For example, in a real scene outside the vehicle, the distant target is usually located at a higher (ie, deeper) position, and vice versa. Therefore, by rotating the mirror unit along the horizontal axis, the image can be adjusted to positions of different heights, so that the driver can obtain such things as navigation, road sign, speed, and without adjusting the line of sight during normal driving.

  • the adjustment unit 104 further includes a second mechanical motor device (not shown) for rotating the mirror unit 103 along a vertical axis.
  • the driver When the vehicle turns or is about to turn, the driver usually adjusts the line of sight to the direction of the vehicle's turn (and no longer pays attention to the front). Therefore, by rotating the mirror unit along the vertical axis, the image can be adjusted to the direction in which the vehicle turns, so that the driver can obtain, for example, navigation, road sign, speed, without adjusting the line of sight during normal driving.

  • the adjustment unit 104 adjusts the direction of the mirror unit 103 according to the traveling speed such that the depth of the image increases as the traveling speed increases.
  • the inventors realized that as the driving speed increases, the driver usually adjusts the line of sight to a higher position, thereby paying attention to the road conditions further away, and vice versa;
  • the speed adjusts the direction of the mirror unit so that the driver can obtain information such as navigation, road sign, speed, oil quantity, etc. without adjusting the line of sight during normal driving.
  • the head up display 100 further includes a housing unit 109 that houses the digital light processing unit 101, the mirror unit 103, and the adjustment unit 104, and the housing unit 109 Also included is a transparent portion 110 between the mirror unit 103 and the reflective surface 301.
