Now, if the light intensity value that the first light sensor is measured changes little, user terminal carrys out adjusting screen backlight illumination according to the light intensity value that the first light sensor is measured can not cause too big impact to the visual experience of user. Now, if the environment light intensity value that the first light sensor is measured changes bigger, user terminal carrys out adjusting screen backlight illumination according to the light intensity value that the first light sensor is measured will cause bigger impact to the visual sense feeling of user, therefore, at this moment user terminal carrys out the light intensity value of testing environment by the 2nd light sensor, to determine the real light intensity value of environment. Visible, by implementing the method described by Fig. 2, user terminal only just need to carry out the light intensity value of testing environment when the amplitude that the light intensity value that the first light sensor is measured reduces is very big by the 2nd light sensor, do not need the light intensity value always being carried out testing environment by the 2nd light sensor, save CPU resource.
