Latest Patents

Uehara holds a patent for a method titled "Method for recovering highlights and saturated regions and extending dynamic range in a digital image." This method involves analyzing pixels in an image and compensating for identified highlights and saturated pixels. The process ensures that each color channel in a pixel is highly correlated, allowing for effective recovery through a combination of other channels. Specifically, a pixel is deemed restorable if at least two of its color channels are not saturated. The method generates replacement pixel values based on the correlation of color channels, enhancing the overall dynamic range of the image.
