Abstract
The processor obtains a third pixel value and a second pixel value of the display. The processor determines a desired pixel value range that exceeds the second pixel value of the display. The processor obtains a threshold between the third pixel value of the display and the second pixel value of the display. The processor obtains a function mapping the desired pixel value range to a range between the threshold and the second pixel value. The processor applies the first function to an input image prior to displaying the input image on the display. The display presents the image. Upon recording the presented image, the processor determines a region within the recorded image having a pixel value between the threshold and the second pixel value. The processor increases dynamic range of the recorded image by applying an inverse of the function to the pixel value of the region.
