Image processing apparatus which does not generate a false signal even if unevenness of spectral sensitivities of the color filter occurs

摘要

An apparatus for processing image data including three complementary color components representing the three primary colors includes a distribution circuit for distributing the image data into first to third complementary color components. A multiplication circuit generates first to third products by multiplying the first and second complementary color components, the first and third complementary color components, and the second and third complementary color components. A square root circuit then calculates the square root of each of the three products. The calculated square roots represent the three primary colors.
