First Claim
1. A region detection device comprising:
- at least one processor configured to;
extract a plurality of frames of still image data from moving image data,detect an attention person, who is a person to be processed, from a plurality of still images corresponding to the plurality of frames of still image data,track a movement of the attention person in a moving image corresponding to the moving image data, on the basis of the detection result of the attention person in the plurality of still images, and detect a movement trajectory of the attention person,analyze a motion of the attention person in the moving image, on the basis of the movement trajectory of the attention person, and calculate an evaluation value for the motion of the attention person in each of the plurality of still images, on the basis of the analyzed motion of the attention person,output the still image data of a still image in which the evaluation value for the motion of the attention person is equal to or greater than a threshold value from the plurality of frames of still image data,detect an attention person movement region of the moving image captured in the still image in which the evaluation value is equal to or greater than the threshold value, on the basis of the movement trajectory of the attention person,detect a face region of the attention person in the still image in which the evaluation value is equal to or greater than the threshold value, anddetect an entire region of the attention person in the still image in which the evaluation value is equal to or greater than the threshold value, on the basis of the attention person movement region of the moving image and the face region of the attention person.

Abstract
The image processing apparatus includes a region detection unit that detects a face region of the attention person, an attention person movement region of the moving image, the entire region of the attention person, and an attention person transfer region of the moving image, a region image extraction unit that extracts an image of the face region of the attention person, an image of the attention person movement region of the moving image, an image of the entire region of the attention person, and an image of the attention person transfer region of the moving image, which respectively correspond to the face region of the attention person, the attention person movement region of the moving image, the entire region of the attention person, and the attention person transfer region of the moving image, from the still image, and a composite image generation unit that generates a composite image.
