Abstract
In a first filtering processing step, RAW data of a source image is subjected to a pixel-based filtering process along a first array direction to divide the RAW data into a first luminance data and a first color carrier data. In a first luminance distribution equalization processing step, the luminance distribution of the first luminance data in the first array direction is corrected to be uniform to produce a second luminance data. In a first color array reproduction processing step, the first color carrier data is re-synthesized with the second luminance data to produce a first multiple-color array data. In a second filtering processing step, the first multiple-color array data is subjected to a pixel-based filtering process along a second array direction to divide the first multiple-color array data into a third luminance data and a second color carrier data. In a second luminance distribution equalization processing step, the luminance distribution of the third luminance data in the second array direction is corrected to be uniform to produce a fourth luminance data. In a second color array reproduction processing step, the second color carrier data is re-synthesized with the fourth luminance data to produce a second multiple-color array data.
