Image processing apparatus for applying special effects to image signals

Claim 1

(Amended) An image processing apparatus for applying special effects to input image signals, said apparatus comprising: first signal processor means having first coefficient generator means for generating coefficients K and 1-K (wherein 0≦K≦1), first switch means receiving a plurality of input image signals for selecting first and second image signals therefrom, first and second multiplier means for respectively multiplying said selected first and second image signals by said coefficients K and 1-K, and first adder means for adding output signals of said first and second multiplier means together; second signal processor means having second coefficient generator means for generating coefficients K' and 1-K' (wherein 0≦K'≦1), second switch means receiving said plurality of input image signals and an output signal from said first adder means for selecting third and fourth image signals therefrom, third and fourth multiplier means for respectively multiplying said selected third and fourth image signals by said coefficients K' and 1-K', and second adder means for adding output signals of said third and fourth multiplier means together; generating means for generating first and second key frame data; memory means having a plurality of storage areas for receiving said first and second key frame data from said generating means and for storing said first and second key frame data in respective ones of said storage areas; and control means for controlling said first and second signal processor means on the basis of the first and second key frame data stored in said memory means so as to respectively effect key frame processing thereat.
