To efficiently execute correction of pixel values of a motion-presence area of captured image data. In correction processing for pixel values of a particular area such as a motion-presence area, initial values of the differences or ratios between white balance adjusted image data and flash image data are set, and conversion of the initial values is performed in accordance with a smoothing filter or a conversion expression whose weight is set on the basis of flash image data, and estimated values of image differences or image ratios in the motion-presence area are calculated to apply the estimated values to execute pixel value correction of the motion-presence area. In addition, after white balance adjustment using a low resolution image and pixel value correction of the motion-presence section, a high resolution corrected image is generated on the basis of the correspondence of a corrected image to low resolution image data.
