ABSTRACT:
An original image is converted into a reduced image, based on which a peripheral average luminance image is obtained through a filtering processing. A Retinex image having a smaller size than the original image is obtained from the peripheral average luminance image and the reduced image. The Retinex image is enlarged, and an output image is generated based on the enlarged Retinex image and the original image.
