1. An image processing system comprising: circuitry configured to store a database in which specific pose data representing a plurality of specific poses of a human, and effect manipulation data specifying a plurality of manipulations applied to an image are registered in association with each other, wherein the database classifies each one of the plurality of specific poses of the human and each one of the associated plurality of manipulations in accordance with a degree of tilt of the specific pose; detect a human region that is a region where a human appears in an image on which to perform image processing; recognize a pose and a degree of tilt of the pose of the human in the detected human region; represent the recognized pose of the human by positions of a plurality of parts in the detected human region of the image; find the specific pose data matching the degree of tilt of the recognized human pose, by referencing the classified degree of tilt of each one of the plurality of specific poses of a human registered in the database, and on the basis of a matching score, the matching score being found from a difference in position obtained for each one of the plurality of parts in the detected human region of the image from a corresponding part in the specific pose data; and apply one or more of the associated plurality of manipulations to the image on the basis of the registered effect manipulation data associated with the matching specific pose data according to the classified degree of tilt.
