To provide an imaging apparatus capable of easily selecting and overlapping appropriate object images corresponding to a moving image being imaged.

On a screen 304s, a moving image Imv is displayed. An effect mode initial image Iem1 which is one of effect execution images is displayed on a part of an area in the screen 304s so as not to cover the entire moving image Imv. When an operation to overlap an object image onto an object image overlapping area in the moving image Imv is made, the object image is overlapped. Even when a setting button Bs is pressed to perform an operation of selecting any one of plural types of object images, a size of the effect execution image is maintained to the size of not covering the entire moving image Imv.
