A luminance determining unit determines a luminance distribution of an exterior circumstantial image in a line-of-sight direction of a driver, and a luminance changing unit determines a bright region of this luminance distribution. Further, the luminance changing unit determines a luminance after the change in a peripheral region of this bright region. A virtual-image creating unit creates a virtual image based on the determined luminance, and a display processing unit displays this virtual image on a display unit. In this manner, since a display system displays the virtual image for use in increasing the luminance in periphery of the bright region, the feeling of the brightness for the driver can be moderated, and therefore, the visual recognition can be improved. That is, the display system can output the virtual image depending on the circumstances.

In at least some implementations, a vehicle has a windshield, a display transmitter having an output through which light is emitted onto at least part of the windshield, a sensor responsive to the one or both of a position of the windshield and the presence of a reflective surface associated with the windshield and onto which light is emitted from the display transmitter, and a controller. The controller is coupled to the display transmitter and is operable to change a mode of the display transmitter when the sensor does not detect the windshield in a home position or when the sensor does not detect the presence of the reflective surface.

A moving object including a display apparatus capable of performing highly visible display is provided. The moving object includes a display unit, an imaging unit, an arithmetic unit, and a control unit. The display unit has a function of displaying a display image. The imaging unit has a function of obtaining a first captured image including the display image and an external view overlapping with the display image. The arithmetic unit has a function of comparing a color of the display image and a color of the external view and correcting the color of the display image on the basis of a comparison result. The control unit has a function of controlling running of the moving object on the basis of the first captured image.

An automatic adjuster, when carrying out an AR superimposed display using a head-up display in a vehicle like a car, is able to perform eye position adjustment for the AR superimposition automatically without increasing a burden to a driver by controlling, according to the eye position information acquired from an eye position detector, in such a manner as to shift the driver's eye position in accordance with the reference position of the superimposed display, which serves as a position where the AR superimposition is performed appropriately, and by controlling a movable part of the driver's power seat the driver of the vehicle takes.

A head-up display 10 includes a MEMS mirror component 14 for displaying images and a combiner 12 for reflecting light from the MEMS mirror component 14 so that an observer observes reflected light as a virtual image and for transmitting ambient light. The combiner 12 includes a green light reflecting portion 17 for selectively reflecting mainly green light in a green light wavelength region, a red light reflecting portion 16 for selectively reflecting mainly red light in a red light wavelength region, and a blue light reflecting portion 18 for reflecting blue light in a blue light wavelength region. The light reflecting portions 16 to 18 are laid in layers. The green light reflecting portion 17 is arranged the closest to the MEMS mirror component 14.

A head-up display system and a vehicle system are provided. The head-up display system includes a display and a projection screen. The display is configured to display a first image. The projection screen is disposed adjacent to the display and is configured to let the first image to be projected thereon to form a second image. The display includes a first region adjacent to the projection screen and a second region away from the projection screen. The projection screen includes a third region adjacent to the display and a fourth region away from the display. When the display displays the first image, a brightness difference between the first region and the second region is greater than a brightness difference between the third region and the fourth region.

A head up display arrangement for a motor vehicle includes a picture generation unit having a plurality of light emitters each emitting blue light. A plurality of collimating optics receive the blue light from the light emitters and collimate the received blue light. At least one phosphor element receives the collimated blue light and converts the collimated blue light to diffuse white light. A liquid crystal display receives the diffuse white light and emits a light field dependent upon the diffuse white light. At least one mirror reflects the light field emitted by the liquid crystal display such that the reflected light field is again reflected by a windshield of the motor vehicle so as to be visible by a human driver of the motor vehicle as a virtual image.
