An image projection control apparatus is connected to a plurality of data processors for generating image data, and displays a plurality of images projected onto a screen by a display unit based on the image data generated by the data processors. The image projection control apparatus includes an image controller for editing the image data supplied from the data processors and for outputting the edited image data to the display unit, and an image manipulator for controlling the image control means and the data processors. The image manipulator has a pointing device for displaying a pointer movably on a screen image on the screen and selecting a command indicated by the pointer for execution, a data processor selector for selecting one of the data processors which generates the image data corresponding to the image where the pointer is presently positioned, and an execution instructing unit for instructing the selected data processor to execute the indicated command.
