Abstract: An electronic mirror system presents circumstances surrounding a moving vehicle by displaying an image presenting the circumstances surrounding the moving vehicle. The electronic mirror system includes an image display and an optical system. The image display displays, every time image data is acquired from an image capturing unit, the image, based on the image data acquired from the image capturing unit, on a display screen. The image capturing unit continuously shoots video presenting the circumstances surrounding the moving vehicle. The optical system condenses, into an eye box, a light beam representing the image displayed on the display screen to make a user, who has a viewpoint inside the eye box, view a virtual image based on the image displayed on the display screen. The display screen is arranged to be tilted with respect to an optical path that leads from the display screen to the optical system (30).

Abstract: A display system of the present disclosure forms an AR route by shifting node information included in road map data to a lane on which a subject vehicle is to travel on the basis of lane information. Thus, it is possible to display the AR route which matches a shape of a route on which the subject vehicle is to travel without providing a feeling of strangeness while resolving inconvenience that the AR route is largely displaced from the route on which the subject vehicle is to travel at positions such as an intersection and a branch point, where a plurality of roads intersect.

Abstract: An information display device includes a surrounding environment detector, a vehicle information acquirer, a predictor, an avoidance path provider, and an information display. The surrounding environment detector detects position relevant information related to a position of at least a surrounding object in a surrounding environment of a vehicle. The vehicle information acquirer detects vehicle information including a speed and a steering direction of the vehicle. The predictor predicts a contact of the vehicle with the surrounding object, based on the position relevant information and the vehicle information. When the predictor has predicted that there is a possibility of the contact of the vehicle with the surrounding object, the avoidance path provider assumes an avoidance path for avoiding the contact, based on the position relevant information and the vehicle information. The information display displays the avoidance path.

Abstract: A screen includes a surface inclined with respect to a reference plane. A driver moves the screen in a movement direction orthogonal to the reference plane. When forming a first virtual image serving as a virtual image on a first virtual plane whose inclination angle α with respect to an optical axis of a projector is smaller than a predetermined value, a controller is configured to hold the screen in the movement direction. When forming a second virtual image serving as the virtual image on a second virtual plane whose inclination angle ß with respect to the optical axis of the projector is larger than the predetermined value, the controller is configured to move the screen in the movement direction.

Abstract: In a display device, an irradiation unit includes an imaging optical system. The imaging optical system scans and irradiates a front surface of a screen with light to form an image. The light passing through the screen and output from the screen in a movement direction is incident on a projection unit as incident light. The projection unit irradiates a reflective member with the incident light to allow the reflective member to reflect the incident light to form a virtual image corresponding to the image in a target space. A locus of a focal position of the imaging optical system when the irradiation unit wholly scans the front surface of the screen is within a range between the front surface of the screen at a first position and the front surface of the screen at a second position.

Abstract: An image display system includes a display unit displaying an image, a projection unit projecting in a target space a virtual image corresponding to the image with an output light of the display unit, a body unit provided thereto the display unit and the projection unit, and an image producing unit including a first correction unit and a second correction unit. The first correction unit performs a first correction processing of correcting, based on a first orientation signal indicative of a first orientation change of the body unit, a display position of the virtual image in the target space. The second correction unit performs a second correction processing of correcting, based on a second orientation signal indicative of a second orientation change of the body unit which is faster than the first orientation change, the display position of the virtual image in the target space.

Abstract: An event prediction system includes an accumulation unit and a generator. The accumulation unit accumulates a plurality of pieces of learning data each including history information representing a situation of a mobile object upon occurrence of an event associated with driving of the mobile object. The generator generates a prediction model for prediction of relative coordinates of an occurrence place of the event relative to the mobile object by using the plurality of pieces of learning data. Each of the plurality of pieces of learning data further includes label information representing the relative coordinates of the occurrence place of the event relative to the mobile object.

Abstract: To provide a display device that can suppress generation of a double image. Display device includes plate-shape windshield having translucency and a projection unit that projects light expressing an image onto windshield such that the light is reflected toward a user by windshield. The projection unit changes a display distance between an eye of the user and a position of an image visually recognized as a virtual image by the user through windshield by the light projection. Windshield is formed such that a wedge angle that is of an angle formed between a front side and a back side at a region located at any level of windshield is continuously decreased with increasing level.

Abstract: An image display system includes a body, a first correction unit, and a second correction unit. The body houses a display unit to display an image and projects a virtual image, corresponding to the image, onto a target space using outgoing light of the display unit. The first correction unit corrects for distortion of the image. The second correction unit corrects a display location of the image on the display unit in accordance with an orientation signal representing a change in orientation of the body. Each of divisional areas of a display screen of the display unit is assigned with a distortion correction parameter for correcting for the distortion of the virtual image. The first correction unit applies distortion correction to each of the image regions of the image on the display screen based on a distortion correction parameter assigned to a divisional area where the image region is displayed.
