Abstract:
1. A display adjusting device adapted for adjusting display parameter(s) of a display unit comprising: a light sensing unit for sensing an environmental illumination associated with the display unit; an image capturing unit for capturing an image of a user in front of the display unit; and a controlling unit, electrically connected to the display unit, the light sensing unit and the image capturing unit, for selectively adjusting a first display brightness of the display unit to a second display brightness according to the environmental illumination, calculating a distance between eyes of the user and the display unit according to the image, and selectively adjusting the second display brightness to a third display brightness according to the distance; wherein the controlling unit judges whether the distance is larger than a first threshold or smaller than a second threshold, the first threshold is larger than the second threshold; the controlling unit judges that the second display brightness is smaller than or equal to a maximum display brightness when the distance is larger than the first threshold, the third display brightness is equal to the second display brightness when the second display brightness is equal to the maximum display brightness, the third display brightness is larger than the second display brightness when the second display brightness is smaller than the maximum display brightness; the controlling unit judges that the second display brightness is larger than or equal to a minimum display brightness when the distance is smaller than the second threshold, the third display brightness is equal to the second display brightness when the second display brightness is equal to the minimum display brightness, the third display brightness is smaller than the second display brightness when the second display brightness is larger than the minimum display brightness; the third display brightness is equal to the second display brightness when the distance is between the first threshold and the second threshold.
