A HUD apparatus is provided. The HUD apparatus is provided with: an optical source part having a light emission element; a condenser lens, which faces the optical source part, and collects light source light; a field lens, which further collects the light source light transmitted from the condenser lens side, and which projects light at a predetermined angle; and an image formation element, which forms an image when the light source light transmitted from the field lens side is inputted thereto, and which projects light of an image toward the windshield side. The field lens has a composite surface on at least one of the condenser lens side and the image formation element side, the composite surface having multiple continuous optical surfaces. The condenser lens has a diffusion part that diffuses the light source light.

A display apparatus mountable on a mobile object, which: obtains a display location and a movement direction of a virtual object to be displayed in a display area of the display apparatus so as to be overlaid in a real world, the virtual object to be moved relative to movement of the mobile object; estimates a time it will take for the virtual object to move from the display location to a border of the display area, or a distance between the display location of the virtual object and the border of the display area, each based on the display location and the moving direction of the virtual object; determines a display form of the virtual object based on the estimated time or the estimated distance; and causes the virtual object be displayed in the determined display form, such that the virtual object changes the display form while moving in the display area.

The present invention relates to a rotating head-up display device, which includes a base, a rotating module, a display module and a reflective module,

The fixed portion of the rotating module fixed to the base and the rotating portion of the rotating module fixed to the display module are provided as image rotating mechanism, and the adjustment module is provided to operate for rotating and projecting enlarged images, to thereby conveniently rotate images corresponding to horizontal screen and vertical screen of a smartphone or a tablet.

The present disclosure relates to a display apparatus for a vehicle. According to an embodiment of the display apparatus for a vehicle includes: a picture generation device; an optical path separator to reflect a first projection from the picture generation device; a light transmittance changer to change light transmittance of the first projection image; a screen onto which the first projection image passing is projected; and a signal processing device to control light transmittance of the light transmittance changer, wherein the picture generation device outputs a second projection image to a windshield. Accordingly, a luminance difference between the first projection image projected onto the screen and the second projection image reflected on the windshield may be reduced while implementing a plurality of displays in an integrated manner.

A driving assistance apparatus includes a controller programmed to perform a deceleration assistance process of assisting in decelerating a vehicle before the vehicle arrives at a deceleration object, and to control a display apparatus to display, in a first display area, first notification information for notifying an occupant of the vehicle of the deceleration object that is a target for the deceleration assistance process. When a first object and a second object that is different from the first object are both detected as the deceleration object and the second object is the target for the deceleration assistance process but the first object is not the target for the deceleration assistance process, the controller is programmed to control the display apparatus to display, in a second display area, second notification information for notifying the occupant of the first object, the second display area is different from the first display area.

Methods and apparatus are disclosed for hue adjustment of a vehicle display based on ambient light. An example vehicle includes a display, an ambient light sensor to monitor ambient light of the vehicle, and a master lighting controller. The example master light controller is to determine a target hue for the display based on the ambient light, compare the target hue to a current hue of the display, and, in response to the target hue being different than the current hue, adjust the current hue to the target hue.

A moving object including a display apparatus capable of performing highly visible display is provided. The moving object includes a display unit, an imaging unit, an arithmetic unit, and a control unit. The display unit has a function of displaying a display image. The imaging unit has a function of obtaining a first captured image including the display image and an external view overlapping with the display image. The arithmetic unit has a function of comparing a color of the display image and a color of the external view and correcting the color of the display image on the basis of a comparison result. The control unit has a function of controlling running of the moving object on the basis of the first captured image.
