Abstract
Apparatus and method for cross-fading moving image signals include structure and steps for temporarily storing moving image signals in a memory for a predetermined period of time. Moving image signals read out from the memory and newly-input moving image signals are continuously combined for an operation time equal to or greater than the predetermined period of time. Thus, it is possible to obtain combined signals such that the moving image signals overlap each other in a relatively simple arrangement without using a special magnetic head.
