Abstract
A processing of pixels comprises checking whether a color component of a pixel in a color space resulting in a smallest error between at least one color component in another color space determined based on the color component and at least one original color component of the pixel in the another color space causes any color channel of the pixel to fall outside of an allowed range. A value of the color component is obtained using a first function/LUT if the color component resulting in the smallest error does not cause any color channel of the pixel to fall outside of said allowed range. However, a value of the color component is obtained using a second, different function/LUT if the color component resulting in the smallest error causes any color channel of the pixel to fall outside of the allowed range.
