Abstract: An extraction unit (70: S310) extracts reflection points which are located in a judgment target range and are stationary, as judgement target points. A group generation unit (70: S330-S350) uses one of the judgement target points as a starting point and generates a connected group by extracting the judgment target points which are successively aligned at intervals less than or equal to an acceptable connection distance from the starting point. A judgement unit (70: S360-S420) judges, if judgement conditions are satisfied, that a vehicle is travelling in a special environment in which the accuracy of object information is decreased. The judgement conditions include that a judgment point which is set in accordance with the number of the judgment target points belonging to the connected group generated by the group generation unit exceeds a point threshold value.

Abstract: Provided is a head-up display device with which it is possible to suppress any increase in the temperature of a liquid crystal display. The head-up display device comprises: a light source; a liquid crystal display 1 that radiates display light L showing an image based on illumination light C1 from the light source; and a reflective polarization member 4a positioned between the light source and the liquid crystal display 1 in the light path of the illumination light C1 from the light source, the reflective polarization member 4a reflecting a component, in the illumination light C1 from the light source, that follows a reflection axis in a direction away from the liquid crystal display 1, and transmitting a component that follows a transmission axis intersecting the reflection axis toward the liquid crystal display 1. The liquid crystal display 1 comprises an absorptive polarization member 1e provided at a position closer to the light source than is a liquid crystal part 1a of the liquid crystal display 1, the absorptive polarization member 1e absorbing a component, in incident light, that follows an absorption axis, and transmitting a component that follows a transmission axis intersecting the absorption axis. The reflective polarization member 4a is provided in an orientation such that the reflection axis of the reflective polarization member 4a follows the absorption axis of the absorptive polarization member 1e.
