1. An image capturing apparatus comprising: an obtaining unit configured to sequentially obtain images obtained by image capturing of a subject; and a generation unit configured to combine a plurality of images obtained by said obtaining unit and generate a moving image including an obtained composite image as a frame, wherein if the plurality of images differ in angle of view at the time of image capturing, said generation unit changes the plurality of images into images having the same angle of view by adjusting angles of view of images which differ in angle of view from one reference image of the plurality of images, and combines the images, and whether the plurality of images differ in angle of view at the time of image capturing is detected by detecting whether zooming operation has been performed during image capturing of the plurality of images.
