PORTABLE SUSPICIOUS INDIVIDUAL DETECTION APPARATUS, SUSPICIOUS INDIVIDUAL DETECTION METHOD, AND COMPUTER-READABLE MEDIUM
First Claim
1. A portable suspicious individual detection apparatus comprising:
- a wearable image pick-up device to be put on a body of a user;
a face detecting device which detects a human face region from subject images successively taken by the image pick-up device detects;
an eye-gaze direction detecting device which detects an eye-gaze direction of a person with the detected human face region;
a sight determining device which determines whether or not the person with the detected human face region is looking at the user, based on the eye-gaze direction detected by the eye-gaze direction detecting device;
a time period detecting device which detects an amount of time during which the person with the detected human face region is looking at the user when the sight determining device determines that the person with the detected human face region is looking at the user;
a suspicious individual determining device which determines that the person with the detected human face region is a suspicious individual when the amount of time detected by the time period detecting device is a predetermined amount of time or more; and
a notification device which provides the user with information indicating the detection of the suspicious individual when the suspicious individual determining device determines that the person with the detected human face region is the suspicious individual.

Abstract
Cameras provided to glasses successively take subject images around a wearer of the glasses. The subject images are searched to detect human face regions, and if human face regions are detected, feature quantities of each face are calculated to detect the face direction and the eye direction, and an eye-gaze direction is detected based on them. Whether or not each person with the detected human face region is looking at the cameras is determined from the eye-gaze direction, and if there is a human face looking at the cameras for a given period of time or more, a person with the human face is determined as being a suspicious individual, and a warning message indicating the detection of the suspicious individual is output to the wearer. Furthermore, the detection information and images can be provided to a device in a remote location.

14. A suspicious individual detection method comprising:
-
an image taking step for successively taking subject images using a wearable image pick-up device; a face detecting step for detecting a human face region from the successively-taken subject images; an eye-gaze direction detecting step for detecting an eye-gaze direction of a person with the detected human face region; a sight determining step for determining whether or not the person with the detected human face region is looking at a user of the wearable image pick-up device, based on the detected eye-gaze direction; a time period detecting step for detecting an amount of time during which the person with the detected human face region is looking at the user when it is determined that the person with the detected human face region is looking at the user at the sight determining step; a suspicious individual determining step for determining whether or not the person with the detected human face region is a suspicious individual based on the detected amount of time; and a notification step for providing the user with information indicating the detection of the suspicious individual when it is determined that the person with the detected human face region is a suspicious individual at the suspicious individual determining step. - View Dependent Claims (15)
