The value of the target R component in the first Pixel Information after adjustment is represented with r, the value of the target G component in the first Pixel Information after g represents adjustment, b represent the value of the target B component in the first Pixel Information after adjustment, set (the r of three component values in the first Pixel Information then after adjustment, g, b) be specially:
In step 206, show according to the first Pixel Information after the adjustment of pixel.
For each pixel in picture frame to be shown, terminal shows this pixel according to the value of the target R component of the first Pixel Information after the adjustment of this pixel, target G component, target B component, thus demonstrates final picture frame.
Alternatively, in order to realize the Night of different brackets, the look-up table preset in step 203 is at least two, and the brightness level that each look-up table can reduce is different, and the method also comprises step as shown in Figure 3:
In a step 208, ambient light intensity is obtained;
Terminal obtains an ambient light intensity every predetermined time interval, and ambient light intensity refers to the intensity of illumination in the current residing environment of terminal.Alternatively, ambient light intensity is obtained by the preposition light intensity sensor arranged in the terminal.
Disclosure embodiment is not construed as limiting predetermined time interval, is also not construed as limiting the mode obtaining ambient light intensity.
In step 209, environmentally light intensity is from least two look-up tables, determines this look-up table used.
There is corresponding relation between ambient light intensity and look-up table, an ambient light intensity corresponds to a look-up table, but a look-up table can corresponding multiple ambient light intensity.Usually, ambient light intensity is divided into multiple intensity interval, each intensity interval is corresponding with a look-up table.
Terminal, according to the ambient light intensity got, determines that the look-up table corresponding with now ambient light intensity is the look-up table that this uses.
Optionally, the corresponding relation of ambient light intensity and look-up table can be preset by terminal, and also can be set by the user, disclosure embodiment is not construed as limiting this.
Optionally, the look-up table determining that this uses can also manually be selected.
Above-mentioned steps 208 and 209 need complete before step 203, and the execution of disclosure embodiment to step 208 and step 209 is not construed as limiting opportunity.
Based in other embodiment of the embodiment shown in Fig. 2, step 203 replacedly can be embodied as step 203a, as shown in Figure 4:
In step 203, V component is multiplied by pre-determined factor, obtains corresponding target V component.

In step 210, ambient light intensity is obtained;
Terminal obtains an ambient light intensity every predetermined time interval, and ambient light intensity refers to the intensity of illumination in the current residing environment of terminal.Alternatively, ambient light intensity is obtained by the preposition light intensity sensor arranged in the terminal.
Disclosure embodiment is not construed as limiting predetermined time interval, is also not construed as limiting the mode obtaining ambient light intensity.
In step 211, environmentally light intensity is from least two pre-determined factor, determines this pre-determined factor used.
There is corresponding relation between ambient light intensity and pre-determined factor, an ambient light intensity corresponds to a pre-determined factor, but a pre-determined factor can corresponding multiple ambient light intensity.Usually, ambient light intensity is divided into multiple intensity interval, each intensity interval is corresponding with a reservation system.
Terminal, according to the ambient light intensity got, determines that the pre-determined factor corresponding with now ambient light intensity is the pre-determined factor that this uses.
Optionally, the corresponding relation of ambient light intensity and pre-determined factor can be preset by terminal, and also can be set by the user, disclosure embodiment is not construed as limiting this, and the form of disclosure embodiment to corresponding relation is also not construed as limiting.
Optionally, the pre-determined factor determining that this uses can also manually be selected.
