Abstract

This paper proposes the power constrained contrast enhancement algorithm for OLED display based on the multi-mapping functions for improving the local contrast of the input image. The proposed method divides the input image into several blocks. Then, it calculates the multi-mapping functions corresponding to each block using convex optimization process between the image quality and power consumption. Using the multi-mapping function, the proposed method adjusts the mapping function and calculates the output image using the bilinear interpolation. In the experimental results, the proposed method improved the local contrast, and increased the enhancement performance measure and sharpness by up to 57.8% and 41.9% compared to benchmark methods.
利用多映射功能增强OLED显示屏的对比度,降低功耗
为了提高输入图像的局部对比度,提出了一种基于多映射函数的功率约束OLED显示器对比度增强算法。该方法将输入图像分成若干块。然后,利用图像质量和功耗之间的凸优化过程,计算出每个块对应的多映射函数;该方法利用多重映射函数对映射函数进行调整,并利用双线性插值计算输出图像。实验结果表明,该方法提高了局部对比度,增强性能指标和锐度分别比基准方法提高了57.8%和41.9%。
