Abstract
A video image alteration apparatus is described that separates the vertical and horizontal aspects of image alteration. Pixels relating to an input image derived from a frame of film are sampled at a predetermined rate related to a film scanning speed and a television line standard, and the flow of pixel information is coordinated through a memory section by write control and read control signals. A frame store, which stores image pixel data corresponding to at least one film frame, includes a line output and address inputs for selecting a line start position and a line advance increment. To obtain the aforementioned spatial separation, a line store, which is responsive to the line output of the frame store for storing at least one line of image pixel data, includes a pixel output and address inputs for selecting a pixel start position and a pixel advance increment. Lines and pixels are repeated as necessary for zoom and pan effects by appropriately addressing the frame store for vertical repeats and the line store for horizontal repeats. New image pixels are then generated by a spatial interpolator responsive to the pixel output of the line store.
