Description
Technical field
The invention belongs to the multimedia technology field of image procossing, and in particular to a kind of mobile terminal based on OLED screen curtain
The energy consumption optimization method of navigation application.
Background technology
The development of the Internet, applications technology drives the development of mobile terminal device with popularization.Terminal device has been not to pass
The instrument for making a phone call to send short messages in system meaning, but the distance problem in people and the information-based world.People are connect by mobile device
Entering internet carries out acquisition of information, is exchanged with people, enjoys the breath of information age.However, the power consumption of mobile device is asked
Topic is gradual to cause extensive concern.In the application process of mobile device, the power consumption of the screen of mobile terminal occupies overall
The very big share of power consumption, the power consumption optimization of screen seems very meaningful.Experimental number is it has been found that screen display
Power consumption needed for the image of different colours structure is different.
The Main way for solving the problems, such as power consumption is not influence the visual effect of people or improving the situation of visual contrast
Under, the color combination to image is reconstructed, and original image color is entered by choosing power consumption smaller colour sequential
Row is replaced, and the purpose of color power consumption is reduced so as to reach.Using specific to Lab color spaces between property, i.e. corresponding color
Euclidean distance it is equal in the case of the visible sensation distance that gives people be equal to measure the color of image property after reconstruct and original
The visual effect that color of image property is brought.
Understand by inquiry, the mobile terminal screen of main flow is LCD and OLED on the market.Traditional lcd screen：LCD is
Light source is provided by backlight, the display of picture material is then realized by polaroid.By reducing the bright of LCD backlight
Spend to realize that low-power consumption is most straightforward approach, influence of the different tones to color is not apparent.So being directed to LCD
For the screen of class, the optimization direction of power consumption should ensure visual effect, reduce brightness.New technology OLED screen curtain：OLED screen
Curtain enjoys mobile terminal manufacturer to be favored according to definition and the small advantage of power consumption.From unlike traditional LCD class screens,
OLED screen curtain is that each pixel independently lights without backlight.Each pixel of OLED has Red, Green,
Tri- kinds of luminous points of color component of Blue can independently be lighted, and the different color forms of expression are combined into according to different ratios.
Therefore, the power consumption optimization direction for OLED screen curtain is to combine brightness of image and picture tone structure（The main object of optimization）.
Experiment can be obtained, and required power consumption is different during the different color of screen display.Such as：The power consumption of the Blue components of same levels
More than Green components.
For mobile terminal device main flow screen application analysis currently on the market, come to mobile terminal from a new angle
Power consumption optimize, jumped out traditional by expanding battery capacity mode.It is true feasible, is adapted to movement
The application development trend of terminal screen enlarging.
In mobile phone carries out navigation application, it be greatly from OLED screen curtain that the power consumption consumption of mobile phone screen has
Work.So the optimization to the power consumption performance of screen is very to be necessary, and moreover, can also be by the control of tone
Navigation map to generate different tones can be good at meeting different Man's Demands.

Power consumption needed for terminal screen display image is estimated.
Part II：Optimization navigation map
2-1, acquisition priming color table.
There is provided by designer or obtain final color table by intercepting some images.
2-2, color power consumption calculation.
The power consumption sequence of color classification is carried out to the priming color table being input into according to the estimation of image power consumption；Using defeated
Respectively classification initializes default sized images to the color of the priming color table for entering respectively, and then the whole power consumption to image is estimated
Calculate, the final power consumption sequence for obtaining color classification.
2-3, the adjustment of harmony degree.
According to classical color harmony topology degree, learn by way of machine learning in database is carried out to color table
Harmonious degree evaluation method, for ensureing that the color of image effect after color table transform meets the visual effect of human eye.
2-4, hue adjustment.
By being input into some images liked, the mode for using K-means to cluster extracts the dominant hue of image for being face
Color reconstruct provides tone selection reference.
2-5, color reconstruct.
The power consumption parameter of color combining, hue adjustment parameter and harmony degree adjusting parameter are done with reference to adjustment by setting ratio.
Beneficial effects of the present invention：The present invention reconstructs and face the color of the power consumption property of OLED screen curtain, different tones
Color harmony degree balancing method combines, and is applied to the typical power consumption application-Mobile Telephone Gps of mobile terminal based on OLED screen curtain
Using.Not only there is strong theory support, and can simultaneously meet reduction and the diversified demand of tone of energy consumption.
Optimization application shows two aspects：1st, the color table after using reconstruct in the design process of navigation map is to original
Beginning color table carries out color replacement；2nd, optimize funtion part during the use of navigation software as a power consumption, use
Image processing techniques is reconstructed in real time to the color of image.
