Terminal device and control method

摘要

It is an object of the present invention to provide a photograph-taking terminal device that offers users improved convenience. The terminal device includes a face detection unit configured to detect human faces in image consecutively generated by photography, a focusing mechanism configured to focus for photography, and a control unit configured to control the focusing mechanism. After the face detection unit begins detection operations, the first time a face is detected, the control unit instructs the focusing mechanism to focus. After focusing, the control unit prevents the focusing mechanism from focusing again until the face detection unit no longer detects any face. After a face is detected anew, the control unit instructs the focusing mechanism to focus again.

1. A terminal device comprising:
a face detection unit configured to detect one or more human faces in a field of view of a camera; a focusing mechanism configured to focus on the detected one or more human faces; a control unit configured to, when the face detection unit detects the one or more human faces after a state in which no human face is detected,
instruct the focusing mechanism to focus based on the detected one or more human faces, and,after completion of the focusing based on the detected one or more human faces, prevent the focusing mechanism from refocusing for as long as the face detection unit detects at least one human face, regardless of whether one or more of the detected one or more human faces change position with respect to the field of view, and allow the focusing mechanism to refocus if the face detection unit no longer detects at least one human face.
