Image processing system with external storage of special effect data

DETAILED DESCRIPTION What is claimed is: 1.
An image processing system for applying a video special effect to input image data, comprising: a memory for storing image processing data; coefficient generator means for generating coefficients on the basis of the image processing data stored in said memory; signal processor means for processing the input image data on the basis of the coefficients generated by said coefficient generator means; switch means for selectively supplying the input image data to the signal processor means from at least one of a plurality of sources of image data; control means for controlling operation of said switch means; said control means also being connected for data communication with said memory; and external storage means for storing plural kinds of image processing data; said control means being connected for data communication with said external storage means and controlling said external storage means and said memory so as to transfer at least a desired one of said plural kinds of image processing data to said memory from said external storage means.
2.
The image processing system according to claim 1, wherein said external storage means includes a hard disk for storing said plural kinds of image processing data.
3.
The image processing system according to claim 1, wherein said external storage means includes a hard disk for storing said plural kinds of image processing data, and an operation computer for forming said plural kinds of image processing data.
4.
The image processing system according to claim 1, wherein said memory includes a first memory unit for storing color data, a second memory unit for storing data representing an image, and a third memory unit for storing pattern data; said plurality of sources of image data include a video camera, a VTR, said first memory unit, and said second memory unit; and said signal processor means includes multiplier means for multiplying by said coefficients the input image data supplied by said switch means
