Abstract
A peripheral blown-out pixel counter counts the number of blown-out pixels in a block including a target pixel and peripheral pixels in image data. A G threshold setting unit sets a G threshold such that the G threshold is greater as the number of the blown-out pixels is larger. A (B−G) threshold setting unit sets a (B−G) threshold such that the (B−G) threshold is smaller as the number of the blown-out pixels is larger. A correction necessity determination unit determines that a color of the target pixel should be corrected when a G signal is determined to be smaller than the G threshold and a (B−G) value is determined to be greater than the (B−G) threshold. A color correction unit corrects at least the G signal and a B signal when the color of the target pixel should be corrected.
