Abstract: To provide an image capturing apparatus capable of suppressing a delay in a transition from an event detection state in which a frame rate is reduced to a normal photographing state in which a recording image is imaged.SOLUTION: Included are an imaging element, a controlling unit, a first detection unit, and a second detection unit. The imaging element has a plurality of pixels two-dimensionally arranged. The controlling unit switches between a normal photographing mode in which pixel signals are read from the imaging element to generate image data for photographing, and a plurality of types of detection modes in which the pixel signals are read from the imaging element by reducing the amount of signals compared with normal photographing mode to detect change of a subject on the basis of the read signals. The first detection unit detects the change of the subject in the plurality of types of detection modes.
