As the brightness increases, the brightness can be controlled to be gradually brighter than the reference brightness.

For example, when the measured distance between the camera 1401 and the subject 1402 is shorter than the reference distance 1403 (1403-1) by applying the AMOLED brightness described above in FIG. 13 to FIG. 14, the flash is activated. Instead, the brightness of the AMOLED screen may be controlled to gradually decrease as the subject 1402 is closer to the camera 1401 .

At this time, as a method of controlling the brightness using the screen AMOLED brightness, the screen AMOLED brightness is gradually darkened or gradually brightened based on the white color of the screen AMOLED color according to the ambient brightness measured by the illuminance sensor. You can control the brightness by automatically adjusting with .

If the user wants a warm feeling of brightness, the screen AMOLED brightness is automatically adjusted to gradually darker brightness or gradually brighter brightness based on the warm color (eg, red) of the screen AMOLED color, thereby adjusting the brightness. You can control it.

If the user wants cool brightness, the screen AMOLED brightness is automatically adjusted to gradually darker brightness or gradually brighter brightness based on the cool color (eg, blue) of the screen AMOLED color. You can control it.
