Abstract: The purpose of the present invention is to enable information presented by an additionally displayed virtual image to be displayed in an easily recognizable manner. A projection unit projects, towards a projection-receiving part, display light capable of displaying virtual images in positions having different display distances from a viewer. A display distance determination unit is capable of adjusting, in a depth direction, the display distances of the virtual images displayed by the projection unit. If a display addition determination unit determines that a virtual image is to be additionally displayed, the display distance of an existing virtual image already displayed and the display distance of a virtual image to be additionally displayed are made to be different.

Abstract: The purpose of the present invention is to provide a display device for a vehicle which is capable of avoiding NAND flash memory data loss. Provided is a display device for a vehicle, comprising: a display unit 6 which displays vehicle information; a NAND flash memory 1 which stores, together with an error correction code, data which is related to the display of the display unit 6; and a control unit (for example, a second control unit 2) which causes the display 6 to display the vehicle information using said data. When a load upon the vehicle is low, such as when a switch key for commencing the driving of the vehicle is off, the control unit (for example, a first control unit 3), as a data loss avoidance process, assesses, with the error correction code, whether an error is present in the data which is recorded in the NAND flash memory 1. If the error is present in the data, the control unit (for example, the first control unit 3) corrects the error with the error correction code.

With respect to a standard display position at which a virtual image is normally displayed in association with an attention object in an actual scene ahead of a host vehicle, the virtual image is displayed at a corrected display position which is on the lower side in the vertical direction and/or on the near side in the depth direction when seen from a viewer, depending on the relative speed or the relative distance between the host vehicle and the attention object in the actual scene.

Abstract: The present invention suppresses an increase in optical system curvature, thereby enabling miniaturization. An image forming unit reflects image light beams, which were projected from each region along a first direction of a display, towards a reflection unit so that the image light beams intersect between the image forming unit and the reflection unit. A light distribution adjustment unit is disposed between a light source and a display, and in the first direction, adjusts the orientation of illumination light beams projected from the light source so that the illumination light beams are incident on the display as convergence light.

Abstract: The present invention displays multiple images at different locations in the depth direction, while suppressing a decline in the resolution of each image, using projected light emitted from a single projector. A projector emits first projection light and first projection light that have a first projection distance. The projection distance P of the second projection light is shortened to a second projection distance that is shorter than the initial first projection distance, by positioning a projection distance shortening unit having a positive refractive power along the path of the second projection light between the projector and a second screen. Furthermore, no optical members having a negative refractive power are positioned along the optical path of the first projection light from the projector to a first screen on the projector side relative to the second screen.
