ABSTRACT:
An illumination component extractor is operable to extract an illumination component from input image data by: performing a smoothing process a certain number of times to generate a plurality of smooth image data having resolutions different from one another from the input image data, the smoothing process including an operation of filtering the input image data with use of a low-pass filter having a predetermined size and an operation of downsampling the filtered input image data; and performing an inverse-smoothing process a certain number of times, the inverse-smoothing process including an operation of replacing an edge portion of a smooth image data having a lower resolution with a smooth image data having a higher resolution, and an operation of upsampling the replaced smooth image data. The input image data is color image data which has been obtained by an image sensor including a number of pixels having different spectral sensitivities.
