is 0.2 or more.

A head-up display device is provided in a vehicle together with a headlamp. The head-up display device includes a light source, a control unit, and a projection unit. The light source emits white light whose correlated color temperature is changeable. The control unit adjusts the correlated color temperature of the white light emitted from the light source. The projection unit forms image light by the white light emitted from the light source. The projection unit projects the image light onto a projection target member disposed in front of a driver of the vehicle, thereby displaying a virtual image superimposed on a landscape for the driver. The control unit adjusts the correlated color temperature of the white light emitted from the light source in accordance with a correlated color temperature of irradiation light emitted from the headlamp.

Head-up display device and head-up display system

A vehicle lamp includes a light source unit for road surface drawing capable of forming a light source image longer in an upper and lower direction than a left and right direction of the lamp and a projection lens through which light forming the light source image is transmitted and which projects a predetermined light distribution pattern on a road surface. A light emitting surface or a light transmitting surface of the light source unit is disposed in a vicinity of a rear focal point of the projection lens. The light emitting surface or the light transmitting surface is inclined with respect to an upper and lower direction orthogonal to an optical axis of the projection lens.
