An image capturing device includes an image capturing section that captures first video data having a frame cycle of a first frame cycle and an exposure time for one frame shorter than the first frame cycle, an image acquisition section that acquires the first video data captured by the image capturing section, a detection section that detects a flicker of a light source in the first video data, and an image capturing frame cycle control section that controls the frame cycle of the image capturing in the image capturing section. The image capturing frame cycle control section changes the frame cycle of the first video data captured by the image capturing section from the first frame cycle to a second frame cycle, which is a frame cycle shorter than the first frame cycle, in a case where the detection section detects the flicker.
