Abstract
This invention is concerned with systems that create video images. Previously these systems have been limited to ones which create images of television type resolution, however, the systems of this invention may produce an image of higher resolution. The operator draws on a touch tablet and chooses a color and implement type and a line is produced which appears on a screen in approximately real time. At the same time a corresponding line is being produced and written in at high resolution to a large frame store. The high resolution line will be produced at a slower rate than the line to be viewed and so a buffer store is provided for incoming signals. The high resolution image may be read to a print scanner or stored on a disc store.
