Abstract: Present color TV equipment utilizes single fixation whitebalance color temperature reference programs. Such equipment can not give consideration to various disadvantages in image reproducing results. The method and the apparatus disclosed can correct color TV equipment with a dynamic color temperature state using an applicable range along a Planckian locus color temperature band as a white-balance color temperature parameter region, and can make the corresponding relation between hue - color temperature parameters meet requirements of an optimum image reproducing result. Therefore, the reproducing results and the quality of a general appearance of a color TV picture are improved. It is also possible to produce or improve color TV equipment with low cost.
