A situation determining section 11 determines a situation of a vehicle on the basis of driving information. A support image setting section 13 sets a support image in accordance with a determination result obtained by the situation determining section 11. A display control section 14 executes display control for displaying the support image set by the support image setting section on a window glass of the vehicle in accordance with the determination result obtained by the situation determining section 11. The support image enables a leading operation for a running route, an emphasis operation for a traffic sign or the like, a visibility lowering operation for an outside-vehicle object that may cause lowering of attentiveness of the driven vehicle, and the like, and driving support can be executed with a natural sense.

A vehicle includes a vehicle body having a cabin, a first seat and a second seat arranged in the cabin, a planar transparent member placed on a side surface of the cabin, and that separates an interior of the cabin and a vehicle exterior from each other, and a display device placed on the side surface of the cabin and arranged along the planar transparent member, the display device having a plurality of pixels. At least a part of the display device is placed on the side surface and between the first seat and the second seat.

To reduce discomfort of occupants caused by operation sound of a camera cooling system in a vehicle, a vehicle-mounted camera includes a camera cooler and a controller. The vehicle-mounted camera is installed inside of a windshield. The camera cooler cools the vehicle-mounted camera. The controller determines if the vehicle-mounted camera is in a high temperature state. If it is determined that the vehicle-mounted camera is in the high temperature state, the controller controls the camera cooler to operate. The controller controls an air conditioner to provide a sound generation process to generate concealing sound to conceal operation sound caused by the camera cooler when the air conditioner operates.

A window for a motor vehicle includes an inner glass pane, an outer glass pane, and a first display module having a first light source, a first light guide disposed between the inner glass pane and the outer glass pane and configured to receive light from the first light source, a second light source, and a second light guide disposed between the inner glass pane and the outer glass pane and configured to receive light from the second light source. When the first light source is activated a first signal is displayed through the first light guide, when the second light source is activated a second signal is displayed through the second light guide, and when the first light source and the second light source are activated a third signal is displayed through the first light guide and the second light guide.

The display includes a liquid-crystal panel, a heat-transfer member, and a light-diffusion structure. The liquid-crystal panel includes a display screen. The heat-transfer member is light-transmissive. The heat-transfer member is on an opposite side of the liquid-crystal panel from the display screen. The light-diffusion structure is between the liquid-crystal panel and the heat-transfer member.

A head-up display includes: a display device that emits image light; a mirror that reflects the image light; a mirror holder that supports the mirror and includes a rotational shaft; a bearing that rotatably supports the rotational shaft; and a pressing component that presses a portion of the rotational shaft. The rotational shaft includes an eccentric portion including an area in which a distance from a rotation center changes. The pressing component presses the eccentric portion.

The present disclosure provides a vehicle-mounted display system and a vehicle. The vehicle-mounted display system includes a transparent projection screen and a projector configured to project an image onto the transparent projection screen. A first polarizer is attached onto a lens of the projector, and a second polarizer is attached onto the transparent projection screen. The second polarizer has a polarization transmission direction crossing a polarization transmission direction of the first polarizer at such an angle as to enable a light beam from the projector and passing through the first polarizer and the second polarizer to be of an intensity smaller than an intensity of a light beam capable of being recognized by human eyes. The second polarizer has a polarization reflection direction perpendicular to its polarization transmission direction, so as to reflect a light component in the polarization reflection direction.

A display device displays information image related to an excavation work, in an ambient environment image in a view of a work area or an attachment viewed from a shovel, or in a field of view of an operator viewing the work area or the attachment from the shovel. The shovel may include the display device. A management device may include a display apparatus, a communication device which communicates with the shovel, and a remote control device operated by a user to remotely control the shovel via the communication device.

There is provided a head-up display for a vehicle having a window. The head-up display comprises a picture generating unit (410) and an optical system (420). The picture generating unit is arranged to output pictures. The optical system is arranged to receive the pictures output by the picture generating unit and project the pictures onto the window (430) of the vehicle to form a virtual image (450, 707) of each picture within a virtual image area (605). The picture generating unit is arranged to output pictures within a cropped picture area such that the virtual image area (605) has a corresponding cropped shape. FIG. 7 illustrates a perspective view of a three lanes road (501,502,503) onto which a virtual image (707) within a cropped virtual image area (605) is overlaid.

The visibility of the external scene from the inside of the transmissive transparent screen when the video image is not displayed and the visibility of the video image from the outside when the video image is displayed are satisfied. In a video image display system comprising a projection device 100 and a transmissive transparent screen 1 having a first surface and a second surface on the opposite side of the first surface, having a visible light transmittance of at least 5[%], and displaying video images projected from the projection device 100 installed on the first surface side, as video images visible to an observer on the second surface side, the following formula 1 is satisfied:
?1.5?ln(((B/A)/I)?G)?3.9Formula 1 in the formula 1, A is the projection area [m.sup.2] of the projection device 100, B is the luminous flux [lm] projected onto A by the projection device 100, I is the ambient illuminance [lx] at the side of the second surface, and G is the screen gain of the transparent screen 1.
