<p>PROBLEM TO BE SOLVED: To stop an image effect at an optional position or to resume the image effect from the stopped position by managing a change from a start point of time of the image effect such as wipe, scroll, and dissolve. SOLUTION: An execution instruction generated from a system control circuit 2 is set to an image effect control circuit 4. After the image effect is started, the image effect is stopped by an image effect stop signal from the system control circuit 2 and a change in the image effect for that time (e.g. a moving amount) is calculated by a change amount calculation circuit 5 and the system control circuit 2 monitors the value.</p> |
