Notification device, notification method, and recording medium having notification program stored therein

A notification method executed by a computer including a processor, the notification method causing the processor to execute a program stored in a memory to perform operations comprising:

• sequentially capturing an image including a facial image of a subject;
• sequentially detecting a face state of the subject on the basis of the sequentially captured image;
• sequentially detecting the face state of the subject by measuring biometric information of the subject on the basis of a specific signal contained in images which are sequentially input;
• giving notification of face guidance information;
• determining whether or not the face state sequentially detected when the notification of the face guidance information is given has changed based on a change in the specific signal;
• and
• when it is determined that the face state has changed based on the change in the specific signal, in a case in which a change of the state satisfies a predetermined transition condition of the face guidance information, controlling the face guidance information for which the notification is given to be switched to a face guidance information corresponding to the transition condition,
• the specific signal being a green signal absorbed by subcutaneous blood hemoglobin in the subject, and
• superimposing a display surface of that displays a mirror image of the subject, and a display surface of a second display section that displays the face guidance information, in a viewing direction so that the display surface of the first display section and the display surface of the second display section are viewable at the same time.

A non-transitory computer-readable storage medium storing a program that is executed by a computer that comprises a processor to control a notification device, the program being executable to cause the computer to perform operations comprising:

• sequentially capturing an image including a facial image of a subject;
• sequentially detecting a face state of the subject on the basis of the sequentially captured image;
• sequentially detecting the face state of the subject by measuring biometric information of the subject on the basis of a specific signal contained in images which are sequentially input;
• giving notification of face guidance information;
• determining whether or not the face state sequentially detected when the notification of the face guidance information is given has changed based on a change in the specific signal;
• and
• when it is determined that the face state has changed based on the change in the specific signal, in a case in which a change of the state satisfies a predetermined transition condition of the face guidance information, controlling the face guidance information for which the notification is given to be switched to a face guidance information corresponding to the transition condition,
• the specific signal being a green signal absorbed by subcutaneous blood hemoglobin in the subject, and
• superimposing a display surface of that displays a mirror image of the subject, and a display surface of a second display section that displays the face guidance information, in a viewing direction so that the display surface of the first display section and the display surface of the second display section are viewable at the same time.
