摘要： A head-up display device and a self-checking method therefor are provided, which are able to suppress the direct output of a laser beam to outside. A reflecting means (70) reflects an image generated by a scanning means (30) and projects the image outside of a case (80), and an angle-adjusting means (301) adjusts the reflecting means (70) to a desired angle. After the ignition switch of the vehicle is turned on, a light-emitting means (10) outputs a scanning laser beam, and the value of the current flowing to the light-emitting means (10) is detected, or a first light intensity, which is the light intensity of the scanning laser beam, is detected. For a period extending at least from the output of the scanning laser beam by the light-emitting means (10) to the establishment of a predetermined condition, the angle-adjusting means (301) is controlled such that the reflecting means (70) is set to a non-visible position at which the scanning laser beam is reflected inside the case (80).

摘要： A display device is provided with: a display means that is mounted on a vehicle, that displays a virtual image of a picture by projecting, on a windshield, display light representing the picture, and that emits the display light; an identification means that identifies a target (W) outside the vehicle; a control means that causes a first captured image (Va), visually recognized as being superposed on at least a part of the target (W), to be displayed in the picture; and a vibration detection means that detects the amount of vibration of the vehicle. The control means, when the amount of vibration detected by the vibration detection means exceeds a threshold value, causes a second captured image (Vb) to be displayed instead of the first captured image (Va). The second captured image (Vb) is an image of which a color shade difference between pixels configuring an image end and a region outside the image and adjacent to the image end is decreased compared with the first captured image (Va). In this way, even if a position error is caused between a predetermined object and a captured image displayed while being superposed on the object, a sense of discomfort that a viewer may feel can be decreased.

摘要： A display device capable of obtaining stable light output even in a state of low brightness and capable of displaying desired display colors is provided. An output control means (80) causes image-forming light to be emitted from a laser source (10) on the basis of image information when the scanning position of an RGB laser beam according to a scanning means is within a display range (20), and causes detection light to be emitted from the laser source (10) when the scanning position is outside the display range. In addition, the output control means (80): changes the drive current of the laser source (10) according to a first current value that is less than a threshold current value, and second and third current values that are greater than or equal to the threshold value, when the scanning position according to the scanning means (20) is outside the display range; and drives the laser source (10) according to the drive current obtained by calculating the current-light output characteristics on the basis of the light intensity detected by a laser beam detection unit (40).

摘要： In the present invention, it is possible to precisely adjust the intensity of light emitted from a light source and ensure a dynamic range from high brightness to low brightness even in a field-sequential color drive format for turning light on and off at high speed. A light intensity detection signal (SFB) indicative of the intensity of light emitted by a light source (11) is acquired, and on the basis of the light intensity detection signal (SFB) and a set reference signal (SA), a comparison circuit (410) generates a comparison signal (SB) indicative of turning ON and OFF. Within a sub-frame period, a logic circuit (420) repeats turning ON/OFF based on a pulse signal inputted from the comparison circuit (410), and outputs a lighting signal (SD1) for causing the light source (11) to emit light in accordance with the reference signal (SA) which is a set value, and outputs a non-lighting signal (SD2) for causing the light source (11) to not emit light in accordance with a set value.

摘要： Provided is a field sequential image display device with which the service life of DMD display elements can be lengthened. In the present invention, each frame (F) is equipped with: a display period (Fa), wherein a display control portion (92) normally drives multiple mirrors (E) and a lighting control portion (91) drives a first lighting portion (11r) and a second lighting portion (11g), thereby displaying a display image (D) in display elements; and a non-display period (Fb), wherein the display control portion (92) drives the multiple mirrors (E) for a non-display period and the lighting control portion (91) turns off the first lighting portion (11r) and the second lighting portion (11g), and thus the display image (D) is not displayed in the display elements. On the basis of prescribed luminance control conditions, when the luminance of the display image (D) is to be lower than a predetermined threshold luminance value (T), a control unit (90) lowers the display period ratio (A), which is the ratio of the display period (Fa) in each frame period.

摘要： Provided is a heads-up display device that stably achieves a low brightness display in which the display does not feel too bright in a dark environment at night, which further does not give a vehicle driver discomfort with continuous changes in brightness, and which has excellent white balance in the entire range of display brightness. A heads-up display device (1) is provided with an external light illuminance detection section (70) that detects the illuminance of external light and adjusts the display brightness (B) for display of images, which are displayed, on the basis of external light illuminance (P) measured by the external light illuminance detection section (70). The heads-up display device (1) is further provided with a display brightness adjusting means (81a) that adjusts the display brightness (B) of the display image to a low level when a display image is displayed in a low brightness region that is lower than a prescribed brightness by controlling the polarization angle of a polarized light control element (11) and adjusting the transmittance (Z) for laser light (R, G, B) in a polarized light section (14).
