Abstract
The present disclosure relates to a shooting device, a shooting method, and a program capable of suppressing shooting of an image including large blurring due to motion of a camera such that an image with less blurring may be shot. The camera motion is detected, a distribution degree of a trajectory of the camera motion based on a camera motion detection result is calculated to be compared with a predetermined threshold, and start and finish of exposure is controlled on the basis of a comparison result. The present disclosure may be applied to the shooting device.
