Publication number: 20240068833Abstract: A vehicle display device includes a display that is mounted on a vehicle and superimposes and displays an image on a real landscape in front with respect to a front windshield, a controller that controls the display, and a position information acquisition unit that acquires a position of a preceding vehicle. The controller calculates a first virtual straight line that connects the position of the preceding vehicle and a position of the vehicle. When the controller determines that the first virtual straight line is along a straight direction of the vehicle, the controller displays a marker image at a position below the preceding vehicle. When the controller determines that the first virtual straight line is inclined with respect to the straight direction, the controller performs display movement control to display the marker image so as to be shifted from the position below the preceding vehicle.Type: ApplicationFiled: August 22, 2023Publication date: February 29, 2024Inventors: Kazuyoshi Ogasawara, Takenobu Tomihira, Hiroki Kitahara

Publication number: 20160274658Abstract: 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.Type: ApplicationFiled: December 2, 2014Publication date: September 22, 2016Inventor: Kazuyoshi Ogasawara
