Abstract
Disclosed here are various techniques to increase dynamic range of an image recorded from a display. A processor performing preprocessing splits an input image containing both bright and dark regions into two images, image A containing bright regions, and image B containing dark regions. The display presents image A and image B in alternating fashion. Camera is synchronized with the display to record image A and image B independently. In postprocessing, a processor obtains the recorded images A and B. The processor increases the pixel value of the recorded image A to obtain image A with increased pixel value. Finally, the processor increases pixel value of the image recorded from the display by combining the first recorded image with increased pixel value and the second recorded image.
