摘要: A method of estimating shift white balance point. According to characteristics a photograph sensing apparatus, white-point plane YIQ color coordinate is determined. The has normal direction pointing one the axis coordinate. thus perpendicular such with one-dimensional one-spot value. Consequently, image data described by obtained. same rotation operation performed rotate obtain value compared differential value, so as estimate shift. In above method, includes Y-axis after rotation.
