An imaging element includes a memory that stores first image data obtained by being captured by the imaging element and is incorporated in the imaging element, and a first processor that is configured to perform image data processing on the first image data and is incorporated in the imaging element. The first processor is configured to receive vibration information related to a vibration exerted on the imaging element within a frame output period defined by a first frame rate, and output second image data obtained by assigning the vibration information to a specific position set in the first image data within the frame output period.
