Abstract: In order to solve the problem that the high power consumption of mobile terminal screen affects the endurance ability,a color table generation strategy for defining the visual distance is proposed and applied to the color reconstruction of the image.The main strategy is to generate a color table defined by color visual distance based on the given parameters,which is the initial value of luminance and color distance.The color reconstruction of the image is to replace the energy-consuming color structure of the image with the low energy consumption color combination according to the difference of energy consumption required by the different colors displayed on the screen.This paper selects the mainstream mobile terminal as the experimental equipment to obtain the original power consumption data of the screen.By fitting the measured power consumption data,a power consumption evaluation model is built to verify the influence of different color structure images on the power consumption of mobile devices with organic light-emitting diode screens.On this basis,the color of the image is reconstructed to optimize the power consumption of the screen to display the image,which can be widely used in mobile navigation maps and so on.The experimental results show that the proposed image reconstruction strategy saves about 35% of the energy consumption of the screen image,and the structural similarity of the image before and after reconstruction is about 95%.
