ABSTRACT:
Apparatus for displaying an image defined by digital data representing the color content of the pixels of the image comprises a monitor; a first store for storing digital data representing an image at low resolution and a second store for storing digital data representing a magnified portion of the image at high resolution. A microcomputer is connected to the stores and to the monitor and an indicator assembly is acutable by an operator to select an area of an image displayed by the monitor. The microcomputer is responsive to a "magnify" signal from the indicator assembly to cause the monitor to display a portion of the selected after magnification, the portion being displayed within the selected area. The microcomputer suppresses pixels of the orginally displayed image within the remaining portion of the selected area, the degree of magnification being such that the magnified portion substantially fills the selected area.
