Tone mapping is first applied to the input image to map the colors, to find an optimized range of brightness values, and to scale the color to place colors inside the optimized range (in-range colors) into a device color space (e.g. sRGB), but without clipping colors outside of the optimized range (out-of-range colors). The scaled colors are then converted to the color space of the output device (e.g. CMYK) using WCS (Windows Color System) color transform, where the in-range colors are processed using a optimized transform and the out-of-range are processed using a sequential transform. A mapping from the original color space to the converted color space for all colors in the image is stored in a lookup table (LUT), and the input image is converted to the output image using the LUT."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for processing high dynamic range images using tone mapping and WCS color transforms","description":"A method for processing a high dynamic range (HDR) image for printing.
