A projection system includes a pointing sensing apparatus and a projection apparatus. The pointing sensing apparatus senses at least one of a plurality of instruction signals, and outputs a sensing signal accordingly. The projection apparatus displays a pointing pattern according to the sensing signal. The projection apparatus includes a control module, a first storage module and a second storage module coupled to the control module. The control module receives a plurality of image signals of different formats and generates a plurality of shrink-image data according to the image signals, respectively. The first storage module stores one of the image signals. The second storage module stores the shrink-image data. The projection apparatus displays a normal display image according to contents stored in the first storage module or displays a shrink array image according to contents stored in the second storage module in response to a selecting signal.
