According to a vehicle display system, a mobile terminal apparatus includes: a primary-screen-view display section that displays an output screen-view generated with execution of an application on the mobile terminal apparatus as a primary screen-view; a conversion section that converts the primary screen-view into a secondary screen-view complying with a vehicle apparatus; a manipulation layer generation section that generates a manipulation layer to manipulate the application; a state layer generation section that generates a state layer indicating a state of the mobile terminal apparatus; and a transmission section that transmits the secondary screen-view, the manipulation layer, and the state layer to the vehicle apparatus. The vehicle apparatus includes a secondary-screen-view display section that displays the manipulation layer and the state layer on the vehicle apparatus itself together with the secondary screen-view.

The laser projection display device includes: a photo-sensor for detecting the quantity of laser light generated by the laser light source; and an image processing unit for processing a drive signal on the basis of the quantity of light of the detected laser light and supplying the processed drive signal to a driving unit for the laser light source. Right after the dimming, the image processing unit supplies the drive signal to the driving unit for the laser light source on the basis of the quantity of light of the detected laser light within a second execution cycle shorter than a first execution cycle which is the execution cycle used during the normal operation.

A head up display apparatus includes: an image display apparatus having a light source and a display element and forming an image; an image-light projecting means displaying a virtual image onto a forward part of a vehicle by projecting the image light emitted from the image display apparatus to be reflected on a windshield 3; and a point-of-view detecting system 6 sensing a point of view of the driver. In the head up display apparatus, the image-light projecting means includes a means generating illumination light entirely made of single-color visible light emitted to a face of the driver in a predetermined state of the vehicle.

A user interface device includes: an output device having an output region predefined around an output unit; an acquisition unit acquiring information about a user's gesture performed around the output region; and a controller determining an area of a shielded region which is shielded by the user's gesture in the output region based on the acquired information and controlling output of the output device.

A processing system comprises a first integrated circuit (IC) and a second IC. The first IC comprises first image processing circuitry, first display panel driver circuitry, and first communication circuitry. The first image processing circuitry is configured to generate a first overlay image by overlaying a first partial input image with a first image element based on first partial input image data representing the first partial input image and first image element data representing the first image element. The first display panel driver circuitry is configured to drive a display panel based on the first overlay image. The first communication circuitry is configured to output second image element data representing a second image element to the second IC.

Video displayers are provided for detecting image freezing in a video displayer with a multi-layer panel including a front layer and a pixel layer emitting pixel light in emitting direction towards the front layer. Front layer and pixel layer are configured to let light through. Video displayers further include a light reflector arranged in the multi-layer panel between pixel layer and front layer to reflect the pixel light from pixel layer in reflection direction towards pixel layer; a light sensor arranged to receive the reflected pixel light at receiving location and sense light variations in received reflected pixel light; and a control unit to receive light variations sensed by light sensor and to detect image freezing depending on received sensed light variations. Methods and computer programs implementing such methods are also provided which are performable by proposed video displayers.

A lighting system includes an LED array having a plurality of LED pixels and a power controller. The power controller adjusts a supply voltage for powering the LED pixels based on one or more conditions of the LED array. The power controller may determine the supply voltage based on process data of the LED array. The power controller may adjust the supply voltage based on an operating temperature of the LED pixels and the amplitude of a current driving the LED pixels.

A first input unit in a head-up display obtains a distance to an object. A second input unit obtains a user's eye position. An optical system projects, into the user's field of view, a virtual image of an image displayed on a display panel. A processor causes the display panel to display a parallax image. An optical element causes a first image displayed on the display panel to reach the user's first eye and a second image on the display panel to reach the user's second eye. The processor causes the display panel to display an image element in the parallax image as at least partially superimposed on the object. The processor performs first control to fix, in response to the distance to the object greater than or equal to a predetermined first distance, parallax of the image element to a value other than 0 corresponding to the first distance.

A head-up display includes a display panel, a reflective optical element, a controller, and an obtainer. The display panel displays a first image. The reflective optical element reflects image light from the first image displayed by the display panel. The controller controls a position at which the first image is displayed on the display panel. The obtainer obtains, as positional information, a position of an eye of a user. The controller changes the position at which the first image is displayed on the display panel in accordance with the positional information.

A head-up display is mountable on a movable body, and includes a first display panel, a reflective optical element, and an optical member. The first display panel displays a first image. The reflective optical element at least partially reflects image light from the first image displayed by the first display panel toward a user of the movable body. The optical member is between the display panel and the reflective optical element and is light transmissive. The display panel includes a surface facing a surface of the optical member. Each of the surface of the display panel and the surface of the optical member includes a reflection reduction layer to reduce light reflection.
