Abstract
In one embodiment, there is provided a video processor. The video processor includes: a storage configured to store characteristic data of a display; a generator configured to generate target tristimulus values based on the characteristic data and a luminance value at a first gradation level and to generate correction values based on the target tristimulus values; and a processor configured to correct a color temperature of at least an interval between a high-gradation portion and a low-gradation portion based on the correction values.
