Specifically, referring to fig. 4, fig. 4 is a schematic view of a refined flow of step S40 in fig. 3, where step S40 includes:
step S41, substituting the screen brightness, the included angle and the gray value into a preset formula to calculate color values of the icons and the characters in the icon interface;
and step S42, adjusting the icons and the characters according to the color values.
The mobile terminal substitutes the current screen brightness, the included angle between the screen and the horizontal line where the eyes of the user are located and the gray value of the screen wallpaper into a preset formula so as to calculate the color values of the icons and the characters in the icon interface. The preset formula is a color value adjusting formula stored in a memory in advance, the gray value of the screen wallpaper is recorded as A, the included angle between the screen and the horizontal line where the eyes of the user are located is recorded as B, the screen brightness is recorded as C, and the adjusting color value is value, the preset formula can be expressed as value-kA + tB + sC, wherein the value range of A is 0-255, the value range of B is 0-90 degrees, the value range of C is 0-255, and k, t and s are all larger than zero. When k, t and s all take 1, the preset formula is changed into value-a + B + C, and when k takes 1, t takes 2 and s takes 1, the preset formula is changed into value-a +2B + C, that is, the values of k, t and s can be set according to the actual needs of the user, and certainly, the color value can be calculated according to the preset values of k, t and s. The color value is an RGB value of a color, and in an RGB color mode, the color is formed by mixing red, green, and blue.
