Abstract
In a vehicle display device, in accordance with a change in a degree of lightness around a vehicle based on illuminance detected by an illuminance sensor that detects illuminance around the vehicle, a brightness adjustment unit makes a response of brightness adjustment of a virtual image to the detected change in illuminance relatively fast when an age of a driver estimated by an age estimation unit is relatively high, and makes a response of the brightness adjustment of the virtual image to the detected change in illuminance relatively slow when the age of the driver is relatively low.
Claims4
A vehicle display device comprising:
- an image display unit that projects a display image on a projection target member of a vehicle and causes a driver of the vehicle to visually recognize a virtual image corresponding to the display image projected on the projection target member;
- an illuminance detection unit that detects illuminance around the vehicle;
- an age acquisition unit that acquires an age of the driver;
- and
- an adjustment unit that adjusts brightness of the virtual image on a basis of the illuminance detected by the illuminance detection unit and the age acquired by the age acquisition unit, wherein
- in accordance with a change in a degree of lightness around the vehicle based on the illuminance detected by the illuminance detection unit, and
- the adjustment unit
- makes a response of brightness adjustment of the virtual image to the change in the detected illuminance relatively fast when the age of the driver acquired by the age acquisition unit is relatively high, and
- makes a response of the brightness adjustment of the virtual image to the change in the detected illuminance relatively slow when the age of the driver is relatively low.
