Abstract:
An image processing apparatus, comprising:a) an input device adapted to input luminance component data and color component data, which are encoded data and together constitute a color image; b) a decoder adapted to decode the luminance component data and the color component data into data representing a frequency component; c) a dividing unit adapted to separate the luminance component data and the color component data decoded by said decoder; d) a first transforming unit adapted to transform the luminance component data separated by said dividing unit into data representing a pixel value; e) a processor adapted to perform a correction processing on the luminance component data transformed by said first transforming unit; f) a second transforming unit adapted to transform the luminance component data subjected to the correction processing by said processor into data representing the frequency component; and g) an output device adapted to multiplex the luminance component data transformed by said second transforming unit and the color component data separated by said dividing unit, and to output the multiplexed data.
