Embodiment
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, for the present invention, reduce the particular flow sheet of the first embodiment of the method for mobile terminal power consumption.
It is emphasized that: flow chart shown in Fig. 1 is only a preferred embodiment, those skilled in the art is when knowing, any embodiment building around inventive concept should not depart from the scope containing in following technical scheme:
Mobile terminal is determined the gray value of current demonstration image; Mobile terminal is analyzed described definite gray value and whether is greater than the first default gray value; When described definite gray value is greater than the first default gray value, mobile terminal is adjusted the gray value of current demonstration image, so that the gray value of current demonstration image is less than the first default gray value.
Below that the present embodiment is progressively realized the concrete steps that reduce mobile terminal power consumption:
Step S11, mobile terminal is determined the gray value of current demonstration image.
Concrete, the minimum color dot that can reflect image is pixel, and a large amount of pixels is arranged formed set with regard to composing images according to correct rule, and each pixel has corresponding rgb value and half-tone information.Mobile terminal converts the image of current demonstration to the set of each pixel, and determines the gray value of each pixel.In the present embodiment, the gray value of described definite current demonstration image is preferably expressed as the gray value of each pixel in image, and the gray value of the current demonstration image of determining is represented with grey level histogram, can also be also to represent gray value in other modes such as binaryzations; The mean value of the gray value of each pixel in the gray value of the current demonstration image of determining described in other embodiments of the invention also can be expressed as image, or the gray value of partial pixel in image, or the mode of the presentation video gray value that in image, other users such as mean value of the gray value of partial pixel arrange in advance.According to the expression mode of default gradation of image value, determine the gray value of current demonstration image.
Step S12, mobile terminal is analyzed described definite gray value and whether is greater than the first default gray value.
Concrete, the mobile terminal based on AMOLED Display Technique, its darker power consumption of color that shows image is lower, but the color is too dark or too shallowly will bring the distortion of image.Default the first gray value, described the first gray value is less than or equal to the gray value of the too shallow image fault of bringing of color, generally by experience or experiment test, draws, can also be also the gray value of the applicable image of other any users' settings.Mobile terminal is analyzed described definite gray value and whether is greater than the first default gray value.
Step S13, when described definite gray value is greater than the first default gray value, mobile terminal is adjusted the gray value of current demonstration image, so that the gray value of current demonstration image is less than the first default gray value.
Concrete, when described definite gray value is greater than the first default gray value, mobile terminal is adjusted the gray value of current demonstration image, so that the gray value of current demonstration image is less than the first default gray value, and the gray value of the image after adjusting is represented with grey level histogram, to determine whether the gray value of present image is all adjusted under the first default gray value, can also be also to represent gray value in other modes such as binaryzations; When described definite gray value is less than the first default gray value, the gray value of the image representing with grey level histogram is under the first default gray value time, and mobile terminal is not adjusted the gray value of current demonstration image.In other embodiments of the invention, can also be also to comprise step before mobile terminal is adjusted the gray value of current demonstration image: judge that mobile terminal is current whether in battery saving mode, when mobile terminal current during in battery saving mode, mobile terminal is just adjusted the gray value of current demonstration image, so that the gray value of current demonstration image is less than the first default gray value, current during not in battery saving mode at mobile terminal, mobile terminal is not adjusted the gray value of current demonstration image, better to guarantee the display effect of mobile terminal.
By mobile terminal, determine the gray value of current demonstration image; Mobile terminal is analyzed described definite gray value and whether is greater than the first default gray value; When described definite gray value is greater than the first default gray value, mobile terminal is adjusted the gray value of current demonstration image, so that the gray value of current demonstration image is less than the first default gray value.The Image Adjusting that realization shows mobile terminal, to dark colorization, to reduce the power consumption of mobile terminal, extends use and the stand-by time of mobile terminal.
As shown in Figure 2, for the present invention, reduce the particular flow sheet of the second embodiment of the method for mobile terminal power consumption.
Based on above-mentioned the first embodiment, after step S11, comprising:
Step S14, mobile terminal is analyzed described definite gray value and whether is less than the second default gray value, and described the second gray value is less than described the first gray value.
Concrete, default the second gray value, described the second gray value is more than or equal to the gray value of the image fault that the color is too dark brings, and generally by experience or experiment test, draws, can also be also the gray value of the applicable image of other any users' settings.Mobile terminal is analyzed described definite gray value and whether is less than the second default gray value.
Step S15, when described definite gray value is less than the second default gray value, mobile terminal is adjusted the gray value of current demonstration image, so that the gray value of current demonstration image is between the first default gray value and default the second gray value.
Concrete, when described definite gray value is less than the second default gray value, mobile terminal is adjusted the gray value of current demonstration image, so that the gray value of current demonstration image is between the first default gray value and default the second gray value, and the gray value of the image after adjusting is represented with grey level histogram, to determine that the gray value of present image is all adjusted between the first default gray value and default the second gray value, can also be also to represent gray value in other modes such as binaryzations; When described definite gray value is greater than the second default gray value, the gray value of the image representing with grey level histogram is on the second default gray value time, and mobile terminal is not adjusted the gray value of current demonstration image.
By the gray value of current demonstration image being adjusted between the first default gray value and default the second gray value, when guaranteeing the display effect of mobile terminal, better reduce the power consumption of mobile terminal.
As shown in Figure 3, for the present invention, reduce the particular flow sheet of the 3rd embodiment of the method for mobile terminal power consumption.
