A display device, a display system, and a mobile object. The display device includes an image forming unit through which image light exits, an imaging optical system having a reflection plane and configured to form an image by reflecting the image light on the reflection plane, and a housing accommodating the image forming unit and the imaging optical system. The housing has a transmissive area through which the image light reflected by the imaging optical system passes through, and an inclination of the reflection plane is changed to reduce a project area of the reflection plane. The project area is projected to outside of the housing through the transmissive area. The display system includes the display device, and a reflector configured to reflect the image light reflected by the imaging optical system. The mobile object includes the display system, and the reflector is a front windshield.

Camera control systems and methods for providing a dynamic view of the environment outside of a vehicle are presented. One or more cameras are configured to capture at least one view of the environment outside of the vehicle. Control circuitry detects at least one of the speed of the vehicle and the pitch angle of the vehicle (e.g., by using a speedometer and inclinometer). The control circuitry selects a view angle based on the at least one of the speed of the vehicle and the pitch angle of the vehicle. The control circuitry then displays, based on an output of the at least one camera, a view of the environment outside of the vehicle from the selected view angle on a display of the vehicle.

There is disclosed a system for generating and displaying augmented reality content on a display that incorporates movement both internally and externally to the display and takes into account the perspective of a viewer so that three-dimensional content may properly perspective shift based upon movement of the viewer or viewers.

Provided is a projection type display device capable of performing display of information according to a driver's desire. An HUD includes light sources; a light modulation element that spatially modulates light emitted from the light sources on the basis of projection image data; a projection unit that projects image light that is spatially modulated by the light modulation element onto a projection surface that is a part of a windshield 1 mounted in an automobile; a designation information acquisition unit that acquires designation information for designating at least one of a maximum number of pieces of content included in the projection image data, display sizes of the pieces of content, or arrangement layouts of the pieces of content on the basis of information input through an operation unit; and an image information generation unit that generates the projection image data on the basis of the designation information acquired.

A drive assistance system receives predicted future actions taken by each of a vehicle and another vehicle, based on vehicle information obtained by each of the vehicle and the other vehicle, determines, based on the predicted future actions by the vehicle and the other vehicle, whether the future action by the other vehicle influences the future action by the vehicle; and transmits information causing display of the future action by the other vehicle having been determined to influence the future action by the vehicle, such that the future action by the other vehicle is caused to be displayed superimposed on a real view

First and second diffractive reflective elements form an optical path that guides a display light from a display unit toward a projection portion. The first diffractive reflective element is placed on the optical path to reflect the display light toward the projection portion by causing diffraction such that an incident angle and an emission angle of the display light are different from each other. The second diffractive reflective element is placed between the display unit and the first diffractive reflective element on the optical path to reflect the display light from the display unit toward the first diffractive reflective element by causing diffraction such that an incident angle and an emission angle of the display light are different from each other.

A multi-layer display system may include three, four, or more display panels/screens arranged in an overlapping manner, a backlight configured to provide light to the plurality of display screens, and a processing system. The processing system may be configured to display, on a first display screen of the plurality of display screens, a first image including a first gradient area, display, on a second display screen of the plurality of display screens, a second image including a second gradient area, and display, on a third display screen arranged in an overlapping manner between the first display screen and the second display screen, a third image including. The third image may include a third gradient area overlapping at least a portion of the first gradient area displayed on the first display screen and at least a portion of the second gradient area displayed on the second display screen.

An information display apparatus irradiates a transmissive reflection member with light for forming an image so as to make a virtual image of the image visible on the transmissive reflection member. The information display apparatus includes a memory, and a processor coupled to the memory and configured to control, upon a change in depth of a scene position at which to superimpose the virtual image, a degree of change in a part or an entirety of the virtual image to be displayed, differently from a degree of the change in depth.

A head-up display device projects a virtual image. The head-up display device includes a display, a first optical member, a second optical member, and an adjuster. The display outputs light that becomes a display image corresponding to the virtual image. The first optical member reflects the light incident from the display. The second optical member reflects or transmits the light reflected by the first optical member such that the virtual image is projected. The adjuster moves the first optical member to adjust a projection distance of the virtual image. The adjuster changes a distance between the first optical member and the second optical member and an inclination angle of the first optical member with respect to the display according to the projection distance of the virtual image.
