Abstract: The present invention contributes to safe driving by facilitating recognition of the timing at which driving assistance is switched. In the present invention, an advance notice display unit obtains information relating to vehicle driving assistance to be disabled and displays a advance notice image for giving advance notice of disabling of the driving assistance on the basis of said information, and a completion display unit obtains information relating to the detection of a disabling operation required for disabling the driving assistance and/or the completion of disabling of the driving assistance and displays a completion image for giving notice of the completion of disabling of the driving assistance or the completion of the disabling operation on the basis of said information.

Abstract: 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.

Abstract: A display device includes: an illuminating unit having a light source unit emitting light; an illumination control unit controlling the illuminating unit; a display element forming an image using illuminating light from the illuminating unit; a display control unit controlling the display element; a control unit controlling the illumination control unit and the display control unit based on a video signal; and a detection unit detecting the output intensity of the light source unit at that time. The control unit stores a control value corresponding to a target output intensity of the light source unit, and based on a difference between the to target output intensity and the output intensity at that time, the control unit determines a correction value for correcting the control value, and based on a control correction value obtained by correcting the control value using the correction value, the illumination control unit drives the light source unit.
