Abstract
When display control for a display device installed in a vehicular cabin is to be performed, an environmental light intensity is detected by a light sensor, and variation time function of the environmental light intensity is calculated. On the basis of the light intensity variation time function, a variation time function of a human pupil open degree is predicted. On the basis of the predicted time function, an optimal value of brightness of the display device is determined to perform display brightness control.
