  • Video graphics systems separately processing an area of the picture before blending the processed area into the original picture
    Patent number: 5276786
    Abstract: A video graphics system in which an effect can be produced in selected portions of a image held in a first store. Image data in the first store relating to a user defined area of interest in the image is copied to a second store and processed in accordance with a user selected function. The area of interest is selected by the user by magnifying and shifting a displayed representation of the image so that the area of interest is displayed and then selecting a locking function which retains parameters associated with the shifting and magnifying of the displayed image. Once the image data relating to the area of interest has been processed it can be painted onto the image held in the first store to produce the desired effect. By processing only the selected area of interest the speed of processing is increased.
