Abstract:
A method and an apparatus for brightness-controlling image conversion. The method includes converting an input image of a first non-linear color space into a second linear color space; determining a brightness control ratio; adjusting channels of the second linear color space according to the brightness control ratio; converting the second linear color space into the first non-linear color space to form an output image.
