摘要： Provided is a head-up display device which can stably display a virtual image viewed so as to be stuck to a road surface, during traveling of a vehicle. A head-up display device according to the present invention is provided with a display means for projecting display light to a front window shield provided to a vehicle, and generating and displaying a virtual image, formed by the display light reflected at the front window shield, so as to be superposed on an actual scene seen through the front window shield. At least a part of a virtual image display region in which the virtual image is displayed is positioned below a road surface on which the vehicle travels.

摘要： The purpose of the present invention is to prevent stray light from reducing display quality. Provided is a laser light output control device that provides feedback on the intensity of the laser light emitted by a light source to thereby adjust the control value used by the light source to display an image M, wherein: an illuminance determination unit acquires an illuminance signal that allows estimation of the illuminance in the ambient environment or acquires a request luminance signal that externally controls the luminance of the image M, and determines the brightness of the ambient environment; an inspection time adjustment unit shortens a period Q during which the lights source emits inspection light Cd when the illuminance determination unit determines that there is a dark ambient environment, compared to when there is a bright ambient environment; and a light source control unit acquires an integrated value Sd of the intensity of the inspection light Cd emitted by the light source and adjusts a control value for driving the light source.

摘要： A head-up display (HUD) device displays a first virtual image in an area in which the first virtual image can be displayed, and displays a second virtual image in an area in which the second virtual image can be displayed. The HUD device includes: a rotation driving unit which changes an angle formed between the area in which the first virtual image can be displayed, and the area in which the second virtual image can be displayed; and a control unit which performs virtual image angle adjustment processing for adjusting the angle using the rotation driving unit, and, when performing the virtual image angle adjustment processing, virtual image position changing processing in which the position of the second virtual image in the area in which the second virtual image can be displayed is changed to inhibit deviation in the relative positional relationship between the first and second virtual images.

摘要： A projection-type display device includes: a reflection-type spatial optical modulation unit having movable reflection elements; a light source unit; and a control unit that controls the reflection-type spatial optical modulation unit and the light source unit. The control unit divides each frame of a displayed image into a display period during which the light source unit emits light and a non-display period during which the light source unit does not emit light. The control unit further divides, among a plurality of sub-frames forming the frame, each of display sub-frames included in the display period into division display sub-frames. The control unit causes at least one of the light emitting elements of the light source unit to emit light for each of the display sub-frames, and sets respective inclined states of movable reflection elements for each of the division display sub-frames.

摘要： A display system includes: a first display device displaying an image in a first region to cause the image to be visually recognized in a position at a first distance from a visual line of a driver of an auto-vehicle; a second display device displaying an image in a second region to cause the image to be visually recognized at a second distance greater than the first distance from the visual line; and a display controller displaying a warning image in the second region if a first condition is satisfied, moving the warning image to display a warning image in the first region if a second condition in which a warning level is higher than that of the first condition is satisfied after the first condition is satisfied, then updating the warning image to an updated warning image, and then moving the updated warning image to the second region.

摘要： A vehicular display device includes: an image display unit having a display screen capable of displaying an image at least in a part thereof; an image generation unit for generating the image to be displayed by the image display unit; and a projection unit for projecting the image toward a transparent windshield of a vehicle so that the image is reflected by the transparent windshield of the vehicle such that a user seated in the driver seat of the vehicle can view a virtual image. In accordance with a viewpoint position of the user, the image generation unit determines a length for display content in a use area of the display screen of the image display unit in a direction corresponding to a horizontal direction, the use area being an area used for displaying the image.

摘要： The present invention is capable of making it difficult to perceive the narrowness of a display area of a virtual image. Provided is a head-up display which projects display light on a transmission/reflection part to display a first virtual image in an area in which the virtual image can be displayed, said area being superimposed on an actual view outside of a vehicle, wherein, when deviation occurs in the relative positions of the actual view and the transmission/reflection part from the perspective of a viewer, a control unit enlarges a virtual image display area, which sets the range in which the first virtual image is displayed within the area in which the virtual image can be displayed, so as to be larger than normal.

摘要： A display device includes: a control unit that causes any one of light sources to emit light, each of the light sources emitting light of a different color, generates illumination light of a color from the light emitted from the light sources, using a field-sequential method in which the light sources for emitting light are switched in sequence, and reflects toward a screen, through a reflection unit, the light that corresponds to the display image from among the illumination light; a temperature detection unit for detecting the temperature of a display element; and a temperature adjustment unit for adjusting the temperature of the display element. The control unit stops supplying current to the light sources and supplies current at a first current value only to the temperature adjustment unit when the detected temperature is within a low-temperature or high- temperature non-displayed range of the display element.

摘要： In the case in which a loss of the viewpoint position of a driver occurs when a viewpoint position follow-up warping control is executed to update warping parameters according to the viewpoint position of the driver, and then the viewpoint position is re-detected, it is suppressed that the appearance of an image instantaneously changes in accordance with the update of the warping parameters and the driver is caused to feel uneasy. When the viewpoint loss in which at least one position of the right and left viewpoints becomes unclear is detected, a control unit, which executes the viewpoint position follow-up warping control, maintains, in a viewpoint loss period, the warping parameters set immediately before the viewpoint loss period, and, when the viewpoint position is re-detected after the viewpoint loss period, invalidates at least one warping process using the warping parameters corresponding to the re-detected viewpoint position.

摘要： A head-up display apparatus prevents a driver from being confused when, for example, the number of overlaid images for alerting or emphasizing that are overlaid on an object increases due to the cutting-in of another vehicle, resulting in overlap between the overlaid images or between an overlaid image and another object resulting in an unclear correspondence relationship between the overlaid images and objects. A display control unit has: an overlap determination unit that, if a first overlay image is overlaid on a first object and a second object as a cut-in object is detected, determines the presence or absence of overlap between the overlaid images or the like; and a visibility control unit that, if the overlap occurs, makes the visibility of the first overlay image overlaid on the first object lower than the visibility of the second overlay image overlaid on the second object.
