WEARABLE TERMINAL DEVICE, PHOTOGRAPHING SYSTEM, AND PHOTOGRAPHING METHOD

1 . A wearable terminal device comprising:

circuitry configured to

receive sensor data from one or more sensors, wherein the sensor data corresponds to a psychological state of a user in possession of the wearable terminal device;

determine, based on the sensor data, the psychological state of the user; and

control, based on the determined psychological state of the user, a photographing interval of a camera.

2 . The wearable terminal device of claim 1 , wherein

the one or more sensors include at least one biological sensor.

3 . The wearable terminal device of claim 2 , wherein

the at least one biological sensor measures physiological conditions of the user's body.

4 . The wearable terminal device of claim 3 , wherein

the physiological conditions include one or more of heart rate, temperature, perspiration, breathing rate, and blood pressure.

5 . The wearable terminal device of claim 3 , wherein

the one or more sensors include at least one motion sensor;

the sensor data includes an indication of a motion of one or more of the wearable terminal device and the user, and

the circuitry is further configured to control the photographing interval of the camera based on the psychological state of the user and the motion.

6 . The wearable terminal device of claim 1 , wherein

the camera is included in the wearable terminal device.

7 . A photographing system comprising:

a wearable terminal device including

a camera configured to capture image data at a photographing interval;

one or more sensors configured to generate sensor data, wherein the sensor data corresponds to a behavior of a user in possession of the wearable terminal device; and

circuitry configured to

transmit the sensor data to one or more external devices,

receive an indication of a behavior of the user, and

determine, based on the indication of the behavior of the user, the photographing interval of the camera, and

control the camera to capture the image data at the determined photographing interval; and

a communication device including

circuitry configured to

receive the sensor data from the wearable terminal device,

determine, based on the sensor data, the behavior of the user, and

output the determination result of the behavior of the user to the wearable terminal device.

8 . The photographing system of claim 7 , wherein

the circuitry of the communication apparatus is further configured to:

determine, based on the indication of the behavior of the user, the photographing interval of the camera, and

control the camera to capture the image data at the determined photographing interval.
