Digital video effects created from spatial frequency banded frames

Apparatus for creating digital video effects on a first original frame of original image data containing pixel values, said apparatus comprising

• a frequency transformer that receives said first frame of said original image data and creates first spatial frequency banded frames from said first frame of original image data, each said spatial frequency banded frame containing pixels having pixel values defining an image of a spatial frequency band of said original image data,
• a filter that receives said first spatial frequency banded frames and selectively processes at least some of said first spatial frequency banded frames to different extents, the pixel values of all pixels in each first spatial frequency banded frame being adjusted to the same extent, said filter outputting processed first spatial frequency banded frames for different spatial frequency bands, and
• a synthesizer that combines said processed spatial frequency banded frames for different spatial frequency bands and outputs a processed frame having an image that is modified with respect to said original image data.
