Claim:
A method comprising: receiving an image containing a representation of a person's face, where the face has a target feature, wherein the image has points each including a Cb component and a Cr component in a YCbCr space; for each of the points of the image, combining, by a system having a processor, values of the Cb and Cr components to provide an aggregate value for the corresponding point, wherein combining the values comprises calculating a product based on the Cb and Cr components; lightening midtones of values of a Y component in the YCbCr space to provide pre-processed values of the Y component; darkening midtones of the aggregate values derived from calculating the product based on the Cb and Cr components to provide pre-processed aggregate values; combining the pre-processed values of the Y component with the pre-processed aggregate values; and producing a converted image based on values for the corresponding points derived from combining the pre-processed values of the Y component and the pre-processed aggregate values.
