Latest Patents

Ji Qi holds a patent titled "Rate-control-aware reshaping in HDR imaging." This patent addresses the challenges of mapping an input image in HDR to a second image in a different dynamic range using a reshaping function. The invention allows for the adjustment of the codeword range of the HDR input under specific criteria, particularly for noisy HDR images with a relatively small codeword range. The patent provides an example of generating a scaler that adjusts the HDR codeword range based on the original codeword range and a metric of the percentage of edge points in the HDR image. This adjusted reshaping function enhances rate control during the compression of reshaped images.
