| Abstract: | To adjust the color hue, it is usually to compute the LHS components from the RGB color image, where only the H component is adjusted, and then the RGB components are computed form the adjusted H and unprocessed L and S components. However, to convert LHS space to RGB space is not easy. A simple method to adjust the color hue component is proposed. Some simplifications have been made and no more color space transform and inverse transform are needed. In the equations derived, there are simply arithmetic operations, and the computations are easy with also quick computing speed. Error analysis is given and it is shown that the results obtained are quite acceptable in practice. |
