  • Image processing method and image processing apparatus for obtaining overlaid image
    Patent number: 7071953
    Abstract: Two images P1 and P2 having different backgrounds are input into a transparency calculation processing part AT. The transparency calculation processing part AT obtains a transparency image PT from P1 and P2. Next, noise is removed from the transparency image PT as necessary. A color calculation processing part AC generates a color image PC from P1 and P2. Next, a cutting processing part AR cuts unnecessary parts from the transparency image PT and the color image PC. Finally, an overlaying processing part AS overlays the object O on a background image PZ by using PT, PC and PZ.
