An image display device includes a light source, a scanner, a screen, a virtual image optical system and a screen incident angle correcting optical system. The light source emits laser light. The scanner scans the laser light. An image is formed on the screen by the scanned laser light. The virtual image optical system generates a virtual image of the image by the laser light having transmitted through the screen. The screen incident angle correcting optical system orients the scanned laser light toward the screen. The scanner performs at least first scanning and second scanning that has a scanning direction different from a scanning direction of the first scanning. The screen includes a lenticular lens having a lens pitch in a direction parallel to the first scanning. The lens pitch of the lenticular lens is larger than a beam diameter of the laser light near a light receiving surface of the screen.

The objective of the present invention is to provide a heads-up display device able to efficiently orient image light towards a viewer by means of a simple configuration. The heads-up display device is provided with: a projection unit that emits projection light depicting a display image; a first reflection unit and second reflection unit that reflect the projection light exiting the projection unit towards a transmissive screen; and the transmissive screen that outputs image light towards an observer by transmitting/scattering the projection light. By adjusting the angle of the light axis of the projection light entering the transmissive screen by rotating the first reflection unit and second reflection unit, the angle of the image light exiting the transmissive screen is adjusted.

A vehicle display device includes: a display; a vehicle information image generator; an external image obtaining device; a display controller that displays the vehicle information image and the external image on the display; and an external image display determination device that determines whether the display controller is going to display the not displayed external image. When the display controller is going to display the not displayed external image, the display controller displays the external image, which the display controller is going to display, on the display with gradually increasing brightness of the external image from the brightness that is lower by a predetermined amount than original brightness to predetermined brightness that is determined based on the original brightness.

A vehicular display apparatus is provided on a vehicular instrument panel and provides a display for a vehicular crew. The apparatus includes: a half mirror that transmits light from a front of a vehicle to a back of the vehicle and reflects light from a direction intersecting with a front-back direction of the vehicle to the back of the vehicle, a decorative member provided to one side of a side of the front of the vehicle and a side of the intersecting direction, a light emitting member that irradiates the decorative member with light, and a liquid crystal display that is provided to the other side and projects an image toward the half mirror. The decorative member is arranged so as to provide a display superposed on the image projected by the liquid crystal display when visually recognized from a front side.

A display device includes an image display device that includes an image display surface that emits light polarized in one direction and displays an image; and a superimposing display device that includes a transparent light guide plate that is provided overlapping the image display surface, transmits the light emitted from the image display device, and also has grooves constituting a pattern formed thereon, includes a light source that irradiates an end surface of the transparent light guide plate with light, and is switched between display and non-display of the pattern based on lighting and non-lighting of the light source. A polarization direction of the image display device and an extending direction of the grooves intersect at an angle range of 75 to 105. Accordingly, the display device can ensure proper visibility.

Various aspects of a system and method to provide driving assistance are disclosed herein. The system comprises one or more circuits in an electronic control unit used in a vehicle configured to detect one or more actions associated with the vehicle based on one or more signals generated by one or more sensors embedded in the vehicle. The electronic control unit may be further configured to control the activation of an imaging device located on the vehicle at an opposite side of a driver of the vehicle, based on the detected one or more actions. The imaging device is operable to capture one or more images in a forward-facing direction of the vehicle.

This display device is provided with a display unit, a beam splitter, and a first mirror. The display unit emits a first image and a second image. The beam splitter has, incident thereon, the first image and the second image which are emitted from the display unit. The beam splitter transmits the incident first image and reflects the incident second image to project the first image and the second image on a display medium. The first mirror has, incident thereon, the first image which has been transmitted through the beam splitter. The first mirror reflects the incident first image to project the first image on the display medium.

Systems and methods for enhanced emergency vehicle warnings via Augmented Reality (AR) are provided. An example system may obtain a wireless communication signal indicating a position of an emergency vehicle, determine a field of view of an occupant of the vehicle associated with an AR viewer, and based upon a comparison of the position of the emergency vehicle and the field of view, present an alert via the AR viewer.

This display device is provided with a display unit and a control unit. The display unit projects and reflects, onto a light-transmitting display medium, light expressing an image, to allow the image to be viewed, as a virtual image, by a user. The control unit performs first stereoscopic display processing for causing light respectively expressing a left-eye image and a right-eye image of an object to be displayed, to be projected in the display unit. As a result of this processing, the object to be displayed can be stereoscopically viewed in a three-dimensional image space by the user.

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.
