The present invention relates to an image processing apparatus, an image processing method, and a program that are capable of removing an influence due to illumination components from a plurality of images in which illumination environments are different and generating an image having high color reproducibility. A demosaic processing unit 221 performs a demosaic process on a reference image held in a reference mosaic image holding unit 111. A demosaic processing unit 222 performs a demosaic process on a processing target image that is held in a processing target mosaic image holding unit 112. A white balance calculation unit 230 calculates a white-balance value for each channel with respect to the reference image. A channel gain calculation unit 250 calculates a gain for each channel for converting illumination components on the basis of RGB values of the reference image and the processing target image, and the white balance of the reference image. At the time of gain calculation, blackout condition, saturation, and the like are considered. A channel gain application unit 260 applies the gain calculated by the channel gain calculation unit 250 to each channel of the processing target image.
