Image converting apparatus and image converting method
 An image converting apparatus for converting an image of an input video signal into an image with a metallic luster and representing the metallic luster with parameters designated corresponding to the input image. The apparatus is based on the concept that a model of reflected light can represented with a model of reflected light of diffusion reflection and mirror-surface reflection and that even though the resultant model of reflected light is three-dimensional data, assuming that the brightness of an input video signal linearly varies, the model can be represented with brightness data. A color correction circuit 5 has a look-up table with which calculations for generating an image with a metallic luster are performed with the brightness data and the designated parameters. A matrix calculating circuit extracts a luminous signal component from the input video signal. A pre-modifying circuit adjusts the amplitude. The color correction circuit performs calculations for generating an image with a metallic luster. Mix circuits mix output signals of the color correction circuit with an input video signal.
