  • Patent number: 10732412
    Abstract: A display device for a vehicle displays an image at the time of seeing a three-dimensional object for distortion correction formed in a virtual space, from a reference eye point of a driver, on a display, as a display image. A controller performs texture mapping by pasting an original display image to the three-dimensional object for distortion correction, in the virtual space, and adjusts the three-dimensional object for distortion correction, according to a positional change between the reference eye point and an actual eye point. An adjustment unit changes a position of the three-dimensional object for distortion correction from a reference position, according to the positional change.

  • Publication number: 20190143816
    Abstract: A vehicle display device acquires a plurality of point positions of a pair of white lines interposing a traffic lane extending forward of a vehicle from a frontward image. Interpolation formulas are created in a direction in which a plurality of point positions are continuous along the white lines, respectively. A base point is determined on any one of the interpolation formulas on the basis of distance information to an intersection forward of the vehicle. A road shape model is created such that a plurality of finite element models defined by the base point and a plurality of vertexes set on the interpolation formulas, respectively, directed from the base point to the vehicle side are arranged between a pair of interpolation formulas.

    Abstract: A vehicle display device includes a vehicle front side camera that acquires a plurality of front area images by sequentially capturing a real landscape in front of a vehicle chronologically, an image analyzing unit that detects a position of a white line extending from an own vehicle side to an area in front of the vehicle in each of the front area images, and a controller that acquires an information image to be informed to the driver. The controller causes the information image to he displayed superimposed on the real landscape in a shape based on a shape of the white line in the real landscape obtained from a position of the white line.

  • Publication number: 20180211635
    Abstract: A head-up display device includes: a reflection member disposed in front of a driver who drives a vehicle; a projection unit configured to project light toward the reflection member and display a virtual image in a region superimposed on a superimposing display target when viewed by the driver; and an imaging unit configured to take an image of a region in front of the vehicle to generate a front image that is an image of the region in front of the vehicle. The projection unit adjusts a luminance distribution of a virtual image in accordance with a luminance distribution of a region of the superimposing display target in the front image.

  • Publication number: 20160274658
    Abstract: The display content of an instrument is automatically changed by detecting changes in a viewpoint position EP and a visual line direction DD. In a case of 2D drawing, the instrument is changed by combinations of enlargement, reduction, movement, and the like. In a case of 3D drawing, a stereoscopic image is rotated at its location. In a case of approach of a viewpoint, the stereoscopic image is returned to a standard state focusing on visibility. In a case of separation of the visual line, the stereoscopic image is rotated in a direction of going further away, and thus a stereoscopic effect is emphasized. Regarding an instrument matching a visual line direction, a stereoscopic image is directed toward the front side, and thus visibility is improved. In a case where the visual line direction is slightly deviated, the stereoscopic image is maintained in a state of being directed toward the front side, and, in a case where the visual line direction is greatly deviated, tracking control is gradually finished.

  • Patent number: 8570308
    Abstract: A trapezoid-shaped motion blur pointer image is composed of edges of normal pointer images. The normal pointer image and the motion blur pointer image are not overlapped with each other to prevent unevenness in brightness. The brightness of the motion blur pointer image is even in a whole area of the motion blur pointer image. The brightness of the motion blur pointer image has an inverted relationship with an area thereof, or is varied corresponding to a rotation speed of the pointer image.

  • Patent number: 8384619
    Abstract: When switching a motion blur pointer image to a normal pointer image, an intermediate pointer image is displayed between the motion blur pointer image and the normal pointer image. The intermediate pointer image is a rectangle, and coordinates of vertexes of the rectangle are composed of coordinates of vertexes of the motion blur pointer image and the next normal pointer image.

  • Patent number: 7944422
    Abstract: The present invention is to provide a liquid crystal display (LCD) meter apparatus having a small influence of a residual image of a pointer. The LCD meter apparatus for displaying a dial plate and a pointer includes a moving-speed calculating device for calculating the moving-speed of the pointer; and an image density changing device for reducing the image density of the pointer responding to the moving-speed of the pointer calculated with the moving-speed calculating device. The image density of the pointer becomes thinner as the moving speed of the pointer becomes faster so that an erasing time of the image becomes shorter or a residual image remains shorter. Both residual and latest images are displayed thinly, the plurality of the images including the residual images do not give a noticeable appearance so that the LCD meter apparatus provides a clear view.
