Abstract
A method and a device for automatic color correction by defining an operation window, a target window, and an active region bounded by the preceding windows so as to adjust chroma values in the active region. Correction of chroma signals is associated with a window region rather than a certain point. Besides, the present invention provides correction of the chroma signals so as to prevent image discontinuity and disharmony.
