An image capturing device includes an image capturing unit capturing an image at a timing based on a first frame rate and outputs data corresponding to the image after a first period, an image data generation unit generating image data based on the output data and outputting the image data after a second period, a display unit displaying a display image based on the image data after the second period and at a timing based on a second frame rate, and a mode selecting unit selecting a first or second mode. The first mode prioritizes reduction in a display delay time. The second mode prioritizes image quality of the display image over reduction in the display delay time. A total period of the first and second periods is less than or equal to a first vertical synchronization period based on the first frame rate when the first mode is selected.
