Abstract
Various embodiments of the present technology comprise a method and apparatus for high dynamic range imaging. According to various embodiments, the method and apparatus for high dynamic range imaging is configured to select the “best” signal for each pixel location to construct an HDR output. In one embodiment, the “best” signal is select among various pixel signals and the pixel signal selected as the “best” signal is based on the value of the pixel signals and identification of non-saturated. If only one pixel value for a particular pixel location is non-saturated, then the “best” signal is the non-saturated signal. If more than one pixel value is non-saturated, then the “best” signal is the pixel signal with the greatest value. If two more pixel values are non-saturated and both have equally great values, then the “best” signal is the pixel signal with the shortest integration time.
