PURPOSE:To enable subject screen images to be independently and optionally scrolled and controlled on a screen by sequentially generating the subject screen image information for a plurality of screens including at least one subject image in each screen via a subject image information generation circuit. CONSTITUTION:A subject image information generation circuit 10 outputs subject image information for one screen corresponding to each of a plurality of subject images obtained from a subject data RAM 12, and stores the subject images for a plurality of screens superposed in space corresponding to a single screen. The output of the subject image information generation circuit 10 is equivalent to the superposition of a plurality of screen images, each including at least one subject image. In addition, respective images on a screen are independently scrolled and treated, separately from other screen images. Consequently, each subject is independently scrolled on the screen. |
