Image generation device, imaging device, image generation method, and program

An image generating device comprising:

• a human detector that detects a human from a captured image;
• a motion detector that identifies a motion between frames from the captured image, each of the frames being a unit of an image;
• a cut-out frame deciding unit that decides a cut-out frame for cutting out a new image from the detected human and the identified motion based on a constraint condition regarding a camerawork between the frames;
• and
• a composition information shaping unit that cuts out the new image from the captured image by using the cut-out frame, and converts a size of the new image to a predetermined size.

An image generating method comprising:

A program for enabling a computer to perform:

• detecting a human from a captured image;
• identifying a motion between frames from the captured image, each of the frames being a unit of an image;
• deciding a cut-out frame for cutting out a new image from the detected human and the identified motion based on a constraint condition regarding a camerawork between the frames;
• and
• cutting out the new image from the captured image by using the cut-out frame, and converting a size of the new image to a predetermined size.
