Abstract
Techniques for performing panoramic scaling are disclosed that reduce visible distortion in a panoramic image. Further, techniques for performing combined YC adjustment and color conversion are disclosed that reduce the size and power requirements of video manipulation hardware by reducing the number of logic gates and memory buffers required when YC adjustment and color conversion are implemented as separate operations.
