Implementations of an in-vehicle display system may include: a first display device configured to irradiate a first area of a windshield of a vehicle with a first light constituting a first image and to display the first image as a virtual image of the first image in front of the first area; a second display device configured to display a second image as a real image in a second area of the windshield that is wider than the first area; and a control device configured to control the first display device and the second display device based on a travel state of the vehicle.

A vehicle display system includes a display device, a determiner, and a display controller. The display device is mounted on a vehicle. The determiner is configured to determine whether a person present outside the vehicle enters a blind spot of a driver of the vehicle. The display controller is configured to control, when the person enters the blind spot, the display device to display a warning to the person.

A microlens array includes N lenses ranging from a 1.sup.st lens to an N.sup.th lens and a lens arrangement area. N is a positive integer. The lens arrangement area has the N lenses arranged in array. The lens arrangement area receives light emitted from a light source. An i.sup.th (i being 1.sup.st to N.sup.th) lens satisfies a conditional expression below:

2020 where denotes an angle formed by a main-axis orientation of double refraction and a reference orientation.

A driver can intuitively and conveniently perform an operation for instructing passing to a vehicle. In a driving support device, an image output unit outputs, to a display unit, an image containing an own vehicle object representing an own vehicle and an another vehicle object representing another vehicle in front of the own vehicle object. An operation signal input unit receives an operation of a user for changing the positional relationship between the own vehicle object and the another vehicle object in the image displayed on the display unit. A command output unit outputs, to an automatic driving control unit, a command for instructing the own vehicle to pass the another vehicle when the positional relationship between the own vehicle object and the another vehicle object is changed such that the own vehicle object is positioned in front of the another vehicle object.

A multi-image head-up display device for displaying a plurality of virtual images at different projection distances from a driver of a vehicle includes a picture generating unit with an illumination source that may include a plurality of lasers of different colors to illuminate a spatial light modulator with a first light beam. The spatial light modulator includes blocks of modulating elements to diffract the first light beam to form first and second real images upon first and second respective projection surfaces, each spaced apart from the spatial light modulator by a different focal length. The blocks may be configured as Fourier and/or Fresnel diffractive optical elements. A projection assembly may magnify and direct the real images to the viewer as virtual images each having a different projection distance from the viewer. A method for generating a plurality of virtual images with a head-up display device is also provided.

An optical scanning apparatus includes a light source to emit light, a light deflector having a reflection face to deflect the light as a scan-use light to scan an image generation element by oscillating the reflection face, a light receiving element to receive a control-use light to generate a signal used for controlling a scanning condition of the scan-use light, and a control unit to control the scanning condition of the light deflector based on the generated signal.

An information provision device and an information provision method. Each of the information provision device and information provision method includes projecting an image light to a light transmission member so as to display a for-driver information image, sensing a relative distance of an object to be detected existing around the mobile object in the direction of travel, detecting a location of a viewpoint of the driver, and changing a position at which an object image indicating the object to be detected is displayed according to a result of the detecting so as to change a perception distance of the driver influenced by a motion parallax of the object image according to the relative distance of the object to be detected in the direction of travel.

An information provision device, information provision method, and a non-transitory recording medium storing a program for causing a computer to execute the information provision method. Each of the information provision device and the information provision method includes projecting an image light to a light transmission member to display a for-driver information image indicating for-driver information to be provided to a driver of a mobile object in a prescribed display area, and displaying at a first point where a normal for-driver information image is displayed a priority for-driver information image in place of the normal for-driver information image, where the displaying includes displaying the normal for-driver information image at a second point different from the first point for at least some of a period during which the priority for-driver information image is displayed at the first point.

A display device includes a beam generator and a holographic optical waveguide. The beam generator includes a display and is configured to generate beams having image information displayed on the display. The holographic optical waveguide is configured to display an image of a second size at a position at a first distance behind the display device based on the beams having the image information, the second size is a multiple of the first size of the display, and the multiple is greater than 1.

The present disclosure discloses a method and an apparatus for recognizing an obstacle to a vehicle. The method comprises: acquiring point cloud data of a target region by a lidar sensor and acquiring image data of the target region by using an image capturing apparatus; recognizing obstacle information in the point cloud data by a preset point cloud recognition model, and labeling a recognition result to obtain a first labeled result; recognizing obstacle information in the image data by a preset image recognition model, and labeling a recognition result to obtain a second labeled result; comparing the first labeled result with the second labeled result to decide whether the first and the second labeled result are identical; and determining a correct labeled result from the first and the second labeled result in response to the first and the second labeled result being not identical and outputting the correct labeled result.
