Brightness historical data in border includes 3 data, then according to the 3 of the integrated environment luminance information and the ambient brightness historical data
A data determine that screen it is expected brightness, for example, can be by the integrated environment luminance information and the ambient brightness historical data
3 data average value as screen it is expected brightness.
In the present embodiment, luminance weights value can be system default setting value, or user setting value.Citing comes
It says, according to chronological order, the environmental history data include N1, N2, N3, the integrated environment luminance information L1, difference
For N1, N2, N3 and L1, W1, W2, W3, W4 are set, wherein W1 < W2 < W3 < W4, according to formula P=N1*W1+N2*W2+N3*W3+
L1*W4 calculates the first ranking operation result, wherein P indicates the first ranking operation result.Using the value of P as the screen of mobile terminal
Curtain expectation brightness.
In this way, the variation tendency of the ambient brightness in a period of time can be fully considered, determines under the situation of presence and be suitable for
Screen it is expected brightness, improves the accuracy of screen expectation brightness.
