Abstract
Some embodiments of the invention provide novel methods for converting the color region of images. For instance, the method of some embodiments converts the color of an image from one color region (e.g., from a Rec. 601 color region) to another color region (e.g., to a Rec. 709 color region). In some embodiments, the method receives the image in a first color format that is non-linearly encoded within a first color region. Without performing a linearization operation to linearize the color component values of the image, the method then converts the image into a second color format that is defined with respect to a second color region. In some embodiments, the color-converted image is non-linearly encoded in the second color region.
