摘要： Provided is a head up display (HUD) device in which occurrence of postcard can be reduced. The HUD device causes an image to be visually recognized as a virtual image. The HUD device is provided with: a projector 100 that emits projection light including light indicating an image; a screen 60 which the projection light reaches; and a light shielding part S that shields at least a part of the projection light excluding the light indicating the image. The screen 60 has a display possible region Rc that is a range which the projection light can reach, and a display region Ra to which the image is projected.

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： Provided is a display device with which a suitable image can be displayed with a simple device configuration. The display device has: a display panel which displays an image on the basis of a plurality of image patterns; a plurality of light sources which illuminate, from the back surface, respective regions of the display panel that has been divided into a plurality of regions; a storage unit which stores luminance information in which the respective image patterns and the luminance of the respective light sources in the image pattern are associated with each other; and a luminance control unit which controls the luminance of each of the light sources on the basis of the luminance information. The luminance control unit gradually changes the luminance of the light sources from the luminance of the light source before a change to the luminance of the light source after the change.

摘要： The present invention enables prevention of collision with a forward obstacle by prompting an appropriate driving operation according to the relative speed or the relative distance between a host vehicle and the forward obstacle. 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.

摘要： Provided is a head-up display capable of achieving a balance in visibility between a virtual image and foreground displayed on each of a plurality of virtual display surfaces for virtual images. A first virtual image display surface and a second virtual image display surface are generated at different positions in the depth direction from the perspective of a viewer, and the ratio between the visibility level of a first virtual image displayed on the first virtual image display surface and the visibility level of a second virtual image displayed on the second virtual image display surface is gradually altered (increased or decreased) according to prescribed parameter information P which is presented as numerical values or in multiple levels.

摘要： A head-up display device is provided with: a combined light output unit which outputs combined light obtained by combining light emitted by a plurality of light sources which emit light having different wavelengths; and a heat dissipator which dissipates heat emitted by the light sources. The head-up display device displays a virtual image by means of the combined light. The plurality of light sources include a first light source which operates in a first operation guaranteed temperature band, and second light sources which operate in a second operation guaranteed temperature band having an upper limit higher than that of the first operation guaranteed temperature band. The first light source is provided in a location on the heat dissipator having a higher heat dissipation characteristic than the locations of the second light sources.

摘要： Provided is a gauge in which it is possible to suppress reductions in external appearance due to imperfections in an anti-reflection part. This gauge is provided with: a display part for displaying a measured quantity; a translucent plate positioned on the front-surface side of the display part, the translucent plate allowing visual confirmation of the display part through the translucent plate; a clamp part for clamping an end part of the translucent plate; and an anti-reflection part provided to the display part side surface of the translucent plate the anti-reflection part having a plurality of conical protrusions arrayed at a pitch equal to or less than the wavelength of visible light. The anti-reflection part is provided away from the end part of the translucent plate, and is provided so as not to contact the clamp part.
