There is disclosed a method of displaying a visual image, such as a digital image, on a display surface (10), such as a screen or wall, using a video projector (12). The total area occupied by the complete visual image on the display surface (10) is larger than the area of the projected image (14) produced by the video projector (12). The method comprises determining the location (14a,14b) on the display surface (10) of the projected image produced by the video projector (12). Subsequently,a part of the complete visual image is selected which corresponds in position within the visual image to the location of the projected image (14a,14b) on the display surface (10). The image part is displayed as the projected image (14a,14b). The method has the advantage that all of the projected image (14) can be used to display the visual image, in parts. The video projector (12) can be moved to display any desired region of the complete visual image. |
