1. A method for processing information, applicable in an electronic device comprising a display unit, characterized in that, the method comprises the steps of:
sampling a parameter information, when contents are being displayed on the display unit;
determining whether the parameter information satisfies a predetermined first condition; and
adjusting a displayed parameter value corresponding to display of the display unit from a first value to a second value different from the first value, so as to improve contrast of the contents under ambient light where the electronic device is located, when the parameter information satisfies the predetermined first condition;
wherein the parameter information comprises behaviour features using the electronic device;
wherein a process of determining whether the parameter information satisfies the predetermined first condition includes determining whether the behaviour features indicate that a light illumination intensity corresponding to the ambient light is larger than a threshold value of a light illumination intensity for a user;
wherein the process of determining whether the behaviour features indicate that the light illumination intensity corresponding to the ambient light is larger than the threshold value of the light illumination intensity for the user includes:
determining whether the behaviour features indicate a first shading object and a head of the user meet a predetermined first relationship, wherein the predetermined first relationship is: a distance of the first shading object from the head being less than a predetermined distance threshold value, or the first shading object being in contact with the head, or an angle between the first shading object and the head being within a predetermined range of angles;
wherein when a surface of the display unit is provided with an optical unit, the displayed parameter value is an optical parameter value of the optical unit, and the process of adjusting the displayed parameter value from a first value to a second value different from the first value is to adjust the optical parameter value from a first optical parameter value to a second optical parameter value different from the first optical parameter value;
wherein a first absorption capability of the optical unit to the ambient light when the optical parameter value is the second optical parameter value, is larger than a second absorption capability of the optical unit to the ambient light when the optical parameter value is the first optical parameter value; and
wherein a third absorption capability of the optical unit to the first light corresponding to the contents when the optical parameter value is the second optical parameter value, is larger than a fourth absorption capability of the optical unit to the first light when the optical parameter value is the first optical parameter value.
