ABSTRACT:
A video image creation system provides intensity or color data from one or more stores. The image is created under manual control which effectively defines the coordinates of the artists implement at any given time.
A processor receives the incoming image data and previously derived data from a frame store and modifies this data in dependance on a parameter available from another store. The created image can be viewed on a monitor.
The parameter controls the contribution made from any adjacent, previously created, parts of the image and can be such as to simulate different pencil or brush shapes or types of paint for example. Additional facilities such as pressure sensitivity and blurring can be provided.
