    • A specific target included in an image is detected by a specific target detection unit based on a specific target evaluation value representing likeliness of the specific target. Using a first white balance correction value calculation unit for obtaining a first white balance correction value for the region of the image other than the specific target, a second white balance correction value calculation unit for obtaining a second white balance correction value for the specific target region, and a white balance correction value comparison unit for making a comparison between the first and second white balance correction values, white balance in the region other than the specific target is corrected using the first white balance correction value, and white balance in the specific target region is corrected using the second white balance correction value, if the white balance correction values are different from each other.

    • A noise-reduction apparatus includes an image-noise-reduction means having an operation means and a judgment means. The operation means shifts the level of the signal-value of a target-pixel so that an average of the signal-values of the target-pixel and pixels in a predetermined area in the vicinity of the target-pixel becomes a value at the origin of a color-space of each of a plurality of color-components, performs an operation for noise-reduction processing on the target-pixel and restores the level of the signal-value thereof based on the shifted level. The judgment means estimates a noise-amount of the target-pixel, calculates a statistic representing the noise of the target-pixel based on the signal-values of the target-pixel and the pixels in the predetermined area, compares the estimated noise-amount and the statistic, and determines, based on the result of comparison, which of the estimated noise-amount and the statistic to use for the operation of noise-reduction processing.
