Abstract: Methods and apparatus according to various aspects take as input image data in a lower-dynamic-range (LDR) format and produce as output enhanced image data having a dynamic range greater than that of the input image data (i.e. higher-dynamic range (HDR) image data). In some embodiments, the methods are applied to video data and are performed in real-time (i.e. processing of video frames to enhance the dynamic range of the video frames is completed at least on average at the frame rate of the video signal).
Abstract translation: 根据各方面的方法和装置以较低动态范围(LDR)格式输入图像数据,并产生具有大于输入图像数据的动态范围的输出增强图像数据(即,较高动态范围(HDR) )图像数据)。 在一些实施例中,将这些方法应用于视频数据,并且实时执行(即视频帧的处理以增强视频帧的动态范围至少在视频信号的帧速率下完成)。
