A central processing unit (CPU) is coupled to a random access memory (RAM) which is organized in correspondence with a cathode ray tube (CRT) type display. The to-be-displayed image is sequentially read from the RAM by a character reader. A reference clock system provides appropriate timing and synchronization signals for CRT scan and memory read out. Means are provided for altering the timing between CRT scan and memory read out in an erratic or psuedo-random manner to produce a scene-shaking effect in the displayed image. |
