ABSTRACT:
A white balance coefficient setting unit 51 sets a white balance coefficient for an image signal; a white balance correction coefficient determination unit 52 determines two white balance correction coefficients to be applied to a luminance signal of the image signal in accordance with the white balance coefficient; a luminance signal operation unit 59 obtains two output signals by multiplying the luminance signal by each of the two white balance correction coefficients; a first adder 57 adds one of the two output signals and a first color difference signal of the image signal together; a second adder 58 adds the other output signal and a second color difference signal of the image signal together. Adding results of the first and the second adders 58 and 59 will be output as a white balance correction value to be applied to the two color difference signals.
