摘要： A head-up display device includes: light sources; a light source driver that drives the light sources; a second control unit that illuminates the light sources via the light source driver on the basis of illumination control data; and a DMD display element that generates display light on the basis of illumination light emitted by the light sources. The illumination control data includes control modes for generating the illumination light brightness corresponding to a requested brightness. The control modes have differing brightness ranges, which partially overlap each other. The second control unit switches modes between the control modes when the requested brightness has reached a mode switching value, which is located in a non-end part of an overlapping region where one of the brightness ranges of one of the control modes and another one of the brightness ranges of another one of the control modes overlap.

摘要： A head-up display device as a vehicle display device projects display light onto a front windshield of a vehicle, displays a virtual image by reflected display light, on the front windshield, so as to be superimposed on a real scene transparent through the front windshield, captures an image of a driver of the vehicle by projecting infrared light onto the driver, and detects the positions of the eyes of the driver based on the captured image. A control unit detects the position of a feature point of the face of the driver in the captured image and stores a positional relationship with the detected positions of the eyes, and, when it is difficult to detect the positions of the eyes in die captured image, estimates a viewpoint position of the driver based on the position of the feature point detected at this time and the positional relationship stored beforehand.

摘要： A navigation device includes an image display unit and a display control unit for controlling the display of the image display unit. The display control unit displays, in the image display unit, a map on a fixed scale in the form of a bird's eye view in which the front of the vehicle is overlooked, and displays a moving route by a guide line on the map until the distance to a guide point becomes a first display switching determination distance, when the distance to the guide point becomes the first display switching determination distance or shorter, increases a scale as the guide point is approached, and when the distance to the guide point becomes a second display switching determination distance or shorter, stops the increase of the scale, and displays, in an area where the guide line is displayed, a mark indicating a path at the guide point.

摘要： There is provided a lens array and an lens array capable of suitably preventing irregular brightness without reducing resolution. A micro lens array of a screen includes upper-level microlenses and lower-level microlenses which are formed on the incidence surface of the screen, which have the same effective diameter, and which have a structure that generates an optical path length difference Δ in transmission light. By disposing the upper-level microlenses and the lower-level microlenses at an interval based on the effective diameter, the basic periodic structure of a lens period is formed. Further, the upper-level microlenses and the lower-level microlenses form a basic block comprising a combination of the lenses having a structure that generates the optical path length difference. A concave-and-convex period PC based on the basic block is an integer multiple of the lens period.
