Abstract
A television special effects generator operating on digitally encoded video signals is disclosed. The generator includes a frame store, input addressor and output addressor. The input addressor means is controlled to write picture information into the frame store in a desired manner while the output addressor includes an up/down counter whose count direction can be reversed when a given count is reached. By reversing the up/down counter count direction part way through a line or field scan, the displayed picture appears in two parts, one being the mirror image of the other.
