Abstract
There is provided an image capturing apparatus having an image sensor. A control unit performs control such that image capture by the image sensor is repeatedly performed to generate a plurality of images. A generation unit generates a moving image obtained by arranging the plurality of images in order as a frame. Regarding at least one of the plurality of images, the generation unit repeatedly arranges each image in order as two or more continuous frames. A recording unit records the moving image in association with identification information identifying whether each frame of the moving image corresponds to a same image as an immediately previous frame.
