  • Patent number: 11961430
    Abstract: A display device for a vehicle includes a moving speed calculation unit that calculates a moving speed of a pupil based on a position of the pupil detected by a pupil detection unit. In a case in which the moving speed of the pupil is equal to or lower than a threshold, a pupil diameter calculation unit calculates a pupil diameter at a present time based on the pupil at the present time, and outputs the calculated pupil diameter at the present time to a brightness adjustment unit. On the other hand, in a case in which the moving speed of the pupil exceeds the threshold, the pupil diameter calculation unit outputs a pupil diameter calculated at a previous time to the brightness adjustment unit as the pupil diameter at the present time.
