Abstract
In a special effects video processor, a low-pass filter limits, in a horizontal direction, the bandwidth of an input video signal. A field/frame converter, receiving the video signal from the first low-pass filter, generates a frame signal which is comprised of a video signal for one frame by generating one odd or even field signal from the other said odd or even field signal. A low-pass filter limits in a vertical direction the bandwidth of such frame signal supplied from the field/frame converter. In a mapping processor, a memory stores the frame signal supplied from the second low-pass filter, and an interpolator performs interpolation for a plurality of data in the frame signal read from the memory. Such special effects video processor provides a processed video image without deterioration in quality.
