An information display apparatus emits an image forming light beam to a transmissive reflection member and makes a virtual image visible through the reflection member. The information display apparatus is configured to display the virtual image so that a difference between a convergence angle when viewing the virtual image through the reflection member and a convergence angle when viewing a real object through the reflection member is less than or equal to 1 degree.

A transparent display for a vehicle that includes a self-emissive display with an electronically adjustable brightness and a masking display with an electronically adjustable absorption. The masking display is arranged back-to-back with the self-emissive display. At least one light sensor that is arranged in proximity to the masking display. A display controller is connected to the self-emissive display, to the masking display and to the at least one light sensor. The display controller is operative to adapt an absorption of the masking display in response to a signal of the at least one light sensor.

A vehicle rear monitoring system includes a camera that captures an image of an area to a rear of a vehicle, and a processing unit that processes the image captured by the camera. The processing unit creates a first vehicle rear image that is displayed in a first display area that is a portion of a display area of a display device, when traveling forward, and creates a second vehicle rear image that is displayed in a second display area that is within the display area of the display device and that is an area that includes the first display area and is larger than the first display area, when traveling backward.

Disclosed are methods and systems for adjusting pixels of a display screen in a vehicle. The methods and systems may include determining a position of the sun relative to a position of the vehicle, determining potential incident light rays from the sun striking the display screen based on the position of the sun, and adjusting one or more characteristics of one or more of the pixels of the display screen based on the potential incident light rays.

A vehicle display device includes a conversion block that converts, based on correction data stored in a memory, an imaging pixel value in a camera image acquired by an outside camera into a correction pixel value in accordance with outside brightness detected by a brightness sensor, and a display control block that controls a display pixel value of the display image formed by the head-up display in correspondence with the correction pixel value converted from the imaging pixel value by the conversion block.

A vehicle display device includes a conversion block that converts, based on correction data stored in a memory, an imaging pixel value of a specific pixel portion captured on a near side of at least one of a vanishing point or a horizon line in a camera image acquired by an outside camera into a correction pixel value in accordance with outside brightness detected by a brightness sensor, and a display control block that controls a virtual image display luminance of a display image displayed by a head-up display in correspondence with the correction pixel value converted from the imaging pixel value by the conversion block.

The present disclosure provides a head up display device and system, relating to the field of display technology. The head up display device includes: a first display image generator, configured to generate a first linearly polarized light containing a first image; a second display image generator configured to generate a second linearly polarized light containing a second image; wherein the polarization direction of the first linearly polarized light is perpendicular to the polarization direction of the second linearly polarized light; a first polarizing beam splitter configured to combine the first linearly polarized light and the second linearly polarized light; and an optical component containing a plurality of reflective imaging elements, wherein the optical component is configured to reflect the first image and the second image into a user's eye.

A method for pairing a key fob with a control unit is provided. The key fob executes an ID authenticated key agreement protocol with a pairing device based on a key fob identification to authenticate one another and to generate a first encryption key. The pairing device encrypts a control unit identification using the first encryption key. The key fob receives the encrypted control unit identification transmitted from the pairing device. The key fob then executes an ID authenticated key agreement protocol with the control unit based on the control unit identification to authenticate one another and to generate a second encryption key. The key fob then receives an operational key transmitted from the control unit that is encrypted with the second encryption key.

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.

Modifying vehicle display parameters using operator gaze, including: detecting a gaze of an operator of a vehicle; and modifying one or more parameters of a display based on the gaze of the operator.
